Building Insulation

Energy efficiency in buildings is achieved through a multi - pronged approach involving adoption of architectural principles responsive to the climate of the particular location by combining efficient insulation with robust structural design. Implementation of energy-efficiency in building systems is almost entirely dependent on effective Thermal Insulation of the building envelope.

India is quite a challenge in this sense since there are as many as six major climate zones:

  1. Cold and sunny
  2. Cold and cloudy
  3. Warm and humid
  4. Hot and dry
  5. Composite and
  6. Moderate

Translation of optimum architectural design in the Indian context therefore poses a major challenge in proper choice and deployment of Insulation, Vapour retarder, Weather protection and aesthetic finishing.

Design of energy efficient envelope is a matter of deep understanding of Building Physics and thorough knowledge of Materials Sciences. Lloyd Insulations have led from the front in these branches of science.

Thermal insulation in buildings plays an important part in achieving thermal comfort for its occupants. Insulation reduces unwanted heat loss or gain and can decrease the energy demands of heating and cooling systems.

In addition to a wide choice of Thermal envelopes, Lloyd Insulations provide complete solutions for scientific thermal Insulation of HVAC system elements like chilled water Refrigerant lines, supply and Return air ducting and Air Handling units a hot water plumbing to provide comprehensive energy efficiency to the built environment.

We have joined major players in the Building Sector in India, in co-ordination with energy experts, to draw up ENERGY CONSERVATION BUILDING CODE (ECBC). This aims to specify norms for insulation resistance requirements for buildings servicing various specific functions in various climate zones.

Whether in Industry, commerce or in residential environment, thermal comfort has become a vital necessity. Employee productivity is directly linked to his workplace environment.

Enclosures which operate without any cooling systems are totally dependant on Insulation coupled with adequate ventilation for achieving thermal comfort.

In spaces which are air-conditioned to face summer conditions, high heat ingress greatly increases the load required on the HVAC equipment to remove the above ingress of heat - which means:-

  • High energy cost for running the HVAC system and
  • Higher running time and, hence wear and tear of the HVAC equipment
  • Insufficiently or poorly insulated building would also mean necessity to install HVAC equipment of much higher capacity than what would be adequate if proper thermal insulation had been provided. This would mean higher first cost of the project itself.

In other parts of the year, insulation duty would also include extreme winter ambient conditions and the concurrent need for achieving thermal comfort in the building interior by heating.

Under winter conditions, a major hazard is the risk of condensation within the system itself or on the inner surfaces of un-insulated or insufficiently insulated building elements. Detailing the Insulation system design would involve proper placement of Vapour Retarder and very careful attention to potential heat bridges and Cold spots.

Major contributors to energy balance in buildings are the roofs. Roofs are composed of Reinforced Cement Concrete (RCC), sheets of fiber Reinforced Cement sheets or Plain / Coated Metal profiles. Apart from addition of insulation value to such elements, it is necessary to add thermal capacity as well - to be able to dampen the effect of cyclical temperature variations so very common over a typical Indian summer day.

Thermal insulation, by retarding heat flow, delivers the following benefits to a building enclosure:

  1. Helps maintain temperatures as perceived by the occupant to be within his limits of tolerance.
  2. Reduces over-all cost of heating or cooling by cutting down energy consumption.
  3. Reduces capacity of capital equipment to be installed for HVAC duty by cutting heat loss or heat gain to be compensated.
  4. Keeps the temperature of the inner surfaces of buildings within acceptable limits to reduce possibility of their acting as “Radiators” causing added thermal discomfort in summer and possible condensation in winter.
  5. Provides fire protection to metal structures.
  6. Reduces break-in of external noises and absorbs internally generated Noise.

Thermal insulation is specified and applied to fulfill any one or combination of the above functions.

Materials- Importance of physical & chemical properties

As can be appreciated, the most important single requirement is that the materials deployed in the insulation system should remain in place and continue performance of their assigned role over the expected life of the building. This stipulation would require that each material should be unaffected by exposure to the environmental media for the entire life span of a building.

Lloyd insulations offers a wide range of materials, each of them developed, tested and validated to deliver the best value to the end user.

The ROCKLOYD range of bonded mineral wool combines excellent insulation value with total fire safety. Its fibrous matrix affords excellent acoustical and Noise control properties as well. It is offered in all possible forms - Slabs, flexible Mattress, performed Pipe Section or sprayable formulations.

ISOLOYD NILFLAME, SUPERFOAM, LLOYD FOAM and SUPERTHEM represent the higher end of thermal efficiency, while delivered excellent structural strength properties. These closed cell Rigid Urethane Foam insulating materials resist vapour migration and water ingress.

LLOYD PANEL Systems provide the ultimate value in building insulation. They provide a one step solution towards excellent Insulation Value, Extraordinary Structural Strength and the highest levels of aesthetic finish to a building. Exciting opportunities are offered to Architects and designers to extract maximum benefit to the end user in applications like commercial complexes, large Industrial buildings and public buildings like Airports, stadia and convention centers.

Lloyd Insulations manufactures each of the above materials in a network of plants, located in different parts of India to service customer requirements promptly and economically.

Each of the plants is equipped with relevant laboratory and testing facilities to assure quality at each step.

Having met and exceeded specified requirements of some of the most demanding users and consultants, our products enjoy the benefit of acceptance by every leading specifier in the field.
