Built-up roof and wall systems

Built-up roof and wall systems: JI Shield or equivalent
A built-up system is a roof or wall assembled on site in layers: liner sheet, brackets, insulation, then the outer sheet. We supply Joris Ide's JI Shield build-ups, or an equivalent to the same U-value, with every part on one quote and one delivery.

A deeper bracket takes more insulation and gives a lower U-value.

What's in a built-up system
The liner sheet fixes to the purlins or rails and forms the inside face. Brackets and spacer bars sit on top and hold the outer sheet at the right height. Insulation fills the gap, and the outer sheet keeps the weather out. The deeper the bracket, the more insulation, and the lower the U-value.
We supply the full build-up: liner, brackets and bars, insulation, outer sheets, fillers, sealants, fixings and rooflights, plus the ridge, barge and corner flashings folded to match in-house.
JI Shield from Joris Ide
JI Shield is Joris Ide's range of tested built-up systems: three roof build-ups and eight wall build-ups, with the sheets laid vertically or horizontally. Joris Ide publishes the thermal, acoustic and fire figures for each one, so the spec is set out before anything is ordered.
Joris Ide's figures include airtightness down to 10 m³/h/m², and wall build-ups tested to 120 minutes' fire integrity and 15 minutes' insulation.
Or an equivalent
If the job is specified as JI Shield "or equivalent", send us the spec. We'll quote an equivalent build-up to the same U-value next to the JI Shield price, with the data sheets for each, so you can choose with both in front of you.

Questions we’re asked
Built-up system or insulated panels?
Insulated panels go on in one layer, so they're quicker to fit. A built-up system is assembled on site, which gives more choice of depth, acoustic performance and outer sheet. We supply both, so ask us which suits your building.
What U-value can a built-up roof reach?
JI Shield roof build-ups run from 0.48 W/m²K with a 100 mm bracket down to 0.14 W/m²K with a 320 mm bracket. Tell us the U-value your building needs and we'll quote the build-up that meets it.
Can you quote from an architect's spec?
Yes. Send the spec or the drawings through the trade quote form and we'll price the full build-up, including flashings and fixings.
