POLY VINYL CHLORIDE(PVC) – ADVANTAGES AND DISADVANTAGES
PVC is Polyvinyl Chloride.
– ADVANTAGES OF PVC DOORS AND WINDOWS
i. PVC doors and windows offer high resistance to impact, weathering and fire.
ii. They provide highest standard for quality, durability and efficiency.
iii. Since they are fungal resistant, they do not require either painting or varnishing.
iv. They are impervious to moisture.
v. The cell design of PVC reduce heat loss and conduc- tivity, making them great insulators.
vi. Their smooth surface does not need any special care or maintenance
vii. Light in weight, easy to handle and transport.
viii. They can meet all demands. All desired shapes are available in a variety of colours and with different finishes.
ix. They are flexible so that doors and windows can be made in many variety of shapes and sizes.

ii. They are not safe.
iii. There are possibilities of cracks while driving screws during installation.
iv. The appearance of plastic doors and windows is not as pleasant or decorative as wooden ones.
ADVANTAGES OF PVC PIPES
i. Light in weight, easy to handle and transport.
ii. Durable and unaffected by fungi & insects.
iii. Good electrical insulators.
iv. They are available in required sizes and shapes.
v. Free from corrosion.
vi. They are cheaper than A.C pipes, Galvanized Iron pipes and Cast Iron pipes.
vii. Placing, bending and installation are easy.
viii. Have adequate strength and are resistant to shock.
ix. Highly resistant to acidic water.
x. PVC pipes resist vibration better than steel.
DISADVANTAGES OF PVC PIPES
i. Have low resistant to heat.
ii. Expansion is high.
iii. Some types of PVC impart taste and smell to water.
iv. Difficult to obtain PVC pipes of uniform composition.
