Insulation using Warmfast Fixings and Vapour barrier
Celotex TA4000, FR & TR
Ecotherm – Ecofix Download Data Sheet
*Are rigid boards allowing
installation of hard metals directly onto the insulation using Warmfast Fixings which secure the insulation and the metal to the deck without creating a cold bridge. The deck can be timber OR trapezoidal metal. Warmfast vapour barrier must also be used above the deck on the warm side of the insulation.
Linitherm PGV FLEX is also a rigid, yet flexible insulation allowing installation of metal directly to insulation over curved surfaces, ideal for barrel vault designs. Being rigid and flexible, this is the best insulation to use for this type of construction. When installing metal directly to a curved surface, it prevents the oil canning effect and noticeable faceting of other rigid boards that have to be cut to shape. PGV Flex is also fixed using Warmfast fixings. Warmfast vapour barrier should also be used.
Metdeck is a high quality Kingspan rigid board bonded to 18mm exterior grade plywood. Metdeck offers high insulation value with minimal construction height.
Linitherm PAL OSB is a highly engineered rigid board bonded to 22mm exterior grade OSB. All edges of both the OSB and the Insulation itself are channelled preventing the uncontrolled vapour drive that occurs with butt jointed insulation boards. The technical team at Linzmeir are on hand to assist with all technical aspects from start to finish ensuring that the whole system works in harmony. Warmfast Vapour Barrier should also be used.
Puren M is a combination of rigid board with timber lathes bonded at 600 centres. Puren provide
the whole system including vapour barrier. As with Linitherm,the technical team at Mifaro, (Worldwide suppliers of Puren M to the distributor market) are on hand to assist with all technical aspects from start to finish ensuring that the whole system works in harmony.
Foamglas is a closed cell insulation impervious to vapour and highly fire resistant. One of, if not the only solution accepted for a majority of metal manufacturers when installing metal over a swimming pool. Being a total vapour barrier, any product on its outer surface is protected from the highest of vapour drives. Foamglas also offer insulation wall cladding. Due to Foamglas being impervious to water, Pittburgh Corning, manufacturer of the products, have introduced a tanking version ideal for basement conversions ensuring that development below the water table can be carried out and remain dry at all times for as long as the building stands.
