Fully-insulated SIP Roof Panels open up the possibilities

Build faster with SIP panel roof construction and eliminate the need for trusses - for more usable living space.

SIP Roof Panels will be part of your Eco-Friendly Build.  It is a more innovative approach to roof construction, making the most of available space whilst providing a fully-insulated solution.

What are SIP roof panels?

With 60% less timber – and no need for trusses – our SIPs building panels are ideally suited to roofs, turning what would have been an ordinary attic space into extra rooms, storage space, or a vaulted ceiling.

SIP roof panels arrive pre-cut, with insulation already fitted, and span from wall to ridge beam (all supplied by us) – with no need for further support.  This opens up more possibilities, and ensures you can make the most of the available space.

The advantages of a SIPs panel roof construction

We’ve outlined some of the main benefits from using SIPs in your roof construction, below:

  • Eliminates the need for trusses, meaning more usable roof space
  • Airtight, with reduced cold bridging
  • An even spread of high-quality insulation - eliminating inconsistencies
  • Does not degrade or deteriorate over time
  • Up to 3x faster than traditional methods - install a standard roof in just 1 day
  • 90% less wastage on-site (as our panels are manufactured off-site)
  • Lightweight and easy to work with
  • Zero reliance on weather conditions - for minimal disruption to the critical path
  • Easy installation - with reduced drilling and crane use on-site
  • Huge savings on labour - with reduced number of trades and supervision on-site
  • Excellent insulation values for increased resale value
  • Naturally more eco-friendly than other build types to reduce carbon footprint

Fully-insulated SIP roofs for new builds

Although SIP roof panels are fully insulated, they’re also relatively lightweight and easy to work with.  Because the panels are a solid structure, your team can safely clad and work on the roofs externally.  A typical domestic SIP roof can be installed within one day.

The versatility of SIP roof panels means you can install them as part of a wider SIP construction (such as a SIP house build), or for any other type of building work.  They’re particularly good for city areas where access is restricted.

With the extra space, you can leave a large open ceiling space (for storage or ventilation), install partitions (something we can provide) to add extra rooms, or opt for a vaulted ceiling.

Our high-strength, high-performance SIP panels are:

  • Non-toxic
  • Low carbon footprint
  • Made with 100% recyclable EPS
  • Energy efficient
  • Fire rated
  • Breathable
  • Extremely strong
  • Mould resistant


Here's what some of our customers are saying:

"We were very pleased with the overall professionalism and efficiency provided by Sips Eco Panels. We submitted our plans, having been drawn up by our architect, and from then on all design alterations & building regulations were dealt with very efficiently by the Sips Eco Panels team."

Graham Preston, Berkshire

Replacing an existing roof with SIP roof panels

SIPs building panels are a convenient, lightweight form of construction suitable for replacing the roof on most existing buildings.  Removing the need for trusses quickly allows for much more space in an existing home or building.

This is a popular option for self-builders who are looking for more space in their homes, or for large commercial buildings that rely on large mechanical ventilation systems – such as hospitals, care homes and schools – and are looking to increase space in an affordable way.

The energy savings when installing a fully-insulated SIP roof are significant, helping to reduce your carbon footprint and save on costs.
