Can anyone please help.
The calculation of U values for triple glazing panels
If you have a glazing panel, made up as 4-20-4-18-6.8, soft coat, soft coal, Lam/tuf glass with warm edge spacers and argon filled is it possible to reduce the air gap to 10mm and 10mm and still achieve the same thermal efficiency.
Everything i have found on line suggests it is not possible.
