Composition

Trimform insulated panels consist of a core of polyisocyanurate (PIR) insulation sandwiched between a heavily profiled external weather sheet and an internal shallow profiled liner. The PIR insulation bonds to the steel sheets during the manufacturing process, together the insulation and steel form strong, rigid panels with good thermal performance.

Trimform roof and wall panels are manufactured in a process certified to ISO 9001:2008.

Trimform roof and wall panels have been tested by the Loss Prevention Certification Board and comply with the requirements of LPS 1181:2005. Part 1 Issue 1.1: Series of Fire Growth Tests for LPCB Approval and Listing of Construction Product Systems – Part 1: “Requirements and Tests for Built-Up Cladding and Sandwich Panel Systems for Use as the External Envelope of Buildings.”

Thermal

The PIR insulation within Trimform insulated panels has a low thermal conductivity that gives the panels their good thermal performance. The large panel dimensions and the edge lap seals give Trimform insulated panel systems good resistance to air leakage.

Trimform insulated panels consist of two coated steel profile bonded to a core of PIR insulation; they may be used to form roofs, down to a 4º pitch, and walls. The system includes a comprehensive range of guttering, flashings, sealants and rooflights.

The Trimform system offers rapid coverage and swift completion of a weatherproof building envelope to give a high performance building.

Performance

Structure

Trimform insulated panels are designed to be supported by and fixed to steel or timber purlins. Steelwork for insulated panels should be within the tolerances given in BS EN 1090-2:2008 +A1:2011: fixing planes on adjacent purlins should be less than L/600 apart (where L is the purlin spacing).

All Trimform insulated panels are suitable for spanning purlins at 1.8m centres. Consult our Technical Department for guidance on using the panels on purlins at centres greater than 1.8m.

Trimform insulated panels should be isolated from preservative treated timber purlins by PVC barrier tape applied to the bearing face of the purlins.

Whilst panels may be fixed through valleys or crowns, Trimform recommend valley fixing: accurate fixing is easier to achieve, loads on the fixings are smaller, the fixings are less likely to distort the weather sheet, and better compression of the sealant is achieved at end laps.

Fixings should be stainless steel or carbon-steel self drilling screws with a high thread to restrain the weather face of the panel and should have press-on or integral caps to match the finish of the panel. To prevent water penetration each fixing should have a 19mm diameter EPDM washer.



Butted single span purlin system

The system is required for buildings of a single span length and is efficient for short spans or light loadings. Butted purlins are also useful for frames which have large clear spans and where large frame deflections may be harmful to continuous purlin systems. Butted purlins can be used over supports or within the depth of the supporting section. Maximum span is 11.4m.

Butted purlin system

This system is useful for single-span conditions, either over-supports or flush with supports. The system is also economical for small bays or light loadings, where sleeves are not necessary.

Single/double span lengths

This system may be used with restraining or non-restraining cladding, and may also be used to support tiled roof systems. The system may require to be used in conjunction with sag-systems. Consideration should be given to handling and erection sequence when utilising the double-span section.
