At Castleforms we pride ourselves in manufacturing and supplying high quality insulated foundation systems.

 

 

Raft Therm

Raft Therm is an insulated foundation system used in the construction of residential & commercial buildings. Reduced cold bridging and exceptional U values as low as 0.1wW/m²K are achieved by wrapping the sides and underneath of the concrete foundation and ground floor in a continuous layer of high density expanded Polystyrene.

Raft Therm components are pre-formed in our factory requiring minimal preparation on site.  Each Insulated Raft is specially designed according to the client's specification and requirements.These insulated foundation systems are suitable for use in conjunction with various wall types including masonry, timber frame, light gauge steel and ICF.

 

Swift Therm

Swift Therm is an advanced sub-structure system that combines the fast construction and insulation of :

  • The external and internal sub structure walls.
  • The ground floor slab and perimeter.

The panels are secured in position using a combinations of plastic and metal fixings, reinforcing steel bars if required are clocked into these same fixings. The lightweight nature of the system allows for fast assembly with the height and width of the walls panels easily adjusted to suit each application. The system is compatible with multiple wall types such as masonry, timber-frame and light gauge steel.
