Frequently Asked Retrofit Questions
Everything you need to know about roof vacuuming, thermal performance ratings, ISO compliance, Earthwool® batt fire classification, and indoor air quality.
Our technical assessors are available by phone to answer questions about ceiling access, solar panel clearances, or heritage timber roof structures.
Ask Our Technical TeamBrisbane sits in National Construction Code climate zone 2: warm, humid summers and mild winters. Most of the discomfort in a Brisbane home comes from above. Sun beats on the roof for hours, the roof space bakes, and that heat radiates down through the ceiling into bedrooms and living areas well into the evening. Good insulation, installed properly, slows that flow of heat and takes a big load off your air conditioner.

Insulation services for Brisbane homes
We handle every stage of an insulation upgrade, from clearing out what is already in the roof to fitting new product in ceilings, walls and floors.

Ceiling insulation
New Earthwool® ceiling batts are the single most effective upgrade for most Brisbane houses, cutting the heat that pours down from a hot roof space. Earthwool® uses ECOSE® Technology, a bio-based binder with no added formaldehyde, and is made with up to 80% recycled glass.

Insulation removal
Old batts that have compacted, been soaked by a storm leak or fouled by possums and rats no longer do their job. We extract them with a 25HP negative-pressure vacuum that feeds straight into sealed truck hoppers, so no dust comes into your living areas.
Learn more
Ceiling vacuums
A full ceiling vacuum clears loose-fill, dust, leaf litter, droppings and builders' debris from the roof cavity, leaving a clean base for new insulation.
Learn more
Blow-in insulation
Glasswool blow-in insulation reaches low-pitched roofs and tight eave edges where batts are hard to place, and replaces the old cellulose "fluff" found in many SEQ ceilings.
Learn more
Cavity wall insulation
Where a home has brick or block walls with an accessible cavity, insulation can be injected into the cavity to reduce heat moving through the walls, especially on west-facing sides.
Learn more
Underfloor insulation
Queenslanders and other raised timber homes lose warmth through the floor on winter mornings and let draughts in between the boards. Underfloor batts or spray foam fix that.
Learn more
Spray foam insulation
Closed-cell spray foam seals and insulates awkward areas such as subfloors, walls and the underside of roofs, adding an air barrier that suits humid conditions.

Insulation built for the Brisbane climate
Insulating a Brisbane home is a different job from insulating one in Melbourne or Hobart. Here the priority is heat gain. Dark roofs, west-facing rooms and low-set brick homes with little roof ventilation can turn into ovens on a February afternoon. Ceiling insulation, combined with good roof ventilation and reflective sarking where it exists, is the backbone of a cooler home.
Humidity matters too. Storm season brings heavy downpours and the occasional hail event, and a small roof leak can quietly soak batts for months. Wet insulation slumps, loses its performance and can encourage mould. Part of every assessment is checking the condition of what is already in your roof, not just measuring for new product.
Then there is Brisbane's housing mix. Character Queenslanders in suburbs such as Paddington, Red Hill and Wilston, post-war highset homes, 1970s and 1980s brick and tile houses, and newer estates on the city fringes all need slightly different approaches. We tailor the recommendation to the house in front of us.
