LOW-e

Absorbed energy causes heating, which leads to radiation. To save energy and improve thermal management, e.g. in buildings, the thermal emissivity is an important parameter. For absorber coatings and low-e coatings, the emissivity determines the effectiveness and economy of a coating. Low-e is the abbreviation for "Low emissivity", which means "low heat emission". The emissivity indicates how much radiation a body emits compared to the ideal radiator.

We carry out measurements for you regarding reflectance and emissivity at 82 °C / 180 °F in the range 3-30 µm of any coating as an integral value. Flat samples (any sample size, at least 5.5 x 5.5 cm) and also tubes can be measured. The method is non-destructive. By comparing different coatings, calculations regarding energy savings/gains can be made.

Fields of application:

• Reduction of heat input in summer through heat reflection outside
• Reduction of heat loss in winter through reflection to the inside
• Reduction of the perceived temperature due to low heat radiation
• Reduction of heat losses on solar coatings / absorber layers

Would you like to provide your facade with a Low-e coating? We can also help you with this.
