How Brazilian Hardwoods Perform in Real Exterior Conditions (By Species)

Every Brazilian hardwood species performs differently once it’s installed outdoors — not because some woods are “good” and others are “bad,” but because exterior conditions matter.

Sun exposure, airflow, fastening method, and application type all play a role in how hardwood decking, siding, ceilings, and porch flooring behave over time. In real-world projects, we’ve seen excellent materials succeed — and fail — based entirely on how and where they were used.

To make these differences easier to understand, we created a visual performance chart that scores common Brazilian hardwood species based on real exterior conditions, not lab tests or manufacturer claims. These ratings reflect decades of customer feedback, field results, and conservative recommendations developed through hands-on experience supplying and installing hardwoods across a wide range of climates.

This guide is designed to help you choose the right hardwood for your specific application — and just as importantly, the right installation method — so expectations align with long-term performance.

How to Read This Performance Chart

This chart compares Brazilian hardwood species based on how they perform under specific exterior conditions. Each category is scored on a scale from 1 to 5, where:

  • 5 = Highly recommended and proven to perform well in that condition
  • 3 = Neutral or situational — performance depends heavily on exposure and installation
  • 1 = Not recommended due to predictable issues in real-world use

All species receive a score of 5 for decking because they are all suitable decking materials. The differences emerge as conditions become more specific — such as sunlight exposure, fastening method, or application type.

These ratings are intentionally conservative. They reflect what tends to go wrong when projects fail, not ideal installations under perfect conditions. In many cases, a lower score does not mean a material can’t be used — it means it requires tighter controls or greater tolerance for change.

Exterior Hardwood performance application grade chart

What These Scores Are Based On

This chart scores each hardwood species across three real-world factors that consistently influence long-term results outdoors. The goal is not to “rank” woods in a vacuum, but to show how conditions and installation choices change what’s realistic for a given project.

1) Application Type

Different exterior uses create different stress levels. Decking takes the most abuse, while ceilings and covered porch areas typically see less direct sun and less moisture cycling. Siding adds its own variables depending on airflow, exposure, and how the boards are installed.

2) Fastening Method

How you attach the boards affects stability, movement, and long-term appearance. In general, surface screws provide the strongest mechanical hold, while hidden clips and CAMO edge fasteners can be excellent in the right conditions—but may be less forgiving in high-exposure installs.

Did you know? At BWD, we focus exclusively on hardwood decking—so every product we offer is built with hardwood performance in mind. BWD Deck Clips are engineered specifically for dense hardwoods, not adapted from multi-material systems, and are available exclusively to our hardwood customers. See how major clip systems compare here.

3) Sunlight Exposure

Sun exposure is one of the biggest drivers of movement, checking, and aesthetic change. “Heavy sun” installs behave differently than shaded or covered projects, and some species hold color and stability better than others when they’re constantly blistered with UV.

Bottom line: this chart is designed to help you match the species, application, and fastening method to the exposure conditions you actually have—so expectations align with long-term performance.

don’t want to go into too too great a

[Music]

