Technical approval with ATG certification

Quality controlePrior to a system being put on the market it is subjected to significant investigations regarding acoustics, water and wind tightness, in order to obtain the necessary approvals by the appropriate authorities, such as the WTCB (BBRI = Belgian Building Research Institute), BCCA (Belgian Construction Certification Association) etc...

Each profile system is subjected to the most stringent standards and is regularly checked for the tensile and shear strength of the connection. We continuously endeavour to ensure that the permitted tolerances are not exceeded.
