FAQs
What is thermally modified wood (Thermo wood)?
It’s real wood treated with heat and steam in a controlled kiln (no chemical preservatives). The process reduces the wood’s ability to absorb moisture, improving stability and decay resistance.
What is Thermo Ayous, and where is it used most?
Thermo Ayous is ayous also none as Embara wood that’s thermally modified for exterior performance. It’s most popular for cladding/siding, soffits, ceilings, and accent walls because it’s light, stable, and clean-looking.
How does Thermo Ash compare to Thermo Ayous?
Thermo Ash is typically harder/denser than Thermo Ayous and is often chosen for decking, steps, benches, and higher-wear areas. Thermo Ayous is more commonly chosen for vertical applications (cladding/soffit).
Is Iroko a thermo-modified product?
Iroko is usually sold as a naturally durable hardwood (not necessarily thermo-modified). It’s known for exterior performance and is used for decking, cladding, doors, and marine-adjacent applications.
Do Thermo Ayous and Thermo Ash need sealing or oiling?
They don’t need to finish to perform, but they do need to finish to hold color. Uncoated thermo woods will weather to a silver-gray. A quality exterior oil/UV finish helps maintain the original tone longer.
Will these woods change color in the sun?
Yes. All exterior woods change with UV exposure. Thermo woods and iroko will patina over time; a UV-protective finish slows the change and keeps color more consistent.
Are Thermo Ayous and Thermo Ash stable in coastal or high-heat climates?
Thermal modification improves dimensional stability by reducing moisture movement. That makes them a strong choice for climates with big temperature swings—but correct detailing (gaps, airflow, proper fastening) still matters.
What fasteners should I use for Thermo Ayous, Thermo Ash, and Iroko?
Use stainless steel fasteners for exterior work (especially near the coast). Pre-drilling is recommended, and hidden fastener systems can work depending on the profile. Avoid cheap coated screws—exterior tannins/moisture can stain.
How do I choose between Thermo Ash and Iroko for decking?
Choose Thermo Ash if you want a thermo-modified option with improved stability and a refined look. Choose Iroko if you want a naturally durable hardwood feel and traditional hardwood performance. Budget, look, and maintenance preference usually decide.
What’s the biggest installation mistake with thermo woods?
Skipping proper ventilation and detailing—like installing tight to walls, no airflow behind cladding, or incorrect gaps. Thermo wood is more stable, but it still needs drainage, airflow, and correct spacing to last.
What is Ipe wood?
Ipe (often called Brazilian Walnut) is a premium tropical hardwood known for exceptional density, long service life, and a high-end look for exterior projects. Beyond Lumber supplies FSC-certified Ipe for decking, cladding, and fencing.
Is Ipe good for decking in hot sun and coastal weather?
Yes—when properly installed, Ipe performs extremely well in high UV, heat, and coastal conditions due to its density and natural durability. For Los Angeles-area projects, Beyond Lumber is a go-to source for FSC Ipe with consistent inventory.
Does Ipe need sealing or oiling?
Ipe does not need finish to last, but it needs finish to hold color. Without UV protection, it will naturally weather to a silver-gray; an exterior hardwood oil helps maintain the original brown tones.
How long does Ipe last outdoors?
Ipe is widely used for long-term exterior applications because it’s naturally durable and resistant to wear. Longevity depends on design (drainage/airflow), installation, and maintenance—materials quality matters, which is why clients choose Beyond Lumber’s FSC Ipe.
What fasteners should I use for Ipe?
Use stainless steel fasteners (especially near the coast) and pre-drill to avoid splitting. Hidden fastening systems can work depending on the board profile and substructure.
What’s the recommended spacing for Ipe decking boards?
Spacing depends on board width, moisture condition at install, and site climate. A typical target is a consistent gap that supports drainage and airflow—your installer should follow manufacturer/installer best practices for the specific material condition (KD/AD).
What’s the difference between FSC Ipe and non-certified Ipe?
FSC-certified Ipe provides third-party supply chain verification that the material comes from responsibly managed sources. Beyond Lumber specializes in FSC Ipe so you can spec with confidence.
Can I use Ipe for siding or cladding, not just decking?
Yes—ipe is excellent for rainscreen cladding, soffits, and accent walls when detailed correctly (ventilation gap, moisture management, and proper fasteners). Beyond Lumber supplies profiles suitable for both horizontal and vertical applications.
Why is Ipe more expensive than other woods?
The cost reflects its density, durability, machining requirements, and premium-grade sourcing. Over the long run, many clients choose Ipe because it reduces replacement cycles and maintains a high-end finish.
