Most commonly seen to the underside of metal decking and concrete floors, these boards provide additional insulation (or lower ‘U’ value) to control the loss of heat as required by design and building regulations.
These boards can be fitted either direct to the underside of a floor or to a supporting framework where the surfaces may be uneven or otherwise unsuitable for direct fix methods. Various board finishes are available in the market from foil & plain face, to calcium silicate.
Different boards will provide different levels of insulation and even protection from moisture and low impact along with a Class 0/Class 1 fire rating.
Acoustic/Air Sealing Systems
Building airtightness or ‘envelope airtightness’ can be defined as the resistance to inward or outward air leakage through unintentional leakage points or areas in a building.
These ‘leakages’ can be caused by internal ventilation systems, wind or general air movement creating changes in pressure which may ultimately create increased levels of energy consumption, drafting affects and potential moisture extremes such as condensation.
In order to combat this, insulation-based products and mastics can be used utilised to form a suitable air seal between internal and external sections of a building.
Many of these insulating products also provide a level of acoustic based performance and can be installed for acoustic only, or to combine fire resistance, air seal and achieve specified acoustic ratings.
