Multi-chamber vinyl frames pair with an 11/16″ insulated glass unit featuring Low-E coating, Argon fill, and “S” Class Super Spacer®. This combo locks in heat during deep-freeze nights and rejects excess solar gain during chinooks, trimming your utility bills year-round.
The hollow chambers act as built-in thermal breaks, slowing heat flow so your basement stays comfortable without cranking the space heater. Low-E glass bounces furnace warmth back inside when it’s –25 °C, yet reflects up to 70 % of high-altitude UV when a January chinook spikes to +10 °C. Dense argon gas reduces convection inside the unit, and the warm-edge spacer slashes edge-of-glass condensation—protecting wood sill plates from mould and rot.
Die-cast cam locks and a closed-back keeper reinforce the interlock, while 3 ¼″-deep uPVC profiles shrug off warping, hail impact, and forced-entry attempts — ideal for ground-level windows.
Solid-zinc hardware meets or exceeds CAN/CSA A440 forced-entry requirements, giving you peace of mind for basement bedrooms and rental suites. The thick-wall vinyl is UV-stabilised and impact-tested to withstand prairie hailstones, so it won’t crack the first time marble-sized ice hits. Internal metal stiffeners can be added for extra span strength in wide sliders, keeping frames straight and seals tight over decades of freeze–thaw stress.
Triple-seal weather-stripping compresses tight to block prairie dust, wind gusts, and driving rain. Built-in drainage channels whisk melt-water away from your foundation.
A soft inner bulb seal cushions the sash and filters fine debris, a fin-seal brushes away grit each time you slide the window, and a rigid outer gasket deflects wind-blown water. Hidden weep paths route any water to the exterior face, preventing pooling in the sill pocket and keeping insulation batts dry. The harder a chinook wind blows, the tighter the seals press—so your basement stays cosy, quiet, and moisture-free.
Operable sashes lift out completely for ground-level cleaning, then glide on a Euroglide rail for smooth, finger-tip opening — no ladders or awkward reaches.
Pop the sash inward, lift it clear of the frame, and wash both sides from a standing position in the mechanical room. Nylon rollers on brass axles ride a stainless sill rail that resists the calcium-chloride salts common on Calgary sidewalks, so the glide stays silent and effortless after thousands of cycles. Low-profile pull rails won’t snag window wells or security grilles, maximising clear-opening size for code-compliant egress.
Multiple frame depths and custom sizing let us match existing wall thicknesses or create a code-compliant egress cut-out without bulky add-ons, ensuring a seamless look inside and out.
Choose a slim 3 ¼″ retrofit frame to slip into 1950s concrete openings, or opt for a 4 ⅝″ new-construction profile that aligns with 2 × 6 basement pony walls. We laser-measure every opening and can add a 45° “egress bevel” to maximise clear-opening area, meeting Alberta Building Code escape requirements without enlarging the well. Interior jamb extensions and exterior brickmoulds are colour-matched at the factory, eliminating site-paint touch-ups and speeding installation.
