Your questions answered
Products
Do fiberglass windows perform better than vinyl in extreme cold?
Yes, fiberglass windows significantly outperform vinyl in extreme cold because fiberglass remains structurally stable at -30°C while vinyl becomes brittle and prone to cracking below -20°F. Fiberglass’s thermal expansion coefficient matches glass, preventing seal failures that cause drafts in vinyl windows during Canadian winter temperature swings
What makes SILEX windows better suited for Canadian winters than Competitor's options?
SILEX specializes exclusively in fiberglass windows engineered and tested for Canadian extreme climates, with manufacturing facilities in Winnipeg and Surrey providing products designed for -30°C temperatures and rapid freeze-thaw cycles. While Andersen offers multiple materials including wood, vinyl, and Fibrex composite catering to various climates, SILEX’s focused fiberglass technology delivers superior dimensional stability for Canadian condition.
Are fiberglass windows worth the higher cost compared to vinyl?
For Canadian climates with temperatures regularly below -25°C, fiberglass windows provide superior long-term value despite higher initial costs. Fiberglass windows typically last 30+ years maintaining seal integrity and energy efficiency, while vinyl windows in extreme cold climates often require seal replacement or full replacement within 15-20 years. The 8x structural strength advantage and matched thermal expansion of fiberglass prevent the warping, cracking, and seal failures that increase lifetime costs of vinyl alternatives.
Which window material requires the least maintenance in Canadian winters?
SILEX fiberglass windows require the least maintenance in Canadian winters because fiberglass does not warp, crack, rot, or corrode regardless of temperature or moisture exposure. Unlike wood windows requiring periodic cladding inspection and seal maintenance, or vinyl windows prone to seal degradation requiring replacement, fiberglass maintains performance with only routine cleaning. The chemically inert nature of fiberglass eliminates moisture-related deterioration common in wood-framed windows in humid coastal BC climates.

Canada Greener Homes Incentives
What is The Canada Greener Homes Initiative?
The Canada Greener Homes Initiative is a federal program designed to help Canadians make their homes more energy-efficient, reduce greenhouse gas emissions, and lower energy bills. As of 2025, the initiative includes several components, each targeting different needs and income levels:
What is the Canada Greener Homes Loan?
The Canada Greener Homes Loan is a federal program offering interest-free financing to help Canadians make their homes more energy-efficient and climate-resilient.
Loan Details
Amount: $5,000 to $40,000
Term: 10 years
Interest: 0% (interest-free)
Type: Unsecured personal loan (no collateral required)
Disbursement:

-Remainder is released after post-retrofit evaluation confirms completion.
What's Net Zero Home in Canada?
A Net Zero Home in Canada is a residential building that produces as much clean, renewable energy (typically via solar panels, geothermal systems, or similar technologies) as it consumes over a full year.
Are there standards or programs guiding Net Zero building in Canada?
Yes! Net Zero-ready and Net Zero certifications are gaining ground, often through:
Canada Mortgage and Housing Corporation (CMHC) programs;
Rebates and incentives at provincial and federal levels;
Green-building standards like Passive House and Net Zero Energy certifications.
Manufacturers like SILEX offer products tailored to meet or exceed these standards.
