voestalpine Metsec offer a number of alternative ceiling systems. From MF ceilings allowing the clean lines offered by plasterboard ceilings to Spring tee systems for metal pan ceiling tiles.

MF System

The Suspended MF System ceilings are ideal for commercial and domestic applications, where services are to be accommodated and when upgrading and protecting existing structures. Ceiling height may be varied to accommodate services or ducting, etc. providing a high performance ceiling with sound insulation and fire protection.

They are compatible with the partitioning system and suitable for direct decoration or textured finish. Always suspend heavy loads, air ducting, lighting units, etc. directly from structural soffit to avoid loading of the suspension framing and always alienate connecting clips on primary channels.

Features and Benefits

• Easy to cut to length using tin strips
• Mineral wool can be incorporated for thermal or acoustic insulation
• Creates a seamless surface suitable to receive most decorative finishes
• Fits easily together
• Suitable for fixing all types of plasterboard
• Creates void above the ceiling for services
• Improved acoustic performances can be achieved by using Acoustic Hangers

Ceiling Lining System

Often used in commercial and domestic situations and suited to both new-build and refurbishment projects, the Ceiling Lining System is suitable for most internal applications.

It can be used under timber or concrete flooring with any proprietary Gypsum plasterboard and cavities can contain an insulation material.

Features and Benefits

• Easy to cut to length using tin snips
• Mineral wool can be incorporated for thermal or acoustic insulation
• Creates a seamless surface suitable to receive most decorative finishes
• Fits easily together
• Suitable for fixing all types of plasterboard
• Creates void above the ceiling for services
• Ideal to level poor concrete and wooden floors
• 20mm minimum drop

Spring Tee System

The Spring Tee System is designed for use with metal pan clip-in tiles manufactured by SAS International and Armstrong. Pull-out tests are conducted during the manufacturing process as part of the quality procedure to ensure correct fitting of tiles. The white perimeter channel is coated to code RAL 9010.

Features and Benefits

• The system is totally downward demountable
• Spring Tee available in lengths up to 6.0 metres
• Quick and easy to install
• Accessories available
• Formed from pre-galvanised mild steel

Resilient Bar Under Timber

The sound insulation performance of some ceiling systems is dependent upon the attachment of a Resilient Bar to the underside of the joists and perimeter noggins on all four sides of a room. The Resilient Bar is fixed at right angles to the joists at 450mm maximum centres for single or double applications. When 2400mm board is being used the Resilient Bar will need to reduce to 400mm centres.

Bars are jointed by overlapping directly over joists with a minimum overlap of 200mm. Plasterboards are fixed with long edges at right angles to Resilient Bars at 230mm centres using Drywall self-tapping screws which should penetrate the Resilient Bar by a minimum of 10mm.

The Resilient Bar is designed to offer improved acoustic insulation when constructing a conventional ceiling under timber joists. Mineral wool insulation can be included in the floor cavity to improve acoustic performance. To ensure maximum sound insulation performance, screws fixing the plasterboard must not be in contact with the joists. When installing a dual layer of boards, all joints in the second layer must be staggered in relation to those of the first layer.

Fire Barrier Angle & Flat Strip

The Fire Barrier System is designed to restrict the passage of flames and smoke between suspended ceilings, floors or roofs. The fire barrier angle and flat strip system uses fire barrier quilt stitched with wire and faced on one side with 25mm galvanised wire mesh.

Fire tests have been carried out at Warrington Fire Research Centre using Lancaster Fireshield and at the Building Research Establishment using Rockwool Fire Barrier.
