Thermographic surveys show, using infrared cameras, where heat is being lost through a home through a colour chart. White is the hottest temperature and black is the coldest.
By measuring the temperature of external and internal walls and finding out where heat is being lost, Ploughcroft can offer advice for improvements concerning insulation in the roof or ceiling which will decrease the amount of heat escaping.
Below is an idea of the information a customer will receive in a thermographic survey from Ploughcroft:
The thermal image above reveals significant decreased temperatures extending across sections of the ceiling and at the all/ceiling junctions, seen in colder blue and purple colours. These decreased temperatures are suspect and indicate cold air ingress via regions of damaged/missing insulation and/or poor building detailing.
Thermal analysis of the above image reveals excessive decreased temperatures running along the wall/ceiling junctions, seen in colder blue and purple colours, indicating cold air ingress via damaged/missing insulation and/or poor building detailing. Circular shapes seen within the anomaly suggest that cold bridging of plaster dabs is contributing to the decreased temperatures.
Suspect decreased temperatures highlighted in the above thermal image, in colder purple and blue colours, indicate cold air ingress in this location; possibly due to poor detailing in the floor/wall junction.
The following thermal images reveal further example of suspect decreased temperatures, in colder blue and purple colours indicating cold air ingress ia poor detailing and or damaged/missing insulation; particularly at wall/ceiling junctions. Similar to some of the previous pages, circular cold spots indicate that cold bridging of plaster dabs is contributing to the decreased temperatures.
The corner of the wall in the above thermal image reveals higher than expected temperatures at the building junction indicating potential heat loss via damaged.missing insulation and/or poor building detailing at the junction.
In addition to this analysis, you will receive advice on what steps to take to improve the heat loss of your home or commercial building.
