Cavity / Internal Wall Insulation
Insulation inside the wall build-up — boards in the cavity or behind the lining that quietly stop heat at the wall line.
One System, Built to Work Together.
Where facades can't change, the insulation goes inside: rigid boards in the cavity between leaves, or fixed to the inner face behind plasterboard and plaster.
EPS and XPS boards cut cleanly and fit tightly between wall ties and framing, upgrading thermal comfort room by room or across whole projects.

- 03
Inner Leaf
The internal structural skin of the wall.

Internal Finish
Plaster or lined finish completes the room side.
01Comfort Without Facade Works
Upgrade thermal performance with no scaffolding and no change to the elevation.
02Quieter Rooms
Insulated cavities damp airborne noise between outside and in.
03Condensation Control
Warm inner surfaces stop damp patches and mould at cold spots.
04Cut-to-Fit Simplicity
Boards trim with a blade and fit tight between ties, studs and services.
