Toptherm Energyseal by Tarmac is a nano technology that once applied to masonry prevents moisture penetrating into your bricks and mortar. It is breathable allowing any existing moisture within your brickwork to escape when drying out. Toptherm Energyseal is professionally applied by one of our qualified technicians. It penetrates deep into the masonry up to 10mm, drying completely clear in a matter of hours; brick colour remains unchanged. Once dry any water will bead off immediately. Toptherm Energyseal is guaranteed by Tarmac to last for 20 years.
Toptherm Energyseal will stop your brickwork taking in new moisture. This will result in your brickwork drying out over time and becoming more thermally efficient, reducing heat loss.
As well as increased heat retention in your home any existing internal damp areas caused by external seepage should gradually disappear. Any previous exterior mould, moss or damp patches should not return. Once Toptherm Energyseal has completely dried you can then safely hose off any future contamination from the exterior of your property.
Moisture present in your masonry walls will accelerate heat loss by conducting the heat from inside your home to outside. By removing the moisture you may reduce heat loss by up to 23%*.
Toptherm Energyseal is suitable for solid brick wall properties. Application is a quick process and once dry waterproofs your property, reducing heat loss without affecting the appearance of your home. In addition we will also clean the exterior of your home as part of the preparation.
In the report “Research Into The Thermal Performance Of Traditional Brick Walls 2013” by Saki Rhee-Duverne and Paul Baker for English Heritage the wet thermal conductivity values obtained indicated a clear relationship between moisture content and poor thermal insulation, with wet values being 1 .5 to 3 times higher. However, the wet thermal conductivity values obtained in the tests would apply where water can travel through the wall as a liquid; for example, where there has been prolonged ingress from wind-driven rain, faulty rainwater goods or drains. This highlights the importance of maintaining a building in a good state of repair. Problems could be exacerbated if incoming water is prevented from evaporating by an impermeable surface such as impermeable wall insulation.
