In a bid to remain faithful to their mantra: “Take control of your energy costs”, Rigifoam recently renewed their commitment to the supply of insulation capable of reducing operational heating and cooling costs, resulting in positive environmental and climate change consequences. Their launch product, Lamdaboard, is a unique solution to the energy crisis.
Lamdaboard can be made with a multitude of different facings:
- Mineral coated glass fibre tissue – matt finish.
- HDPE Valeron coated glass fibre tissue – washable gloss finish.
- Embossed or smooth aluminium foil and scrim reinforced foil for duct applications.
In the process, the foam bonds to the facing, providing a seamless look.
Foil and plastic facings on Lambdaboard help stabilise the R-value. Lambdaboard complies with the Montreal and Kyoto protocols. As the product is cut to length per order, there are no off-cuts or wastage.
Lambdaboard is manufactured from polyisocyanurate, a thermosetting plastic, closed cell foam that contains a low-conductivity gas in its cells. The high thermal resistance of this gas is what gives polyisocyanurate insulation materials an R-value suitable for effective insulation.
Lamdaboard is used as thermal insulation with its main installation being overhead applications, ceilings and over-purlin. It can also be used for cavity wall insulation, interior wall cladding and inverted roofs. Being a closed cell foam with high compressive strengths, it can also be used as under screed insulation.
