Envirowall by Enviroflex is a cost-effective insulation designed for existing homes and renovations.
The Envirowall system is one of the most energy efficient insulation solutions, providing thermal benefits by creating a barrier for heat transfer in and out of your home.
Envirowall effectively fills the cavity between the internal plasterboard and external facade using a ‘blow-in’ technique, with minimal disruption to your home. It can be installed either externally through brick, brick veneer, double brick and weatherboard, or internally through plasterboard (where external restrictions apply).
Envirowall retrofit cavity insulation also provides acoustic improvements and can be used for internal walls to ensure noise does not carry between rooms
External walls should be insulated to reduce radiant, conducted and convected heat transfer.
Wall insulation can be installed:
Depending on the particular situation, some forms of insulation can double as a vapour or moisture barrier.
Most walls benefit from added insulation, and it is possible to add insulation to most construction types used in Australia. Autoclaved aerated concrete (AAC) already has a reasonable degree of insulation built into the blocks themselves, and straw bale is an extremely highly insulated system. Apart from these exceptions, added wall insulation is essential in all climates.
