termPIR AL GK in staff rooms adjoining a cold warehouse

Mark the heated rooms and cooler spaces on the plan. Where the warehouse wall meets a suspended ceiling, inspect the partition above it. Insulation that stops at the visible ceiling line may leave a strip of masonry exposed.

Give each wall a reference. Add its length, height, reveal widths and door swing to the sketch. Marking the new wall face shows whether there will be room for the architrave and fittings beside the entrance.

Mark equipment fixing points before installing the panels. For a heavy cabinet, establish the load, masonry type and distance from the bracket to its structural support. The fixing design must account for the full lining depth and the routes of concealed services.

The manufacturer gives a reaction-to-fire class of B-s1,d0 for termPIR AL GK in a specified end-use application. Check that the planned installation falls within the classification. Where the design requires a fire resistance rating for the wall, obtain evidence for the complete partition.

The manufacturer’s conductivity value of 0.022 W/(m·K) applies to the PIR insulation. For a panel with a 60 mm core, use 0.060 m when calculating the resistance of the core alone. Account for the plasterboard as a separate layer.

In this example, 60 mm of PIR plus 12.5 mm of plasterboard gives a nominal 72.5 mm before allowing for the fixing layer. Check that distance at radiator positions. Setting out from the insulation thickness alone understates the depth needed for the bracket.

For a 2600 × 1200 mm panel, the turn beyond the doorway can determine whether the board will fit. Measure the clear opening, corridor width and space to rotate the panel. Plan delivery before the route is lined with finished surfaces.

Mark panel edges and service openings on the wall elevation. If a panel must be divided for access, allow for the extra joint at a suitable location. Check socket positions against measurements in the room before cutting.

Insulating from the warm room reduces heat flow into the existing masonry and changes its drying conditions. Record the condition of the wall before lining it, particularly at floor level, at the soffit and around past leaks.

Where there are signs of damp, identify the source and assess how the wall can dry after refurbishment. This assessment also needs the temperature and humidity on both sides. Record the findings against the room reference before handing it over to the finishers.

List panel area, joint length and perimeter junction length separately in the take-off. Include cuts and reveal finishing at each opening. This defines the same finished condition for each quotation.

State who will prepare the masonry, install the fixings and finish the joints. Specify the surface finish required for painting. Inspect a complete wall, including corners, sockets and the ceiling junction.
