Your Structural Insulated Panels (SIPs) Specialists

We specialise in delivering high-quality Structural Insulated Panels (SIPs) using the renowned Kingspan TEK® Building System, offering a complete service for your structural building envelope. From bespoke self-build homes to large commercial projects, our off-site manufactured panels create energy-efficient, sustainable, and cost-effective building envelopes, engineered to the highest standards and built to last.

What are Structural Insulated Panels (SIPs)?

Structural Insulated Panels (SIPs) are a high-performance building system that uses Modern Methods of Construction (MMC). Each panel consists of a rigid insulation core securely bonded between two layers of engineered Oriented Strand Board (OSB). Together, they form a strong, lightweight, and highly thermally efficient solution, ideal for constructing walls, roofs, floors, and internal partitions.
Unlike traditional brick and block or timber frame builds, SIPs create a monolithic, airtight shell that delivers outstanding strength, minimal thermal bridging, and exceptional energy performance.

The Kingspan TEK® System

We are an approved delivery partner of Kingspan TEK®, one of the most trusted names in structural panel technology.

The Kingspan TEK® Building System is:

BBA Certified for 60 years, the maximum lifespan recognised for any UK construction method.
Accepted by warranty providers, including NHBC, LABC, Zurich and more.
Recognised by lenders and insurers, giving peace of mind that your investment is protected.

The TEK Building System comprises 142 mm or 172 mm thick Structural Insulated Panels (SIPs) with a high-performance fibre-free rigid urethane insulation core, sandwiched between two layers of Oriented Strand Board type 3 (OSB/3). It is used to construct walls and roofs, and intermediate floors using I-beams or open web joists.

Why Choose SIPs for Your Build?

Building with SIPs offers several unique advantages over conventional construction:

Faster Build Times. A typical four-bedroom home can be made weather-tight in as little as two weeks, keeping projects on schedule and reducing on-site disruption.
Exceptional Energy Efficiency. With very low U-values, continuous insulation, and airtightness, SIPs can cut heating bills by up to 50%, creating homes that are warmer in winter, cooler in summer, and cheaper to run.
Design Flexibility. SIPs allow vaulted ceilings, open-plan layouts, and striking architectural features without the limitations of bulky roof trusses.
Superior Strength. Proven to be stronger than traditional timber frame and even brick-and-block construction, SIPs withstand extreme weather conditions and deliver long-term structural integrity.
Sustainable Solution. Manufactured off-site with minimal waste, PEFC-certified timber, and precision CNC cutting, SIPs offer a greener way to build, supporting Net Zero ambitions.
