THE FENESTRIA DIFFERENCE

Why choose our windows?

Superior-quality products made in Québec

01Optimized Sealed Units

Our sealed units stand out from the competition with their 1 1/4" double-pane and 2 1/2" triple-pane glazing — noticeably superior energy performance and sound insulation.

02Ceramic & Swisspacer Spacers

Our sealed units feature seamless ceramic spacers, giving the structure greater rigidity, and Swisspacer, the material with the lowest thermal conductivity in the world, to maximize energy performance and minimize the risk of seal failure — essential for our northern climate.

03Low-E Climaguard 8071

Our Low-E coating maximizes visible light, heat gain and energy efficiency for the northern climate, thanks to technology built directly into the glass. Unlike standard films, there is no risk of discolouration, peeling, bubbling or sun-related defects over time — a guarantee of long-term durability and efficiency.

04Neoprene Weatherstripping

Neoprene is an excellent flexible, watertight insulator — it doesn't dry out or crack like standard rubber. Better sealing, less risk of mould, and reinforced insulation.

05Thick Welded 5 5/8" Frames

Our windows feature a thick frame with multiple insulating air chambers, allowing the glazing to sit in the warm part of the wall. Galvanized steel reinforcement inside the mullion for larger windows.

06uPVC Profiles

Pure uPVC, neither blended nor recycled. Our frames are made from uPVC more than double the thickness of standard frames. Superior resistance to UV and yellowing, no porosity, easy cleaning and ultra-rigid structures, maximizing both insulation and soundproofing.

07Durable Hardware

All hardware is corrosion-resistant stainless steel with a 25-year warranty, and sliding windows are fitted with automatic locks.

08Premium Robotic Paint Finish

Our robotic paint booths, in a fully controlled environment, let us offer an unlimited choice of colours and an exclusive warranty against chipping, cracking and fading, thanks to UV/UVA/UVB protection on all our products.

09ENERGY STAR Certification

Our products exceed the ENERGY STAR standards in force in Québec.

10Québec Exclusivity

We don't sell hardware-store-grade windows. Fenestria runs its own production line with exclusive specs, manufactured in Amqui and Saint-Eustache. Superior-quality products you won't find anywhere else in Québec.
