Experience year-round comfort

Safe for your family, GreenStuf® keeps your home warmer, healthier, and drier all year-round.

Insulation made for Kiwis by Kiwis

A well insulated home provides year-round comfort; it is cooler in the summer and warmer in the winter. Around 35% of the energy used in the average New Zealand household goes towards heating. Without adequate insulation your energy spend is wasted, as heat escapes through the walls, ceilings, and floors.

Is your home sufficiently insulated?

A properly insulated house is the first step towards a warmer, healthier, more comfortable home for you and your family. Here is a quick guide for checking whether your insulation is satisfactory.

Ceiling insulation

Grab a step ladder andhave a look around your roof/attic space. Is there insulation? If not, you need to get some! If yes, let’s check to make sure it is up to standard. Getting the best out of your ceiling insulation can be quite the science - especially if you have downlights - so please contact us if you are unsure.

You will need an extra layer of insulation if:

Insulation is 12cm thick of less.

Insulation doesn’t cover the whole ceiling.

Insulation has gaps in it, or places where it is squashed or tucked in.

Insulation is old.

You will need to remove the old insulation and replace it if:

Insulation is wet or damp in areas.

Insulation is damaged by rodents or birds.

Underfloor insulation

If it’s possible to access your underfloor, checkfor insulation. Insulation will either be in-between, or stapled to, the underside of the joists. If not, you need to get some! If yes, let’s check to make sure it’s up to standard.

You will need an extra layer of insulation if:

Insulation is loose or doesnt sit hard against the underside of the floorboards.

Insulation doesn’t extend under.

the entire floor space.

Insulation has gaps in it or has bits missing.

Insulation is foil.

Insulation has been damaged.
