Bespoke SIP panel fabrication to project drawings and specification.
Precision beam saw cutting for clean, accurate edges.
Cross-cutting to cut panels to specific lengths.
Panels clearly labelled and packed for logical assembly.
SIP packs suitable for residential, commercial and multi-unit builds.
Our SIPs can be supplied and delivered for Nationwide delivery or collection from our facility.

Our SIP panel cutting service is powered by a Stori Mantel beam saw, engineered specifically for high-accuracy panel fabrication at scale.
This technology allows us to manufacture SIP panels with tight tolerances and consistent panel sizing. Clean, square edges for faster site assembly. The result is a fully prepared SIP panel kit, reducing on-site adjustments and helping your build progress faster and more efficiently.
Our SIP panel fabrication service is designed to support a wide range of construction professionals and projects, including:To complete your SIP build, we can also supply associated structural components, including:

Contact us to discuss your SIP cutting & fabrication project scope and requirements.
Send us your available plans, elevations and dimensions, together with the site location and intended build programme. We’ll review the information, discuss your requirements and confirm what else is needed to prepare a quotation and progress the fabrication design.
We convert your drawings into SIP fabrication data, including a detailed component schedule.
Our workshop cuts, routes and prepares each SIP panel using precision machinery.
Your SIP Panels are packed, labelled and delivered nationwide or made ready for collection.

As experts in SIP Panels we can also help with on-site SIP panel installation. Our team can advise on delivery, assembly sequencing, and — where available — provide installation support.
We have many great case studies where you can see all our SIP construction projects.
