    Fiberglass Insulation

    Fiberglass insulation is very much the traditional mainstay of insulation in NZ. It is a very popular product both here and around the world and is used in both new and older homes. Fiberglass insulation is manufactured from glass and usually contains as much as 80% recycled glass. The following are some advantages and disadvantages of fiberglass insulation.


    • An economical option.

    • Achieves a higher thermal performance level by thickness than other materials meaning it can often be fitted into tighter spots than other products.

    • Is easy to work with when installing as it can easily be cut and manipulated around fixtures in the ceiling such as downlights, fans etc.

    • Bales can be tightly wrapped and compressed making them easier to move into the attic space.


    • The fibers are small enough to create irritation of the skin and respiratory system during installation.

    • Protective clothing and light respiratory equipment (i.e. a dust mask) must be used when handling.

    • Can tend to become damaged if moved or walked on too many times.

    • Is not as suitable for use in subfloors.

    When we visit your home we will happily show you samples of our fiberglass insulation products.
