Self Insulated Panel buildings

What is a Self Insulated Panel building?

Discover the pinnacle of eco-efficient construction with our Self Insulated Panel buildings, boasting cutting-edge Structural Insulated Panels (SIPs) technology. Meticulously crafted to redefine modern building standards, these SIPs are a testament to engineering excellence, providing unparalleled thermal insulation with their high R-value Polyurethane foam core. Embrace a sustainable future and slash your energy bills by up to 50%, thanks to this energy-efficient marvel that outperforms traditional timber framing.

Our SIPs not only champion thermal efficiency but also herald an era of eco-conscious construction. By pre-optimising and cutting panels, we minimize on-site waste, reflecting our commitment to environmental stewardship. The lightweight nature of these structural insulated panels UK-wide streamlines installation, expediting build times and significantly reducing labour costs – a testament to SIPs' cost-effectiveness.

Versatility is at the heart of our SIP offerings. Available in a spectrum of thicknesses – from a sleek 72mm to a robust 197mm – and customisable to any design intricacy, our panels are ideal for garden rooms to ambitious architectural projects. Whether you're crafting a cosy cottage or an avant-garde space, the adaptability of SIPs ensures your vision comes to life without compromise.

In the quest for sustainability, strength and serenity unite in our Self Insulated Panel Buildings. Expect superior energy efficiency, robustness, and tranquil interiors due to the impressive airtightness that curtails drafts, noise penetration, and energy wastage. This translates into lower CO2 emissions and tangible savings.

Our insulated roofing panels offer an oasis of comfort year-round. During the UK's warm summers and frosty winters, they maintain an optimal indoor climate without the need for additional insulation.

All of our kits are made from Structural Insulated Panels (SIPs) which we manufacture by injecting highly insulated Polyurethane between two sheets of structural OSB3. The panels form the floor, walls and roof creating an incredibly rigid, highly insulated passive standard structure. The panels are fabricated into components that act like giant Lego blocks allowing you to assemble the core structure quickly and efficiently. Choose from our huge range of stock buildings or our bespoke building service. We also offer a panel only service.
