Question or Comment:

Key Insulation has insulation solutions for homes, offices and commercial buildings in and around Wellington.

Key Insulation Ltd specialises in retrofitting existing walls, inaccessable flat and sloping roof ceilings in the Wellington region, and now the Christchurch region. Many New Zealand homes were built with little if any regard to insulation and the benefits of insulating your home or building are immediate and effective.

The process has evolved from our experienced plastering and interior decorating background and offers a cost effective solution as an alternative to full strip and refit of walls or ceilings.

Scotias, architraves skirtings and floor coverings are not disturbed, saving additional costs in refinishing these areas if not required.

Why insulate?

  • Increased comfort, thermal performance and health benefits.

  • Reduces energy costs of heating and cooling.

  • Improves sound proofing and accoustic properties .

Which insulation?

For walls we use and recommend Novatherm Multi, a semi rigid Polyester Dacron material manufactured especially for insulation. Novatherm Multi has no irritants, is toxin and dust free, and carries a 50 year guarantee against deterioration of loft and R value.
