Environment responsive roofing – the future

Various materials have been tried in the past as thermal insulators with varying efficiency. Some of the roof cooling products include high-albedo paint, lime coating (that can be applied on visible patches on roof surface). While lime coating is cheaper, it requires repainting every six months. Application of high-albedo paint …

The high performance Noise Absorber

Armacell’s new acoustic form Armasound Super Silence Ductliner with Microban – achieves the desired noise absorption with lower insulation thicknesses compared to traditional acoustic insulation products. In addition, the acoustic foam has good sound barrier properties and its damping capabilities help reduce the transmission of structure-borne noise considerably. The elastomeric foam is dust – and fibre-free, highly flexible and water-repellent.

Heat Transfer Coefficient

Heat transfer coefficient is one of the parameters which has an influence when determining the insulation thickness needed to prevent condensation. Apart from preventing surface condensation, a reliable insulation system must also ensure that water does not collect within the insulation material. This is caused by processes of water vapour transmission.

Thermal insulation of buildings

The maximum energy demand – 50-70% – in a building is for conditioning (heating or cooling) the interiors. “Building Envelope” (roof, walls & floor) contributes to 60-75% of the heat gain/loss in a building and is the major contributor to the high load on air-conditioning. Insulation of building envelope has …

Cutting heat transfer, energy consumption

Rising energy costs has increased the need for energy efficient solutions in the building sector which accounts for 33% of electricity consumption in India. Innovative building envelope systems can effectively cut through the modes of heat transfer transmitted by way of conduction, convection and radiation. Heat transfer takes place from …
