Energy certification, allows the consumer to provide information on the energy performance of materials, which includes reducing costs with energy use.
Efficient windows have characteristics that contribute to increase the thermal and acoustic insulation of homes or trades.
Double glasses and insulating profiles.
Inefficient windows can favor condensation in glass and profiles, visible situation when significant temperature differences occur between the interior and the outside.
When, in winter, we put our hands on the glass or the frame and feel they are excessively cold.
Sealing problems at the junction of windows with walls. Gables on the windows elements.
Air passage uncontrolledly can indicate poor performance.
Efficient windows are windows that, due to their characteristics, contribute to increase the thermal and acoustic insulation of buildings.
SEEP - Energy Product Labeling System is a voluntary marking or labeling system that allows consumers to compare the energy performance of products by their classification.
An energy labeling system for windows is now available in Portugal.
It easily allows you to identify the main thermal characteristics of the window.
Each window has a label with the color scale and the other of registration.
