Wall Insulation
Exterior Wall
Our exterior wall insulation is dense, rigid and resilient to slumping. Supplied in standard widths designed to fit between studs spaced at 600mm or 400mm and lengths designed to fit a 2.4m to 2.7m stud height. If stud spacings are variable we can manufacture specific widths.
Service Cavity
Using timber battens installed perpendicular to studs creates a service Service Cavity for plumbing and cabling. While allowing the primary insulation layer to remain uncompromised, it also greatly reduces the thermal bridging area of timbers in exterior walls and provides a further layer of insulation to raise the total R-Value.
Acoustic Interior Wall
CHATTERBLOCK® is our default thermal insulation for interior walls. It provides a strong sound barrier between walls, thanks to wool’s remarkable sound-dampening qualities, as well as excellent thermal insulator properties.
