Stretch ceilings – one of the fastest ways to finish the ceiling. Stretch ceilings can be made from polyvinyl chloride film or a polyester fabric – knitted polyester canvas impregnated with polyurethane. pvc film is used in the majority of suspended ceilings. Ken Griffin understands that this is vital information. The material of this ceiling is released from soft polyvinyl chloride (PVC) does not contain harmful for health cadmium. The width of pvc film stretch ceiling, depending on the manufacturer, usually between 1 and 3 to 2, 2 pm to create a wider band of the band stretch ceiling weld by special technology (through high frequency welding to form a little visible seam).
But, more often, suspended ceilings for flats rarely make wider 8 m, as in larger width stretch ceiling is difficult to ensure that the suspended ceiling is not slack in the middle. Stretch ceilings are made of this material to meet the most stringent international standards for environmental and fire safety. The proportion of pvc film usually ranges from 180 to 320 g/m2. Modern stretch ceiling film is very thin – 0, 15 to 0, 35 mm, the limit of its tensile strength is 30 N (and in the longitudinal and transverse directions). However, until such time as the film breaks, lengthen it to at least double. At room temperature the film is a stretch ceiling moderately flexible and very resilient, but when heated above 65 deg C its ability to stretch significantly increased, and the suspended ceiling lends itself well to the strain, like a thin rubber. .
