Triple Glazing

Triple-glazed systems deliver superior insulation and internal warmth compared to standard double glazing. Our brand partners, Internorm, Rationel, QFORT, Velfac, and Solarlux specialise in high-performance triple-glazed units that offer excellent airtightness, weather resistance, and long-term stability. These solutions are ideal for homes seeking the highest levels of energy performance without compromising on design.

Beyond the measurable energy savings, triple-glazed systems provide a consistent, comfortable internal environment, eliminating the cold spots often associated with older windows. By incorporating three panes of glass with two insulated cavities, triple glazing significantly reduces heat loss, improves internal surface temperatures and enhances overall building comfort.

Anglezarke’s partnerships with industry-leading manufacturers, such as Internorm, Rationel, and QFORT, ensure that our triple glazing meets the rigorous demands of modern architecture, offering exceptional light transmission and slim sightlines despite the increased complexity of the unit.

We offer a comprehensive range of triple-glazed products, including windows, large-scale sliding doors, and bespoke architectural glazing systems. Available in various materials, from high-strength aluminium to warm timber-aluminium composites, our triple glazing is tailored to your project’s specific aesthetic and performance requirements.

Thermal Efficiency

Thermal efficiency is critical for modern architecture and must be considered as part of the complete building envelope, not simply at the product level. It offers substantial benefits beyond mere temperature regulation. By incorporating advanced thermal breaks and high-performance glazing, Anglezarke UK’s systems dramatically reduce reliance on artificial heating and cooling.

Passive Housing

Anglezarke UK specialises in supplying and installing high-performance windows, doors, and architectural glazing systems designed to meet the stringent standards required for certified Passive House buildings. We work in partnership with leading manufacturers, including Internorm and Reynaers Aluminium, to deliver precision-engineered solutions offering exceptional airtightness, low U-values, and consistent thermal performance throughout the year.

What is triple glazing?
Home Owner Information

Triple glazing uses three panes of glass separated by two gas-filled spacers, typically argon or krypton. These cavities act as insulating layers, while low-emissivity (Low-E) coatings reflect heat back into the room. The result is significantly improved thermal performance and enhanced sound insulation compared to standard double glazing.

How does triple glazing save energy?
Home Owner Information

The additional pane and gas layer drastically reduce the window’s U-value, often achieving figures around 0.6 W/m²K or lower depending on system specification. This means less heat escapes your home in winter and less heat enters in summer, lowering your reliance on heating systems and reducing energy bills.

Is triple glazing worth the extra cost?
Home Owner Information

While triple glazing has a higher initial cost than double glazing, the investment is often offset by substantial long-term savings on energy bills. Furthermore, it provides superior thermal comfort, reduces noise pollution, and contributes to a higher BREEAM or Passivhaus rating for the property.
