Heat-Insulating uPVC Windows

Heat-insulating uPVC windows keep interiors cooler in strong heat. Here's how.

How we achieve it

Look for this

  • uPVC profile that doesn't conduct heat like metal
  • Multi-chamber design that traps air
  • Double glazing to slow heat through the glass
  • Tinted glass for strongly sun-facing walls

Built in at fabrication

uPVC naturally resists heat transfer, and with multi-chamber profile and the right glazing, interiors stay noticeably cooler through the afternoon — built to suit each opening.
