Engineered to CSA A440S1 & ENERGY STAR Performance Targets

Our cold-climate aluminum systems are engineered to Canadian CSA A440S1 structural thresholds and ENERGY STAR thermal performance criteria, with test data and specimens for NRCan review.

Certification partnership

Cold-climate systems combine triple glazing, 34mm PA66 thermal breaks, warm-edge spacers, and thermal simulation data for CSA A440S1 and ENERGY STAR review. Certification listings are registered under the buyer’s company name.

5-Step CSA & ENERGY STAR Documentation Process

From cold-climate configuration review to Canadian certification documentation.

01

Requirements review

Review project climate zone, opening sizes, target standard, drawings, and local approval route.

Week 1
02

Test specimen production

Build full-size specimens to the nominated configuration, glazing, hardware, and performance target.

Week 2–4
03

Third-party laboratory testing

Coordinate the applicable accredited laboratory tests and record the performance data required for submission.

Week 5–8
04

Engineering document submission

Prepare calculations, drawings, installation details, declarations, and supporting test documentation.

Week 9–10
05

Local documentation issuance

Support the nominated local authority, notified body, or certification route through final documentation.

Week 11–12

Low-temperature operation, condensation resistance, thermal simulation, and installation details are reviewed for each Canadian project.

Can the systems operate in -40°C conditions?

The Canadian range is configured for cold-climate operation, with thermal simulations and project-specific glass, spacer, and hardware selection required for final approval.

What thermal break is used?

The reference configuration uses a 34mm PA66 thermal break with triple glazing and warm-edge spacers.

Can you support ENERGY STAR or NRCan review?

We can prepare thermal data, test specimens, calculations, and supporting documents for the nominated Canadian certification route.

How is condensation resistance addressed?

Frame, glazing, spacer, ventilation, and installation details are reviewed together rather than relying on a single nominal U-value.
