FireKem FP-900 Kemwell Multi-purpose Board is a 25mm x 1200mm x 2400mm calcium silicate class A1 fire protection building board used for commercial and industrial applications.

This fire rated board is a perfect solution for internal partitions, external walls, roofs, floors and ceilings, and is particularly suited for dry wall construction applications.

Kemwell FireKem FP-900 fire protection boards are approved for up to 240 minutes fire resistance according to BS 476: Part 22: 1987 depending on application.

25mm FireKem FP-900 provides very good acoustic reduction performance of between 26-49dB and also provides thermal conductivity (approx.) at 20°C of 0.17 W/mK.

The inherent alkalinity of the board makes it anti-bacterial, meaning it is suitable for use in conditions where hygiene is of concern,  such as hospitals or food-preparation areas.

It provides superior fire resistance performance and excellent dimensional stability under heat and severe moisture environments making it an ideal choice for a variety of projects.

25mm Kemwell FireKem FP-900 has a smooth surface but due to their high suction should be first sealed prior to applying paints, plasters, or wallpapers.

It is recommended that cutting of the boards is carried out in well-ventilated situations, or the wearing of suitable dust masks.

Kemwell Boards may be flat head nailed or pilot drilled, then screwed.

No matter whether you choose a local installer or a national company, there’s a few tips to help you find the right installer for your home insulation improvements, such as asking for recommendations and making sure that they’re part of a certification scheme. This makes sure that they have the right skills and standards of workmanship to carry out the installation, and you can be sure that they know exactly what they are doing.


1. Thermal inspection picture in portfolio

It’s worth seeing a installer’s previous work. There’s no harm asking if you can see any properties nearby that they’ve installed insulation in. Best way would be to see Infrared Thermal Imaging Inspections. Thermal cameras spot small, but key changes in temperature in different areas of a house, identifying problematic areas that the human eye never could and some that a visual inspection could only hypothesize.

2. Reviews

Along with checking recommendations and previous work, finding reviews online can often be a great way to find out if they provide a good service or not. However, it’s best not to solely rely on reviews you may find or review websites, as there’s no controlling who writes them.

3. Compare prices

Comparing prices will also ensure companies can’t take advantage of you and give you a fair price. 

4. Word of Mouth

The best way to find a great insulation installer is through recommendations. Make sure you ask friends and family. They will most likely give you their honest opinion and can tell you from first hand experience.


Whether you require a wall, cladding, external wall, loft or floor insulation fitted, you can find and hire your local insulation installers from popular UK web pages. A simple internet search will return thousands of potential installers near your area.
