Passive House Double Glazing

Passivhaus certifiedUltra-low U-values

Some Passive House projects specify double glazed units for south-facing positions to maximise solar gain while still meeting overall energy targets. Our Passive House double glazed units balance thermal retention with solar transmittance for optimal whole-building performance.

About Passive House Double Glazing

Passive house double glazing represents the pinnacle of energy efficient glazing technology, featuring advanced sealed units with specialised Low-E coatings and argon gas fills. These high-performance units typically utilise 4mm low-iron glass with enhanced coatings to maximise thermal efficiency while maintaining excellent light transmission.

Achieving U-values as low as 1.0 W/m²K, our Passivhaus-certified double glazed units incorporate warm edge spacer bars and premium gas fills to deliver exceptional thermal performance. Manufactured to BS EN 1279 standards, these energy efficient sealed units significantly reduce heat loss whilst meeting the stringent requirements for passive house certification.

Pane Relief supplies made to measure passive house double glazing throughout the UK, backed by comprehensive quality guarantees. Our precision manufacturing ensures each sealed unit meets exact project specifications for your passive house build.

Frequently Asked Questions

  • What U-value can passive house double glazing achieve?
    Our passive house double glazing achieves U-values as low as 1.0 W/m²K, comfortably meeting Passivhaus Institute requirements for ultra-low energy buildings and passive house certification standards.
  • What glass thickness is recommended for Passivhaus projects?
    We typically recommend 4mm low-iron glass with enhanced Low-E coatings and 16mm argon-filled cavities, providing optimal thermal performance whilst maintaining structural integrity for passive house applications.
  • How does passive house glazing compare to standard double glazing?
    Passive house glazing delivers approximately 50% better thermal performance than standard double glazing, utilising advanced coatings, warm edge spacers, and gas fills to achieve ultra-low U-values.
  • Can you supply made to measure units for self-build projects?
    Yes, we manufacture made to measure passive house double glazing for self-builders and contractors throughout the UK, with full technical support and delivery to site.
