The main advantages of a PVC ceiling derive from the properties of plastics, for example:
- PVC is a non-hygroscopic material and does not absorb water, the advantage of this in a bathroom is that steam from the bath or shower will not be absorbed into the ceiling. So unlike a traditional plastered ceiling which can go mouldy from steam absorption, PVC ceilings will not go mouldy.
- PVC ceilings are easy to clean using any household cleaners or a damp/dry cloth. They just need a quick wipe from time to time to keep them looking like new.
- PVC ceilings do not need painting. No more weekends spent painting and repainting bathroom ceilings with expensive paint. Plastic ceilings come in the chosen colour ready to install.
- Easy to install- Plastic ceilings are easy to install with limited tools. A competent DIYer can install a plastic ceiling in a couple of hours and can be installed over an existing plastered or artexed ceiling.
- Can be installed with downlights and is a great way of concealing wiring. Downlights, also known as spot lights, are popular upgrades in bathrooms and kitchens but require additional wiring runs and holes to be drilled in the ceiling. PVC ceilings are perfect for covering over the damage to the existing ceiling caused from the downlight installation, so no need for the ceiling to re-plastered skimmed and painted.
- PVC ceilings can be installed on a wooden or metal framework.
- PVC ceiling can be used as a suspended ceiling
- PVC ceilings are inexpensive to make and install.
- PVC ceilings are durable and sturdy.
