sustainable retrofit

We know the stats:
• the housing stock in the UK is amongst the oldest in Europe.
• approximately 3.5 million occupied homes were not suitable and did not meet the Decent Homes Standard in 2020, with 4% having serious damp issues.
• 32% of category 1 hazards are for excess cold.


EJOT’s growing range of innovative solutions for the installation of ETICS (External Thermal Insulation Composite Systems) – also known as EWI (External Wall Insulation) systems – is playing an increasingly important role in enabling quality and performance to be optimised in external envelope refurbishment and new build projects. Mark Newell, EJOT UK’s ETICS specialist explains why.

housing stock

The UK has some of the oldest housing in Europe, with approximately 20% of current dwellings built before 1919 – that equates to about 5.8 million homes in the UK that are over 100 years old. And, using data1 to 2017, 17% of the current housing stock has been built since 1990. That means that roughly 23.6 million homes across the country were built over 30 years ago.


Dan Court is a U-shaped seven storey building containing 138 one, two, and three-bedroom apartments in Wembley, London.

Following the ban on combustible materials in the external walls of relevant buildings over 18m1 in England which came into force in 2018, Catalyst Housing appointed Higgins Partnerships to undertake the reclad works and deliver a safe and compliant estate.


There is a real need to ensure we have a retrofit program that provides a sustainable solution for the existing UK building stock.

Buildings contribute 39% of global energy related carbon emissions, with the majority (28%) coming from operational emissions. This means that over a quarter of total carbon emissions are from the need to heat and power our homes.

The Problem
Armed with the latest U-value testing equipment, and excited by the improved thermal performance data shown by the next generation SprayCork material in the lab, Corksol set out to assess the product’s thermal insulation performance as a Thin Internal Wall Insulation in a real-life situation.

The background to the testing was the UK Government’s March 2021 report on Thin Internal Wall Insulation (TIWI), which highlighted the potentially very large nationwide benefits for both energy efficiency and fuel poverty from high performance TIWI systems. The chosen test property was an 1890’s solid walled Yorkshire stone detached cottage in Halifax.
