Triple glazing plays an important role in achieving high levels of energy efficiency in residential buildings.
For homeowners planning a Passive House or low-energy property, high-performance windows help limit heat loss and support a well-insulated, airtight building envelope.
Our Internorm range includes window systems suitable for Passive House applications, with selected specifications offering particularly low U-values and excellent thermal insulation.
A U-value measures how much heat passes through a building component. The lower the U-value, the better its insulating performance.

The cost of triple glazing depends on several factors, including the size and number of windows, frame material, glazing specification, design and installation requirements.
For example, timber-aluminium windows may have different pricing considerations from uPVC-aluminium systems, while larger glazing configurations or bespoke finishes can also influence the final cost.

Triple glazing can be a worthwhile investment for homeowners looking to improve thermal insulation, reduce heat loss and increase comfort. It is particularly suited to energy-efficient new builds, major renovations and Passive House projects.
Triple glazing can provide improved thermal insulation compared with double glazing, although performance depends on the complete window specification, including the glass, frame and installation quality.
By reducing heat loss through windows, high-performance triple glazing can help lower a home's heating demand. Actual savings depend on the property's existing windows, insulation, heating system and energy usage.
U-values vary depending on the window system and specification. Selected Internorm triple glazed windows can achieve very low U-values, making them suitable for energy-efficient and Passive House applications.
Triple glazing can be installed in many existing homes as part of a window replacement or renovation project. Suitability depends on the property's structure, installation requirements and chosen window system.
