Insultec
The Original Brooks Liquid Insulation Paint — trusted by Australian homeowners and commercial contractors since 2004.
Insultec's patented ceramic microsphere formula creates a highly reflective barrier that blocks solar radiation and dramatically reduces surface temperatures. Applied in one or two coats over a prepared surface, it creates a durable, weather-resistant membrane that lasts for decades.
- Reduces roof surface temperatures by up to 15°C
- Suitable for metal, tile, fibro, slate, Colorbond & more
- Impervious to salt spray and water permeability
- Mould, fungus and algae resistant membrane
- Standard 10% acid & alkali solution resistant
- Eco-friendly water-based formula — zero harmful emissions
- In use for 20+ years — proven long-term durability

Product Overview
Insultec is a revolutionary liquid insulation coating that uses a unique combination of ceramic microspheres, hollow glass beads, and reflective pigments to block, reflect, and dissipate solar radiation before it penetrates your building envelope.
Unlike traditional bulk insulation, Insultec works as a barrier directly on the roof surface — the source of heat transfer — making it significantly more effective at preventing heat gain during summer months.
The membrane which is the vehicle for the special heat-rejecting fillers has been in constant use for more than 20 years, proving its durability and long-term performance in Australia's most demanding climates.
Key Performance Benefits
Heat Reduction
Up to 15°C cooler surface temperatures
Waterproof
Impervious to rain and moisture penetration
Chemical Resistant
10% acid & alkali solution resistant
Anti-Microbial
Resists mould, algae and fungal growth
Application Instructions
Step 1 — Surface Preparation
Proper preparation is critical to achieving maximum adhesion and long-term performance.
- → Wire brush or scrape away surface dirt, loose paint, and fungal growth
- → Treat mould/mildew with a 10% solution of Acticide fungicide
- → Repair surface cracks and carry out any necessary structural repairs
- → Gloss surfaces must be sanded to break up the gloss finish
Step 2 — Apply Insulprime
Apply one full coat of Insulprime primer to the prepared surface. Allow to dry completely before proceeding to Step 3.
Step 3 — Apply Insultec
Apply one or two coats of Insultec by brush, roller, or spray. Allow each coat to cure fully (2–4 hours) before applying the next.
Application Methods
Brush
Ideal for edges and detail work
Roller
Best for flat, open surfaces
Airless Spray
Fastest for large areas
Pro Tip
On particularly bad or porous surfaces, it may be necessary to apply three coats for optimal thermal performance and full membrane integrity.
Compatible Surfaces
Colorbond
Apply Insulprime first, then Insultec
Masonry

Excluding terracotta tiles
Metal
Zinc phosphate primer required first
Bitumen
Non-bleeding asphalt & pitch surfaces
Painted Surfaces
Must be sound and well-bonded
Timber
Prime with wood primer first
Not Terracotta
