Window Force windows feature a dual-seal spacer system specifically designed to reduce heat transfer at the glass edges and minimize condensation. This warm-edge technology improves overall thermal performance and helps prevent seal failure over time, contributing to the longevity and efficiency of your windows.

The warranty coverage structure is: 100% coverage for the first 25 years, 80% manufacturer / 20% customer from years 25-30, and 25% manufacturer / 75% customer after 30 years.
Yes, we install windows throughout the year, including during winter months. Our experienced installation teams in Toronto are equipped to handle installations in all weather conditions while ensuring proper sealing and performance. We take precautions to minimize heat loss in your home during the installation process.
Condensation occurs when warm, humid indoor air contacts a cooler surface, like window glass, and releases moisture. Windows don't cause condensation; they simply reveal excess humidity in your home. However, high-quality vinyl windows with warm-edge spacer technology and proper Low-E glazing keep the interior glass surface warmer, significantly reducing the likelihood of condensation forming. Maintaining indoor humidity between 30-50% also helps prevent this issue. Rule of thumb: to prevent window condensation during the heating season, the recommended indoor RH is 30 per cent to 50 per cent. When it is below - 10°C (14°F) outdoors, the recommended indoor RH is 30 per cent..
Vinyl windows require minimal maintenance. Clean the glass and frames periodically with mild soap and water. Make sure to avoid abrasive cleaners that could damage surfaces. Wipe down sliding tracks to ensure smooth operation, and lubricate hardware components as needed. Inspect weatherstripping annually and ensure weep holes remain clear of debris. With basic care, your windows will maintain their appearance and performance for decades.
Window Force windows are CSA certified for quality and safety, and engineered to meet or exceed ENERGY STAR® standards for energy efficiency. As an ENERGY STAR Partner, we're committed to manufacturing products that deliver superior thermal performance and help reduce energy consumption across all Canadian climate zones.
Not necessarily. Different window orientations benefit from different glazing configurations. South and west-facing windows may benefit from Low-E coatings that optimize solar heat gain in winter while blocking excess heat in summer. North-facing windows prioritize insulation over solar gain. Our team can recommend the ideal glass configuration for each opening to maximize energy efficiency throughout your home.
Production and delivery typically take several weeks, depending on order size, customization requirements, and current production schedules. We manufacture all windows to order at our Toronto facility, ensuring precision and quality. Your specific timeline will be confirmed during the ordering process, and we'll keep you updated throughout production.
Window Force is primarily a Toronto manufacturer and supplier, serving builders, dealers, and contractors across Ontario and North America. However, we can also provide professional installation services for projects in our service areas. Whether you need supply-only or full installation support, contact our team to discuss the best approach for your project.
New construction windows are designed for installation in newly built homes or additions where the wall framing is exposed. They have an option of a nailing fin (flange) that attaches directly to the wall studs before exterior cladding is applied. Replacement windows, on the other hand, are custom-built to fit into existing window openings without disturbing the surrounding interior or exterior trim. They install directly into the current frame opening, making them ideal for upgrading older windows in occupied homes. Window Force manufactures windows suitable for both applications. Our team can help determine which approach is right for your project based on whether you're building new or replacing existing windows.
