Keylite Lacquered Pine 780x 980 Top Hung Roof Window Triple Glazed

Keylite Lacquered Pine 780x 980 Top Hung Roof Window Triple Glazed

Keylite's Top Hung Roof Windows are designed with safety in mind, opening outward to 45° to comply with statutory regulations. This makes them ideal as a means of escape in case of an emergency. These windows are especially suited for low-pitch roofs, as the outward-opening design maximises daylight without the sash encroaching on the room’s interior space. For those requiring assistance with specifications, Keylite's technical team is available to offer support. Please note, however, that sizes 02 (550 x 980) and 03B (660 x 980) only open to 30°, and as such, they cannot be classified as means of escape.

Keylite’s standard Pine Finish enhances the natural beauty of the wood with a clear, satin lacquer that is applied in multiple coats. This finish offers a traditional aesthetic, perfect for complementing timber features in interiors. The Pine Finish is not only practical but also hard-wearing, making it suitable for most interior spaces. In addition, Keylite offers a 10-year guarantee on these windows, ensuring long-term durability and reliability.

The Top Hung Roof Windows come equipped with several key features. As a means of escape (excluding sizes 02 and 03B), the window opens to provide an unobstructed area for a safe exit. The opening handle is conveniently located at the bottom of the window. The multi-stop opening function allows the window to remain open at any position between 0-45°, giving users maximum flexibility. Ventilation is effectively managed through a vent flap located at the top of the roof window, allowing airflow even when the window is closed. Keylite’s unique thermal features, including an Expanding Thermal Collar, Warm Edge Glazing, and a streamlined fit, enhance the overall thermal performance of these windows.

The Triple (KTG) glazing unit features a 4mm toughened outer pane, followed by a 10mm Krypton gas-filled cavity, a 4mm inner pane, and an additional 8mm Krypton gas-filled cavity with another 4mm inner pane. This triple glazing design provides enhanced energy efficiency with a lower U-value, contributing to better thermal insulation. The unit also includes warm edge glazing for further improved performance.

The Triple (KTG) glazing achieves a U-value of 0.6 Ug W/(m².K), an Rw rating of 32 dB for sound reduction, a g-value of 55%, a visible light transmittance (Tv) of 74%, and a UV transmittance (Tuv) of 31%.
