A well-insulated and designed home provides year-round comfort, whilst saving you as much as 40% on your energy bills. This, in turn, reduces greenhouse gas emissions.

Insulation acts as a barrier to heat flow and is essential for keeping your home warm in winter and cool in summer. Insulation can also help with weatherproofing and eliminate moisture problems such as Condensation.


Roofs and ceilings work in conjunction to reduce the transfer of hot and cold energy. As much as 45% of your energy can be lost through this part of your home.

When evaluating your ceiling, we can also review the roof and provide insulation options to be installed directly under the tiles to reflect radiant heat.


Insulating your walls provides thermal benefits by creating a barrier for heat transfer in and out of your home, which can be as high as 25%.

We can provide a range of insulation solutions for walls, including thermal and acoustic batts and our exclusive Envirowall retrofit cavity wall insulation for existing homes.

Envirowall effectively fills the cavity between the internal plasterboard and external facade, with minimal disruption to your home.


Underfloor insulation keeps your floor at a constant temperature and prevents draughts. It is perfect for exposed floorboards on a suspended wooden floor.

It can be retrofitted to existing homes that have a subfloor and most new builds that have a requirement for floor insulation.

Not all houses are suitable for underfloor insulation, such as homes on a concrete slab where there is inadequate access.


Up to 25% of heat loss from existing homes is caused by draughts. Draught proofing identifies potential areas for air leakage and blocks them to make your home more comfortable and energy efficient.

We can review and install draught proofing solutions around your doors, windows and in particular wet area fans, with self-seal stoppers.


Our passion is our trade and our installer and sales teams have extensive experience working with builders to provide insulation installed to the highest quality standards.

We understand the challenges the industry faces and have a supportive, professional and problem solving attitude to all jobs.

Contact our team to discuss how we can supply and install quality insulation to the specification of your individual project/s.

Sustainability is at our core.

Enviroflex only use environmentally friendly insulation materials with high recycled content.
