126mm Recticel Plylok PIR Warm Flat Roof Insulation Board is a 3 in 1 solution to provide decking, vapour control layer and insulation in one application for use in warm flat roofs under traditional bituminous waterproofing and single-ply waterproofing membranes in new build and refurbishment flat roof projects.

Plylok 2400mm x 1200mm consists of a polyisocyanurate rigid foam insulation core, with a thermal conductivity of 0.022W/mK, and low emissivity aluminium foil facings on both sides bonded to a 6mm plywood top layer.

Recticel Plylok provides long term energy savings for building means of reducing CO2 emissions and for compliance with Building Regulations and Standards.

Manufactured using zero ozone depletion potential (ODP) blowing agents with low global warming potential (GWP).

Recticel Plylok® is a thermal insulation board with high compressive strength and dimensional stability meaning it's the ideal choice for contractors and installers.

The insulation core and facings resist attack by mould and microbial growth.

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.
