As part of The Times COP26 coverage our tenements pilot with the Construction Scotland Innovation Centre was highlighted as a way of insulating historic heritage buildings. Some tenement buildings are over 150 years old and as 36% of Scotland’s housing is flats, it presents a unique problem for the Scottish Government to reach NetZero targets

The trouble with Scotland’s tenements and how to lower emissions

In the article, Gabriella Bennett of The Times highlights several options for how tenement building could reduce their emissions and cites the insulation pilot for tenements. Using our eps bonded bead insulation superbead, we designed a way of insulating the tenement properties as they have no cavities. The install was carried out by Everwarm after being trained by us on how the system works.

“One possible solution is expanded polystyrene beads, which when bonded with adhesives provide a high resistance against heat loss in lofts and suitable walls. In a year-long pilot in 2019 the product was installed at ten tenement flats across Scotland to gauge its effectiveness. Residents saved an average of £136 a year in energy bills and reduced CO2 emissions by 750kg a year.”


As a business, we are dedicated to finding insulation solutions for our built environment with the aim of reducing damage to our natural environment. The tenements pilot was designed as a specific solution to this Scottish problem. Below are some of the key findings from the pilot.

• SAP rating improved between 5-8 points

• 3,450kWh/yr average energy reduction

• 750 kgCO2/yr in emissions curbed

• £136/yr saved on natural gas energy bill

• If applied to all walls in some analysed dwellings, £800/year could be saved.

• Showed that due to its less invasive installation method, many pre-1919 builds could be effectively retrofitted in this way.
