Hello
I am new to this forum but have already read a lot and found useful advice. Now I need to start my own topic because I simply can’t find anything on the internet.
In three weeks, we will be getting a new patio roof. We are really excited about having a conservatory, but unfortunately, that’s not possible at the moment. To save money, I would like to build it myself. I already have a contact for aluminum profiles.
Now the question is whether to go for double glazing or just tempered glass (toughened safety glass). My father-in-law says I should definitely choose double glazing. The roof consists of 10mm laminated safety glass (VSG). The aluminum profiles are not insulated. Does it make sense to use double glazing for the sliding glass walls in this case? It needs to be closed on both sides and the front, all planned with sliding panels. In terms of cost, I could build a cold conservatory for about 4,000€ (around 4,400 USD). With different profiles for double glazing and the double glazing itself, the price goes directly to about 12,000€ (around 13,200 USD).
Who has experience with cold conservatories and can offer some tips?
To what extent can a cold conservatory be heated? For example, with a fireplace or two infrared heaters.
Is it possible to use it during winter with heating options? Maybe even when it’s below freezing?
I hope to hear from someone soon. Until then.

Hello again,
I have now found a formula to calculate the heating power:
Glass area x U-value x temperature difference between outside and inside (let’s say -5°C (23°F) to 20°C (68°F))
This means:
Glass roof: 26 x 5.7 x 25 = 3705 watts
Uninsulated glass walls: 33 x 5.7 x 25 = 4702 watts
Insulated glass walls: 33 x 1.1 x 25 = 907 watts
So I would need 3705 watts + 4702 watts to have enough power to heat a cold conservatory to 20°C (68°F).
If I use insulated glazing, I would need 4702 watts minus 907 watts less.
Is this correct, or am I completely wrong?
