35mm EcoTherm EcoVersal PIR Insulation Board 5 in 1 Solution is a universal multi-purpose fibre free rigid polyisocyanurate insulation core faced with an aluminium foil composite on both sides designed for insulating pitched roofs, floors, walls, ceilings and dormer cheeks.

Ecotherm Eco-Versal 2400mm x 1200mm x 35mm is suitable for a wide range of applications including both new build and upgrading the thermal performance of existing building elements, providing a cost effective means of reducing CO2 emissions and for compliance with Building Regulations.

Eco-Versal has a thermal conductivity (lambda value) of 0.022 W/mK with low emissivity surface of the reflective foil which can help improve U-values in certain constructions when reflecting into a cavity.

The compressive strength of Eco-Versal typically exceeds 140 kPa when tested at 10% compression to BS EN 826: 2013 (Thermal insulating products for building applications. Determination of compressive behaviour).  

Eco-Versal is suitable for use with most Underfloor Heating Systems (UFH) and if correctly installed, Eco-Versal has an indefinite life.

EcoTherm Eco-Versal PIR Insulation Board can be used to insulate: solid floors (above and below slab), suspended block and beam floors, suspended floating timber floors (between and over the joists), walls (between and inside timber studs), insulated sheathing, roofs, ceilings, dormer cheeks (between, over and under rafter).

We can help to calculate price per m2 or linear meter (one meter in length) cost, please just contact us via phone 02081910776, email or live chat. 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.
