Sealed double glazing units

Catbells

I'm going to refurbish my old front door which is very old and good hardwood quality. A new door is too expensive for me.   I need to buy some sealed double glazed units to fit into 5 small window spaces.  Does anyone know where I can buy these.  I have someone to fit them and also insulation trims from Stormguard.  Thanks.

What glass do you have in your door? Are you sure it can be replaced with a sealed unit that is much thicker than normal glass?

Replacing small single glazed units in a door with double glazed is unlikely to be worth the cost and effort.  If you want to do it, find a local glazing company to get them made.

It is possible to get some very thin sealed units - Depending on size, 12mm or even 10mm thick. Thermal performance is better than a single sheet of glass, but not in the same league as a modern low E DG sealed unit filled with argon.

Not going to save a huge amount on heating costs from just upgrading the glass - A thick thermal curtain would be more effective.

Thanks.  I want double glazed units for insulation.  Here's a picture.

Thank you.  Are glaziers still around?  We had one nearby once but long gone.  North London/Herts area.

FreeBear I currently have a long lined curtain too.

We recently purchased sealed DG units for a large DIY project  from sealed units online and were pleased with the service, quality and price.

I think this can be done. I'd reserve at least 15mm for beading on each side.

Subtract 30mm from the door thickness to see the maximum acceptable thickness of the sealed units.
