Innovations That Revolutionized Construction
Sisalkraft® was launched in the 1950's and evolved into what we know today as window flashing. Until that time little waterproofing was done around the windows and doors. When it was done, the flashing was made of metal. The invention of rolled flexible flashing was revolutionary for being simple to install and very cost effective.
In the 1960's Fortifiber invented the modern weather-resistive barrier with Jumbo Tex® asphalt saturated kraft. Roofing felt had been used for many years in this application. But it was heavy, expensive, and tore too easily when used on walls. Jumbo Tex solved all these problems and is still a very popular product. Fortifiber was the first company to combine its expertise in weather-resistive barriers with window flashing to form a complete moisture control system for walls.
WeatherSmart® housewrap was launched in 2006 by blending decades of weatherization knowledge with the most advanced polymer science. Widely recognized as one of the most technologically advanced housewraps available, Fortifiber's record of innovation continues.
