Loft Open Roof Insulation
What is Loft Insulation?
Loft insulation is a blown, un-bonded glasswool product designed to fill ceiling cavities and create a complete thermal barrier. It can be installed in both new builds and existing homes to improve comfort and energy efficiency.
Benefits
Loft insulation offers exceptional thermal performance by filling every gap and void in a roof cavity, helping your home stay warmer in winter and cooler in summer. Because it is blown into place, it forms a continuous and consistent thermal layer that outperforms traditional blanket or segment insulation.
This complete coverage makes loft insulation ideal for achieving high installed R-values and meeting New Zealand’s updated H1 insulation standards. It can be used as a standalone solution or added as a top-up layer to improve the performance of existing insulation.
Alongside thermal benefits, loft insulation provides strong acoustic performance. It helps absorb sound and reduces noise transfer between rooms and from outside, improving comfort and privacy within the home.
Loft insulation is also an environmentally responsible choice, made from up to 80 percent recycled post-consumer glass. Installation is quick and tidy when completed by accredited installers, ensuring a high-quality finish and reliable long-term performance.
Improved Energy Efficiency
Loft insulation helps regulate indoor temperatures by reducing heat loss through the ceiling. This lowers energy use, saving you money on heating and cooling.
Improved Indoor
Air Quality
A well-insulated ceiling reduces draughts and helps maintain a drier, healthier indoor environment by preventing warm air from escaping into the roof space.
High Thermal Performance
Loft Insulation delivers excellent installed R-values, filling every gap and void to create a continuous thermal barrier that outperforms traditional blanket insulation.
