The Vacupor insulation has been applied to the ground floor slab at Passfield Drive.

Vacupor is a vacuum foil insulation which has very low thermal conductivity enabling us to achieve a low U – Value in the floor whilst only adding 25mm to the height of the floor.

The manufacturers state that Vacupor has a thermal conductivity of 0,005 W / (m×K).

Because the thermal performance of the insulation is reliant on the vacuum inside the panels it is vital that the insulation is not perforated, if a panel is perforated that panel no longer contains a vacuum and its thermal resistance is greatly reduced. To protect against this a protective layer must be laid above and below the insulation. To avoid thermal bridges in gaps between panels the insulation is manufactured to fit the floor area exactly
