PVC
PVC windows provide good insulation, are easy to maintain, and are affordable, so it’s little wonder that they’re our most popular windows.
Hybrid
Hybrid windows are made of PVC with the frames and sashes covered in aluminum cladding. This adds rigidity and elegance to the window, for unbeatable value.
Double hybrid
Double hybrid windows combine the good looks and superior durability of aluminum with the energy efficiency of PVC. They feature aluminum on the surface, indoors and out, over a frame (core) made of AAMA-certified recycled PVC.
Wood
Isothermic is a proud distributor of Belisle architectural windows and doors. We offer a variety of options in western red cedar, white oak, or mahogany.
Belisle windows are made exclusively of solid wood. They do not contain laminated wood, jointed wood, or plywood.

Interior and exterior colours
We offer a wide variety of standard colours and we can reproduce any colour you like—just give us your colour code.
Latches
Choose from the discrete flat-profile NOVA Slim or the classic model with a more rounded profile.
Depending on the look you want, you can choose a flat latch that matches the window while being barely noticeable or a more conventional rounded mechanism.
Mullions
Mullion colour can be matched to the casement window, both inside and out. Pick from a number of mullion and transom options to match your architectural design.
