Fusion-welded corners on every frame create a single, rigid shell that won’t twist or separate, even after decades of freeze–thaw cycles. Available frame depths of 3 ¼″ and 4 ⅝″ ensure a perfect match to new-build or retrofit wall thicknesses.
Because the vinyl is heat-melted into one piece, there are no mechanical screws to work loose when a –25 °C morning rockets to +10 °C under a Chinook. That monolithic strength keeps jambs perfectly square, so sashes slide smoothly and fixed lites stay airtight year after year. The deeper 4 ⅝″ profile aligns with modern 2 × 6 constructions, creating a flush drywall return and eliminating extra jamb extensions—while the slimmer 3 ¼″ retrofit frame slides neatly into older bungalow openings without disturbing brick-moulds.
A premium black “S”-Class Super Spacer® pairs with full 7/8″ Low-E/Argon insulating glass (1 ⅜″ triple glazing optional) to slash heat loss and minimise condensation — critical for Calgary’s wide temperature swings.
The warm-edge spacer blocks conductive heat flow at the glass edge, so you don’t wake up to icy puddles on the sill after a –30 °C night. Low-E coatings bounce furnace heat back inside in winter and reflect 70 % of high-altitude UV in summer, stabilising room temperatures without heavy drapes. Dense argon gas slows convection inside the unit, trimming energy bills, while an optional triple-pane package pushes U-values into Net-Zero territory for homeowners chasing Canada Greener Homes rebates.
A factory-applied tape-glazing system plus a co-extruded flexible exterior seal block air and water infiltration, preserving structural integrity and keeping interiors dry during driving rain or melting Chinook snow.
Unlike site-applied silicone that can pull away as vinyl expands and contracts, the high-tack glazing tape bonds the IGU to the sash on all four sides—eliminating voids where moisture can pool and freeze. The outer gasket flexes with temperature changes instead of cracking, so spring hail or pressure-washing won’t compromise the seal. Together they deliver CSA-certified performance for water penetration, giving you peace of mind when Calgary’s sudden thunderstorms dump a month’s rain in an hour.
Hidden exterior drainage channels remove water without the need for visible weep-hole covers, while slim main-frame profiles align perfectly with our other vertical and horizontal sliders for a unified curb-side look.
Concealed weeps funnel melt-water to the outside face, preventing staining on masonry and keeping insects from nesting in open ports. Narrow sight-lines mean bigger glass areas, so basements and bonus rooms feel brighter even during short winter days. Because profile dimensions match our casement and picture window lines, whole-house renovations maintain consistent reveals and shadow lines—boosting resale value with architectural cohesion instead of a patchwork appearance.
Smooth-glide rollers and balance systems are engineered for thousands of cycles, and all tilt latches are tucked away to prevent snagging curtains — less fuss, more usable daylight.
Sealed brass-axle rollers shrug off prairie dust and salted slush, so sashes keep gliding with fingertip force after years of use—no annual silicone spray required. Constant-force coil balances are rated for 20 000 lifts and housed in a protective casing that won’t seize when condensation freezes. Recessed tilt latches let you pop the sash inward for easy cleaning, yet stay out of sight so blinds sit flush, maximising natural light and preserving the window’s minimalist aesthetic.
