Roof Tiles, Floor Tiles and Wall Tiles

Tiles are clay products like brick but are thin. Depending upon their use, building tiles may be further classified as:

ROOF TILES

Roofing tiles are used to cover sloping roofs. They are supported on wooden reapers. Sometimes light gauge steel or steel rods are also used as reapers. After supporting on reapers these tiles should be strong enough to take load of a man safely. The tiles should he leak proof. Normally these tiles are having curved surface having ribbed sections, so that with thin section they are sufficiently strong to resist the load. However many times flat tiles are used under curved/ribbed tiles.
These tiles are not subjected to load directly. They serve in reducing adverse thermal effects. Corrugated tiles satisfy the requirements of appearance and leak proof but they can be easily blown away by wind.

PROPERTIES OF ROOF TILES

[1] They should not absorb moisture more than 20% by weight.

[2] They should give pleasing look.

[3] They should be capable of taking load of a man safely, after they are supported on reapers.

[4] They should be durable.

[5] They should be uniform in shape and size.

[6] Warpage should not exceed 2% along the edges and 1.5% along the diagonal.

 

FLOOR TILES AND WALL TILES

These tiles are manufactured by burning pressed green tiles twice. First they are burnt at 700°C. Then they are dipped in the glaze solution and again burnt at 1250°C to fuse them with glaze. The thickness of these tiles vary from 15 to 20 mm. These tiles are flat and they have pleasing appearance. There are two types of flooring tiles:

PROPERTIES OF FLOOR & WALL TILES

[2] Tolerance for thickness should be ± 2 mm.

[3] Should be uniform in shape and colour.

[4] They should be sound, hard and durable.

[5] They should have very low percentage of water absorption.
