Overview
The 50mm EPS insulated sandwich panel (6m, roof) delivers maximum span coverage in a single panel — eliminating mid-roof joins on large cool rooms, warehouses and commercial modular structures. At R ~1.19 m²K/W with 0.45mm steel skins and a 1,000mm cover width, six panels cover a 6m-wide roof bay completely. The EPS sandwich construction means insulation is integral — no separate ceiling lining required in most applications.
Key Features
- 6m span — no mid-roof joins: maximum coverage per panel on large commercial roofs.
- Integral insulation: EPS core eliminates the need for separate ceiling insulation in most builds.
- 1,000mm cover width: 6 panels = 6m, 10 panels = 10m — scale up efficiently.
- Flat sandwich profile: clean roof surface, no corrugations, compatible with standard panel fixings.
- 0.45mm steel skins: durable both faces — weather-resistant exterior, cleanable interior.

Maximum Span, Minimum Joins
The 6m panel is the choice for large projects where minimising roof joins matters — fewer joints mean fewer potential leak points, fewer thermal bridges, and faster installation. It’s well-suited to the SIP-style builds we support for container homes and modular housing. Pair with our 75mm EPS wall panels for a complete insulated building envelope. For shorter roof spans, see our 4.8m and 3.6m options.
Installation Notes
- Panels lay perpendicular to purlins; fix through top skin into purlin with self-drilling screws.
- Apply butyl tape or foam sealant at all end laps and panel side joints before closing.
- Use ridge cap flashing at the apex and eave trim at the lower edge.
- Minimum roof pitch: typically 2° for flat EPS sandwich roofing panels.

FAQs
What is the maximum span for a 6m EPS roofing panel?
The 6m panel is the longest in our standard range, covering roof bays up to approximately 5.7m internal span with standard eave allowances. For spans beyond 6m, panels are typically lapped or supported by intermediate purlins.
Do I still need ceiling insulation with these panels?
In most applications, no. The EPS core provides the thermal separation between roof exterior and interior. For cool rooms and refrigerated spaces, the panel alone provides R ~1.19 — sufficient for cool room and light freezer applications. Consult your refrigeration engineer for specific requirements.
Are these suitable for a SIP-style modular home roof?
Yes — EPS sandwich panels are closely related to SIP construction and are used in modular and container home roofs. The 6m length is popular for larger floor plans where minimising roof panel joins is important.
What fixings are used for 6m roofing panels?
Standard sandwich panel roofing screws into purlin or structural top plate, with sealing tape at end laps and ridge cap at the apex. Contact us for a fixing specification sheet.
Can I order 6m panels in bulk for a large project?
Yes — we supply trade quantities and offer volume pricing for larger orders. Contact us with your panel count and project details for a quote.
