GThurm Windows Feature Pultruded Polyurethane Composite technology

22 February 2011

Graham Architectural Products has launched GThurm a line of high-efficiency windows that use pultruded polyurethane composites for the lineals.

The first commercial installation of the GThurm windows took place in late 2010 at the Bayer CropScience LP Clayton (N.C.) Development and Training Facility. A total of 76 windows were replaced at the building, which is roughly 50 years old. The before/after difference was immediately noticeable, according to John Rock, who was the site manager at Clayton during the time of the installation.

""I could actually feel a breeze on a windy day when I stood next to the old windows,"" said Rock. ""The new windows have greatly increased the comfort of the people who work in this facility. Furthermore, we expect to realize energy savings of roughly 12 percent, which is significant,"" he continued.

Graham Architectural Products' GThurm high-efficiency window products are said to be the first American-made architecturally rated (AW) windows to feature thermal transmission measures as low as U 0.18 (R 5.5), using readily available insulating glass. GThurm windows feature a unique polyurethane resin supplied by Bayer MaterialScience LLC that contains no volatile organic compounds (VOCs).

According to Graham Architectural Products, 80 percent continuous stranded glass content is combined with 20 percent resin to produce window lineals using the pultrusion process.

Having the Bayer facility in Clayton, N.C., as Graham Architectural Products' first commercial application for our GThurm windows made perfect sense, according to Jim Eisenbeis, director of marketing, Graham Architectural Products. ""Bayer MaterialScience LLC has been a strategic partner in this venture from the beginning, and we are pleased to be able to cite the Clayton project as a benchmark for all future applications of our high-efficiency GThurm windows.""
