Blown-in Wall Insulation for a Warmer Home
Most older Southland homes have little to no wall insulation, which means heat escapes through the largest surface area of your home. Wall insulation can make one of the biggest differences to warmth, comfort, and energy efficiency. At Awarua Synergy, we now offer blown-in wall insulation, meaning you can now insulate your walls without major renovations.
Why Wall Insulation Matters
- Walls lose 20–30% of total heat
- Stabilises indoor temperature
- Reduces condensation and dampness
- Improves heat pump performance
- Makes older homes feel significantly warmer

We've Partnered With Safe-R to Offer CosyWall Blown-In Wall Insulation
To bring Southland homeowners the very best wall insulation solutions, we’ve partnered with Safe-R to offer CosyWall, one of New Zealand’s leading blown wall insulation systems. This partnership allows us to provide a high-performance, proven product that can be installed into existing homes with minimal disruption. CosyWall has been engineered specifically for New Zealand conditions, making it ideal for the cold, damp climate of the Deep South. By working with Safe-R, we can ensure every installation is completed to the highest standard — giving you warmer walls, a more comfortable home, and long-lasting energy savings.
How Blown Wall Insulation Works
Small holes are drilled into the exterior or interior linings, insulation is blown into the cavity, and the holes are sealed. The process is quick, tidy, and creates a fully insulated wall system — without removing plasterboard.
CosyWall can be installed into existing homes with:
- Brick
- Weatherboard
- Fibre cement
- Stucco
This makes it a game-changing option for many Southland houses.
