ACTIS insulation, the manufacturer of leading multifoil insulation products, has announced that its newest product, HCONTROL REFLEX+, has received certification from the BBA (British Board of Agreement).
The innovation is a three in one solution consisting of a reflective vapour control layer and an airtight barrier which also acts as supplementary insulation triple purpose qualities made possible thanks to reflective multifoils which benefit from one of the best emissivities on the market.
With only three layers, it achieves an impressive thermal performance of R = 1.74m².K/W when installed between two air voids of 20mm, according to EN 8990. HCONTROL REFLEX+ is thinner than other more complex multifoils for a similar thermal performance and is a water vapour resistant material which is installed between the insulation and the internal lining.
As a vapour control layer, it prevents water vapour diffusion through the fabric of the building which may cause condensation and protects the insulation which may be sensitive to moisture. It is also completely airtight, acting as a barrier against air leakage, stopping warm air escaping from the building and thus preventing heat loss through convection, saving both energy and money.
Matthew King, director of ACTIS UK, said: HCONTROL REFLEX+ is a specially designed vapour control layer with a built in thermal performance. Its three-in-one nature allows the thickness of insulation to be reduced, making it a unique cost effective alternative to any other vapour control layer. BBA certification underlines just how effective it is.
David Curtis, ACTIS UK technical manager explained how the product can help save money through its thermal efficiency: Air leakage in buildings can lead to a significant increase in energy consumption. To optimise the high performance of insulation now required in both new and refurbished buildings, the use of a continuous vapour control layer like HCONTROL REFLEX+ is highly recommended. This ensures optimal air tightness of the building fabric and helps to maintain the insulation performance. But as it acts as supplementary insulation as well, it even helps enhance the thermal performance of the building.
HCONTROL REFLEX+, consists of two metallised coated polyolefin films with reinforcing mesh and one layer of polyester fibre based wadding, glued along a line in the centre and with intermittent welding at the edge. It is suitable for use in both new build and refurbishment projects and in combination with any type of insulation in roofs, walls and floors.
In addition to the new BBA certification, it complies with BS5250 Code of Practice for Control of Condensation in Buildings, has a CE Mark in accordance with EN Standard 13984 as vapour control layer and is certified by the Finnish Research Centre VTT for its thermal insulation performance.
