What Makes Aluplast Window Systems Different From Standard Vinyl Windows?
Aluplast windows distinguish themselves through their sophisticated chamber architecture. While standard vinyl windows typically feature 3-5 chambers, Aluplast profiles incorporate 5-7 chambers within their frame design. This increased compartmentalization creates multiple thermal barriers that significantly reduce heat transfer.
The profile depth represents another critical difference. Standard North American vinyl windows measure 2.5-3 inches (63-76mm) in depth, whereas Aluplast systems range from 70-85mm. This additional depth accommodates thicker glazing units and provides better acoustic insulation. For Canadian homeowners dealing with temperature extremes, this translates to measurable improvements in energy-efficient windows performance.
“The multi-chamber design in premium European profiles creates distinct thermal zones that standard vinyl simply cannot replicate. When properly installed with quality glazing, these systems can reduce heating costs by 15-20% compared to older windows.” — Vitaly Shapiro, Vice President of Sales

How Do Aluplast Windows Address Noise Reduction Requirements?
Acoustic performance matters for urban homeowners and properties near busy roads. Aluplast’s multi-chamber design inherently provides better sound dampening than single-chamber profiles. However, glazing selection determines overall acoustic rating.
Laminated glass significantly improves window sound insulation compared to standard annealed glass. The plastic interlayer between glass panes dampens vibration, reducing sound transmission. For maximum noise reduction, asymmetric glazing configurations—using different glass thicknesses in each pane—prevent resonance frequencies from passing through.
The Sound Transmission Class (STC) rating quantifies acoustic performance. Standard double-glazed Aluplast windows achieve STC ratings of 32-35, while optimized configurations with laminated glass reach STC 38-42. For reference, an STC rating of 35 reduces normal conversation to a faint murmur.
What Maintenance Requirements Do Aluplast Windows Have?
uPVC windows require minimal maintenance compared to wood or aluminum windows. The material doesn’t require painting, staining, or sealing. However, regular cleaning and hardware maintenance extend service life and maintain appearance.
Recommended Maintenance Schedule
- Clean frames and glass quarterly using mild soap solution and soft cloth
- Lubricate hardware moving parts annually with silicone-based lubricant
- Inspect weatherstripping and gaskets for damage or compression every two years
- Check drainage holes in sill for blockage during spring and fall
- Verify proper operation and adjust hardware if resistance develops
Avoid abrasive cleaners or solvents that damage uPVC surfaces. The material’s color is integrated throughout, so minor scratches don’t expose different-colored substrate. However, harsh chemicals can cause surface discoloration or degradation.
How Do Aluplast Windows Fit Into Canadian Building Codes and Standards?
Canadian building codes establish minimum performance requirements for fenestration products. Aluplast windows, when properly certified, meet or exceed these standards. However, importers must ensure products carry appropriate certifications for the Canadian market.
The National Building Code of Canada references CSA A440 series standards for windows. Products must demonstrate compliance through testing at accredited laboratories. Additionally, ENERGY STAR™ certification provides a recognized benchmark for energy performance across different Canadian climate zones.
For the Greater Toronto Area (Zone 2 in ENERGY STAR™ ratings), windows must achieve maximum U-values of 1.40 (imperial units) or approximately 0.25 W/(m²·K) (metric units). Aluplast’s premium configurations easily meet this threshold, qualifying homeowners for potential rebates through provincial efficiency programs. Information about available incentives appears on the window rebate Ontario page.
What Color and Finish Options Are Available for Aluplast Windows?
Aesthetic flexibility allows Aluplast windows to complement various architectural styles. The base uPVC comes in white, cream, and several grey tones as solid-color options.
