30mm Promat PROMATECT L500 Fire Protection Board is a versatile non-combustible low density calcium silicate fire insulation board, used for the construction of fire resistant ducts, cladding of sheet metal ducts and to provide fire rated cable and service enclosures.

Promat L500 PROMATECT 30mm is off white in colour and has a smooth sanded surface on one face with a lightly honeycombed texture on the reverse face.

The Promatect L500 fire-proof board provides excellent fire insulation properties with 30 to 240 minutes fire resistance.

PROMATECT-L500 PROMAT is resistant to the effects of moisture and will not physically deteriorate when used in damp or humid conditions.

Performance characteristics are not degraded by age or moisture.

Untreated surfaces will absorb water which can cause some loss of strength but full strength is regained after drying.

It will not encourage mould growth and is resistant to attack by insects or vermin.

Promat Promatect L500 is chemically inert and is resistant to dilute acids and alkalis.

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.
