The combined thermal resistance of a solid wall construction without a cavity is estimated to be between R0.3 to R0.4. This is insufficient for most building code compliance or sustainability requirements and for this reason, additional bulk insulation is is generally specified at the design stage.
An R-value of R1.5 is generally considered to be the minimum requirement in a new home, and many homes will be specified as requiring a higher R-value. If the frame of the house is not wrapped with Sisalation or a similar wall wrap product, it can be a challenge to install the relatively thin (e.g. 75mm) R1.5 insulation batts between the vertical wall studs, without the insulation sagging and coming into contact with the bricks or external wall lining. It's always recommended to maintain an air-gap between the internal and external walls. On this front, Pink Bats wall insulation has an edge over some of its competitors - they are pre-stiffened, and easy to install between the wall studs.
Thanks to advances in formulation, Pink Batts are now low itch - making them more comfortable to handle during installation. Pink Batts® are a trusted choice when it comes to constructing new homes or retrofitting existing buildings for increased thermal efficiency.
