Insultech’s experience in the residential energy efficiency industry is second to none in New Zealand. The company was established in Auckland in 1990 by two partners with combined experience in insulation of over 20 years, to address the causes of New Zealand’s cold, damp houses. Since then, the company has developed a range of insulation systems by working with major international insulation manufacturers for new or existing home floor, wall and roof insulation and other associated home energy efficient measures. 

Insultech Insulation specialises in existing wall insulation. Our dry fibre system uses CosyWall, a mineral wool manufacturered in the USA. CozyWall is formaldehyde free and will not shrink. Cosy Wall is installed via the internal or external linings via a 28mm hole. Our CosyWall system includes reinstatement of the cladding. Call now for you free home comfort assessment.