detail all right welcome back to

Brazilian Wood Depot’s YouTube channel

my name is Sam and I’m going over a

chart that I put together and I think

it’s going to be really helpful for a

lot of people out there I spend a lot of

time talking about this topic and kind

of putting it into a visual resource I

think is going to be helpful but I want

to explain some things the chart that

we’re talking about I’m calling bw’s

guide to exterior hardwood applications

by species I know it’s a bit of a

mouthful but basically as as you

probably know we sell uh a handful seven

technically different hardwood species

uh for decking and sighting and exterior

applications well these seven different

species of Hardwoods have different

performance characteristics based on

different conditions so I’ve basically

made a a visual chart and scored the

different species based on these

different conditions so I’m going to

shrink this video down so we can look at

this chart together and I’m going to go

through it from top to

bottom all right here’s our chart bwd

guide to exterior hardwood applications

by species first thing you’ll notice up

here is that we are breaking it down

into three categories application deck

fastening and sunlight exposure

applications are decking siding tongue

and groove ceiling which is very popular

Believe It or Not uh and porch tongue

and groove they’re slightly different

because they have different exposures um

and then deck fting surface screws

Groove for Clips camo Edge fasting and

sunlight exposure heavy moderate and

little to none so before we get into the

species cuz I’m going to go by each

species and then go across I want to

mention a couple things everything gets

a five because everything makes good

decking uh but that’s pretty broad

because the conditions are going to get

more specific uh like I said then we’re

going to get a fasten sunlight exposure

I could have just not had this but I

thought it was nice to have it so

everybody understands that they all make

good decking but then we’re going to go

more specifically into different

conditions um I guess that’s the only

thing I want to mention first let’s just

go ahead and start with eay then okay so

we already talked about decking get gets

a five rain screen siding gets a five

it’s very stable ceiling porch TNG

everything good there surface screws

five good why would eay get a four on

these and not a five what well if it’s

my opinion and it is my opinion that

surface screws is the best turn this

down if surface screws is the best way

to install it’s the most secure uh

mechanical

Fastener um available then the other two

have to be four so does eepe do great

with a Groove board and do well with

camo yes they should really technically

probably be able to get fives but um I

still think surface screws are better so

I get it a five and these are four um my

colleague thinks these should be five

and that’s fine it works well but

surface screws is always stronger uh

eBay does well and heavy moderate and

little to no sunlight exposure because

ePay is the most stable and you don’t

have any problems so that’s pretty easy

moving on to

kumaru we already talked about this

everything gets a five for decking rain

screen siding not as much because you

have to use use the clips and kumaru is

not as stable um ceiling don’t have much

sunlight exposure does well porch TNG

we’ve been doing porch TNG with kumaru

for a long time typically the 3 and 1

half inch tongue and groove we like that

that works great surface screws that’s

the way to go with kumaru for sure

because it’s not as stable uh Groove

boards with Clips if it was in moderate

sunlight exposure it’ be fine heavy

sunlight exposure not so great so it

gets a three which is kind of like my

neutral number uh one is like I really

don’t recommend it five is I highly

recommend it and three is like neutral

eh hit or miss so for Groove boards it

gets a three again it would do fine if

the sunlight exposure was minimal but uh

that’s why it gets that camo exposure or

camo Edge fastening rather also gets a

three again in heavy sunlight exposure

probably not great and minimal sunlight

exposure prob really just fine um so

that’s why it gets a three heavy

sunlight if it’s surface screwed it’s

fine if we want to use one of these

systems uh I don’t like it so much

that’s why it gets a three and in

moderate sunlight exposure you know it’s

better than heavy so four and then

little to none five because Kum does

well when it’s not being blistered with

sun that’s makes makes it want to act up

a little

bit okay moving on to

garpa decking we already talked about

that gets a five check that’s a weird

check let me start that over

here check uh r screen siding check

garpa is very stable like eBay it does

well in all of these conditions the only

reason it gets a four here is because I

don’t have a whole lot of experience

with using it as porch TNG uh it would

be a 5 in uh TNG for porch decking I I’m

sure we’ve done it but uh just because I

can’t really remember doing it too much

it’s just going to get a four I think it

would do fine it probably would earn a

five I just don’t have the data to

support it um surface screws like

everything that you’ll notice everything

