Benefits of SIPs
Structural Insulated Panels (SIPs) are at the forefront of construction methods, and a key element to the future of the industry.
High Thermal Performance
SIP construction provides excellent insulation performance from a relatively slim wall build-up.
Fast Construction
Factory-manufactured panels allow the building shell to be assembled efficiently on site.
Strong & Rigid Construction
Bonded OSB3 facings and an insulation core create a strong, rigid panel construction.
Airtight Construction
Correctly installed SIP construction can help achieve excellent airtightness.
Precision Manufacturing
Panels are manufactured to the agreed dimensions required for the project.
Energy Efficient
High insulation performance can help reduce the energy required to heat the finished building.
Manufactured in Leicester
Our SIP panels and garden room kits are manufactured in-house at our Leicester facility. We use BBA-approved OSB3 in our panel production, with components prepared to the agreed project dimensions for consistent and efficient on-site assembly.
By manufacturing in-house, we can produce made-to-measure panels and kits to suit individual project requirements.
Ground Screw Foundation Option
Ground screws provide a fast and practical alternative to traditional concrete foundations for many garden room projects. They can be supplied as an optional extra with your IRSIP garden room kit.
- Minimal excavation
- Fast installation
- Suitable for many garden room projects
Ground screw supply and installation are available at additional cost.
