not all upvc profiles are the same,
veka makes the difference !
All uPVC profile systems windows and doors are not alike. Each system is differently equipped with properties and abilities to withstand the rigors to which they are subjected. All products when first fabricated perform adequately, but it is how they stand up to years of use that separates the good ones from the bad ones. VEKA profiles result from unique VEKA production processes and are better able to handle stress and weathering caused by temperature, moisture and UV variations. This results in longer lasting and better performing, window and door systems. All uPVC window & door systems conform to DIN 1055 part-4, DIN 18056 which stipulate that permissible bending deflection cannot exceed 8mm.
