Garden Rooms constructed with SIPs are ideal for all sorts of purposes.
Construction with SIP panels provides a super-insulated garden room that can be used all year round as a garden office, studio, extra workspace or summer house.
We offer SIPs extension kits with panels cut to customers’ dimensions in size and shape, meaning that construction is speedy and within the capabilities of competent amateur builders and professionals.
Extension Kitz can guide you through your SIP panels garden building project from the first drawings to the final construction.
SIP panels have a layered construction in which two structural facings of oriented strand board (OSB) are stuck together with a core of super-insulating foam.
SIPs are ideal for all types of garden buildings and ground-floor extensions. They are a popular building material in other parts of the world, including the USA and Scandinavia, and their benefits are becoming more and more popular in the UK.
The design of the SIP panels is an ideal building solution for buildings like garden studios or other garden rooms because:
The panels are light, strong, and easy to manoeuvre in tight spots.
SIPs can be cut to customer specifications in almost any shape and size, giving unrivalled design options.
The panels are the largest part of the structure and are manufactured in our factory, meaning considerably less mess on site.
The foam core of the panels provides a high degree of insulation, making SIPs construction eco-friendly.
SIPs construction is relatively simple compared to traditional construction methods, allowing for fast installation and making our extension kits suitable for competent home builders or professionals with a small team.
We are one of the UK’s leading suppliers of SIPs, manufacturing and cutting panels to customer specifications in our factory in North West England.
Our SIPs extension kits require a flat concrete foundation. It is possible to avoid laying a new foundation by reusing the base of previous structures like sheds or garages.
Maintenance and care of garden rooms constructed with SIPs
SIP panels are up to seven times stronger than timber and do not deteriorate with time or exposure to the elements.
The panels comply with all building regulations and have fire-resistance properties that exceed British Fire Safety regulations.
Our garden room kits all come with a ten-year guarantee.
How energy-efficient are SIPs garden rooms?
Very! The design of the structural insulated panels with their super-insulating foam core creates a high level of thermal efficiency. Garden rooms constructed with SIPs are at least 50% more insulated than timber frame buildings of the same size and require far less heating energy.
In addition, the assembly method of our extension kits means that the corners and sides of the panels are tightly pressed together, preventing leaks or draughts.
How long does it take to install a garden room with a SIPs extension kit?
Construction time with SIPs is much faster than with other methods. Every extension kit comes with numbered panels for ease of assembly and a competent team should be able to assemble the garden room in 2 – 3 days.
We can provide guidance if there are any problems or some customers choose to use our experienced construction team.
Most garden rooms come within permitted development rules, but a large building or a garden room that is in proximity to a boundary may require planning permission from your local authority.
If the garden room is to be used for business purposes, it may also need planning permission.
It is always best to be sure before you begin your project. In the worst-case scenario, you would be asked to remove a building erected without permission. We can offer advice about planning permission as we have had much experience in this area.
What is the cost of constructing a garden room with SIPs?
It is impossible to give a typical cost as every extension kit is bespoke with panels cut to the customer’s individual requirements.
