Flexible PVC used in Swingflex and Strip Doors offers good Sound Reduction Characteristics because of its special composition.
With the onslaught of COVID-10, DMF suggest these type of PVC products can be installed to assist in prevention of passing on the virus, by creation of the PVC shield. DMF have supplied many of these single panel PVC shields over the last few months, for the purpose of isolation of workers. The shields create an enclosed working space, allowing employees to work in close proximity, but also with improved protection. See this link for more new by CLICKING HERE.
Medium Sound Transmission Characteristics Rm > 35dB (at as low as 5mm thickness).
- Other properties are:
Glass like transparency;
- Very good mechanical characteristics (see Specification sheets above);
- High flexibility;
- Smooth surface (excellent for hygiene/clean room areas and wet areas);
- High resistance to weathering and to chemicals (see Chemical Resistance table above);
These characteristics permit use in fields that are in part not accessible to products made of other materials. The sound transmission level attainable under conditions of use is subject to, on the one hand, the type of building, for example, room size, noise absorption rate in the room, and frequency range, and on the other hand, the method by which the PVC door material has been fitted.
In doing this, the best way of working with the material is to let it hang freely and, if possible, not stretch it too tight.
Every noise reduction measure is only as good as its weakest point component, therefore the following rule-of-thumb should be noted: 10% (where non-insulated) of the opening reduces the insulation by 50%.
