ECOSUNLIGHT
Day lighting is the controlled admission of natural sunlight and diffuse into a building to reduce electric lighting and save energy. It provides true color rendition, helps create a visually stimulating and productive environment, while reducing as much as one-third of total building energy costs.
Eco Sunlight Tubular Skylights use a roofmounted light-collecting dome to collect sunlight from various angles throughout the day. The light is reflected through a tube and diffused into a room through a fixture that looks like a standard recessed light. Because of the shape of the “scoop” at the top, tubular skylights can draw light regardless of the sun’s
Estimated equivalent performance
| Tube Size | Area Coverage | Lumen | Equivalent Wattage Output | Maximum Light Tube Length |
|---|---|---|---|---|
| 10" | Up to 150 Sq. ft. | 3,750 lm | Up to 300 watts | 18" |
| 13" | Up to 300 Sq. ft. | 6,500 lm | Up to 500 watts | 20" |
| 21" | Up to 700 Sq. ft. | 13,900 lm | Up to 1450 watts | 20" |
MICROSILICA
- Micro Silica, a mineral composed of ultrafine amorphous spheres of silicon dioxide (SiO2), is used as an additive for a stronger durable concrete structure.
- Advance Micro Silica is much finer than Ordinary Portland Cement (OPC). It is a pozzolanic material primarily consisting of natural fine grained densified particles of silica (SiO2) with bulk density ranging from 500~750 Kg/m3.

technical dosage range
| Type of Application | Percentage of Dosage* (%) |
|---|---|
| Normal Concret | 4-7 |
| Self -Compacting Concret | 4-10 |
