What are SIP Buildings?

Structural Insulated Panels are manufactured off-site and delivered as an instant and build ready to construct onsite. 


SIP's offer the highest levels of Thermal Performance of any readily available, off-site manufactured building material. 

Our SIP buildings are bespoke and built to the clients specific measurements and requirements. 


What Are SIPs?

Structural Insulated Panels

2021 Building Standards Compliant


SIPs panels are most commonly produced in the following thicknesses: 100mm, 125mm, 150mm & 175mm.


They are also available 200mm, 225mm & 250mm thickness if required.


Depending upon the internal & external finish of your walls, different thicknesses of SIPs panels can be used to provide the most energy-efficient combination to suit your needs.


Let us show you how SuperSIPs structural insulated panels can be used with a variety of internal & external finishes, including render.

Our SIPs Panels come in the standard size of 1.220m wide panels and are available in various lengths: 2.440m, 2.700m & 3.000m. The SIPs panels can be cut to produce a panel size specific to your bespoke building plan.


We select and cut your panels to ensure the most efficient use of the SIPs Panels to avoid as much waste as possible and to keep it cost-effective for the customer. 


World Class Thermal Performance

The thermal efficiency of a SIPs building is maintained throughout the building's life as SIPS offer one of the highest levels of Thermal Performance of any readily available, off-site manufactured building material.

The closed-cell foam of a SIPs panel prevents moisture ingress to degrade the insulation performance, this can occur with mineral wools and blown cellulose fibre products.


A building with SIPs will give energy savings of 40%-60% compared to a timber-framed building of equal size and insulation U- value.



U-Value Definition is a measure of air-to-air heat transmission (loss or gain) due to thermal conductance and the difference in indoor and outdoor temperatures, in relation to an area of material, expressed as w/m2k (Watts per Square Metre Kelvin).


The lower the U-Value, the better the level of Insulation is.

As the U-Value decreases, so do the amount of heat transferred through the material.

Thickness: 100 U-Value: 0.27

Thickness: 125 U-Value: 0.21

Thickness: 150 U-Value: 0.17

Thickness: 175 U-Value: 0.14

Thickness: 200 U-Value: 0.12

Increasing thickness increases thermal performance however the improvement in U-Value begins to diminish.

By improving the building energy design you can take advantage of such things as thermal mass and solar gain. This can prevent increased cost and still achieve the desired level of thermal performance and energy efficiency.