gets five with surface screws so so does

garpa uh garpa does really well with

grooved boards for Clips it gets a four

I don’t really have any problems with it

also gets a four with camo um arguably

they could it could be getting a five

but I think four is fine um it does well

in all sunlight conditions so it gets a

five on all three so garpa and eepe if I

were to add them up probably would have

the highest scores uh garpa is

underappreciated and um very cost

effective so I always try to remind

people about

garpa all right moving on to Tiger Wood

take a sip of

water

okay decking gets a five we’ve already

talked about that rain siding I have a

lot of experience with it it gets a four

not quite as stable as epe so it’s going

to get a little ding there but still

gets a forward it’s pretty good uh

ceiling we’ve done a lot of ceilings

with Groove and they look awesome and uh

as you can see most of them most of

these get a five and ceiling because

ceiling doesn’t get much sunlight

exposure just by Nature so um tigerwood

also gets a five there porch TNG don’t

have a whole lot of experience with a 5

in tigerwood I mean I know we’ve done it

probably many times um I wouldn’t expect

there to be an issue and I’ve not heard

of any issues uh but since I don’t have

as much data on it as I do like the eBay

and kumaru I’m just going to get it a

little ding as a four because

I just don’t have as much data on it

surface screws like everything else five

Groove boards with Clips yeah if it’s if

it’s a moderate if it’s one of these

sunlight conditions then yes then maybe

it’s a four but if it’s this sunlight

condition then it’s probably a two so

overall tigerwood gets a three kind of

neutral on it depending on sunlight

exposure uh camo Edge fastening

yeah yeah not so much especially in

these two sunlight conditions heavy and

moderate it’s definitely a two in little

to none H it might even get a four in

little to none sunlight condition

um so all right let’s go to the

conditions himself the reason that it

gets a one in heavy sunlight condition

is because you start losing the black

veins that run through and that are so

characteristic for Tiger Wood if you’re

going to lose those in a matter of

months or a few years uh to an all gray

color then what’s the point of using

tigerwood in the first place not to

mention tigerwood is not one of those

that is very pretty when it turns gray

like for instance purple heart which is

why Purple Heart gets a five um so

overall heavy sunlight conditions I

always advise people against Tiger Wood

some people don’t listen to me and

presumably they’re happy with it but I

generally I don’t recommend it uh same

logic going into moderate moderates

better than heavy but still don’t

recommend it it does fabulous in little

to no sunlight conditions it holds its

color it keeps its black veins and uh it

works really well good moving on to Masa

which is short for Masa and Duba I just

didn’t want to type it all in um all

right decking five yeah we know that

rain screen siding five good yes I have

a lot plenty of experience and never

really any issues TNG ceiling everything

gets a five except for one of them so

yes Masa gets a five and I have

experience with it and it looks great uh

porch TNG don’t have much experience

with it for a porch TNG again like I

keep saying I’m sure we’ve done it many

times but I just don’t really have the

data in my

mind so anyways uh it it it could

probably earn a five but because the

data is not there to support it four

surface screws just like everything else

gets a five and it doesn’t really

typically have any problems with group

for Clips or camo Edge fastening

especially in moderate to little

sunlight exposure I would probably give

it a

three I’d probably give it a three under

heavy sunlight conditions for these two

methods of

fastening um actually I have a cool line

I can use for these two methods of

fastening

under this condition is probably a three

but those but these two method methods

of fastening in these two get a four and

a

five that may have been more confusing

than anything anyways uh heavy sunlight

condition master and Duba generally does

fine um and then of course in the other

two conditions master and Duba does fine

good moving along to the maybe the

Oddball of the group here in terms of

scoring of course five here wow are only

one there’s some reasons for that uh one

we’re assuming that rain screen sighing

is going to have a moderate to heavy

sunlight exposure typically these two

things typically go together um so

therefore and purple heart just very

similar to kumaru is just not that

stable um so therefore and not only that

it’s purple so most people don’t want

purple siding so all of that considered

it gets a one we really don’t do much

Purple Heart siding which I’m not

surprised about um we have done a little

bit of it but anyways it gets a one in

Rain screen

sighting uh ceiling TNG well it goes

from purple to Brown quickly in sunlight

but not in sunlight it takes a long time

which is why people typically don’t use

it on the ceiling they don’t want a

purple type wood ceiling so for that

reason it gets a one performance would

probably be fine but purple ceiling

that’s why it gets a one uh also purple

