The easiest way to retrofit roof insulation

Loft blown insulation fills the spaces around trusses, wires, pipes and odd-shaped cavities — a complete thermal blanket for your ceiling, at an affordable installed price.

Why the roof matters

Over 30% of your heating costs can escape through the roof

Warm air rises. Without good ceiling insulation, the warmth you pay for collects at the ceiling, passes into the roof space and disappears outside — while your heater works overtime.

In summer the same physics works against you: the roof space heats up and radiates heat back into your rooms. A properly insulated ceiling is the single most effective upgrade for most homes.

Blown roof insulation

Where Loft Insulation is used

Superior coverage compared to batts or blankets — no joints, gaps or thermal bridging.
Open roof cavity

Open roofs & attics

Blown into open roof cavities for complete coverage and high thermal performance — ideal for most existing Waikato homes.
Ceiling insulation

Floors & midfloors

Perfect where access is limited, or where you want to cut noise travelling between floors as well as heat loss.
