Loft Insulation is the ideal solution to efficiently and properly insulate ceiling, floor & mid-floor spaces. Installers work quickly because blown-in insulation fills the spaces around trusses, wires, pipes and irregular-shaped cavities, creating a complete thermal barrier for your home.

It is also a perfect option when you want a high-performance insulation product at an affordable installed price, giving you a practical way to upgrade your home without unnecessary cost.

Benefits of Loft Insulation

Loft Insulation helps homes stay warmer in winter and cooler in summer by delivering strong thermal performance across roof and ceiling insulation spaces. Because installers blow the insulation into place, it fills gaps easily and creates consistent coverage. As a result, homes hold temperature more efficiently and reduce heating and cooling energy use.

At the same time, Loft blown roof insulation helps absorb sound within construction cavities, reducing noise transfer and creating quieter living spaces. Accredited installers can also complete installation quickly, making it a practical option for both retrofit and new build projects across New Zealand.

In addition, Loft Insulation supports environmentally responsible building choices, as the product uses up to 80 percent recycled glass content. Together, these benefits make Loft a high performance insulation solution for modern NZ homes.

Why is roof insulation so important?

Did you know that over 30% of your home’s heating costs can come from poor or missing insulation? The same can apply to more than 30% of your cooling costs as well.

Once you understand how heat moves, this makes sense. Warm air naturally rises, while cooler air drops. This simple physics has a big impact on how your home performs.

When you heat a room, warm air rises and collects near the ceiling. Without insulation, that warmth transfers through the ceiling into the roof space and eventually outside. As the room loses heat, cooler air drops back down, creating a cycle where warm air keeps rising and escaping. As a result, your heating system works harder and costs more to run.

Likewise, cooling a room creates the opposite challenge. During hot days, the roof space heats up quickly. Because roofs have limited airflow, hot air builds up and warms everything it touches, including the ceiling. The ceiling then radiates heat back into the room. Meanwhile, most fixed air conditioning units sit high on the wall, exactly where warmer air collects. This forces the system to cool air that is already hotter than the rest of the room.

In addition, the temperature sensor in the unit measures air at wall height rather than floor level. As a result, the system can overcool the space, which increases energy use unnecessarily.

When you combine these effects, a significant portion of both heating and cooling costs can escape through an uninsulated roof space.

That’s why ceiling insulation plays such an important role in improving comfort and reducing energy use. Talk to one of our friendly loft insulation resellers to find out how you can insulate your ceiling and improve the performance of your home.

Why choose Loft blown roof insulation?

Quite simply Loft ceiling insulation works to keep the outside temperature out and the inside temperature in! Think of it like a lid on a chilly bin or vacuum flask, if you put hot food in it stays warm and if you put cold food in it stays cold. It works to stop/slow temperature transfer. The better the insulation grade or type of insulation product you use the less temperature transfer there is, so the better the insulation works. Inadequate ceiling insulation and air leakage are leading causes of energy waste in most homes.

Correctly designed & fitted insulation:

  1. Saves money and our nation’s limited energy resources
  2. Makes your house more comfortable by helping to maintain a uniform temperature throughout the house
  3. Ceilings warmer in the winter and cooler in the summer.

Poorly insulated homes are usually cold & damp, with occupants crowded over a heater in one area to keep warm. Homes insulated with the full proven systems like Loft use similar amounts of energy to keep your whole home at a healthy, comfortable temperature.

How good is Loft Insulation?

Loft is a premium insulation produt, and one of the best insulation products available allowing you to keep the outside temperature our and the inside temperature in!

The total installed thermal roofing insulation effectiveness of Loft is superior to batting or blanket, as it covers the full ceiling – without joints, gaps, thermal bridging, or vented cavities commonly found between linings and batting or blanket insulation. It provides premier insulation values. Batting insulation or blanket materials need at least two layers to achieve the same installed thermal effectiveness of Loft insulation.

Old insulation removal may be necessary before new Loft insulation is installed eg insulfluf removal. Talk to us today about installing Loft insulation into your roof or attic.
