UV Rated Windows

UV rated windows are important for protecting indoor furnishings and reducing the risk of skin damage from UV radiation. They are also useful for reducing energy costs by blocking solar heat gain, which can help to keep a building cooler in the summer months. When selecting UV rated windows, it is important to consider factors such as the level of UV protection, energy efficiency, and cost to ensure that the windows meet your needs and preferences.

Save on Energy

In Canada, it is recommended to aim for a U-factor of 1.4 W/m2K or lower for windows and doors. ER is an alternative rating, and it includes the solar gain effect of the window. The higher the ER, the more energy efficient the window. Good performing windows and doors have an ER of 29 or higher.

    UPVC Windows Benefits

    Welda UPVC Vinyl Windows Benefits

     

    kitchen window Welda

    UPVC refers to unplasticized polyvinyl chloride. As the name suggests, it does not contain phthalates or BPA, and hence is a safe product for the environment while still maintaining the benefits of a vinyl window frame. UPVC is a robust material, widely used in the manufacturing of windows due to its thermal efficiency and durability.

    UPVC offers several additional benefits:

    • High Durability and Longevity
    • Environmentally Friendly: Recyclable, No Phthalates or BPA
    • Less porous surface significantly reduces maintenance
    • High energy efficiency
    • Increased lifespan to last decades
    • Rigid and does not flex
    • High impact resistance
    • Bright white frame and will maintain its color over time
    • Recyclable material

    u-PVC (unplasticised) is hard and rigid with an ultimate tensile stress of approximately 52 MPa at 20°C and is resistant to most chemicals. Generally PVC-U can be used at temperatures up to 60°C, although the actual temperature limit is dependent on stress and environmental conditions.

    Our selection of UPVC windows are available in a classic white frame, with additional colour foils available upon request. Add mullions or Georgian bars for a traditional design.

    LoE Coated Glass

    A New Coating for Cold Canadian Weather

     

    Manufacturers need flexible choices when designing windows to beat the Canada ENERGY STAR® 2020 code. So we now offer a new option for the Canadian residential market. It is called LoĒ-Di89™, a new application of our LoĒ-i89™ coating. LoĒ-Di89 glass gives manufacturers that extra nudge over LoĒ-180ESC™ to meet Canada code compliance.

    LoE Coated Glass

    Enhanced Compliance for all of Canada For Canada, ENERGY STAR version 5.0 went into effect on January 1, 2020. These new requirements mean that windows and doors now must meet a minimum Energy Rating (ER) of 34. To meet that condition, dual pane units need to balance a high solar heat gain coefficient (SHGC) with a low U-Factor. Specific coatings reflect infrared light, keeping heat inside in winter and outside in summer. They also reflect damaging ultraviolet light, which helps protect interior furnishings from fading.

    Super Spacer Technology

    Super Spacer Technology

     

    Inside quality built windows you will find a spacer between the layers of glass. Our innovative 100% polymer foam spacer outperforms other spacers in the industry’s toughest tests with a simulated 90-year lifespan.

    New Generation of Insulation System

    Our incredibly low failure rate means that warranty repairs for seal failure are a rare event. But in the case of failure, we’ll back you up unlike any other glass company. Your IG investment is guaranteed for 20 years, with up to a 150% credit warranty. There is simply no other company willing to match that level of risk.

    Easy Clean Glass - Neat+™

    Neat+™ Glass. A New Generation, Available Now.

    Neat+ Glass is the latest generation of lower maintenance glass. With Neat+, glass is naturally cleaner. Since 2006, more than 57 million windows with Neat glass have been sold, serving as the leading product for low maintenance glass.

    Easy Clean Glass

    Neat+ uses a combination of static dissipation to reduce the amount of dust on the window’s surface, along with help from the sun to break down greenhouse gases and other pollutants to keep the window naturally cleaner.

    ETI Insulation®

    ETI Insulation®

     

    EV insulation

    Engineered Thermal Insulation uses engineered rigid insulation bars with dead air space to maximize thermal insulation by reducing heat and cold transfer through the window frame.

    BENEFITS
    1 Maximizes insulation using otherwise unused cavities
    2 Environmentally friendly
    3 Reduces annual energy costs
    4 Improves the window’s Energy Rating by 3 ER points

    Insect Guard Fly Maze

    Insect Guard Fly Maze

    As a standard practice, our windows have a sponge-like insect guard inside our hollow multi-chamber frames. This prevents insects from nesting or entering through a window frame.

    Fusion Welded Sash & Frame

    Fusion Welded Sash & Frame

    Each sash and frame is precision-mitered, then fusion welded using extreme heat and pressure. This ensures a virtually inseparable bond at every joint.

    Lead-Free MultiChamber UPVC Frame

    Lead-Free MultiChamber UPVC Frame

    Designed to draw moisture away from the window to the drains, reducing condensation and the formation of mould.

    Triple Weather Seals

    Triple Weather Seals

    These seals are oversized for higher performance and built into the frame to prevent any air transfer, allowing for a completely sealed unit.

    Solar Bond Paint

    Solar Bond Paint

    There are thirteen standard window colours for you to choose from. We can also custom colour match your windows, so they co-ordinate with any existing outdoor decor finishes.
