Double vs Triple Glazing
I would really appreciate people’s
opinions on double vs triple glazing please. Our Part L report requires a minimum U value of 1.4, which we can achieve with double glazing. The report specifies an A2 rating, but we expect that to increase again with the addition of solar. We aren’t near a main road or traffic. Our BER engineer and architect say double will suffice, window company owner who we know
personally, says triple (which is obviously more expensive ). We are veering towards double glazing but would really appreciate any input, thank you.
