Product Information
Introducing the Keylite White PVC Top Hung Roof Window Hi-Therm, a seamless fusion of safety, functionality, and elegance tailored for contemporary living spaces. This window is designed to meet statutory safety regulations, offering an easy escape route in emergencies. Its top-hung design is perfect for low-pitch roofs, opening outward to allow an abundance of natural light to flood your space without encroaching on your interior. Even when securely locked, the window provides trickle ventilation, ensuring a continuous flow of fresh air while keeping insects at bay with its built-in filter.
The installation process is simplified with Keylite's innovative Integrated Thermal Collar. By simply pulling the tapes, the foam expands to fill the gap between the window and roof timbers, making the installation quick and efficient, from box to roof in just two minutes. The white PVC profile is not only visually appealing but also highly moisture-resistant, making it a maintenance-free solution suitable for any room, including kitchens and bathrooms. Opt for the Polar finish to achieve a bright, white, and hassle-free aesthetic that complements any home decor.
This roof window is crafted with precision, featuring Hi-Therm glazing with clear glass for optimal thermal performance and clarity. Its manual operation ensures ease of use, while the robust construction promises durability. Backed by a 20-year guarantee, provided it is serviced by a Keylite engineer within its ninth year, this window is a smart investment in your home's safety, comfort, and style. Choose the Keylite White PVC Top Hung Roof Window Hi-Therm for a reliable, stylish, and efficient addition to your living space.
