Declare - Label - MammothMammoth™ have two wall insulation formats to help create a warmer, drier environments – pads and blanket.

Pads are semi-rigid polyester insulation that is friction fitted between studs. Mammoth air-lay wall sections are self-supporting and contribute to a superior installation without gaps, creases, folds or compression.

Blanket rolls are lofted polyester insulation that is stapled to the top dwang to fit snugly between wall studs.  Mammoth Wall Blanket insulation is available in R2.2 and R2.6.

Designed to work in conjunction with the building systems of existing and new homes, Mammoth Wall insulation provides effective, durable and reliable insulation that you can be assured works for at least 50 years*

Mammoth Wall Sections are available in R2.0 and R2.5 as well as specialised masonry wall sections.  Masonry wall insulation is a high density insulation for masonry lined homes within a frame or strapping system to increase thermal performance.
