100mm Grey EPS for External Wall Insulation (Graphite Expanded Polystyrene) is an insulating material with about 20-25% better thermal insulation properties than basic white EPS that can effectively reduce heating costs and improve the appearance of the building.
Complete external wall insulation made of grey polystyrene is durable and maintains its functional properties throughout the entire life of the building.
External insulation systems based on grey polystyrene for building facades are a proven solution that has been used in construction for over 50 years.
The difference between white and grey polystyrene is the presence of graphite, which is added to the expanded polystyrene during the production process.
As a result, you get polystyrene with a grey tint, but more importantly - also with increased thermal insulation properties.
It allows the use of a thinner layer of insulation without compromising the insulation parameters of the wall.
Grey EPS is mainly intended for investors who want to achieve the standard of an energy-saving or passive house.
The technical conditions regarding the maximum heat transfer coefficient through external walls mean that investors are forced to insulate their houses with thicker and thicker layers of insulation.
In this situation, graphite polystyrene for external wall insulation comes in handy.
Overall it is cost effective as better insulation material means lower heating bills.
Thermal conductivity: 0.031 W/mK - improved over basic white polystyrene boards.

Preparations for the installation of graphite polystyrene:
Graphite 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.
What glue for graphite polystyrene?
Some manufacturers recommend gluing graphite polystyrene boards using a universal adhesive intended for embedding the mesh and for fixing polystyrene, not only polystyrene adhesive.
We recommend Ceresit ZU Insulation Adhesive, Ceresit CT87 White Flexible Adhesive or Ceresit CT84 Express PU Foam 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.
Transport and storage:
Graphite façade polystyrene boards absorb more sunlight than standard (white) boards.
Therefore, they should be protected against direct sunlight, both during transport and storage.
Failure to secure the insulation boards may cause the so-called "Melting", causing the destruction of their structure.
During construction works, the outside temperature of the air, the substrate and the built-in material must not be less than + 5 °C and not more than + 25 °C.
During the works, the material must not be exposed to direct sunlight.
Scaffold nets, for example, can be used as protection against the sun's rays.
Certification:
Produced to the requirements of EN-13163 Standard.

We do not deliver on weekends and bank holidays. Sometimes we can deliver on Saturdays - please check with us before placing the order.
If you need any further information please contact us tel. 02081910776
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.
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.
