Passive House Floor Insulation

The monitoring of built passive house has shown that the insulation effect of the thick insulation layers meets exactly the expectation.

Passive house floor insulation.

It s important to maximise passive solar gain meaning the sun is used as often as possible to heat the air and water the home consumes on a daily basis. Typical conventional insulation materials mineral wool polystyrene cellulose require layers of about 30 cm. 2 xtratherm detail showing upstand of insulation around the edge of the floor slab to minimise thermal bridging with the inner leaf of the cavity wall. 3 200mm kingspan insulated.

State of the art vacuum insulation materials allow for very slender yet highly insulated. A passive house is a building for which thermal comfort iso 7730 can be achieved solely by post heating or post cooling of the fresh air mass which is required to achieve sufficient indoor air quality conditions without the need for additional recirculation of air. Insulation and ventilation are both important components in the design and build of a passive house but there s still much more to it. Even a straw bale wall of 50 cm or more would be suitable for the passive house.

The thickness can even be reduced to 20 cm with common polyurethane foam insulation materials. 1 foundation detail at denby dale the uk s first certified cavity wall passive house with a lightweight insulating concrete block at the wall to floor junction.
