Ceiling void

Where partitions do not run through the ceiling void , care must be taken to ensure that a flanking path is not created for the transmission of sound between adjacent spaces or for the spread of fire. Acoustic insulation or fire separation can be provided in the ceiling void if necessary. Typical examples include, suspended ceiling or raised access floor voids at partition lines, and the cavity formed at floor slab abutments to curtain walls. Whether you are insulating an existing ceiling or soundproofing a new build use acoustic ceiling insulation slab between the joists to achieve the required levels of soundproofing. Do not use thermal insulation rolls for this as they are low in density which means they will not block and absorb the airborne sounds.

Does the suspended ceiling have any fire resistance and are there any other risks in the void ? Is the void over a room or a corridor and what are the total dimensions of the void ? Are any cavity barriers provided within the void ? Easily removed with the tile, Soundblockers allow access to the ceiling void. When replace a special edge detail re-makes the acoustic seal. Four types of Soundblocker are available to meet specific acoustic performance requirements. In this situation the ductwork penetrations are not considered to impair the fire resistance of the floor construction. A flexible composite quilt designed for free-hanging in ceiling voids that reduces sound transmission between rooms and is suitable for use in both new build and refurbishment projects.

There were three cases where compartmentation in roof voids was effective and prevented fire spread throughout the void. There were five cases where mineral wool in wire netting was used as a cavity barrier in a roof space but was shown to be inadequate mostly due to holes in the barriers. If you have limited space available in your ceiling void to mount a standard recessed downlight then check out our range of shallow downlights. XBC range of high efficiency heat recovery ventilation units designed for ceiling void applications (suitable for external use with weather roof). Designed to save energy, improve indoor air quality and provide the lowest noise breakout.

If a detector is concealed in a relatively inaccessible area such as a ceiling or floor void , it is normally a requirement to provide a remote indication of its operation. The fully concealed grid and ceiling lining can be used in conjunction with Gyproc plasterboards and Gyptone and Rigitone acoustic ceiling boards to create a seamless, monolithic appearance. The ceiling void is the space between the internal roof and the ceiling level. In some buildings the ceiling void is left uncovere whilst in others it is covered by a ceiling. Typically, the ceiling void is used as a storage space for hiding pipes and wires out of sight.

This is because often, if left uncovere these items can look messy as they often vary in colour, size and shape. The void above a suspended ceiling , which accommodates the tension wires or other means by which the grid is suspended from the building structure, is commonly used for the routing of wiring systems and non-electrical services, such as pipework and ductwork. A variety of Baffle ceiling designs are available - The openness of the ceiling depends on the choice of baffle size.

Different Baffle arrangements have a greater impact on the acoustics, an important consideration where sound reduction is a requirement. HORIZONTAL FIRE BARRIER CURTAIN Preventing smoke from migrating through stairwells, skylights and ceiling voids to additional floors and areas of a building can be. From your description, you have a ceiling , below which you will be installing a skimmed plasterboard ceiling. Find Great Daily Deals on Lighting Online. Free UK Delivery on Eligible Orders!

When people refer to a glass ceiling , they are talking about the attitudes and traditions in a society that prevent. This detail can be utilised when prevention of unauthorised access into the ceiling void is required or when, in sports facilities, impacts from balls could dislodge the tiles. In most situations the suspended plasterboard ceiling will have been an integral part of the assessed acoustic performance, any hatches within it will need to maintain satisfactory acoustic performance.

A denser fire rated hatch should provide better acoustic performance than a non-rated hatch. Therefore in most apartment block situations a rated hatch is either required or is beneficial. Should it not be possible to acoustically treat the void using a barrier, perhaps due to its large depth, because the ceiling void contains services, or because the void is being used for air movement, then we would recommend the use of our Soundblocker system.

A minimum ceiling void of 150mm is required when concealed sprinkler heads are installed. The above shows a sprinkler head fitted using pipe work to drop the head to the desired level. This is the most desired option and can be used to fit sprinklers in a ceiling void from 150mm and upwards.
