FAQs

The maximum span for the 97mm thickness panels is 3.66m. The maximum span for the 122mm thickness panels is 4.88m. The 610mm roof/floor panels can be joined end-on-end for spans over 2.44m and up to 4.88m.
The 2.44m x 1.22m SIPs weigh approx. 46kg & the 3.0m x 1.2m SIPs weigh approx. 70kg.
Please email us a delivery postcode, and we would be more than happy to confirm the cost of delivery.
For our on-site installation service, the number of days of construction would depend on the size of your SIPs studio, your location from us and what the access is like.
The panels are all rebated 50mm (apart from the roof/floor SIP panels, which are rebated 100mm). If you are cutting the panels on site to produce your studio, you will have to rebate them again. The panels can easily be rebated with a simple hand saw or a hot wire rebating tool.
We do not produce internal walls; it is more cost effective to fit simple stud walls, as they do not need to be insulated.
The approx. U values for the 97mm SIPs are 0.30 w/m²k and for 122mm SIPs are 0.22 w/m²k. If you plan to use your studio all year round, you will get better thermal value from the 122mm SIPs.
We do not advise having roof lights, as it can compromise the structural stability of the roof.
Unfortunately, our SIP panels have not been structurally tested; therefore, they do not meet building regulation requirements, as we do not have the relevant data to show. For this reason, we tend to stick with simple, stand-alone garden studios under permitted development.
Yes. Externally you will need to protect the wall with a breathable membrane and internally, you will require a vapour membrane.
You can create a small hole from outside to inside of the wall panel to run electric wires through. Where the wire is in contact with the insulation, you will need to cover it with a small plumber’s pipe. After the vapour membrane and battens have been fitted to the internal walls, you can run the wires along before applying the plasterboard.
No, we supply a sub-frame to sit on top of the flat head screws, and our SIPs floor then sits inside the frame.
No, we supply battens that are attached to the underside of the SIPs floor to raise the studio of the concrete slab foundation and allow for airflow.
They are shower resistant, however they will need to be covered over with a waterproof sheeting if not being used straight away.
Yes, as part of our installation service we will apply the breathable membrane and battens, if we are supplying them.
We recommend either a level concrete slab, screw piles/ground screws or swift plinths. For more information visit - Garden Room Foundations  
No, we do not fit the EPDM. You need to have your cladding fitted and the EPDM tucked over it for the finishing trims to be attached.
No, we do not supply doors, windows, cladding or any internal finishes.
The maximum footprint is 30m2, anything over that will require planning permission and structural calculations.
Garden buildings do not require planning permission as long as the building is 2.5m maximum and within 2 meters of the boundary, or 3m maximum if over 2 meters away from the boundary. We always recommend checking with your local council as some areas may have special rules.
