Types of Insulation We Install

Polyester insulation is typically made from recycled materials, so it also has eco-friendly credentials. It doesn’t offer the same thermal performance as glass wool insulation, but it is still an effective choice for keeping your home warm. Also, unlike glass wool insulation, chemicals are not used to manufacture polyester insulation. Polyester insulation won’t cause irritation if you come into contact with it and it doesn’t produce breathable fibres, making it a good choice if you have allergies. It can be a bit trickier to install as it is not as easy to cut as glass wool insulation.

Glass wool insulation, also known as fibreglass insulation, is one of the most common types of insulation used in New Zealand homes. It is made from recycled glass so helps the environment by re-using a waste material. It is also a high performing insulation, delivering excellent thermal performance, and it is non-combustible. The cons include the fact that chemicals are often used to bond the materials, while glass fibres can cause irritation to the skin or eyes if you come into contact with them.
