At a glance
Construct better quality buildings, and build them faster, using Hemsec SIPs. Central to the development of many Modern Methods of Construction (MMC).
- CE and BBA Certified product, extensively tested for Structural, Acoustic and Thermal properties, including Fire Resistance.
- Easily integrated with a wide range of construction materials as a load or non-load bearing structure.
- Combined structure and insulation reduces wall thicknesses, maximising internal build space without compromise.
Applications
You can use Hemsec SIPs for all internal and external walls and roofs in domestic, industrial and commercial construction. You can manufacture an entire building using SIPs for walls, floors and roofs.
Hemsec SIPs are the best solution for applications where you need thermal efficiency. Depending on how they are used, a building manufactured using SIPs can out-perform most Passive House measures for low-energy use.
Hemsec SIPs are ideal for the following applications:
- Housing
- Education
- Hotel and Leisure
- Retail
- Commercial and industrial
Technical
We aim to provide you with easy to follow and relevant technical information, suited to the vast majority of applications.
Whilst we are confident the below data will help you specify, design and build your project using our Hemsec SIPs, we always encourage further conversations around your project specific requirements. This can make the most of our panels capabilities, allowing us to tailor our technical details with a project specific guarantee. Its good to talk during the early stages of your project…

Insulation Core:
A rigid thermoset polyurethane insulation core by BASF, provides the following benefits:
- Closed cell.
- CFC & HCFC free.
- <5 value for global warming potential (GWP).
- Zero ozone depletion potential (ODP).
Finishes
OSB Panel Facings:
The SIPs panel comprises of BBA Approved 15mm Internal and 15mm External Oriented Strand Board (OSB) grade 3 facings. OSB/3 has a thermal conductivity value λ of 0.13 W/mK.
Manufactured to specification EN 13986 and EN 300:2006, OSB/3 comprises of strands of softwood bonded together using a formaldehyde free synthetic resin.
The OSB boards are responsibly sourced and comply to FSC and PEFC chain of custody requirements. Further information and Certification can be obtained on request.
Specifications
Air Leakage:
Panel joint air-tightness = 0.01 m3/m2/hr at 50 Pa when tested to EN 12114 in accordance with BS EN 14509: 2013.
Acoustics:
Please refer to Hemsec SIPs BBA certificate, Section 12 – Resistance to Airborne Sound.
Fire:
Panel Internal and External OSB and CPB facings have Class 3 surface spread of flame to BS476: Part 7: 1987.
When Hemsec SIPs are used as part of a through-wall build up they pass the requirements of BS476 Part 21 fire resistance of load bearing walls and have achieved up to 75 minutes fire rating. Non-Load bearing walls can achieve up to a 90 minute fire rating (BS476 Part 22:1987).
Structural:
Loading Capacity Walls:
Hemsec SIPs 125mm Wall panel. The permissible design load values for the effective span of the panels based on the results of tests undertaken and analysed in accordance with BS5268-2:2002.
Loading Capacity Roofs:
Hemsec SIPs 175mm Roof panel. The permissible design load values for the effective span of the panels based on the results of tests undertaken and analysed in accordance with BS5268-2:2002.
For further technical information please refer to our BBA certificate or contact Hemsec.
Quality & Durability:
Hemsec SIPs are manufactured from the highest quality materials, using state of the art production equipment to rigorous quality control standards, complying with ISO9001:2008 standard, ensuring long-term reliability and service life.
The panels will have comparable durability to that of OSB/3 to BS EN 300 : 2006, therefore, provided the installation remains weathertight and damp-proof; a life of at least 60 years may be expected.
The long life expectancy of our product will reduce energy consumption of a building over its’ lifespan.
Guarantees & Warranties:
Warranties for SIPs construction are available from companies that offer warranty schemes and the majority of lenders are able to offer mortgages on SIPs houses. Hemsec SIPs are BBA / NHBC approved and are eligible for Premier Guarantee.
Detailing
Rebates:
Optional 50mm rebates can be formed in our panels during manufacture, applied to all 4 edges.
Accreditation
Hemsec will always strive to push the limitations of our product range. We do this by testing them more thoroughly than even the most rigorous accreditation requires us to do so; underpinning our promise of quality.
