Jablite is the UK's largest producer of EPS products for insulation and civil engineering applications

Profile Roof Insulation


Jablite profile roof insulation is bespoke designed to match any profiled roof and is suitable for new or refurbishment applications.

Installation of Jablite profile roof insulation will increase the thermal performance of existing insulated cladding systems.

The insulation boards are designed to fit tightly into the profile of roof and to eliminate air gaps beween the insulation and the roof system that could cause condensation.

Jablite will supply a sample insulation board to check accuracy of fitting before the full order is delivered.

Technical information
Product specification

Jablite profiled board is supplied:

In  EPS 100 and EPS 150 as defined in BS EN 13163.
Maximum size: 2440 x 1220 x 610mm
Cut to exactly match the profiled shape it will be installed on
To any board thickness depending on construction or thermal requirements
With a flame-retardant additive achieving Fire Class E


The following factory-bonded finishes are available for boards with a flat top surface:

 High performance felt underlay to BS 747
SBS polymer modified membrane

Thermal Conductivity (K value)

Jablite profiled board has the following values for thermal conductivity (k-value):

EPS100 0.036 W/mK
EPS150 0.035 W/mK



The U-value is calculated on an average depth of the profiled board. The required U-value can be achieved by any given combination of existing cladding, insulation and weathering finish and must therefore be assessed individually.



+Does Jablite manufacture to ISO 14001?
Yes, Jablite is certified to the BS EN ISO 14001 Environmental Management System standard.
+Does Jablite EPS include any recycled material?
