Solving Thermal Challenges

With metal frame doors and windows, manufacturers often struggle to address the thermal challenges that come from losing or gaining heat where the glass meets the frame. While others offer insulated glass designs that fall short of solving the thermal transfer along the frame, our Artisan Series introduces a GRP (glass reinforced polyetherimide) which acts as a non-conducting material to strengthen the build and reinforce thermal performance.

This translates to higher energy efficiency, climate resistant builds, and a more controlled thermal environment thanks to our innovative designs and development.
