Vinyl Windows
Our vinyl windows use 100% uPVC extrusions with patented formulas ensuring durability against cracking, warping, or fading. These low-maintenance windows feature insulated glass units with low-emissivity coatings and argon gas for enhanced energy efficiency. Available in single/double hung, slider, casement, and specialty configurations, they meet Canadian climate demands while offering customizable colors and shapes.
Energy-Efficient Doors
We manufacture doors using materials like steel, fiberglass, and vinyl that withstand harsh weather while maintaining thermal performance. Options include entry doors with security features, patio doors with multi-point locking systems, and garage doors with insulation ratings suitable for Canadian climates. All products combine energy savings with aesthetic customization through various finishes and glass designs.
Custom Window Replacement
Our replacement windows address aging wood or vinyl units with modern, maintenance-free alternatives. The process includes precise measurements for brick-to-brick fitting, selection from multiple glass privacy levels, and color-matching options. Customers benefit from improved energy efficiency, increased property value, and enhanced curb appeal through contemporary designs and unobstructed views.
Bay/Bow Windows
These projecting windows create focal points while maximizing natural light. Bay configurations feature three lites with a large fixed center, while bow windows use four to five lites for curved appearances. Both options use durable vinyl frames and insulated glass units, available in custom shapes and sizes to complement modern or traditional architecture.
Fiberglass Doors
Our fiberglass entry doors resist warping, cracking, and rotting better than traditional wood. They feature insulated cores for thermal efficiency and come with customizable glass inserts, sidelites, and transoms. The surface accepts paint or stain finishes while maintaining low maintenance requirements, making them ideal for Kitchener's climate conditions and architectural diversity.
