Brickbat coba weighs about 1,970 kg/m³. Here is what that means per square metre of terrace and sunk area, for a whole tower, and how much a lightweight fill takes off.

Why Perlite India exists: our founder on retiring brickbat coba and building lighter, cooler, longer-lasting buildings.

The greenest building material is often the one you do not need. How lightweight perlite concrete cuts dead load, cooling energy and repairs, and supports green building goals in India.

Sun-facing walls soak up heat all afternoon and give it back to the rooms at night. A perlite insulating plaster adds insulation to the wall itself, in the same step as plastering.

Hospitals carry heavy equipment, run air-conditioning round the clock and cannot compromise on fire safety. Why perlite concrete fits hospital floors and roofs, with projects at Jupiter Hospital and Chellaram Hospital.

Foam boards have the lowest k-value on paper. But a roof is a system: boards need a screed on top, joints, a slope and fire safety. How they compare with a poured perlite concrete insulation.

Perlite India has worked with many of the city's leading developers, IT companies and resorts. Roof insulation, terrace slopes, floor screeds and sunk fills in Pune and PCMC.

Podiums carry landscaping, driveways, fire tender paths and deep fills to level. Perlite concrete fills give the levels and slopes you need with far less dead load than soil, brickbat or plain concrete.

Many builders have moved from brickbat coba to AAC block coba. Here is how AAC block pieces compare with a poured perlite concrete fill on weight, heat, voids, slope and finish.

White reflective coatings are cheap and quick. Insulation costs more but works day and night, in every season, and does not wash off. When to use each, and why the best roofs use both.

Hospitals, an airport, IT parks, factories, resorts and leading developers. The clients and projects where Perlite India has delivered perlite lightweight concrete.

EPS bead concrete is a popular lightweight filler, but it carries plastic beads into your building. How it compares with perlite concrete on fire, finish, segregation and use.

Perlite concrete is lightweight, heat-insulating concrete made with expanded perlite. What it is made of, the density range, thermal conductivity, where it is used and where it is not.

Commercial floors on PT and RCC slabs often carry a thick mortar bed under the tiles. How a lightweight perlite concrete screed cuts that weight and gives a hard, level base for any finish.

What to fill a sunken toilet or bathroom slab with. A plain comparison of brickbat, sand, cinder, foam, EPS and perlite concrete on weight, settlement and finish.

Foam concrete and perlite concrete both cut weight, but they behave very differently on site. A practical comparison of shrinkage, surface finish, screw holding, fire and insulation.

Brickbat coba is heavy, slow and depends on brick quality and skilled labour. Here is how perlite lightweight concrete replaces it on terraces and sunk areas, with the weight saving worked out.

A bare RCC terrace can turn the top floor into an oven. How heat moves through a roof, why brickbat coba does little to stop it, and how heat-insulating perlite concrete cuts the heat.
