What is Derin® Thermal Coatings ?

Derin® Thermal is a revolutionary paint and coating group that cuts energy costs up to 25% by reducing heating and cooling demands. This is a technology found by NASA technology exchange programme, independently tested and scientifically proven by Salford Thermal Measurement Laboratories. The most efficient way of reducing energy loss and saving your money is to have a good insulating paints and coatings that will provide you an excellent thermal performance, which also protects your home against moisture and air infiltration.

What does it do?

Saves on running time for heating and cooling equipment gives up to a 25% reduction in heat loss through internal and external walls, ceilings and roofs (or other coated surfaces such as pipes and ducting). Improves the overall performance of existing insulated buildings by over 50%. It blocks the extreme heat of the sun when applied to exterior walls. It improves the fire retardant properties of surfaces.

Heat Transfer

Understanding of Heat Transfer and Standard Insulation

Heat flows naturally from a warmer to a cooler space. In the winter, this heatlow moves directly from all heated living spaces to adjacent unheated attics, garages, and basements, or to the outdoors; or indirectly through interior ceilings, walls, and floors wherever there is a difference in temperature. During the cooling season, heat flows from outdoors to the house interior. To maintain comfort, the heat lost in winter must be replaced by your heating system and the heat gained in summer must be removed by your air conditioner. Insulating ceilings, walls,roof and floors decreases this heat flow by providing an effective resistance to the flow of heat. Unfortunately the environment rarely provides the ideal that we seek in our homes, hence the advent of central heating systems and air conditioningsystems. Until recently, apart from just accepting the loss of heat in the winterthrough our walls and roofs and in hot countries the flow of heat into the home there was little we could do, apart from spend large sums in trying to create a comfortable living environment. All the materials that are used in the construction of your home, business and buildings absorb and transfer heat. 80% - 95% of this heat is transferred! Heat ALWAYS flows from the warmer side to the cooler side by one or more of the following ways.

Global Warming Friendly, These coatings work from the reflection of the sun, that is why it benefits in hotter climates. Such as the Middle East, Africa and other tropical climates. Because of this sun reflected activated paints, energy is saved 25% to 45%.

Heat Transfer Types

Conduction - Conduction is the transfer of heat through a solid object. When one part of an object is heated, the molecules within it begin to move faster and more vigorously, when these moleculeshit other molecules within the object they cause heat to be transferred through the entire object.
Convection - Convection is the transfer of heat by the movement of a fluid (water, air, etc.) Inside of a wall cavity, air removes heat from a warm interior wall, then circulates to the colder exterior wall where it loses the heat.
Radiation - Any object will radiate heat to cooler objects around it by giving off "heat waves". This is a direct transfer of heat from one object to another, without heating the air in between. This is the same process in which the Earth receives heat from the Sun or a heater stove supplies heat to its surroundings. We have commonly used (mass) insulation such as Fiberglass, Cellulose, Styrofoam, etc. to slow down and resist R and U value, the heat transfer by way of conduction only; they do nothing for the heat transfer by way of radiation.

Mass insulation products work by trying to " trap " the heat in air pockets contained between the fibers in the product. Air is a good insulator against conduction but cannot stop radiant heat! Once the insulation becomes saturated with all the heat it can absorb the heat is then transferred on through the wall or ceiling. Besides of this , this conduction of heat transfer is between 5 % to 8 % of the total heat transfer into and out of a building That leaves between 92 % and 95 % of the total heat transfer to be dealt with, mostly by your air conditioner and heater.

In the winter time your interior walls and ceilings actually absorb a great deal of the heat that you generate with your heating system. This absorbed heat then flows outward through the walls and ceilings of your home into the colder outside air. This results in an Increased heat requirement and thus gives you higher heating bills. In Summer the heat gain increases interior temperatures and requires extended air-conditioning running times thus gives you higher cooling bills!

Standard insulation works by slowing down the RATE of transfer of the heat that has been absorbed by the walls, and roof or your home.

How does it work?

Derin® Thermal Paints & Coatings are developed to create thermal insulation property by their special formulations. Derin® Thermal Paints & Coatings create thermal insulation by reflecting and refracting radiant heat by using Thermilate ceramic microspheres which is approved by NASA and by insulating conductive type heat by including some special materials in their formulations.

Having a properly insulated home will save you energy, save you money as well as saving the environment.

Derin® Thermal Paints & Coatings reduces the insulative demands placed on conventional insulation which may have been poorly installed or have deteriorated due to dampness or age. The ability of Derin® Thermal Paints & Coatings to be easily and inexpensively applied to walls and ceilings which creates a thermal barrier is a superior method for the homeowner to utilize in order to maximize the energy efficiency of a home or building.

Upgrading the inner - wall or ceiling insulation in older or poorly insulated buildings can be an expensive, sometimes impossible task and one which may be too expensive to consider.

Whether you're a home-owner, building contractor; architect or engineer, you can make your paint by using Derin® Thermal Paints & Coatings, whenever you want to reduce heat loss in your buildings or reflect heat from the sun

Saving Energy & Money

There are two types of paint that can assist in saving energy in residential and industrial buildings. One relates to the reduction of the solar load to roofs and to exterior walls. The second one relates to interior room wall paints. These features are discussed below.

Derin® Thermal Exterior Paints and Coatings

Solar load reduction paints
When the sun shines on exterior surfaces of commercial and residential buildings, the solar load can be high enough in the summertime to require the use of excessive air conditioning in interior rooms in order to have comfortable conditions. If the exterior paints or coatings have reasonably good solar reflectivities, however, then the solar load being absorbed by the building would be reduced and the air conditioning required would also be less, thereby conserving energy.

Derin® Thermal Interior Paints and Coatings

Interior room heat transfer reduction paints
If the emissivities in the infrared region of interior wall coatings or paints are lower than ordinary paints, then the radiant hat transfer from the warmer outer walls of rooms would be less in the summertime, thus giving greater comfort to persons in the rooms because the radiant heat fluxes would be less, and there would be less warming of ambient room temperatures. Under these conditions , energy would be conserved because less air conditioning would be required. Under wintertime conditions, where furnace heating is normally required in residences and buildings, if the interior outer wall paints have lower emissivities than normal paints have, ambient room temperature cooling would be less and the comfort level of persons in the rooms would be greater because the radiation heat loss to cold, interior outer walls would be less, and the ambient air temperature reduction would be less. Thus, again, as in the summertime case, energy can be conserved if low emissivity interior wallpaints are utilized.

Where to Use Derin® Thermal Paints & Coatings?

For maximum benefit, use minimum two coats of Derin® Thermal Paints & Coatings together with the Derin® Thermal Primer.
Derin® Thermal Paints & Coatings produces a flat, slightly textured finish. If a final gloss or non-textured finish is required for the interior surfaces, apply two coats of Derin® Thermal Primer as an undercoat , before applying the gloss or flat coat.

Domestic, Commercial and Industrial buildings
Walls (Interior and exterior), ceilings, floors, roofs, metal wall cladding, hot air ducts, pipes, oil storage tanks, caravans and mobile homes, portakabins, garden sheds steel and GRP Hulls on boats and yachts
