What glass configuration is used in 28mm triple glazing?

Typically 4mm-6mm-4mm-6mm-4mm with two 6mm cavities, though variations like 4mm-5mm-4mm-5mm-4mm are available depending on specific thermal performance requirements and frame compatibility.

What U-value can I expect from 28mm triple glazing?

Standard 28mm triple glazed units with Low-E coating and argon gas achieve U-values between 0.8-1.0 W/m²K, representing a significant improvement over typical double glazing at 2.8 W/m²K.

Will 28mm triple glazing fit my existing double-glazed frames?

Yes, 28mm triple glazing is specifically designed to retrofit most standard double-glazing frames, though we recommend checking your glazing rebate depth and providing exact measurements for compatibility confirmation.
