It is also a challenge to recycle, increasing the chances that it will be incinerated or disposed of in a landfill. Broadloom carpet cannot be readily repaired if... Read more

Hi everyone,

As you may know the ICC has changed the way the IECC will be written in the future and most of us think that will reduce the stringency of the future energy codes that are the biggest lever in the fight against climate change within the buildings sector.
