Our Message to Firefighters

The development of the wood I-joist provided the residential house building industry with many obvious benefits. The wood I-joist was the main component of the “quiet floor” that could span greater lengths, eliminating many teleposts from basements.

There was only one main disadvantage – reduced fire protection. In the case of a fire, the floor joist burned through in about 5 minutes, versus about 15 minutes for a solid sawn 2 x 10 or 2 x 12.This does not give the family much time to get out safely during a basement fire and it does not provide sufficient time for first responders to respond and extinguish the fire. Often when firefighters arrive, they cannot enter the home because the main floor has already burned through. They are just able to prevent the fire from spreading to adjacent houses.

Many firefighters in North America (as well as the many men, women and children attempting to escape a basement fire) lost their lives as they crashed through floors that appeared intact. To reduce these hazards to families and first responders, we designed a state-of-the-art facility with fully integrated coating technology to coat our products with a fire rated intumescent paint that is very difficult to ignite.   


Our Fire Rated I-joist, which we refer to as "SafeJoist", is much more difficult to ignite and takes far longer to burn through, giving families time to get out of the home safely and reducing the hazard to firefighters. For essentially the same cost, builders are able to provide the public with a safer home by using our Fire Rated "SafeJoist".

For every gallon of PKshield used in our coating process, we contribute a royalty to the Canadian Breast Cancer Foundation for research to find a cure for cancer.
