JANS toitures
A well-built house is above all a perfectly insulated house. A badly-built roof leads to unnecessary energy consumption. Waterproofing and insulation problems that are accentuated by climate changes (rain, wind, snow, frost), have long-term negative effects on the home and general wellbeing. A roof must therefore be in perfect condition to ensure optimum protection throughout the entire year.More about JANS toitures
