Why insulate your home?
Hamilton winters are cold, damp and foggy — and most older Waikato homes were built with little or no insulation. Good insulation is the difference between a home that fights you all winter and one that looks after you.

Your home’s thermal barrier
Think of insulation as a lid on a chilly bin: it slows the transfer of temperature, keeping warmth in through winter and heat out through summer.
Heating and cooling account for a big share of the energy used in an average home. In an uninsulated house that energy leaks away constantly — roughly a third through the roof, up to a quarter through the walls, and more through the floor and draughts.
A complete thermal barrier — ceiling, walls and floor — is what turns a cold, damp house into a warm, dry, healthy home.
Where the heat goes
Typical heat loss from an uninsulated New Zealand home — and the fix for each.
30–35%
Through the roof
Warm air rises and escapes through an uninsulated ceiling — the single biggest loss in most homes.
~25%
Through the walls
Pre-1990s homes usually have completely empty walls — the most overlooked gap in the barrier.
12–14%
Through the floor
Suspended timber floors let heat drain away and draughts creep in underneath.

What good insulation does for you
-
A healthier home. Warm, dry rooms mean less condensation, damp and mould — and fewer winter illnesses.
-
Lower power bills. Keep the heat you pay for instead of pumping it into the sky.
-
Even comfort, all year. A uniform temperature through the whole house — warmer winters, cooler summers.
-
A more valuable home. A warm, dry, well-performing home appeals to buyers and tenants alike.
Common questions
Why is blown insulation better than batts?
Batts have to be cut and fitted, which leaves gaps around pipes, wires and odd-shaped cavities — and gaps leak heat. Blown insulation fills every nook at controlled densities, so there are no joints, gaps or thermal bridging.
Is it safe?
Yes. Our products are non-combustible glasswool made with up to 80% recycled glass, and we fit XLP protectors around recessed downlights. Completely safe for your family, with a life expectancy of over 50 years.
Do I have to insulate my rental property?
Yes — the Healthy Homes Standards require rental properties to have ceiling and underfloor insulation where it can practically be installed. We work with Waikato landlords and property managers to get rentals compliant quickly.
How disruptive is the install?
Far less than you’d think. Most homes are done in about a day, wall insulation goes in without removing linings, and we tidy up after ourselves — you’d hardly know we’d been, except the house is warmer.
How much will it cost?
Every home is different, so we start with a free, no-obligation assessment and give you a clear fixed quote — no surprises.
