Sealing the Future: How High-Density Spray Foam & Acrylic Coatings Rescued a Live Food-Grade Facility
High-density closed-cell spray foam + acrylic membrane coating on a fully operational Colorbond steel roof
At SprayIT Solutions, we specialise in
advanced insulation and protective roofing systems that deliver real performance for commercial and
industrial buildings. One of our standout projects in 2025 was the application of high-density
closed-cell spray foam to the external surfaces of a Colorbond steel roof on a major food packing
facility for SunRice Australia — all while the facility remained fully operational.
This wasn’t just a simple roof upgrade. It was a tailored
solution to address energy efficiency, staff comfort, ongoing operations, and long-term building
protection. We also finished the system with a flexible, UV-stable acrylic membrane to enhance
performance and durability.

Why Spray Foam + Acrylic
Coating Was the Right Choice
1Exceptional
Thermal Performance and Energy Savings
Closed-cell spray foam is one of the most effective insulation solutions available — delivering
high R-value per inch and creating a seamless thermal envelope over the entire roof
surface. This continuous layer dramatically slows heat transfer into and out of the building, reducing
the need for heating and cooling energy.
2Airtight,
Seamless Protection
Unlike traditional insulation or roofing membranes that rely on overlapping sheets or joins, spray foam
cures into a monolithic, seamless layer that conforms to every contour of the
roof surface. This eliminates gaps, seams, and weak points where air, heat or water can penetrate.
constant challenges.
3Superior
Moisture and Weather Defence
The high-density closed-cell structure acts as a moisture barrier, preventing
water ingress and significantly reducing the risk of condensation forming under the roof — a common
issue in metal buildings.
Adding the flexible
acrylic membrane on top provides an extra waterproof layer with UV resistance that:
- Protects the foam from sun
damage - Extends the life of the
roof system - Improves resistance to
wind, rain, and hail
4Increased
Structural Stability
Closed-cell spray foam doesn’t just insulate — it strengthens the roof
assembly. The rigid foam adheres tightly to the substrate and can enhance the structure’s
ability to resist uplift forces and dynamic loads such as wind or thermal expansion stresses.
Asset Protection
- Improved resistance to uplift forces
- Handles dynamic wind loads
- Reduces thermal expansion stress
Future-Ready
- Designed for foot traffic
- Allows ongoing roof access
- Low risk of failure in extreme weather
5Improved
Staff Comfort and Workplace Environment
By stabilising internal temperatures and reducing hot spots under the metal roof, spray foam
insulation significantly enhances indoor comfort for facility staff. This is
especially important in regions with hot summers or fluctuating conditions inside packing operations.
- Improved productivity
- Employee satisfaction
- More stable internal
environment for sensitive food-handling operations
6Minimal
Disruption — Business Continues
One of the standout benefits of this project was that SunRice operations continued
uninterrupted throughout installation. The spray foam is applied on the outside of
the roof span, meaning:

Facility Closures
0
Packing Disruptions
7Long-Term
Durability and Low Maintenance
Spray foam roofing systems that use a highly flexible specialised acrylic membrane over the spray foam
are known for their longevity — designed to last more than 20+ years.
spray foam roofing systems by combining UV resistance, reflectivity, flexibility, strong adhesion,
and durability. When used over closed-cell foam on an external roofline, it helps improve energy
efficiency, protect foam integrity, and prolong the life of the roofing system — all critical
benefits for commercial and industrial applications in Australia’s tough climate.
compatibility and longevity.
8Energy
Efficiency Is Sustainability
Reducing heating and cooling loads not only cuts costs; it also lowers the facility’s
carbon footprint. Spray foam’s airtight thermal barrier supports broader sustainability
goals by decreasing greenhouse gas emissions linked to HVAC energy use.
