Is there such a thing as "Thermal Glass" for singl

[Craig]

I know of Pilkington K, but this is designed to be used for double glazed units. Can you increase the thermal performance of single glazed units by using different glass (in addition to curtains, seals, etc - these windows are new so can also look at the glass options)?

Many thanks for all suggestions!

Hmm - just checked and Pilkington say you can use their K Glass in a single glazed application. Better than nowt...

You can also add window film with a low emissivity coating to existing windows.
