SIP Panels & Building Systems
All the products to deliver your SIPs project — whether it is a Garden room, Home extension, Garden annex, Holiday Lodge, Golf simulator or any other building. Trade pricing and bespoke dimensions available on request.
SIP buildings can be erected in days, not weeks. Pre-cut panels arrive on site ready to assemble.
Specialist in Industrial Pressed high-density PU foam. CNC-cut to exact tolerances every time.
Every panel is CNC-machined. Openings, joints, and profiles are cut to ±1mm precision.
Faster build times, less waste, lower labour costs. SIPs deliver real savings on the total project cost.
SIP PANELS
Our structural insulated panels are manufactured using high-performance engineered wood facings bonded to a rigid high-density polyurethane (PU) insulating core under controlled factory conditions. This composite construction creates a highly efficient structural element, combining load-bearing strength with excellent thermal performance. Each panel is precision CNC-machined to exact project specifications, allowing for bespoke openings, complex geometries, service penetrations, and custom profiles to be incorporated directly during manufacture, ensuring rapid installation and exceptional dimensional accuracy on site.
Available in six standard thicknesses from 72mm to 197mm, with two sheet sizes available on selected thicknesses. Trade pricing and bespoke dimensions available on request.
SIP JOINING SPLINES
Our engineered timber splines are precision-machined to create structural, airtight panel-to-panel connections. Designed to match our panel dimensions exactly, they ensure a consistent, reliable joint throughout your build.
SIP KITS
Our complete SIP kits take your project from design drawings to a fully fabricated, ready-to-erect building package. We convert your ideas into detailed fabrication drawings, then manufacture every panel, spline, and structural element to exact dimensions. Alternatively if you require raw panel to process yourself , then we can also assist.
The Ashfield SIP Kit is our flagship garden room package — but we manufacture bespoke kits for any project type, including extensions, annexes, holiday homes, and commercial buildings.
