Kemwell Impact Board
A1 non-combustible high performance fire, blast and impact protection board for critical applications in the commercial, industrial, transport and energy sectors
Kemwell Impact Board is a non-combustible fire, blast and impact protection board and barrier system used for critical internal and external applications in the commercial, industrial, transport and energy sectors.
The consequences of fire, blast or impact are often catastrophic, but they can be reduced and managed with a correctly designed and installed fire safety and protection system in place. Kemwell Impact Board plays a crucial role in providing protection to people, buildings, services, businesses, and the environment.
Impact Board systems are typically used for the construction of walls and standalone barriers, ceilings, roofs, stairwells and ductwork or cable protection.
Impact Board combines lightness, strength, impact, blast resistance and durability with exceptional fire resistance, ensuring continued protection. Kemwell Impact Board will withstand an explosion, followed by prolonged fire, and will be unaffected by firefighters’ hoses or sprinkler systems. It is a tested, proven and certified solution, maintaining structural integrity and providing 4 hours’ fire containment in the event of a fire.

Kemwell Impact Board provides exceptional fire protection and is classed as non-combustible to BS 476: Part 4: 1970, BS EN 1716: 2010, BS EN 1182: 2010 and A1 to Clause 10 of BS EN 13501- 1:2002. Euro Class A1 and A1FL.
Building Regulations stipulate minimum periods of fire protection required to the elements of a building’s structure. In the severest of situations, when protection is needed for up to 4 hours integrity and insulation, Kemwell Impact Board has been tested to meet this criterion in accordance with the requirements of BS476: Part 22:1987 and BS 476: Part 20-24 BS EN 1364-1 & 2.
It also provides up to 3 hours for hydrocarbon fire barriers. Kemwell Impact Board systems are tested to H0, H60 and H120 fire rating for hydrocarbon fire resistance post-blast.
Moisture Weather Resistant
Kemwell Impact Board provides exceptional resistance to the harmful effects of excessive weather and performance is also unaffected by the use of fire-fighters hoses and sprinkler systems.
Dimensional Stability and Strength
Kemwell Impact Board is an exceptional strong and stable product. It is tested from 0.3 to 2 bar over pressure for blast resistance and meets the requirements of BS EN 1128 for heavy impact resistance.
Due to this stability and strength, it ensures that if the boards are subject to high levels of fire, moisture, blast or impact, the boards will continue to provide the levels of protection required for the application in question.
Acoustic and Thermal Benefits
Boards have the added benefit of providing low sound transmission and good acoustic insulation performance. Thermal conductivity is 0.55 W/m K at 20°C.
Kemwell Impact Boards are adaptable, slim, lightweight with a space saving profile and do not require foundations for installation. Impact Boards are suitable for high-speed installation.
Boards are also fully demountable and relocatable, and suitable for retro-installation, unlike plasterboard or blockwork installations.
Kemwell Impact Board is a chemically stable board, unaffected by many diluted chemicals, as well as the harmful effects of weathering and pollutants.
As standard, Kemwell Impact Board is self-finished in either galvanised or stainless steel and requires no decoration.
If decoration is required, boards should be de-greased with a solvent based cleaning agent before any form of decoration is applied. For painting a Zinc Phosphate Primer is required and you should seek paint manufacturers recommendations.
Kemwell Impact Board is a robust and maintenance-free ‘fit and forget’ system even in severe situations and has an expected service life of at least 40 years. The fibre reinforced cement core is environmental friendly with a low carbon footprint.
Kemwell Impact Board is immune to attack from insects or vermin.
