The range here offers much improved acoustic performance over standard brush type seals which are not designed to provide for decent sound insulation. In our experience most soundproofing issues or noise leakage problems are down to either a lack of acoustic doors seals or badly fitted / damaged door seals which have gone unnoticed. Also it is common to find acoustic door seals fitted to the head and jamb but the threshold, which presents the largest gap often has no acoustic seal fitted at all.
We have surface mounted acoustic door seals, rebated acoustic door seals and adhesive acoustic seals. The majority are also fire rated with silicone inserts.
