Environmental choice

Building with Renewable Resources

In choosing wood as a construction material, you are choosing the only building material that is made from renewable resources.

Did you know?

Due to sustainable forest practices, the volume of wood in our forests has actually increased by 35% in the last 25 years.
International Beams I-Joists are made from two wood products that assist in achieving total utilization of each tree harvested:

• Flanges are made from small dimension lumber that is sawn from small trees and the tops of larger trees
• Webs are a special grade of oriented strand board made from underutilized wood species

Our I-joists are among the most environmentally friendly building products available.
When considering total environmental impact including extraction of raw materials, energy required during manufacturing, emissions from manufacturing operations and energy efficiency of buildings.


Formaldehyde Free

Often referred to as “off-gassing,” formaldehyde emission occurs naturally in food and wood and is even present in human blood. Concerns are generally limited to urea formaldehyde adhesives used in the manufacture of wood panel products intended for interior use, where moisture resistance is not required.

International Beams engineered wood products are urea formaldehyde-free.

The moisture-resistant adhesives (resins) used in the manufacture of our I-joists, OSB Rimboard and LVL have such low levels of formaldehyde emission that they are exempt from even the most stringent international standards.

Data from a variety of sources can support this claim.

formaldehyde1Formaldehyde is a simple chemical made of hydrogen, oxygen and carbon. It occurs naturally and is the product of many natural processes:

• It is made by our bodies and is in the air. Plants and animals also produce it.
• It is in many fruits and vegetables and is a by-product of cooking certain vegetables, such as brussel sprouts and cabbage.
• The chemical breaks down quickly and is metabolized to simple carbon dioxide. Our bodies readily break down the low levels to which we are exposed every day.

Formaldehyde is also a product from combustion associated with the burning of kerosene and natural gas, automobile emissions, and cigarettes. It is an important industrial chemical used in the manufacture of numerous consumer products, including permanent press fabrics and even toothpaste.
