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 and will improve the thermal performance of an existing profile roof and of the building.

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

Jablite manufactures and supplies a sample insulation board to check fitting on the roof profile before it is ordered.

Product specification


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


Can be supplied with factory-bonded finishes:
  •  High performance felt underlay to BS 747
  • SBS polymer modified membrane

Thermal Conductivity (K value)

Grade  K- value
100 0.036 W/mK
150 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.

Compressive Strength

Jablite Profiled Boards are available in grades 70, 100 and 150 to meet performance requirements.

70     The insulation is not under load*

100  Maintenance traffic only

150   Constant foot traffic

Please note the load bearing capacity of existing roof decks should be checked prior to installation.

* Usually where a second profiled sheet is placed over the insulation and mechanically fixed to the existing deck.
