Proper insulation is not just about creating energy efficient homes.
There are wide-reaching benefits, spanning many policy areas.

Benefit Insulation

Health and Social

People spend a great proportion of their lives in buildings. Insulation provides more than energy efficiency. Thermal and acoustic insulation play important roles in improving the quality of life by providing environments that are more comfortable – this leads to greater productivity at work.
Studies show that well insulated buildings provide a healthier environment by controlling temperature and noise levels.
By reducing household and business running costs, energy saving from insulation can provide a buffer to other cost-of-living increases.
Insulation protects and improves the quality of life for the elderly and socially disadvantaged.


Insulation reduces average home heating and cooling costs by around 30%.
Insulation reduces the burden of increasing energy prices.
The cost of installing insulation pays for itself in around 3-5 years through reduced energy bills, and payback time will improve as energy costs rise over time.
The right insulation is a once only cost that last for the life of the building (typically 50-70 years) and requires no further maintenance.
Insulation improves property values and has been shown to increase the return on rented and leased properties.
Insulation is not expensive. To insulate the ceilings and walls of a typical house costs less than 1% of the total construction cost.

Load and Demand

Insulated buildings reduce the need for additional power generation capacity by ‘smoothing out’ the peaks in energy demand.
Well-insulated homes have a reduced need for air-conditioning.


Glasswool is manufactured from up to 80% recycled glass content, derived from 100% recycled post-consumer glass used beverage containers (UBC), and waste flat glass, depending on availability.
In addition, glasswool plants recycle all water used in the manufacturing process and glasswool insulation uses no ozone depleting products (ODP) in manufacture, are low allergen, and have low embodied energy. Glasswool is amongst the world’s most sustainable building products
