Fire stop batts are a 60mm thick lightweight flexible high-density mineral fibre barrier system coated with a white fire resistant barrier coat.
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.
The fire stop batts 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.

Supplied as an-off white powder in 20kg sacks, it is mixed with water and is exceptionally economical in use:-
50mm depth -37kg/m dry powder -1.85 bags (1 hour)
75mm depth -56kg/m dry powder -2.8 bags (2 hours)
100mm depth -75kg/m dry powder -3.75 bags (4 hours)
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 + insulation.
Intulight - 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, 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. Made to order at no extra cost.
Firetherm 30/90 - As Firetherm 30/90 is manufactured from densely woven glass cloth, coated to prevent fibre migration, it is particularly suitable for use in food processing and pharmaceutical plants, super stores and computer installations where dust undesirable.
Intupillow - 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. Ideal for use around frequently changed computer or data cables as they can be removed or replaced.
Intucollar-T - Intucollar is constructed from a metal shell produced in two hinged halves, lined with intumescent material, to be placed around PVCu pipework and fixed to the adjacent masonry with the all steel fixing kit supplied to provide up to 2 hours fire protection. In a fire, the intumescent lining of the metal collar expands to crush the heat-softened pipe, so creating a fire seal. A 4 hour collar is also available to special order
Intucollar-E - 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 4hrs 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. Intucollar E is highly cost effective and supplied in flat pack form to be made up quickly and easily on site.
Intuband - A sealed plastic sleeve containing 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 - 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.
