uPVC Windows & Doors

Experience the pinnacle of energy efficiency and exquisite craftsmanship with our uPVC windows. Designed for passive house builds or retrofits, our windows offer exceptional thermal performance and long-term durability. We believe that your windows should be as unique as your project, which is why we provide a range of materials and designs to suit your needs.

What sets Passive House Windows apart?

They aren’t simply a specific type of window, but rather a performance-based standard. In general, these windows are characterized by being thermally broken, airtight, and triple-glazed with argon or krypton gas filling the gaps between the glass panes. They boast a low U-value (high R-value), maximizing solar gain and minimizing heat loss. The essence of passive design lies in achieving optimal energy efficiency without compromising comfort while maintaining excellent insulation. Any window with a Uw-value of 0.14 BTU/hr.ft2. ‘F or less (0.8 W/(m2K)) is suitable for a passive house. Additional factors such as overall energy use and air leakage contribute to achieving certified passive house standards. Depending on your climate, budget, and component availability, it is possible to choose windows with slightly higher values and compensate for any inefficiency elsewhere in your home if necessary.

Tailored solutions for diverse climates.

We understand that different regions have varying temperatures, altitudes, and humidity levels. Whether you’re situated in the mountains or by the sea, a passive house with superior thermal insulation will ensure consistent interior comfort. Our glazing options can be customized to maximize or minimize heat gain based on your specific climate. Hot climates may require reduced solar gain, while cold areas can benefit from maximizing it.

Unveiling the advantages of our products.

Achieving a Uw-factor of 0.8 or below narrows down the options to our uPVC windows with at least 6 chambers, or alternatively, vinyl windows with aluminum cladding. We emphasize that the Uw-value encompasses the entire window, including the glazing and frame, making the overall window crucial for energy efficiency and performance. Our cutting-edge Selenit75 line embodies all these advantages in one exceptional product.
