Heat loss through patio doors

tlj7

We moved last year and have a south facing lounge with UPVC sliding patio doors that are 15 years old. They are in good condition so not keen to replace. However the room is very cold and is harder to heat up than our adjacent larger room that is north facing. We seem to be losing heat through the patio doors...

I appreciate the doors are old but could we replace the glass for better quality to help keep the heat in? If so any idea of cost? Or would this be a different thickness so not be possible?

Would appreciate any advice

Thank you.

Just ask a local glazing company, not one of the nationals.They will soon tell you if an upgrade is possible. You will not be under any obligation.

There is variety of low heat loss glass on the market (if they would fit into your existing frames * thickness) a glazier, window fitter could tell ? From experience we have had admittedly not with Patio doors but windows in office blocks it is possible but often only fractional less expensive than replacing entire window and frame and when consideration of the existing frames life span is taken into account not worth it? you can get “Reflective Window Films” basically stick on which suit a retro fit and is much cheaper

Yankee but gives most the info you’d require pro’s cons etc

You could always buy a decent set of curtains, you'll be surprised what a difference they make.

This.

Reseal the doors and put in a good set of thermal lined curtains and make sue they are drawn before dusk every day.

You an sometimes find old heavy curtains in charity shops.
Or you can make your own and interline them. Look at Merrick & Day for ideas, and fabricuk for fabrics.

I have patio doors installed new 3 years ago - they are wonderful. Rather than replace the glass - the seal will never be quite the same - I would get the curtains and save for good replacement doors.

Thank you for all your responses. I will look at the seals as didn't think about that. We have got curtains with bonded linings which does help but it is still not as warm as we would like. If new glazing is costly I think we may well need to save for replacing the doors; will contact a local glazier.
