Novia VC2 is an innovative, flame resistant, scrim reinforced and airtight vapour check membrane for use in insulated walls, floors and roofs.

Air Leakage and Vapour Control Layer is a extra tough material providing good tensile and nail tear strength.

It is lightweight and easy to handle and install translucent flame resistant to EN 13501-1 material.

Novia VC2 improves the insulation performance and minimizes interstitial condensation risk.

This high-performance, economical solution helps buildings meet the requirements of BS 5250.

The flame resistant additives mean that the membrane will not readily ignite or continue to burn in small fires, which adds an extra level of safety to building designs. 

To provide an airtight seal, it must be installed in conjunction with the Novia two-tape sealing system.

The product is CE-approved and CPR compliant.

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.
