20mm Stylite Plustherm Grey EPS EWI 70 External Wall Insulation Board is a high performance thermal insulation board manufactured from Expanded Polystyrene (EPS), used in External Wall Insulation (EWI) systems to meet Building Regulations for thermal performance.
Stylite Expanded Polystyrene Insulation Board 1200mm x 600mm x 20mm is a perfect solution that can be easily fixed to the existing wall substrate to instantly improve the appearance and performance of the wall.
20mm Grey External Wall Polystyrene Insulation Board is compatible for use with many different wall constructions, from solid brickwork to timber frame walls.
Insulating the external side of the wall as opposed to the internal side of the wall will reduce the risk of any interstitial condensation forming within the wall.
Typically external wall insulation is covered with a rendered finish which will protect the insulation, this can be applied in many different ways depending on the system used.
Graphite EPS Insulation is the most popular thermal insulation material used in external wall insulation systems due to its great value for money.
Choosing a cost-effective Grey EPS EWI 70 External Wall Insulation Board you can cut down the cost of your insulation without loosing quality or thermal performance of your building.

Installation of EWI Grey Polystyrene Insulation:
· Grey polystyrene has the same adhesive properties as white polystyrene and there is no obligation to sand it before sticking.
· However, wiping the polystyrene surface before sticking (regardless of its color) improves the adhesion of the adhesive to the fixing.
· The surface grinding operation must be performed on the upper side, before embedding the mesh.
How to stick Grey EPS Insulation Boards:
· Some manufacturers recommend gluing graphite polystyrene boards using a universal adhesive intended for embedding the mesh and for fixing polystyrene, not only polystyrene adhesive.
· Experience shows that if we buy a really good polystyrene adhesive, it will work.
· It is worth recalling that each polystyrene should be glued with the circumferential-point method.
· After applying the glue, it should be on at least 40% of the board surface.
· Dot and dab method should not be used anymore, but still many contractors stick polystyrene only to "dabs", insisting that they have been doing it for years and it is fine.
· This error can cause the boards to fall off, especially those made of graphite polystyrene.

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.
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.
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.
