SIP Panels Adelaide — Structural Insulated Panels for Coolrooms & Modular Housing
Commercial-grade EPS structural insulated panels supplied from Adelaide. High R-value, fast to build, engineered for Australia's climate. Trusted by coolroom contractors, container home builders, and modular housing fabricators.
What Are SIP Panels?
Structural Insulated Panels (SIPs) are high-performance building panels used in walls, roofs, and floors. An EPS (expanded polystyrene) foam core is bonded between two structural facing layers — creating a strong, thermally efficient sandwich that outperforms conventional timber framing on almost every metric.
At Cool Room Master, we supply the same commercial-grade EPS insulated panels used in our coolroom systems — now available to builders, designers, and owner-builders tackling modular homes, container conversions, and prefab construction across South Australia and beyond.
"We build coolrooms. And cool rooms."
Coolroom panels for cold storage. The same panel technology for modern modular housing. One product. Two industries. Zero compromise.

Where SIP Panels Are Used
Our EPS panels serve two distinct markets — commercial cold storage and residential/modular construction. The same panel. Different applications.
🧊 Commercial Coolrooms
Walk-in coolrooms, freezer rooms, and refrigerated storage facilities. 50mm and 75mm panels for optimal cold retention. Our original application — and still our core business.
🏠 Container Home Conversions
Insulating shipping containers with EPS SIP lining dramatically improves thermal performance. Increasingly popular for off-grid homes, remote accommodation, and affordable housing projects.
🏗️ Modular & Prefab Housing
SIP panels for modular home manufacturers, granny flat builders, and prefab housing contractors. SIP construction cuts build time significantly vs traditional timber framing.
🌿 Garden Studios & Home Offices
Backyard studios and home offices built with SIP panels are faster to construct, quieter, and far better insulated than timber-framed equivalents. Ideal for Adelaide's harsh summers.
🌾 Agricultural & Rural Buildings
Produce storage, farm cool stores, and rural machinery sheds. EPS panels are lightweight, durable, and require no painting, sealing, or ongoing maintenance.
🏛️ Government & Crisis Housing
Fast-deploy temporary or permanent housing using panel systems. Australia's housing shortage is driving demand for SIP-based construction — and Cool Room Master is ready to supply.

Why Source SIP Panels from Cool Room Master?
We've supplied EPS panels to South Australian businesses for years. Here's what separates our panels from generic building supply options.
Commercial-Grade Quality
The same panels used in commercial coolroom construction — not entry-level building products repurposed for the housing market.
Adelaide Stock, Fast Lead Times
Panels held locally in Adelaide. No waiting weeks for overseas shipments. SA-wide delivery, and Australia-wide freight available.
Trade & Builder Pricing
Volume discounts for contractors and builders. Direct supplier pricing — no unnecessary markup layers in the supply chain.
Tested in Australia's Climate
Designed to perform in SA's extreme summer heat. EPS doesn't absorb moisture and won't rot, warp, or corrode over time.
Real Technical Experience
We've installed hundreds of coolroom panel systems. We understand how panels go together — and can advise on your build project.
Dual-Purpose Panel Range
Whether you're building a coolroom or a cool room — we have the right panel and the right expertise to get you there.

Frequently Asked Questions
What is the difference between SIP panels and standard EPS insulation panels?
Structural Insulated Panels (SIPs) are specifically engineered to carry structural loads — typically with rigid facings bonded to an EPS or polyurethane core. Our EPS sandwich panels function as SIPs when used with appropriate structural facing and connection systems. They're used in both coolroom applications (non-structural insulation) and modular building projects (structural use with appropriate engineering sign-off).
Are your panels suitable for residential housing and modular construction?
Yes. Our EPS panels are used for container home conversions, backyard studios, granny flats, modular housing, and prefab construction. For full structural applications we recommend working with a building designer or structural engineer to confirm panel selection, connection details, and NCC compliance for your project.
What sizes do your SIP panels come in?
We stock standard lengths of 2.4m, 2.7m, and 3.0m across our 35mm, 50mm, and 75mm panel ranges. Roof panels are available in longer lengths up to 6.0m. Custom lengths can be quoted for volume orders. Contact us with your project dimensions and we'll recommend the right configuration.
Do you deliver SIP panels outside of Adelaide?
Yes, we deliver Australia-wide. For large panel orders, freight is arranged via pallet delivery to your site or depot. Contact us for a freight estimate to your location. We regularly supply customers in regional SA, interstate builders, and remote project sites.
How do the panels connect to each other?
Our panels feature a Z-lock and tongue-and-groove joining system that creates a tight, thermally efficient joint between panels. This eliminates cold bridging at panel joints — the same system used in commercial coolroom construction, proven over decades in demanding refrigeration environments.
Why does a coolroom panel supplier also offer panels for housing?
It's a question we get often, and it's a fair one. EPS insulated sandwich panels are fundamentally the same product whether used in a coolroom or a modular home — the difference is in the application and engineering context. As the Australian government invests in SIP-based and modular housing to address the housing shortage, we see a natural extension of what we already do. We build coolrooms. And cool rooms.
Can I get a quote for a complete SIP panel package?
Absolutely. Send us your floor plan, wall heights, and roof dimensions and we'll put together a full panel package quote. We can supply panels only, or discuss supply-and-install for coolroom projects in Adelaide and across SA.
