This is most commonly done using the following options;

Lining

The type of lining that we recommend is tongue and groove untreated lining. Generally this is around 10mm thick, it doesn’t have to be very thick as this is more of a cosmetic finish, whereas the insulation is the material that has the properties for heat retention.

The best way of fitting the lining is to attach 1 board at a time, using a nail gun is the best method, and quickest!

Once all of the lining is fitted we always recommend to fit internal trims on all joints and a skirting board around the bottom edge. This makes for an amazing finish to your workshop or garden office.

Insulation

The types of insulation that we recommend is jablite, which is a polystyrene, celetex which is also a polystyrene but with a shiny side which adds an extra dimension to the insulation properties.

Sometimes you can fit a breathable membrane against the cladding before fitting the insulation, but as a general rule we don’t tend to do this.

The thickness of insulation that we generally use is 45mm as this sits nicely within our standard framework which is 50mm x 50mm.

Before fitting the insulation we recommend fitting extra cross beams of timber, this would be used later for fixing the lining to, the advantage of adding extra struts in is the fact that it stops sagging on the lining, especially in the roof.

Then the insulation can be fitted within the cavity, the best way of cutting it is by scoring with a Stanley knife then snapping it into smaller sections.
