How to build a ceiling?

The selection of accessories for securing ceilings depends, among other things, on fire resistance requirements.
Room height is also important.

For taller rooms, we should use nonius hangers. This is particularly true of ceilings, which must comply with strict fire resistance requirements. When lowering the ceiling by more than 18 cm and with fire resistance requirements, nonius hanger with a rotary hanger with nonius are used. In rooms without fire requirements, suspension wire with rotary hanger are used for ceiling lowers.

Nonius hangers have a higher load-bearing capacity compared to rods, and will therefore prove suitable for the construction of heavy ceilings.

The decision on the type of hanger to be used is determined by the height by which we wish to lower the room and whether there are possible fire safety conditions for the room in question premises.

The suspension wires allow a greater reduction compared to ES hangers. Es hangers are available in lengths from 75 mm to 300 mm, while standard suspension wires lengths range from range from 125 mm to 1,500 mm with the possibility of extension with a double hanger.

Hanger with suspension wire, which lowers the ceiling, is not certified for fire resistance and can therefore be used in rooms without such requirements.

The decision whether to choose ES hanger or suspension wires is also determined by the weight of the ceiling. It happens that standard ceilings become overloaded with various installations and technical devices such as fans, air conditioners, heavy lighting. Then it is worth reaching for ES hangers, which have a larger carrying capacity. All technical data can be found in our declarations, available at website www.metpol.pl

The most commonly used type of ceiling structure, especially for large rooms, is the two-level cross ceiling. The installation of a ceiling with a two-level structure is less labour-intensive, as we have less trimming of the CD profiles. Ceiling with a two-level construction is characterised by high rigidity. It is recommended for rooms exceeding 4m in height. For rooms where there is not enough space to install a two-level cross ceiling, we use a single-level cross ceiling, which takes up less space and a shorter distance from the false ceiling to the ceiling can be achieved. For narrow rooms, a single-level cross ceiling or otherwise single-directional ceiling is used.

The profile spacing in a suspended ceiling mainly depends on the maximum allowable ceiling loads. The greater the weight, the smaller the profile spacing. With heavy ceilings, it is advisable to compact the profiles, as well as the hangers that fasten this ceiling to the soffit. Profile spacing depends on also on how the plasterboard is laid. Profile spacing is also influenced by the type of frame, as the profiles are positioned differently in single-level and cross-level frames.
