Superstructure specifications.

SIP superstructure

Our panellised system is made from 12mm cement bonded particle board and a profiled metal perimeter to enable panel-to-panel connections. The panels are filled with 160mm blown PU foam insulation that bonds the entire panel together and gives it its high structural strength, airtightness, and low U-value of 0.13w/sqm.


Partition walls

Separating walls (party walls)
The same panels as the exterior are used to create party walls, due to their fire-resistance, strength, and acoustic performance properties. They are thinner than traditional party walls, allowing for increased GIFA.

Partition walls (walls within the dwelling)
Typically timber frame construction (89×38 CLS).

Exterior finishes

Any style of exterior finish can be applied to our panel superstructure.


We provide intermediate floors as a metal web joist floor cassette, as standard. But we can also use beam and block or pre-cast concrete floors.


We can deliver any roof type to meet design requirements, including pitched and flat roofs.