porch that gets a one not so much

performance probably but color surface

screws yes we definitely want surface

screws with purple heart because as you

can see I’m not thrilled on these

methods of fastening with purple heart

especially with these two sunlight

conditions so this one together is a

no but these two with this condition

probably gets more like

uh

four that make sense it gets a two in

these conditions but a four in little to

no sunlight anyways the reason it’s

going 5 4 1 here is because we want the

sunlight to help it turn brown because

most people don’t want it purple these

two conditions will allow it to turn

brown very quickly in a matter of weeks

maybe typically somewhere around 6 weeks

um maybe in moderate sunlight maybe it’d

be more like I don’t know eight or 10 so

that’s the deal with purple heart most

of these

scores most of these scores have to do

with the fact that in these conditions

they’re not turning brown they’re

staying purple let me do a better job in

these type of conditions especially this

one I’ll put a lot of circles here

especially that one it’s not turning

purple very quickly it’s going to take a

long time so therefore they get ones but

we love Purple Heart in heavy sunlight

conditions boat docks that kind of thing

purple heart’s great all right for the

last one the Southeast Asian hardwood

Brown

blow of course it gets a five in decking

rain screen sighting four only because I

don’t have a whole lot of data yet but

everything seems fine um but it would be

in the you know a four in like sorry in

these two sunlight condition is better

so anyways moving on uh ceiling we’ve

done lots of ceilings Fabulous Five

porch T we’ve done a lot of that five

surface screws like everything five

Groove for

Clips Brown bow seems to have a little

more expansion contraction especially in

the heavy sunlight exposure conditions

so for that reason um it gets a three

like a neutral on these two fating

methods as you can see and I’m just

realizing this now

they’re all pretty much they get the if

you get a lower score with grooves it’s

pretty

consistent tigerwood oh yeah that’s true

I would prefer Clips with tigerwood than

camo anyway I’m just pointing out that

these two pretty much are always the

same score across the board uh which I

hadn’t noticed before but it is true let

me clear this again all right so anyways

Brown bow uh group for clips and Camo

I’m neutral on it because again they it

would do really fine here maybe a four

or five in that that condition but uh

maybe a two or a three in this condition

so overall for these two fastening

methods um I’m just going to stay

neutral and say three really i’ I’d

prefer to see people using just face

screws on Brown bow um and then finally

sunlight conditions yeah heavy it t it

tends to check a little bit more than

other species all species check to some

degree Brown blow seems to do it a

little heavier so it’s going to get a

three and heavy um same reason moderate

it’s not it’s not going to experience as

much checking so it gets a four there

and it’s doing fabulously in these low

sunlight conditions like porch TNG and

ceiling and covered decks things like

that which I think that pretty much

covers it

um I hope this was helpful um hopefully

I didn’t miss anything but if you have

any questions give us a call like I said

I’m trying to keep this video short so

uh stay tuned I’ll have another video

coming up soon but I hope this helped

thanks a

lot I just wanted to add a final

disclaimer to this video and remind

anybody who’s watching that uh the

scores on this chart that I went over in

this video they’re my opinions my

opinions that I’ve developed over the

course of many years with lots of

customer feedback and my opinions might

be slightly different than somebody else

here um even within Brazilian Wood Depot

uh my colleagues would probably fill in

this chart slightly differently and

that’s totally fine that’s okay um I

also like to put out there that I’m very

conservative when it comes to this stuff

because customers tend to call me if

they have issues and not when

everything’s going great so these scores

are probably pretty aggressive in terms

of being very conservative I like things

to go down and everything to be happy

with everyone so my advice tends to be

pretty conservative but anyways hope you

enjoyed the video go out there and watch

some more and uh thanks for

watching for

Exterior Hardwood Performance, by Species

Below is a species-by-species summary of how each hardwood tends to perform across application type, fastening method, and sunlight exposure. These notes are meant to match real-world expectations—not ideal installations under perfect conditions.

Ipe

The industry benchmark for stability and long-term exterior performance across decking, siding, and ceiling applications.

  • Best uses: Decking, rainscreen siding, ceilings, porch T&G
  • Fastening guidance: Surface screws provide maximum mechanical security; clips and CAMO also perform well when installed correctly.
  • Sun exposure: Highly reliable in heavy, moderate, and low-sun conditions; one of the most dimensionally stable hardwoods available.
  • Key takeaway: If maximum stability with minimal surprises is the goal, Ipe sets the standard.

