IPE Decking
A South American hardwood, IPE (Tabebuia serratifolia) is one of hardest woods on Earth. Because of its hardness and ability to resist decay, IPE is superior for decks, patios, piers, boat docks, outdoor furniture, walkways and poolside benches. IPE requires no chemical preservatives to keep it smooth and splinter free and it is naturally safe.
With a durability rating of 25-plus years by the U.S. Forest Products Lab, IPE is competitively priced and comparable to cedar, redwood or composite decking.

Wood Selection Tips
Not sure which grade to select when shopping for wood?

  • Grade A: FAS / F1F, Select and Better: This is the highest quality of hardwood lumber and will yield long, clear pieces with very little waste.
  • Grade B, #1, Common: A great value for the woodworker looking to get several long, wide cuts, or longer narrow cuts in a board.
  • Grade C, #2, Common: This grade of lumber is good for the woodworker looking to use the natural characteristics (knots, worm holes, discoloration) or looking for 1-foot or 2-foot cuts. Also good for small crafts and interior furniture parts.

Thermally Modified
Lumber Products

Thermally modified hardwoods & softwoods have these unique features and are categorized based on a specific treatment temperature.

Dimensional stability is achieved because of the decrease in absorptive qualities and lower equilibrium moisture content.

Color and appearance is an attractive golden brown and even color at all depth.

Resin is almost fully removed.

Fire resistance is the same as non-treated wood and is in fire class D.

Resistance to insect attack and termites is significantly increased.

Biological durability tests conducted in Europe in EN113, ENV 807 standards showed significantly improved levels of resistance against fungi attack depending on treatment temperature.

Weather resistance – it will start to gray without coating in approximately one summer.

Ground contact in deep ground applications is not recommended where structural performance is required.

Emissions disappear almost totally with time or after coating.   

Environmental purity is achieved since thermally modified wood is made without insertion of any chemicals.   Also depending on species may be eligible for LEED credits.

General Strength is in correlation with density.

Thermal S Products are recommended for interior use in furniture, mouldings, fixtures, flooring, and cabinetry.

Thermal D Products are for both exterior and interior applications:

  • Poplar – siding, exterior mouldings, soffit & fascia
  • Pine – Horse barn applications, siding, fencing, decking, garden furniture, etc.

How long does thermally modified wood last?

Although evidence from long-term experience of the use of thermally modified wood is not yet available in the U.S.; European tests have shown that the material’s resistance to decay is far superior to that of untreated softwoods and equal that of many tropical hardwoods.

More than just a lumber company, Lewis Lumber Products is dedicated to providing the highest quality lumber products, including FSC® products to meet your needs.
