SIDERISE MI | Mullion and Transom Acoustic Inserts for Curtain Walling

Siderise MI Mullion Inserts comprise of a range of specialist acoustic insulation materials designed to reduce vertical and horizontal sound transmission in curtain wall buildings, improving the performance of hollow-framed façades and glazed areas.

Whilst the inserts may be employed for the purpose of improving the sound transmission characteristics of the building envelope, for example outside to inside performance, they are more commonly used to assist in reducing flanking transmission between adjacent internal areas. This includes ‘room to room’ and ‘floor to floor’ flanking sound transmission.

Specific optimal solutions have been developed for each of the common conditions encountered in curtain wall constructions. The design of the appropriate insert considers, not only the acoustic performance, but also ease and practicality of installation.

In house manufacturing techniques such as CNC/die cutting or routing enables an accurate tailored fit within the particular hollow frame element.

Features and benefits:
Up to 41dB Rw ‘through’ frame on a 50mm mullion
Ease of installation
Wide range of base materials
Custom dimensions and shapes
