Jablite external wall insulation is an easy-to-install insulation that will perform for the lifetime of the building.
Jablite external wall insulation is compatible with all external wall systems and can be bonded or mechanically fixed to the wall.
Installing insulation on the external walls of a domestic or non-domestic property is a cost effective alternative to demolishing and rebuilding.

Current Building Regulations
The required ‘U’ value for new insulated buildings or for a refurbishment project is below 0.30 W/m²K.
Typically Jablite External Insulation specified to a thickness 110 mm or 120 mm will achieve the required u-value of 0.30 W/m²K as part of an insulated render system on a solid wall. In addition you can specify 70 mm or 60 mm for specific areas where 90 mm is not suitable – for example in the alleys of adjoining properties.
Jablite insulation is produced to the requirements of BS En 13163 ‘Thermal insulation products for buildings – Factory made products of expanded polystyrene (EPS) – specification’.
The thermal resistance or R-value of Jablite External Insulation boards for the following standard thicknesses is:
| 40mm | 1.05m²K/W |
| 50mm | 1.30m ²K/W |
| 60mm | 1.55m²K/W |
| 75mm | 1.95m²K/W |
| 80mm | 2.10m²K/W |
| 100mm | 2.60m²K/W |
| 110mm | 2.89m²K/W |
| 120mm | 3.15m²K/W |
| 130mm | 3.42m²K/W |
| 150mm | 3.95m²K/W |

| + | Does Jablite EPS include any recycled material? |
| Yes. Jablite standard products use between 0% and 60% recycled material depending on the grade, type of product and recycled material availability. The recycled material is from off site sources e.g. clean offcuts from building sites or from the manufacturing process - 100% of Jablite's manufacturing EPS waste goes back into the manufacturing process. | |
| + | Is Jablite packaging environmentally friendly? |
| Jablite is continuously striving to reduce packaging on its products. Products are wrapped in film as and when necessary to protect them during transport and storage on site. Ongoing efforts have been made to minimise the thickness of film used to reduce the packaging further. Pallets are used when requested by customers, but wherever possible recyclable EPS 'skids' are used. | |
