UK company Thermahood, based in Co. Down, Northern Ireland, has chosen LATENE 7H2W-V0 flame retardant polypropylene as the ideal material from which to manufacture its innovative plastic Downlight Attic Seals.
Downlight covers already exist in other materials and allow loft insulation to be continued over downlights thereby reducing heat loss and draughts.
The Thermahood Downlight Attic Seal, made from flame retardant polypropylene, uses a combination of unique design and material selection to provide an airtight seal.
This overcomes any risk of condensation as a result of water vapour transmission into cold attic voids, as well as optimizing the sealing properties.
A strong consideration in the choice of material was the UL 94 certification available for the chosen grade of LATENE 7H2W-V0.
The yellow card certification provided by UL shows the excellent self-extinguishing properties of the polymer which has a flame rating of V0 down to a thickness of 0.75 mm.
Also certified by UL is the Relative Thermal Index which shows that the physical properties of the compound are not unacceptably compromised at a continuous use temperature of 115°C.
LATENE 7H2W-V0 is also free from halogenated flame retardant additives, RoHS compliant, and manufactured by Lati Industria Termoplastici S.p.A. whose environmental management system is certified to ISO 14001.
