Reply To: Thermally broken uPVC window frames

[Jonny Parker]

Hi,

Great question.

uPVC joinery consists of a series of sealed air chambers in a lattice of uPVC. This offers a far greater thermal performance as it phases down the heat transmission using trapped compartmentalized air.

So its a very different design to a thermal break which is normally a single layer of uPVC sandwiched between aluminum joinery. (No air to phase down heat transmission)

Cheers

Jonny
