August 15, 20233 yr I'm starting to think about heat losses. Not the normal one's, like floor, walls, windows, doors, and roof. The odd ones that i also need to consider. Things like where the wall meets the floor. Where the windows meet the wall reveals. Window lintels. Where the roof meets the walls. Pipe penetrations from inside to outside. Are there any others that people can think of ? Don't want to miss any if i can. Thanks in advance.
August 15, 20233 yr Author @SteamyTea Yes, Both how to calculate them, and thinking about what i might be able to do to make them a bit better.
August 15, 20233 yr I did a bit about calculating periphery heat losses on here a while back. It is not a a BSI standard, but was close enough. Basically you add the aperture/wall thickness to the total wall area, then calculate as normal.

Periphery insulation and extending cavity insulation down to the foundation. 1 hour ago, Big Jimbo said: Where the windows meet the wall reveals. Windows sat in cavity as much as possible, tape joins. 1 hour ago, Big Jimbo said: Window lintels. Two separate lintels in each leaf (brick and block only) 1 hour ago, Big Jimbo said: Where the roof meets the walls. Warm roof and insulation continues from cavity into roof . 1 hour ago, Big Jimbo said: Pipe penetrations from inside to outside. Few or None, unless down through an insulated slab and if unavoidable insulated to death.

August 16, 20233 yr @Big Jimbo I think I'm right in saying you have a block cavity design. have you seen the denby dale videos on you tube?
