Profiled Cladding - Wall & Roof
This frequently employed method of construction for creating full or partial building envelopes, gives rise to a number of acoustic issues. Common examples include:
• Difficulties in achieving the required sound transmission loss performance due to the low weight characteristics of this type of construction.
• Noise generation arising from rain impact.
• Combined sound absorption requirements - where perforated liner trays or decks are employed that incorporate sound absorbent materials to the rear or within the hollow profiles.
• Internal ‘room to room' transmission problems arising from sound paths through voids within the envelope construction or from inadequate sealing at the line of abutment with internal walls (commonly due to the poor performance of the profiled trough closure detail).
We are able to provide a wide range of materials providing solutions to these problems. These include:
• High density boards and limp membranes for inclusion in ‘built-up' constructions.
• Thermal insulation layers providing enhanced acoustic performance.
• Faced absorbent linings and trapezoidal infills for use behind perforated trays or decks.
• Resilient thermal break strips for improvement in mechanical isolation of the outer sheets.
• Accurately shaped closure blocks and strips for filling profiled troughs.
Due to the wide variation in possible requirements, we recommend that the specific condition is discussed with our technical department.