Cumaru

A dense, high-performance hardwood that delivers strength and durability when properly matched to exposure conditions.

  • Best uses: Decking, porch T&G, ceilings; siding performs best with proper detailing and airflow.
  • Fastening guidance: Surface screws are strongly recommended, especially in higher sun exposure. Clips and CAMO can work in lower-exposure installs.
  • Sun exposure: Excellent in low-sun or covered applications; in heavy sun, fastening choice and spacing discipline become more critical.
  • Key takeaway: Cumaru is a powerhouse hardwood—just align species, exposure, and fastening method correctly.

Garapa

Bright, clean appearance paired with dependable exterior stability across a wide range of applications.

  • Best uses: Decking, rainscreen siding, ceilings; performs strongly across exterior conditions.
  • Fastening guidance: Performs well with surface screws, clips, and CAMO in most installations.
  • Sun exposure: Handles heavy, moderate, and low-sun installs reliably.
  • Key takeaway: One of the most stable, underappreciated, and cost-effective hardwood options available.

Tigerwood

Bold striping and dramatic contrast make Tigerwood visually striking when used in the right exposure conditions.

  • Best uses: Decking and ceilings in controlled exposure environments.
  • Fastening guidance: Surface screws are the safest choice; hidden systems become less forgiving as sun exposure increases.
  • Sun exposure: Best suited for low-sun installs; heavy UV can reduce the dramatic contrast over time.
  • Key takeaway: Choose Tigerwood for the look—then protect that look from excessive UV exposure.

Massaranduba

Dense and durable with consistent coloration, offering predictable performance across exterior builds.

  • Best uses: Decking, rainscreen siding, ceilings; a dependable all-around performer.
  • Fastening guidance: Surface screws are preferred; clips and CAMO can work, with greater caution in heavy sun.
  • Sun exposure: Generally performs reliably from heavy to low sun exposure.
  • Key takeaway: A dense, stable hardwood that performs consistently across many exterior conditions.

Purpleheart

A specialty hardwood known for its dramatic color shift under sunlight exposure.

  • Best uses: Specialty decking and high-sun installs where rapid color change is acceptable or desired.
  • Fastening guidance: Surface screws are strongly preferred; hidden fastening becomes higher risk in strong sun exposure.
  • Sun exposure: Sunlight drives rapid color change; lower sun exposure retains purple tones longer.
  • Key takeaway: Purpleheart decisions are often about managing color expectations as much as performance.

Brown Balau

Strong performance characteristics with best results in covered or lower-exposure environments.

  • Best uses: Decking, ceilings, porch T&G; excels in covered or lower-sun applications.
  • Fastening guidance: Surface screws are preferred; hidden fastening can be more sensitive in heavy sun due to movement.
  • Sun exposure: More prone to checking in heavy sun; performance improves as exposure decreases.
  • Key takeaway: Excellent in lower-sun installs—use surface screws and manage expectations in high UV environments.

Deeper Resources for Species Selection, Installation, and Performance

This guide is meant to provide a high-level framework for understanding how Brazilian hardwoods perform under real exterior conditions.

Fasteners & Installation Methods

If you’re unsure where to start, the Decking Wizard and Installation Guides are the fastest way to translate this chart into a real-world plan that matches your project conditions.

Final Thoughts on Using This Guide

This chart and walkthrough are not meant to replace good judgment, proper installation, or real-world experience. They’re designed to help set realistic expectations before material is selected and installed.

The performance scores shared here are intentionally conservative. They reflect what tends to cause problems when projects fail—not what’s possible under ideal conditions. In many cases, a lower score doesn’t mean a species can’t be used; it means the margin for error is smaller and installation details matter more.

If there’s one takeaway from this guide, it’s this: matching the species, fastening method, and exposure conditions correctly is more important than chasing a “perfect” hardwood. When those pieces align, all of these materials can perform beautifully for decades.
