Actis Triso Super 10 + multifoil insulation blanket Actis Insulation

Actis Triso Super 10+

Thin multifoil insulation for pitch roofs and associated walls

Works by reflecting radiant heat using the outside reflective layers while the inner core elements reduce heat loss through conduction and convection methods.

Used for insulating pitch roofs at rafter level, either above or below the rafter.

Also controls air and vapour movement.

Requires a minimum 25mm air gap on either side of the insulation.

Highly durable, does not create thermal bridging by sagging, shrinking or deforming.

Product Performance

Thermal performance Equivalent to 210mm of mineral wool (λD = 0.04 W/mK)* BIP-001
Emissivity 0.05 EN 16012
Air Permeability Airtight EN 12114
Water vapour resistance Z ≥ 500 MNs/g EN 1931
Water resistance W1 EN 1928 method A, EN 13859-1
Fire test reaction NPD EN 13501-1

* The mineral wool used to establish equivalence conforms to EN 13162, has a declared thermal conductivity of 0.04W/mK and 210mm of this mineral wool has a declared R value of 5.25m2K/W. The thermal performance equivalence is between the two tested roof structures, and includes all the associated heat losses, such as thermal properties of the materials, air leakage and thermal bridging, the structures being designed with realistic and identical airtightness and fractional timber surface area to ensure that the results of the test are representative of commonly used roof structures.

Standards & Approval

Actis Triso Super 10 + has been tested in comparison with mineral wool for a total of 3 months at sites in the UK and France. Energy consumption data was collected from two identical, full scale roof structures at each site, one fitted with Triso Super 10 +, the other insulated with traditional mineral wool. The roof structures were tested concurrently and under a range of identical winter weather conditions. The energy consumption was then calculated for a range of UK winter weather conditions to ensure that the results achieved are valid throughout the UK.
