Competent market power for the window and door industry
There is a proverb that says: A chain is only as strong as its weakest link. This also applies to the fenestration industry. Doors and windows only perform as well as the seal.
BFK produce windows from VEKA PVC profiles and have specified Schlegel Q-Lon PU foam seals, QL 4465 and QL 9756 as sash and frame seals.
Pile fibres in brush pile seals move independently and are flexible, they seal perfectly against moving elements and also uneven surfaces.
