Stormdry Independent Test Reports

The benefits of Stormdry have been evaluated in an independent report from the environmental management consultancy, Giraffe Innovation. The findings verify the energy and carbon savings that can be achieved by treating walls with the breathable water-repellent masonry protection cream.

The evaluation includes a peer review of existing data and test reports, updated SAP CO² figures for a model house with solid brick walls, and a detailed carbon footprint analysis for Stormdry. This has used a full lifecycle approach (from cradle to grave) to analyse the total carbon use for the production and application of a Stormdry treatment.

An estimate is given of the energy and carbon savings that can be made from lowered space heating requirements following treatment of masonry walls with Stormdry. Key findings are:

• Treatment with Stormdry can produce energy savings and a carbon reduction of up to 27% (excluding additional benefits from reduced evaporated cooling)
• The carbon footprint of a Stormdry application is 0.73 kg CO²e/m² (i.e. driving a small car for 2.4 miles, or less than 1% of a UK person's average carbon footprint)
• The average "carbon payback" for a Stormdry treatment is one month; the monetary investment (including materials and labour) is recovered in 6 years
• Over Stormdry's lifetime of 20-30 years, it can potentially save between 24 and 37 tonnes CO²e in total
