Stormdry masonry protection cream from Safeguard Europe – the specialist in damp and waterproofing, and masonry repair solutions – has been granted ‘verified’ status by the Energy Saving Trust (EST) in respect of its contribution to improving the energy performance of buildings.
The Energy Saving Trust’s verification scheme provides independent evaluation of performance for energy-efficient products. After considering peer-reviewed scientific papers and the results of long-term testing, the EST awarded the recognition to Stormdry for its claims to enhance thermal performance of masonry walls.
For instance, according to tests conducted on solid wall constructions by the University of Portsmouth, Stormdry treatment of masonry can provide energy savings of up to 29%. It does this by providing a ‘high-level’ of water repellency, preventing rain penetration of brickwork and keeping walls dry. Bricks have twice the thermal resistance when dry than when wet, making them insulate more effectively.
The EST arrived at the following conclusions from its evidence review: dry masonry has a lower thermal transmittance than wet; Stormdry masonry protection cream reduces heat-loss through masonry while inhibiting the absorption of water into sandstone, concrete, mortar and bricks – and that, after application, it allows for wet bricks to dry out completely.
Crucial to the performance of Stormdry is the depth of penetration into masonry; and the concentration of active ingredients in the formula.
The cream is said to penetrate far more deeply than other water repellents – up to 12mm in fletton bricks – so that it can bridge cracks and better keep out moisture. With an active ingredient level of 40% – compared to concentrations as low as 2.5% for some competitors – Stormdry is reportedly not only far more effective at excluding moisture from masonry; but also has a significantly longer life expectancy of up to 25 years.
The proof of its longevity was said to be seen in accelerated ageing tests conducted as part of its certification by the British Board of Agrément (BBA). Other performance criteria considered by the BBA included: water repellency, condensation risk, freeze/thaw-resistance and UV-resistance. The BBA also reportedly found that Stormdry resists the uptake of water into masonry substrates, without increasing the risk of condensation, while resisting both the effects of both freeze/thaw cycling and UV light.
The product is said to be easily applied by either brush or roller and will cure colourlessly to match the original wall within 12 hours.
