50mm Duct and Pipe Wrap (45kg/m3) Roll is a reinforced aluminium foil faced mineral wool non-combustible class A1 roll used for heating and ventilation pipe or duct work and liquid storage vessels.

HVAC Lamella Mat is manufactured with a density of 45kg/m3 with excellent fire performance, classified as Class A1 to BS EN ISO 13501-1, which is the highest fire classification available.

Mineral Wool Foil Faced Duct Roll is a high performance solution which provides acoustic, thermal and fire insulation properties with an excellent anti condensation and moisture features.

Foil Backed Roll also meets the requirements of BS 476: Part 4: 1970 (1984), Class 1 Surface Spread of Flame to BS 476: Part 7 1997 and Class ‘O’ to the Building Regulations.

This means that it will not contribute to the spread of fire and will not produce a large amount of flame when exposed to fire.

Lamella Roll can be used to insulate pipes and ducts in buildings which will help to prevent condensation from forming on the pipes and ducts.

HVAC Mineral Wool Lamella Mat is free from CFCs, HCFCs and any other material with ozone depletion potential and does not absorb moisture.

Foil Faced Mineral Wool Roll is easy to handle and install, being lightweight and easy to cut to size.

Mineral Wool Duct Roll will not swell or degrade when exposed to moisture, suitable for applications where moisture resistance is important.

Lamella Roll must be joint sealed with aluminium foil self-adhesive tape to achieve maximum performance.

Alternatively, you can work it out yourself quickly and easily: to get cost per meter square please divide price shown in orange area by ''Required area (m2)'' Example price of £28.80 divided by board coverage 2.88m2 = cost of £10.00 per m2.


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.
