Energyflo Insulation Technologies has completed a cutting-edge carbon reduction retrofit project for Willmott Dixon and South Cambridgeshire Council.

The Edinburgh-based company’s Dynamic Insulation product has been retrofitted to homes in Longstanton, Cambridgeshire as part of the Rampton Drift project, and the monitoring phase of development is now underway.

The project aims to identify the costs, effects and benefits of a range of low-carbon, sustainable technologies by refurbishing existing homes on the estate.

Energyflo’s patented Dynamic Insulation product enables builders and designers to meet today’s ever-increasing demands for energy-efficiency and carbon reduction.

The technology easily integrates the insulation and ventilation system to capture the heat energy escaping through the building fabric and pre-warm incoming air. By recycling this heat energy the energy efficiency of a property can be improved by 25 per cent when compared to traditional insulation products.

The homes, which were built in the 1950s and 70s, have been upgraded with Dynamic Insulation and it is hoped that the development will become a model for the construction industry as the Green Deal comes into force next year.


The Green Deal supports the implementation of energy efficiency measures to households and businesses to reduce energy usage and save fuel costs.

Alan Cochrane, Principal Consultant (Energy Services) for Willmott Dixon, main contractor for the Rampton Drift project, said: "Dynamic Insulation was selected because it is one simple solution that easily integrates the insulation and ventilation system to improve energy efficiency and indoor air quality."

Leading the design consultation was PRP Architects, which specified Energyflo’s Dynamic Insulation to be retrofitted to the properties’ external walls. Nuaire was appointed to provide the ventilation solution to meet the carbon reduction objectives of the project.

Andrew Peacock, technical director from Energyflo, said: "One of the key aspects of our unique technology is that we can deliver the solid wall U-values in hard to treat buildings well beyond any other external wall insulation from a thinner and less intrusive build footprint.

"We are delighted that our market-leading Dynamic Insulation product has been selected to be retrofitted in the homes at Rampton Drift. As around half of homes in Great Britain do not have sufficient insulation and around 50 per cent more energy is used to heat and power homes than is used to power UK industry, this project has the potential to be an important template for the industry. It is also an opportunity to learn about the positive impact which insulation can have on homeowner’s bills."

Archie Ferguson, chair of Construction Scotland, said: "Carbon reduction targets present an important challenge to the construction industry. The need to demonstrate compliance with these targets has never been greater."

Construction Scotland is tasked with providing leadership and directing the Scottish Construction sector and will engage with Scottish Government Ministers, key stakeholder groups and the wider industry to fulfil this role.

Archie added: "This is an excellent example of a Scottish company delivering an innovative solution to help construction companies across the UK to meet these targets and enable homeowners to reduce their energy costs.

"It is of increasing importance for construction companies to collaborate and share ideas so that we may identify even more forward-thinking ideas which can benefit the industry."
