PUF Sandwich Panel — PUF Sheets Manufactured for Wall, Roof and Cold Rooms

PUF sheet, puff panel, insulated sheet — one product, many names

Buyers search for this panel under half a dozen names, and the mismatched vocabulary causes real confusion when comparing quotes. To be clear: a PUF sheet, a PUF panel sheet, a puff panel (a common spelling of PUF), a PUF insulated sheet and a PUF sandwich panel all describe the same three-layer product. There is no material difference between them — only the word the seller happens to use.

We use that name because it describes the build honestly: steel–foam–steel. But whether your drawing says “PUF sheet”, “insulated sheet” or “puff panel”, you are asking for the same panel, and we quote it the same way. Mapping these names in one place is deliberate — no ranking page states plainly that these are one product, and it is the single most common reason buyers mis-compare sellers.

Panel layers and facing options

The three layers are what make the panel work. The two outer facing sheets carry the finish and the structure; the PUF core in between carries the insulation.

The facing choice sets both the look and the environment fit: PPGI and PPGL for general wall and roof, stainless steel or aluminium for hygienic cold rooms and food spaces, craft paper where a lightweight backing is enough.

Thickness and size selection

These panels are made from 30 mm to 200 mm: 30 / 40 / 50 / 60 / 80 / 100 / 120 / 150 / 200 mm, with freezer-grade produced up to 150 mm. Covered width is 1000 mm (roof 1070 mm overall), and lengths run 2–15 m standard.

Thickness follows the job: thinner sheets for partitions and cabins, mid-range for sheds and better thermal control, and the thick end for cold rooms and freezers. Longer panels reduce joints but are transport- and site-dependent — a 15 m sheet needs road access and offloading space — so we confirm the workable length against your site. For the full thickness-and-size rate view, see PUF sheet price by thickness and size.

Wall, roof, cabin and cold-room uses

One panel, several jobs. As a wall, it is an insulated, finished partition or external wall in plain, baby-rib or micro-rib profile. As a roof, it is an insulated roof cover — for roof-specific span, slope and fixing depth, see our roofing page. As a cabin shell, it forms the walls and roof of porta cabins and site offices in one board. As a cold room, it is the thermal envelope, usually with a cam-lock joint so panels lock airtight.

Because it serves all of these, this build is the base product across our range — explore every PUF panel option we make to see how the wall, roof and cold-room versions differ.

How SAMAN manufactures and checks PUF sandwich panels

The sandwich is made by feeding two facing coils through the line, injecting polyurethane between them, and letting the foam expand and cure so it bonds to both sheets as one continuous board — not a slab glued in afterwards. That injected bond is what makes the three layers behave as a single panel.

On every batch we check facing gauge, panel thickness, foam rise and the tongue-and-groove profile so joints close cleanly and the panel sits flat. Panels are then edge-protected, stacked and bundled for dispatch from the nearer of our two factories.
