Spray Foam Insulation Specialists
While insulation batts are often the best choice for standard ceilings, spray foam insulation excels where traditional materials fall short. At Proshield Insulation, we recommend spray foam for a range of specialised applications, including:
- Older, draft-prone homes
Provides insulation for subfloors and hard-to-reach cavities where air leaks are common and indoor comfort is compromised.
- Sheds and garages
Provides improved temperature control and dust reduction without major renovations.
- Caravans, campervans and boats
Provides a lightweight, space-efficient solution with insulation, moisture resistance and noise reduction for life on the move.
- Shipping containers and workshops
Transforms metal structures into usable, temperature-stable environments by sealing gaps and preventing condensation.
- Hot warehouses and industrial spaces
Helps regulate extreme internal temperatures, reducing heat load, improving working conditions and lowering cooling costs.
- Asbestos encapsulation projects
Provides a cost-effective alternative to removal when combined with waterproofing, sealing over existing asbestos in older warehouses and industrial spaces to improve safety and usability.
Smarter insulation for warmer, drier living.
The Smarter Way to Insulate: Spray Foam Insulation
When it comes to insulation, spray foam offers a smarter, more versatile solution for spaces that batts simply can’t handle. Unlike traditional batts, which can sag, shift or attract pests over time, spray foam insulation expands to fill every gap and bond directly to the surface it’s applied to. This creates an airtight, waterproof seal that improves comfort, reduces energy costs and protects your home or workspace from moisture, drafts and unwanted noise.
While batts are often the better choice for standard ceiling insulation, spray foam truly shines in areas where other materials fail—especially in subfloors, sheds, shipping containers and even vehicles. Its flexibility and superior sealing power make it the go-to option for tough or irregular spaces.

What We Do
Spray Foam Insulation
Discover how spray foam creates an airtight, waterproof seal that outperforms traditional batts. Ideal for subfloors, sheds, vans and containers needing energy efficiency and moisture protection.
Insulation
Enhance comfort and reduce energy costs with tailored insulation solutions for homes, sheds, caravans, and marine spaces. Protect against drafts, damp and noise for long-term performance.
Where Spray Foam Excels
Underfloor Insulation
Subfloors are one of the toughest areas to keep insulated. Batts tend to fall out over time and often become a haven for pests like rats and insects. Spray foam insulation completely seals the underside of your floor, blocking drafts and helping prevent rising damp. Its waterproof nature also adds a layer of protection against ground moisture — keeping your floors warmer, drier and longer-lasting.
Work Sheds & Garages
Spray foam bonds directly to metal, making it perfect for sheds and garages constructed from Colorbond or steel. It fills the grooves in the metal panels, eliminating air pockets where condensation usually forms. There’s no need to install lining over the insulation — spray foam delivers a clean, seamless finish that both insulates and prevents moisture build-up.
Caravans, Vans & Tiny Homes
Transforming your van or building a tiny home? Spray foam is ideal for hard-to-reach or oddly shaped areas where batts simply don’t fit. It provides exceptional thermal and acoustic insulation, keeping your mobile space comfortable in all weather conditions.
Shipping Containers
Shipping containers are notoriously difficult to insulate due to their ridged surfaces and trapped air pockets. Spray foam adheres tightly to the metal walls, filling every groove for a smooth, insulated surface. The result is a more comfortable, condensation-free interior that’s ready for living, working or storage.
Marine Applications & Soundproofing
For boats and marinas, spray foam provides both soundproofing and waterproofing benefits. It fills internal cavities to reduce engine noise and vibration while acting as a moisture barrier to help prevent rust and corrosion. A practical and protective solution for marine environments.
Asbestos Protection
A cost-effective alternative to removal when paired with waterproofing, spray foam seals over existing asbestos in older warehouses and industrial spaces. It helps improve safety and usability by encapsulating ageing surfaces, reducing disturbance and enhancing moisture control without requiring full material removal.
Hot Warehouses & Industrial Spaces
Spray foam insulation helps regulate extreme internal temperatures, reducing heat load, improving working conditions and lowering cooling costs. By limiting heat transfer through roofs and walls, it creates a more stable internal environment, making large industrial spaces more comfortable and efficient to operate.
Built-In Waterproof Protection
One of the biggest advantages of spray foam insulation is its natural waterproofing ability. Once applied, the foam forms a continuous barrier that stops water from seeping through walls, floors, or subfloors. This makes it an ideal choice for areas prone to damp, humidity or condensation. By sealing gaps and cracks, spray foam helps protect your home or workspace from mould, mildew and structural damage caused by moisture — keeping your space dry and protected year-round.
Safe, Professional Installation
Proshield uses only high-quality, certified spray foam products that are safe once cured. Our professional installers apply the foam using specialised equipment, ensuring precise coverage and correct thickness for maximum performance. During application, the area is safely ventilated, and once the foam sets, it becomes completely inert and non-toxic. The result is a durable, long-lasting insulation layer that’s safe for your family, your property and the environment.
Environmentally Smart Installation
Spray foam insulation isn’t just effective — it’s energy smart. By sealing every gap and preventing air leaks, it significantly reduces heating and cooling loss, meaning your home or workspace uses less energy to stay comfortable all year round. This improved thermal efficiency helps lower power bills and reduces your carbon footprint. With spray foam insulation, properties can achieve higher energy efficiency star ratings, making it a smart investment for both the environment and your long-term savings.
