Thermal Insulation - An interesting subject!

What is Thermal insulation?

It is the process of reduction of the heat transfer - in simple words the transfer of thermal energy between objects of differing temperature between objects in thermal contact or in range of radiative influence. The heat flow is an inevitable consequence of contact between objects of different temperatures. Thermal insulation provides a region of insulation in which thermal conduction is reduced, creating a thermal break or thermal barrier.

Each thermal insulation material is having the insulating capability and is measured as the inverse of thermal conductivity (k). Low thermal conductivity is equivalent to high insulating capability (resistance value). In thermal engineering, other important properties of insulating materials are product density (ρ) and specific heat capacity (c).

ECA ® Thermal Insulation Flooring Block is a composite material made from Cement, Fly Ash, and Expanded Clay Aggregates (ECA ®). They are most preferred in place of thermal insulation sheet available in the market for the roofs and floors. Mass scale and small scale projects prefer ECA ® Thermal Insulation Flooring Block or thermal insulation mortar because its light in weight, manufactured from 100% inert light expanded clay aggregate which is durable, offers thermal insulation by low thermal conductivity coefficient (as low as 0.097 W/mK), offers soundproofing by high acoustic insulation, moisture impermeability, being incompressible under permanent pressure and gravity loads, not decomposing in severe conditions, fire resistance, a pH of nearly 7, freezing and melting resistance, easy movement and transportation and is introduced 1st time in India. It makes the product stand out as the best and most cost-effective thermal insulation material in the market today in India. The product is capable of offering excellent thermal insulation with a temperature difference of up to 11°C. (Standard conditions applicable)

When you are considering a product or a material for Thermal insulation roof or floor or for Building Insulation or for manufacturing heat insulation tiles or plastering the walls for thermal insulation in buildings, expanded clay aggregate is your preferred choice.

P.S.: We support the manufacture with the mix design and the manufacturing technology which can help them develop their own product line using expanded clay aggregate.
