What are the thermal benefits?

Cedral Weatherboard, when used with insulation, provides excellent levels of thermal performance.

Providing thermal insulation for walls

Rainscreen Cladding is a relatively high-benefit, low-cost method of providing thermal insulation to external walls for both refurb (overclad) and new build projects.

Adding insulation to the external surface of the loadbearing structure has three key benefits: -

* Increased thermal efficiency - dependent on the fixing system used.  Up to 240mm of insulation can be added using a Marley Eternit framing system

* No loss of internal space - insulation added to wall cavities or inner leaf inevitably consumes internal habitable space

* Light weight and easy to fix - insulation can be rapidly and easily fixed to the exterior substrate and adds very little loading to the rainscreen system
