PROMATECT-MST PROMAT Fire Resistant Board is a 50mm x 1200mm x 2500mm non-combustible class A1 rigid machinable insulation board used as a thermal break in process plants and as single skin insulation in ovens and dryers.

Fire Protection Board Promatect-MST is an effective and stable fire insulation solution for demanding applications, its low shrinkage and very good rigidity properties even when exposed to high temperatures of 1000ºC.

50mm PROMATECT®–MST PROMAT is a calcium silicate based building board, a rigid class A1 insulation board with up to 240 minutes fire resistance and low thermal conductivity that can be easily machined to close tolerances.

Promatect–MST Fire Protection Boards have low shrinkage and high strength and therefore provide effective and stable insulation solutions for oil, gas and heavy industrial applications.

This high-performance fire protection board can also be used as a load bearing pipe support, heat shield, structural thermal break and furnace bottom board.

PROMATECT–MST products can be accurately machined with special processing machinery and appropriate tools.

The fine material structure allows the production of precision machined parts.

When cutting to size, the maximum workplace concentration values for inhalable dust must be observed (dust extraction is recommended).

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.
