What benefits will Passivhaus Windows & Doors Provide?

Many homeowners and self-builders are striving to create low energy and well-insulted homes that provides ultimate comfort and reduces energy costs. There are many design and construction factors included as to how you can achieve this but a good starting point is your glazing.

This will be the main impact on reaching a Passivhaus standard, as opposed to investing in renewable energy first. Because of this, we would recommend choosing triple glazing options.

Our selection of windows and doors will provide:

  • Enhanced insulation and thermal efficiency
  • High sound insulation.
  • A choice of materials. In some cases, this includes dual or cladded options.
  • Increased solar energy entering the building
  • Solar shading that prevents your home from overheating.
  • U-Values lower than 0.62 W/m2K (Passivhaus recommends a U-value below 0.8. Standard Building Regs allow up to 2.0 W/m2K.)
  • Technology to future-proof your home.

    What Do Our Customers Say?

    Absolutely fantastic service from start to finish. Nothing was to much trouble. The windows and doors have been fitted with utmost care and attention. Even in the snow and cold. The fitters are polite and very tidy. Colin, Jamie and team thank you so much. Would highly recommend.

    Marie Crossley

    Excellent and prompt service from Infinite Windows & Doors when we opted to use them to provide our bifold doors. The builder who is building our extension failed to sort them through his "usual" window company so we cast out on our own and found Infinite. I'm very glad we did. The doors arrived earlier than expected, and were fitted in the course of an afternoon. They look fabulous and will look even better when the rest of the extension build is completed!

    Stella-Maria Thomas

    Excellent showroom for the Internorm windows. Really helpful people too.

    Grant Osborne
