Why Line & Insulate a Garden Building?

If you are using your garden building as a workshop to be used all year round or installing a garden office it is a great idea to line and insulate it. 

Insulation to rear of the building
Lining of rear interior wall

This is most commonly done using the following options;


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.


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.

Usually the answer is no, as long as the conservatory does not cover more than half your garden area.

There are exceptions, such as installing conservatories on Listed Buildings or in conservation areas, so, if you’re unsure, it’s always best to check with your local authority.

Although planning permission is not usually required, your conservatory installation will need to comply with current Building Regulations.

Most of our garden buildings can be installed within a single day. Of course, timescales will depend on the size and complexity of the installation. A free survey will give you a general idea of what timescale to expect.


Yes. The vast majority of our garden buildings are with Regency being no exception. Our best advice is to visit our showcentre to see the buildings on display and let us provide you with a design based on your dimensions.

Yes. We recommend using floor bearers for the entire Woodlands range. This is because the floor joists are not pressure treated and are therefore not suitable to be placed directly on the ground. All of our floor bearers are pressure treated and will last a long time.

The best type of base would be one made from paving slabs or a solid concrete. We also recommend our “Cousins Easi-Base System” made from 50 x 75mm sawn pressure treated timber with 80mm screws for fixing.
