Why Is Our Lumber Better For You & The Environment?

Healthy homes are built with responsibly sourced materials, and don’t release chemicals (VOCs) into the air you and your family breathe. That's why every Landmark Home is built predominantly with Engineered Lumber. This product is known as Laminated Strand Lumber (LSL). It’s a product that is good for the environment, 200 times stronger than traditional wood and meets green building standards.

Formaldehyde Free Lumber

Formaldehyde is a widespread, naturally occurring and commercially produced chemical substance. Several health agencies also consider formaldehyde a carcinogen. Humans produce and use formaldehyde in normal biochemical reactions. In industry, this chemical is widely used as a building block chemical due to its reactivity and versatility. Increased public awareness about formaldehyde’s potential health effects has led to concerns about the adhesives used in wood-based products for residential home construction.1

The adhesives used to make engineered wood products are classified under CARB and the federal formaldehyde standard as “no added formaldehyde” or “ultra low-emitting formaldehyde".1

Green Building Council Approved

The U.S. Green Building Council’s LEED, define and categorize composite products differently than CARB and the federal formaldehyde standard. LEED includes engineered wood products in their definitions. The adhesives used to make engineered lumber are classified under CARB and the federal formaldehyde standard as “no-added formaldehyde” or “ultra low emitting formaldehyde.” The adhesives used in Engineered lumber have “no added urea formaldehyde resin” as defined by LEED.1

Better For The Environment

Engineered wood timberlands provide clean air and water, wildlife habitat, renewable energy, and a sustainable supply of wood to build our homes and countless products we all depend on every day. Additionally, engineered wood forests contribute to climate change, millions of acres of forests have an important role to play in mitigating climate change by absorbing CO2 from the atmosphere and storing carbon in the wood products produced.2

Let's Recap!

Overall, engineered lumber is a superior wood product. It’s E: It’s sustainable and helps us preserve our forests. It enables us to deliver an ultra-strong home. Offering unparalleled durability, longevity. It is significantly higher quality than traditional dimensional lumber. And it’s healthier, meeting green building codes.
