Home > Companies > Siderise Group > SIDERISE Window Reveal Liner (formerly Lamaphon WRX)

A decorative and robust reveal liner for use in secondary glazing. They provide a practical means of improving the sound insulation performance of secondary glazed windows. Their application to the reveals substantially reduces the reverberant sound field in the void formed between the primary and secondary glazing.

SIDERISE window reveal liners comprise an absorptive core of dense rock fibre insulation held within a covering of perforated sheet metal, which is formed around the sides and top of the core. The dense rock fibre core is of a special construction to provide improved impact resistance. As standard, the core is faced on both surfaces with a non-woven glass fabric to provide anti-dusting characteristics whilst remaining acoustically transparent. The perforated metal covering is finished by either polyester powder coating or anodizing for aluminium versions as required.
