Single glazed heat loss

[chirpychippy]

A question if I may?

We have a conservatory on the back of our bungalow that needs demolishing, but we have other works to start and complete before this can be done.

Between the ice cold conservatory and our kitchen are two single glazed sliding doors, which have the thermal efficiency of a sieve.

I'm wondering if I screw perspex over the external side of the doors will it help keep the cold out by forming a thermal void between the glass and the perspex?

Thank you.

Might help a bit. Doubt it can be measured. Sometimes you can pick up unused perspex sheets off Marketplace.

Replacing blinds with heavy curtains would help.

Yes it will. Whether it'll lower your heating bills to the point where it pays you back the cost of a Perspex sheet before the whole thing is demolished (is the door going?) depends on how much you end up paying for Perspex

You can do it on the inside too, for two pockets of trapped air

it won't hurt. the more still air you can put between inside and outside the better.

It's also worth checking that the draught proofing is absolutely as good as you can get it...

Find a local foam supplier and make a plug.
They will cut sponge foam to fit and push in.

If you don't want to walk through then just buy 1200mm x 2400mm polystyrene sheet from DIY store and cut to size and shove in

Once the conservatory is going to be removed I intend to put upvc doors in in there place, but that is straight forwards either.

For now it's just trying to reduce the cold air ingress. I'm not concerned about off setting the perspex cost against any heating cost.

I'll probably put the perspex cost through my business

The doors are used daily, they are access to the back garden,but thank you.

Ok.

Get and find a set of doors preferably free and hang.
eBay.gumtree ect. Second hand set.
Hang this side and put draft excluder around.
I've done similar but single doors leading to my garage to give better installation.
Picked door up free off gumtree.
