Difference Between
Featherlite Blocks And Red Clay Bricks
| Sl.No | Parameter | Featherlite Blocks | Red Clay Bricks |
|---|---|---|---|
| 1 | Raw Materials | Cement, sand , water and air entraining agents | Locally available clay |
| 2 | Size | Length 600mm X Height 200mm/250 mm X thickness as per requirement with a difference of 25 mm 100mm/125mm/150mm/200mm | 225mm X 75mm X 100/125mm |
| 3 | Variation Size
|
1.5 mm (+/-)
|
5 mm (+/-)
|
| 4 | Compressive Strength (As per IS codes)
|
4 – 5 N/mm2
|
7 – 8 N/mm2
|
| 5 | Dry Density (As per IS codes) 1800 kg/m3
|
550-650 kg/m3 Its one-third of the weight of clay brick which makes it easy to lift and transport
|
1800 kg/m3
|
| 6 | Cost Benefit
|
For high rise buildings there will be reduction of dead weight which leads to saving in concrete and steel quantities.
|
Increase dead load of the building, So steel consumption becomes high. Also plaster & bricks joining cost high compared to Featherlite Blocks.
|
| 7 | Fire Resistance (Heat Resistance)(on 8″ Wall)
|
Up to 4 Hours
|
Around 1 Hour
|
| 8 | Moisture Content
|
Gradualy decrease up to 4 to 6 % in 2 to 3 years
|
Never gets less than 10 to 13 %
|
| 9 | Quality of End Product
|
Factory made product. So the quality of end product is consistent and good
|
Locally made product. Quality depends on various parameters like quality of soil used,process of manufacture etc.
|
| 10 | Sound Insulation
|
High Sound absorption / insulation as compared to bricks
|
Normal
|
| 11 | Energy Saving
|
Low thermal conductivity (0.24 Kw-M/C) helps in saving electricity costs 30% for heating and cooling of house.
|
High thermal conductivity (0.81 Kw-M/C). So no cost savings.
|
| 12 | Environmental Friendliness
|
In the Manufacturing process of Featherlite Blocks only 50% of natural available material used & 50% air bubbles is present in it by it’s mfg design.
|
One sq ft of carpet area with clay brick walling will consume 25.5 kg of top soil (approx). It actually damages environment
|
| 13 | Internal and External Plaster
|
As these bricks have dimensional accuracy, the internal and external plaster thickness become very low
|
Requires thick plaster surface as there are variations in the dimensions and due to uneven surface.
|
| 14 | Joining Process
|
Chemical mortars can be used for joining the blocks. This reduces the material consumption of cement and also avoids curing process
|
Traditional mortar needs to be used and the brick work should be cured at least for 7 days before plastering
|
| 15 | Availability
|
Availability of material in all season with suitable prices.
|
No production in rainy season, so high price variation and unavailability during monsoon.
|
| 16 | Thermal Insulator
|
Featherlite Blocks are very high thermal insulator, if cooling is a major component of any building then energy expenses will be saved for entire lifetime.(0.21-0.42 W/m K )
|
It has low thermal insulation as compare to Featherlite Block ( 0.6 – 1.0 W/m K )
|
| 17 | Tax Contribution
|
Contributes to government taxes in form of GST
|
No tax contribution
|
| 18 | Water Sustainability
|
Due to its closed matrix structure it allows water to penetrate the surface very slowly. ( 5.6- 7.2%)
|
Water absorption sustainability is very low.(13- 14%)
|
| 19 | Range of Application
|
They are suitable for non load bearing or RCC structure in partition wall
|
They are useful in both load bearing and nonload bearing structure
