Agenda: Introductions & History The Principles of Movable Walls for Flexible Space How Movable Walls Can Affect Space The Importance of Acoustics in Movable Walls Specification & Technical Where Movable Walls Create Flexible Space Case Studies Summary & Conclusion
The Principles Of Acoustic Movable Walls Is To Create Flexible Space People need flexible space to move, work, learn or play
The Principles Of Acoustic Movable Walls Is To Create Flexible Space The main purpose of using sliding folding partitions is to be able to use your floor space more effectively Using the same area to hold different size functions, the client can put less floor space to more use Hotels and Conference Centres can create extra revenue through booking several smaller functions as well as large ones More economical for heating & lighting Teachers can take larger classes if short staffed Offices can use one boardroom as three meeting rooms
The Principles Of Acoustic Movable Walls Is To Create Flexible Space A movable wall provides all the acoustic & aesthetic qualities of a fixed wall Fixed & locked in place by spring loaded seals Quick and Easy operation insures room layout changes in minutes An acoustic movable wall has no floor track so when stacked the room has no interruptions to the floor finish

Movable Walls Typical System: Welded tubular steel box section peripheral frame 16mm acoustically separated particle board substrate High performance acoustic in fills Should have a mechanism that will exert a high pressure whilst adjusting to the contours of the floor Should have a quality method of locking the rollers in place once installed to ensure the panels stay level after operation Aluminium or steel overhead track with integral ceiling trim angle Powder coated aluminium retractable seals Satin anodised aluminium interlocking exposed or concealed edge profiles
Acoustic in Movable Walls: Movable walls need good acoustical properties to keep out the noise from the spaces either side of the wall Movable walls can give an outstanding acoustic performance with reductions as high as 59dB - more than a plastered brick wall Moveable wall systems should be laboratory tested to ISO/EN 20 140-3 & EN 20 354

Acoustic in Movable Walls Building Regulations (BB93) Approved Document E Requirement E4 now covers schools for first time section 8 of Document E states that the normal way of satisfying Requirement E4 will be to comply with Section 1 of Building Bulletin 93 Building Control Inspectors to ensure compliance with Building Regulations Pre-completion testing notification of non-compliance
Acoustic in Movable Walls Building Regulations (BB93) Building Bulletin 93 Intention to provide good working environment for both teachers and students Optimise speech clarity and intelligibility by considering room volume, shape and properties of room surfaces Tables give different RT values for each type of room other tables give minimum ratings for airborne insulation between adjacent rooms

Acoustic in Movable Walls Building Regulations (BB93) Rw is the weighted laboratory test rating (ideal conditions) Dw is the weighted measurement required on site The deduction from Rw to Dw for flanking transmission loss is generally calculated between 3-8dB The deduction from a normal system to one which requires an inset passdoor is 4 db Most areas in schools require Dw45dB (Classrooms) which would mean specifying a movable wall at between Rw48 53dB Note : Weighted means rated using the reference curve from BS EN ISO 717 Part 1

Specification & Technical: Full Technical Specification: TECHNICAL SPECIFICATION (L20/545) PROJECT Characteristics: Purpose made individual modular panel system incorporating anodised interlocking edge profiles. Integral magnetic strips providing a tightening torque of 70N per metre. Each panel is fitted with positive automatic self locking height adjustment device to the rollers (locknuts not acceptable). Telescopic end closure panel with internal vertical expanding section, this has a travel of 100mm and is fitted with retractable top and bottom seals. Construction: 16mm high density particle board class E1, with acoustic free separation from welded tubular steel peripheral frame. Maintenance free spring loaded two piece aluminium retractable seals to give a seal pressure of 2000N (204kgs) per metre. Mechanically operated rapid action crank mechanism using scissor link to extend acoustically broken aluminium pressure beams (Turn-cam mechanisms not acceptable). Internal insulation is supplied to achieve specified sound reduction using layers of sound reducing material.
Specification & Technical: Full Technical Specification: Operation: Individually operated by a removable winding handle inserted into the edge profile of each panel (not face operated), the telescopic closure panel is activated by one single escutcheon to the face that extends the peripheral seals in one single operation.
