Up to 25% of your heat can be lost through the walls in an uninsulated home. Adequate, quality wall insulation is a critical component in the thermal envelope of your home. Many of New Zealand's cold, damp homes are due to little or no insulation in the ceilings, floors and walls.
Wall insulation is mandatory in all new homes and yet, hidden behind wall board, it doesn't always get full consideration. Your choices about insulation for your walls will have a big impact on your home's long-term comfort in summer and winter.
Our wall insulation range includes options for both 90mm and 140mm wall cavities as well as acoustic insulation products designed for internal walls (around bathrooms, bedrooms & TV areas) and mid-floor insulation.

NOTE: Smart Energy Solutions does not offer a blow-in or foam wall insulation solution for walls.
The minimum thermal resistance (R-Value) of new wall building systems is R1.9 other than in the South Island and the Central Plateau whether climate conditions require an R-Value of 2.0
There are three main options for retrofitting wall insulation into existing homes. All these options for wall insulation retrofitting require a building consent due to the complexity of the work and the potential ramifications on the overall building envelope.
Smart Energy Solutions does not retrofit wall insulation unless it is a major consented renovation where you are removing or replacing the wall board.
Injected insulation foams or blown-in loose insulation requires holes to be made into each individual wall cavity to inject/blow-in the insulation. A single wall may have 9 - 16 or more individual cavities.
The risks come if the hole is drilled from the outside as watertightness may be compromised. The Energywise website states "it creates a higher risk to the weathertightness of the cladding and damages the wall underlay".
Injecting from the inside creates less risk but does require some redecoration to cover the drill holes.
Very respectful, nice employees, answered all my questions concerning insulation. Very prompt and efficient.
