What U-value can I expect from triple glazed windows?

Triple glazed units typically achieve U-values between 0.6-1.0 W/m²K depending on glass specification, spacer type and gas fill. Premium configurations with krypton gas can reach 0.6 W/m²K.

What's the standard thickness for triple glazed sealed units?

Standard triple glazed units range from 28mm to 44mm overall thickness. Common configurations include 4-12-4-12-4mm (28mm) and 4-16-4-16-4mm (36mm) with argon gas fill and Low-E coating.

Are triple glazed windows worth the extra cost over double glazing?

Triple glazing offers 30-50% better thermal performance than standard double glazing, plus superior noise reduction. Most beneficial in exposed locations or when replacing single glazing.

Can you manufacture triple glazed units for existing window frames?

Yes, we supply made to measure replacement sealed units for existing triple glazed frames. Simply provide accurate measurements and we'll manufacture units to match your frame specifications.
