Mattresses are very flexible. They will essentially retain thickness while conforming to any irregular shape. Retention of fibers by wire mesh prevents cracking or breaking of mattresses.

BENEFITS OF DRW/ECOROCK  INSULATION PRODUCT

Incombustible Good acoustic properties

Glass wool Insulation is one of the most widely used forms of insulatino world-wide because of its thermal and acoustic insulation properties, light weight, hogh tensile strength and exceptional resilience. Glass wool is the most dominant type of insulation used in applications with service temperatures between -50oC to +250oC, with a world-wide market size of approx. US $7 billion.
Glass wool consist of fine, long, inorganic fibers bonded together by high temperature binder. Ther fibers (each of approx. 6 - 7 microns diameter) are distributed in such a way as to trap millions of tiny pockets of air in the product, thereby creating its excellent thermal and acoustic insulation properties. the product is light gold in colour and its superior tensile strength and resilience makes the product ideal for applications in which there will be vibration, jolting or high compression. The light weight and handleability of Glass wool also offers significant advantages during transport and installation. In addition, Glass wool is chemically inert and has no impurities such as iron shots, sulphur and chloride. The product is non corrosive to metal and does not support mold grow.
The use of Glass wool for the thermal insulation of external walls and ceiling has been shown to reduce energy consumption by 20% to 30%. Glass wool is manufactured from widely available and renewable raw materials and provides environmental benefits in terms of resource saving and energy saving in every stage from pre-manufacturing to end use. The Glass wool is formed into products with various thickness and densities.

Thermocole /EPS is available in the form of “ND” & “TF” quality. Application : G and K Insulation also provide Thermocole Insulation for Cold Insulation. Effective and efficient insulation for low temperature appliances i.e. cold storage, Industrial Refrigeration, Refrgerated vans, sound Insulation, Commercial & Household air Conditioning.

Expanded Polystyrene is Flexible High Strength Polystyrene slabs used for Insulation of flat roofs, Floor, Structures, below ground, cavity walls , pitched roofs and Agricultural Buildings.

The Ceramic Blanket is made up of long cerachem fibers of alumina and silica constituents and zircon
Application : Crude Oil , Reformer & Pyrolysis heating linings, High temperature pipe ducts & turbine Insulation, Treatment Furnaces, Ovens & Stack linings.

Loose Mineral Wool is a high temperature insulating fibers processed from natural Rocks of selected quality. The Loose Mineral Wool having exceptionally long fibers and superior technical properties essential to meet severe service condition. Loose Mineral Wool can be used for insulating equipments, tanks, pipelines, ovens, furnaces, and buildings. The properties of Loose Mineral Wool includes incombustibility , water repellent, odorless, non-corrosive , non-settling, fire resistant, heat resistant and sound absorption.
