Insulation – Network Building Supplies


Proper insulation makes a significant difference in the energy efficiency and comfort of a property. The right insulation choice allows the occupants of a building to have a comfortable environment, no matter what the climate is.

Insulation materials are often made of wool, fibreglass, cellulose, natural fibres, foam boards or sleek foils. 

Why is insulation important?

Considered one of the most important building features, insulation helps save money on heating and cooling. It also prevents condensation, the rotting of building materials and the formation of mould, all of which reduces the risk of insurance claims and future problems.

With the right insulation system in place, you can also maximise your investment of eco-friendly sources of energy such as solar panels and heat pumps.
