BLACK TISSUE FACED SLAB
Black Tissue Faced (BTF) slab is a type of insulation laminated on one or both sides with a mineralised 70 grams glass fibre fleece that prevents fibre migration where additional tear strength is required for use in thermal and acoustic applications. The aim of this composite insulation product is to dramatically reduce clumping and fibre migration, ensuring a consistent, high thermal performance throughout the entire slab. Since it provides five times less fibre migration it is especially suited for sensitive areas where any loose fibres would cause problems. Therefore is dedicated to be used in suspended ceilings, soffits and ductwork systems.
So called Black Matt Facing (BMF) or Black Glass Tissue (BGT) is bonded using a binder. The coating is adapted to air flow at a speed of 20 m/s without causing entrainment of the fibers. This combination of two non-combustible products provides increased impact resistance and durability in addition to improved fire safety.
Foil faced products retain their powerful properties at temperatures as high as 370°C.
BLACK TISSUE FACED SLAB APPLICATION
Black tissue scrim has been specially developed to be used in suspended ceilings, usually in high tech or sensitive buildings such as schools and hospitals where fibre migration could be a problem. This Anti-fiber migration product is available with either glass fibre or rockfibre insulation. In most circumstances the tissue facing is placed on the warm side of the structure.
The black tissue faced insulation slabs can be used in:
- underground car parks,
- under attic rafters,
- air-conditioning ductwork,
- offshore platforms and ships,
- industrial and commercial buildings to block radiant heat,
- external walls (metal frame, rainscreen, timber frame),
- façade systems (rendered facade, ventilated facade rainscreen cladding),
- HVAC (ducts – acoustic),
- intermediate floors (metal joists, timber joists),
- internal and separating walls,
- separating floors (timber floating floor),
- acoustic ceilings and partition panels.
DIFFERENCE BETWEEN BLACK TISSUE-FACED AND FOIL FACED INSULATION SLABS?
The type of facing affects the overall thermal performance of the insulation slab. The difference between the two is small, but enough to make a difference that is noticeable in U-value calculations.
Foil facings are ‘gas tight’, giving improved long term performance. This results in an insulation slab that has a lower (better) declared thermal conductivity. Aluminium foil facings are more complex than black facing tissue. They comprise a multi-layer build-up that is integral to the performance of the product.
On the other hand ‘black tissue face’ of a tissue-faced insulation slab is, more precisely, a 0.2mm thick silk-like material made by the fiberization process and spraying of thermosetting resin. This stabilises the product to prevent fibre migration. All this helps process temperature control, energy conservation, condensation prevention and personnel protection. Since Black Tissue Facing (BTF) is known as protection against fibre migration it is also resistant to corrosion, unaffected by rodents, it has low moisture rate and good hydrophobicity too.
BLACK TISSUE FACED SLAB SIZES
Black tissue faced slabs come in a size of 1200x600mm and in thicknesses of 25 ǀ 30 ǀ 40 ǀ 50 ǀ 60 ǀ 75 ǀ 100 ǀ 150. This material can be freely cut in construction according to the shape required.
BLACK TISSUE FACED SLAB PRICE
The price of black faced insulation slab is based on the bulk order quantity. The weight of the layer significantly affects the price of the product. The 70 gram scrim (black) is usually 25% cheaper than the 100 gram (white).
