Pacific Thermal System

The Pacific Thermal System can add up to 50%* more thermal efficiency to what double glazing alone can provide. This is achieved through a thermally efficient, or thermally broken frame, which unlike standard aluminium joinery is highly heat and cold conductive. The thermal frame has a nylon barrier which, in essence, reduces the thermal transference of cold or heat through the frame and considerably reduces the chance of condensation, thus keeping the inside of your home warmer, drier and more comfortable.


  • Polyamide thermal barrier 
  • Passive ventilation options
  • Double glazing and Triple glazing capability up to 46mm IGU

*The Pacific Thermal System when combined with higher performing glass (double glazed IGU with Argon gas and a Low E coating) can add up to 50% more thermal efficiency than standard double glazing alone.
