What U-value does 36mm triple glazing achieve?

With warm edge spacers and premium Low-E coatings, 36mm triple glazing typically achieves U-values between 0.6-0.8 W/m²K, depending on glass specification and gas fill type.

Can I specify krypton gas instead of argon?

Yes, krypton gas can be specified for even better thermal performance, though argon gas remains the standard fill offering excellent value and performance in 16mm cavities.

How does 36mm compare to 28mm triple glazing?

36mm units provide superior thermal performance due to wider gas cavities, but require deeper window frames. 28mm units suit standard frames whilst 36mm suits new builds and deep rebates.

What's the maximum size for made to measure 36mm units?

Maximum dimensions depend on glass specification, but typically reach 2000mm x 3000mm. Contact us with your exact requirements for size feasibility and structural glazing recommendations.

About 36mm Triple Glazing

36mm triple glazing represents the pinnacle of domestic glazing performance, featuring three panes of glass with generous 16mm gas-filled cavities. This configuration maximises the insulating properties of argon gas whilst accommodating Low-E coatings on multiple surfaces for superior energy retention.

These sealed units achieve exceptional U-values as low as 0.6 W/m²K when specified with warm edge spacer bars and premium Low-E coating systems. The wider gas cavities reduce convection currents, whilst BS EN 1279 certification ensures long-term reliability and thermal performance in demanding applications.

Pane Relief manufactures all 36mm triple glazed units to your exact measurements, backed by our comprehensive quality guarantee. Each made to measure sealed unit is precision-manufactured and delivered nationwide throughout the UK.
