Welcome to CJ Insulation Services Ltd., your UK distributor
for the Aval External Wall Insulation System.

System Description:

The External Thermal Insulation Composite System on your house is built up in layers.

c1  Beginning with your outside walls, your Atlas/AVAL approved contractor applies a primer to increase the adhesive properties.

c2  The second layer is an adhesive to bond the polystyrene insulation boards to your walls.

c3  To further ensure adhesion, the insulation boards are also mechanically fixed.

c4  A reinforcing layer consisting of two coats of a cementous polymer around a glass fibre mesh is added for strength and flexibility.

c5  Protective profiles are used on outside corners and movement joints.

c6  A purpose designed over cill provides a new window cill with graphite enhance polystyrene underneath where space permits.

c7  Finally, a topcoat of external render is added for a weather resistant finish.

Optionally, you may have a coat of paint added to the render or wish to have it painted in the future. AVAL acrylic render has excellent resistance to fading, chalking and yellowing and therefore tends to maintain its original appearance over time.
