‼️ Buildings that Perform.

Surely that’s a given!

Only if you know what performance is - comfortable, healthy, low carbon, low or no energy buildings - and then how to design, deliver and quality assure them.

Is #passivhaus the answer?

See you there!

Installing intello plus air tightness membrane into a mock up of a roof/ceiling of a timber house

Taping details of connoting the air tightness membrane to the timber joists

Wind membrane installed between rafters to prevent wind washing thermal bypass, followed by Rockwool insulation

How you may insulate between I joists, using layers of insulation with staggered joints to prevent any gaps from front to back

Yesterday I spent the day with @be-stbuild.bsky.social & @coaction.bsky.social putting Passive House theory into practice. In the morning sequencing insulation and membranes into a retrofit rig. So helpful even as a homeowner and not being in the trade.
