Introduction To SIPs

Structural Insulated Panels (SlPs) are made up of an energy-efficient rigid urethane insulation, enclosed in a high-density OSB sandwich.

The foam core provides super thermal insulation, while the exterior OSB skins account for the high tensile and compressive strength.

This superior thermal performance of our SIPS significantly reduces heating & cooling costs, limits air infiltration and creates a quiet draft-free interior.

SIPS has long proved popular with those self-builders who demand the best possible construction techniques for their new home. By offering a super insulated structure, with very low fuel bills, additional room space and a quick and predictable build programme, SIPS meets their exacting standards and is recognised by a range of industry bodies.

The building is based on the post beam structure and the panels are joined using either the post or a spline. The spline is a unique sealed jointing system that minimises the amount of air that can pass through the joints.

Today, many buildings are built with a traditional timber frame structure and this trend is growing as Building Regulations / Standards strive for better thermal performance and the construction industry increasingly moves towards the off-site construction of buildings.

Structural Insulated Panel (SIP) technology is the next generation of timber based construction methods.

Demand for off-site construction methods such as SIPs is growing rapidly. This is being driven by factors such as, the availability of on-site skills being at an all time low and the need for organisations such as local authorities and housing associations to innovate when seeking Egan compliance. Hence SIPS is playing a major role in meeting this demand.

Advantages In Using SIPS

  • Highly energy efficient.
  • More controllable indoor environment than traditional construction 
methods such as masonry due to the superior air-tightness of the 

  • Low site wastage as schemes are designed, cut and palletised in the 
factory meaning no excess building materials are delivered to site.
  • All the components for a Project e.g. panels and ancillaries, come factory meaning no excess building materials are delivered to site.
  • All the components for a Project e.g. panels and ancillaries, come from one source, therefore there are fewer deliveries compared to more traditional construction methods where components can often be sourced from and delivered by a number of different distributors or manufacturers. The overall result is less transport, which reduces the project’s impact on the environment. 

  • Incorporates a room in roof, so it is an excellent solution to gaining more room space.
  • Panelised system enables a fast track building process, which helps to reduce construction time considerably.
  • Follow on trades can start work sooner as the SIPS is wrapped with a non-tenting breather membrane which offers a weather-tight shell helping the contractor complete the project faster. 

  • For the contractor and developer, faster completion of projects can result in earlier cash recovery, improved cashflow and can increase capacity through the ability to achieve more project completions in a year. 

  • Much easier to predict project completion times as the System is relatively simple to erect and requires no wet trades or brick layers. 

  • As a result of reduced time on-site, and as only trained and approved RKS staff will erect the SIPS, the likelihood of accidents on-site are reduced. 

  • Defects are vastly reduced due to the factory controlled manufacture, precise engineering and design of the system.
