How does insulation work?
Insulation serves as a barrier against both heat loss and uptake. This is critical in ceilings, roofs, and walls. Insulation is classified into two types in general. Bulk insulation that acts as a barrier to keep heat in or out. Reflective insulation deflects radiant heat, keeping your home cool throughout the summer.
What's different about insulating in Tasmania?
Obviously, in Tasmania, the majority of our insulation efforts centre around keeping the cold out of your home and maintaining the heat you currently have inside. If you can maintain the warmth within your house rather of losing it through the walls, ceiling, or roof, you will require less energy to heat it. That means you’ll save money on your energy costs and help the environment!
What insulation do I need if my home is too hot in Summer?
When the weather is warm, the motivation to insulate turns to keeping the heat out of your home while preserving the cold air already inside, or to enhance the efficiency of cooling systems and so minimise operating expenses. So, once again, limiting energy consumption means lowering your energy costs and lessening your environmental effect!
Where does my home lost most of it's heat?
Each home will be different in where it loses most of it’s heat. Our free quote helps work out where your home needs improving in the area of insulation. Give us a call today and we can identify what’s going on in your home.

We've had Allen from Retro-Spec Insulation perform two insulation jobs for us and both times the results were nothing short of spectacular. In both cases it took the houses from being miserably cold in the winter to being quite pleasant to live in.
The value of wall insulation is completely underrated in Tasmania. In places like Queensland where you are trying to stop solar gain, ceiling insulation is important and walls less so, but in Tasmania where where heat loss from the structure during winter the dominant energy user, wall insulation is just as important as having the ceiling insulated.
Allen and his team do an amazing job of installing pumped wall insulation using minimally invasive techniques, so you don't have to wait until the next renovation to add insulation to your house.
