A Solution for Our Industry’s Thermal Challenges

It’s important to note that doors and windows influence how well a building is able to insulate and retain heat. The best products keep excess heat out and lower your monthly energy bills. 

In Santa Rosa, where heat and humidity can be a problem in the summer, we realized the need to create a product line that combated these unique challenges for our customers. 

Our Artisan Thermal Series is composed of cutting-edge glass-reinforced polyetherimide (GRP).

This material is a great deflector of heat and a solid building material, making it the ideal building block for our steel window frames in Santa Rosa.

In Santa Rosa, many of our competitors simply use insulated glass, which doesn’t nearly do the job of restricting thermal transfer from the glass to the frame of your window or door. 

A lot of our competitors also have limited design options when it comes to developing energy-efficient Santa Rosa steel windows and doors. 

In contrast, we have an official patent for this product series that gives us free rein to customize our energy-efficient windows and doors the way we choose. 

This allows a client to lower their energy bills and achieve a modern design that will complement their property.
