The Siderise Sound+ Acoustic Foam Slab (12mm) is a high-performance open-cell polyurethane polyether foam designed to reduce airborne noise and control reverberation in demanding acoustic environments.

Lightweight yet effective, it delivers a weighted sound absorption coefficient (αw) of 0.30 at 12mm thickness, providing efficient acoustic treatment in space-limited installations.

Its combustion-modified composition ensures compliance with BS 5852 Part 2 Crib V, FMVSS 302, and UL94 HF1 flammability standards.

Ideal for duct lining, machinery enclosures, and acoustic infill panels, this flexible material is simple to cut and install across commercial and industrial projects.

INSTALLERS

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.

4 TIPS FOR CHOOSING THE BEST INSULATION INSTALLER

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.
