Product specification

Jablite HP External insulation is supplied:

In boards sized 1200 x 600mm
To work with Jablite BaseTherm™ board, a low moisture absorbent insulation board used as the plinth of the external wall installation

 

Current Thermal Performance Requirements:
The required ‘U’ value for new insulated buildings or for a refurbishment project is below 0.30 W/m²K.

Typically Jablite High Performance (HP) External Insulation specified to a thickness 90mm or 100mm 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 60mm or 40mm for specific areas where 90mm is not suitable – for example in the alleys of adjoining properties.

Thermal Resistance (R value)

The thermal resistance or R-value of Jablite High Peformance board for the following standard thicknesses is:

40mm 1.25m²K/W
50mm 1.56m²K/W
60mm 1.88m²K/W
75mm 2.34m²K/W
100mm 3.13m²K/W
110mm 3.44m²K/W
120mm 3.75m²K/W
130mm 4.06m²K/W
150mm 4.69m²K/W

 

Jablite High Performance External Insulation is produced to the requirements of BS En 13163 ‘Thermal insulation products for buildings – Factory made products of expanded polystyrene (EPS) – specification’.

External wall (HP) insulation can be installed without having to re-locate the occupants of the property; it will:

• Reduce condensation and heat loss
• Cut heating bills
• Protect and prolong the external fabric of the property
• Reduce CO2 emissions
• Improve the attractiveness of the area

FAQ
+Does Jablite’s manufacturing process use a lot of energy?
No. Compared with other insulation materials, the manufacturing process uses only small amounts of energy as the Jablite EPS bead is expanded by steam.
+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.
+What is the Global Warming Potential of Jablite EPS?
Jablite EPS has a Global Warming Potential of less than 5.
+Can Jablite EPS be recycled?
Yes. Jablite EPS is 100% recyclable
