Efficient SIP Panels for Construction
Bespoke SIP Garden Rooms – Energy-Efficient, Durable & Stylish
SIP (Structural Insulated Panel) garden rooms are a highly sought-after solution for homeowners looking to create a functional, stylish, and energy-efficient space in their garden. Built using advanced SIP panels, which feature insulating foam encased between two OSB (Oriented Strand Board) layers, these garden rooms offer superior thermal insulation, exceptional durability, and faster construction times—at a lower cost.
Why Choose SIP Panels for Your Garden Room?
✔
Outstanding Energy Efficiency – Keeps temperatures stable year-round, reducing energy bills
✔
Rapid Construction – Prefabricated panels allow for quick assembly, often completed in weeks
✔
Superior Strength & Durability – High structural integrity, resistant to harsh weather and seismic activity
✔
Cost-Effective Long-Term Solution – Higher initial investment but significant savings on energy costs
SIP Panels vs. Timber Frame – Which is Right for You?
- SIP Panels: Offer superior insulation (higher R-value), faster construction, and greater durability
- Timber Frames: Allow more design flexibility, ideal for unique shapes and curved walls

Our SIP Panel Projects
High-Quality SIP Panel Buildings
SIP panels are quicker to build . Every customer is unique. That’s why we customise every one of our plans to fit your needs exactly. Whether it’s a small garden room or a big grannyannexe , we’ll sit down with you, listen to your requests and prepare a customised plan. SBS Structural Insulated Panels provide superior thermal performance, which will last the life span of the building. This is due to the solid core of polyurethane (PUR) insulation throughout the structure which ensures that the building is heated evenly, remains free from cold spots and will benefit from reduced heating costs.
Cost-Effective and Sustainable Solutions
What are SIP panels? SIP panels are wooden panels with a foam core. SIP actually stands for Structural Insulated Panels which means that these panel are warmer than any brick wall. SIP panels are also stronger, more durable and cheaper than any other wall or panel. These panels can last around 60 years! Structural Insulated Panels (SIP) are
entirely recyclable and consist of two parallel faces of Orientated Strand Board (OSB) sandwiching a rigid core
of expanded polystyrene. The result is a strong composite offering a high axial load capacity, with excellent insulation
properties. Cold bridging is minimised with the boards being interlocked and thus reducing the air or heat loss
between them therefore providing an friendly structure that cuts energy bills and greatly reduces green house emissions (Co2.) In all, up to 35% fewer raw materials are used in SIP buildings.

SIP PANELS
Enhance the sustainability of your insulated garden buildings with premium SIP panels. These panels are designed to fortify your garden space's thermal envelope, ensuring optimal energy conservation. By significantly diminishing the heat exchange, your space remains temperate – cool during the sweltering summer months and cozily warm throughout the chilly winters. This thermal proficiency not only slashes your heating and cooling expenses but also reduces the ecological footprint of your contemporary garden rooms.
Our cutting-edge SIP panels are meticulously crafted in a controlled factory setting, which leads to a leaner consumption of materials and, consequently, a more cost-efficient solution for you. The precision in engineering translates to elegantly accurate structures, bestowing your bespoke garden rooms with superior finishes that are as aesthetically pleasing as they are functional.
