At Alpha Fire And Air Solutions Limited, we provide fire stopping and prevention solutions in the hope of helping to prevent blazes from causing serious damage. Our fire stop batts are used to provide a fire barrier in compartment walls and floors, under raised floor tiles, above false ceilings, and within plant rooms to achieve a minimum of one-hour fire protection and cold smoke seal. Call us now to learn more
Fire stop batts are 60mm-thick, lightweight, flexible, high-density, mineral-fibre barrier systems that are coated with a white fire-resistant barrier coat. These have been widely tested to BS476 part 20, and are approved as a vertical barrier up to 3m in height with integral support and are resistant to moisture, movement, and vibration. If additional services are required once the fire stop batt system has been installed, pipes and cables can easily be installed with no additional maintenance required if a tight fit is achieved.
Nullifire™ water-resistant compressible seal offers fire, smoke, and acoustic performance for horizontal and vertical structural movement joints, with up to 50% movement.
FS701 - FLEXIBLE ACRYLIC MASTIC
This is an internal water-borne Intumescent acrylic mastic offering fire, smoke, and acoustic performance for horizontal and vertical structural movement joints with up to 10% movement.
FS703 - FLEXIBLESILICONE MASTIC
This is external silicone mastic. It offers fire, smoke, and acoustic performance for horizontal and vertical structural movement joints with up to 40% movement
FB747-50.60 - FIRE RATED BATTS
This lightweight mineral fibre barrier is coated either side with acrylic mastic. It prevents the passage of toxic gasses, smoke, and fire between compartments. Also, it offers acoustic and thermal insulation.
FB805/FB810 - FIRE RATED FLEXIBLE CURTAIN
This is a lightweight, flexible fire-rated fabric. Designed to be stretched between perimeter fixings to prevent the passage of smoke or fire, this is an effective product.
FB760 - FIRE RATED INTUMESCENT SEAL BAGS
These are our temporary or permanent fire-rated seal bags. These hard-wearing fabric bags are designed to fill wall or floor penetration and are easily modified for new services.
FB150 / FB150 2 HOURS / FB150 4 HOURS - FIRE RATED PIPE COLLAR
These surface-mounted Intumescent pipe wraps designed to close off PVC and uPVC pipes, preventing the passage of smoke and fire.
FB300 - FIRE RATED PIPE WRAPS
Internally located, these intumescent pipe wraps are designed to close off PVC and uPVC pipes, preventing the passage of smoke and fire.
FR220 / FR240 / FR270 - FIRE RATED COMPOUND
Made from load-bearing and non-load-bearing compounds, these are designed to seal around multi-service penetrations.
INTUBATTS - FIRE RATED BATTS
This is a high-density, mineral-fibre batt coated with durable, fire-resistant mastic measuring 1200x600x50mm. The mastic is white and provides class-1 spread of flame. Supplied and packed in strong polythene bags, Intubatts™ can be cut with a serrated knife or padsaw. The Intubatt system is suitable to fire stop holes in walls and floors where there is no loading bearing requirement. Refer to the Intubatt installation instructions for further details. No "coat back" of penetrating services is necessary.
INTUCOMPOUND - FIRE RATED COMPOUND
Supplied as an-off white powder in 20kg sacks, it is mixed with water and is exceptionally economical in use:
Intucompound can be used to provide load-bearing fire seals in floors or to support fire dampers in walls. Up to 4 hours’ fire integrity and insulation.
This product is designed to overcome a common problem where a light-box or downlighter unit breaks through a fire-rated suspended ceiling. If left open, this creates an obvious path for a fire to exploit, allowing it to gain access to a cavity which could lead to the fire spreading unseen and unchecked around the building. Constructed from compressed mineral fibre and coated with foil to reduce free fibre migration to a minimum, Firetherm's™ solution is easier to install than "tented" types and more cost effective. This can be made to order at no extra cost.
These are fire-resistant bags filled with a mixture of inorganic filler, intumescent material, and fibres sealed inside a high-quality, glass-fibre woven fabric. In a fire, the contents expand and solidify, becoming solid like a rock, so supporting the penetrating services and holding back the fire for up to 2 hours. Intupillows are moisture resistant and do not contain halogens. They are clean and pleasant to handle, making them ideal for use around frequently changed computer or data cables as they can be removed or replaced.
This is a metal shell lined with intumescent material to be placed around PVC-U pipes and fixed to compartment walls and floors to provide up to 4 hours’ fire integrity. In a fire, the intumescent lining of the metal collar expands, crushing the heat-softened PVC-U pipe sealing a potential path for fire. Highly cost-effective and supplied in flat-pack form, the Intucollar-E can be made up quickly and easily on site with little fuss.
This sealed plastic sleeve contains a high-pressure intumescent sheet, designed to fit around PVCu pipework with a Velcro securing system to provide up to 4 hours’ fire integrity. Most often used in situations where a pipe passes through a hole which requires further fire sealing. Firetherm Intucompound is the perfect companion product for making good after installation.
Intustrap is designed to crush thermal insulation fixed around metallic pipes where it is undesirable to cut into the insulation in the normal way at the point where the firestop is to be constructed. Intustrap consists of a strip of high-pressure intumescent sheet which is wrapped around the insulation twice and secured with strong tape. The fire stop is then installed in the normal way around it.
Silverflame™ fire batt, Silverflame coating and, Pyrocoustic™ sealant are designed to prevent the passage of fire and smoke between compartment walls and floors while still allowing the installation of services. The product is tested to BS 476 part 20/22, giving a fire and smoke barrier for 4 hours. Incorporating Silverflame firewall tested to IMO 754.
Its features include:
PyroPro™ LST fire resistance sealant is a one-part, acrylic emulsion. It is designed to resist the passage of fire, while maintaining smoke and toxicity levels. The sealant will form a char when exposed to the heat of a fire; the reaction from the sealant will prevent the passage of fire and smoke. In normal use, it will maintain the sound reduction index of a structure. It is designed for use within concealed areas such as tunnels and the London Underground. Features include:
Flexi-Coat™ is a water-based elastomeric acrylic coating with excellent fire, water, air permeability, and elastomeric properties, offering high movement. It’s ideal for spray, trowel, brush, and pouring applications. For flexible installations 80kg/m3 stone wool should be used. At normal temperatures, Flexi-Coat remains highly flexible to permit thermal and mechanical movement of services and the building structure. Features include:
