UPVC windows are highly durable, resistant to impacts, and maintain their structural integrity over time, providing a long-lasting solution for your home.
Made from recyclable materials and free of harmful chemicals like phthalates and BPA, UPVC windows are a safer choice for both your home and the environment.
With a less porous surface, UPVC windows require minimal upkeep, reducing the need for frequent cleaning and maintenance.
UPVC is known for its excellent thermal efficiency, helping to reduce energy costs by maintaining comfortable indoor temperatures year-round.
Choosing a professional installation company guarantees a precise and stress-free experience. Our expertise and dedication to quality has made us one of the top destinations in and around Toronto.
Our windows feature a sponge-like insect guard within the hollow, multi-chamber frames to prevent insects from nesting or entering through the window frame.
Neat+™ glass reduces dust with static dissipation and uses sunlight to break down pollutants, keeping windows naturally cleaner.
Our LoE coated glass meets Canada’s ENERGY STAR standards by balancing solar heat gain and insulation, reflecting infrared and UV light to maintain comfort and protect interiors.
With a low failure rate, our windows are backed by a 20-year warranty, providing unmatched protection against seal failure.
Our multi-chamber UPVC frames are designed to direct moisture away, minimizing condensation and preventing mold growth.
Engineered Thermal Insulation maximizes efficiency by using rigid insulation bars with dead air space, reducing heat and cold transfer through the window frame.
Our windows provide superior UV protection, reducing furniture fading, lowering heat gain, and helping cut down energy costs. Featuring a U-Factor of 1.4 W/m²K and an Energy Rating (ER) of 29+, they meet and exceed efficiency standards.
Advanced multi-chamber frames and specialized glazing reduce exterior noise, creating a quieter indoor environment.
Made from high-quality uPVC, our windows resist impact, warping, and cracking, ensuring long-lasting performance.
Our vinyl windows are 100% recyclable, free from harmful phthalates and BPA, making them an environmentally responsible choice.
