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 existing profiled roofs. A sample insulation board is provided to check accuracy of fitting before the full order is delivered.

Jablite insulation for profile flat roof systems is:

• Suitable for new or refurbishment applications
• Designed to increase the thermal performance of existing insulated cladding systems
• Cut to fit tightly into the profile of roof
• Designed to eliminate air gaps between the insulation and the roof system

  • Bespoke designed to each roof or cladding
  • Improves the aesthetic appearance of old roofs
  • Extends the life of an old roof
  • Provides a good surface for a new waterproof membrane
  • Reduces the risk of condensation
  • Fast installation
  • Is durable, lightweight and easy to handle
  • Provides long lasting dimensional stability

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?
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.
+How are Jablite products rated in the BRE Green Guide to Specification?
Jablite manufactures EPS (expanded polystyrene) products which are A+ rated in the BRE Green Guide, except for Jablite 300 grade insulation for inverted roofs which has an A rating
