1.2m x 25m Bubble Foil Insulation

1.2m x 25m 30 SQM Bubble Foil Insulation

DOUBLE foil insulation which works on the principle of reflecting approximately 95% radiant heat back in to the building. 
The main advantage over single foil being it also reflects too much heat back out ( ideal on roofs ) . 
The thermal performance our bubble foil has it is unaffected by moisture and condensation. 
We recommend sealing joints with Yuzet® aluminium foil tape.

Typical installation applications; ( to boost thermal performance )
Roofs (example, External tiles, Our Foil, Cavity, batten finish, boards. )
Walls.
Outdoor buildings & caravans
