Excerpts from the interview:


What are the evolving technological trends across the roof insulation market in India?

Buildings in India had been without any additional roof insulation material. Traditional buildings in the Thar Desert of Rajasthan achieved the necessary protection against solar heat during summer through building design involving thick walls, high roofs and sun shaded windows as well as building orientation vis-à-vis sun path.
Insulation of buildings to provide protection against heat gain during summers is a recent phenomenon and traditional materials for building insulation have been bulk insulation materials like Glass wool or Rockwool that provide insulation by taking care of transfer of heat through conduction and convection mode of heat transfer.
Latest entrant in the field of heat insulation are products based on Principle of Reflective Insulation i.e. block more than 95 per cent of the heat radiations from solar heated roof with the help of an aluminum sheet that would reflect 95 per cent of the radiations.
The switch over from use of bulk insulation for stopping heat gain in buildings to Reflective Insulation happened about a decade back with the induction of double sided Aluminium Foil Radiant Heat Barriers from Tasman Insulation, New Zealand. The company was acquired by M/s Fletcher Insulation, Australia subsequently. Now, we can see the induction of many variants of Radiant Heat Barrier products like Bubble Insulation products and Bulk Insulation products with Aluminum foil facing.


How much growth do you foresee across the roof insulation market in India? Tell us about the main growth drivers?

The growth in infrastructure sector had been badly affected by the slowdown of economy over past couple of years. However, the worst seems to be over and economy is already showing signs of recovery. With all new buildings being designed keeping in mind the requirements of Energy Conservation Building Code (ECBC 2007) norms laid by the Bureau of Energy Efficiency (BEE), the need for insulation material for new construction is bound to see exponential growth.


How can roof insulation ensure better energy efficiency at buildings or factories?

An energy efficient building would have minimal energy requirement to provide good working environment i.e. temperature, humidity and lighting conditions conducive for stress free working conditions for workers inside building. The impact of Solar heat was scientifically studied at Florida Solar Energy Centre (FSEC). Two principal conclusions from their testing were:

• Radiant heat transfer accounted for 87 per cent of the heat transfer down through the roofing &
• Radiant heat barriers were found to be much more effective for reducing summer heat gain inside the building in comparison to bulk insulation.

Installation of Radiant Heat Barrier Roof insulation helps in substantial reduction of heat gain as well as improved lighting conditions. The power savings in air-conditioned buildings can be as much as 25 per cent in case of day only use buildings while in case of buildings with round-the-clock AC requirements, the savings can be as much as 15 per cent. In un-conditioned buildings, the working environment improves with reduction of indoor temperature by as much as six to eight degrees.
Do customers still look at only initial costs while selecting roof insulation or understand the lifecycle benefits through energy efficiency?

Customers in India are sensitive to input cost while selecting the insulation material. However, with the growing awareness of the insulation requirements amongst building/architect consultants, all the stakeholders are getting educated about the lifecycle benefits of insulation.


What is the future business strategy of Macmillan Insulations?

Although, Macmillan Insulation has pan India foot print, however bulk of our clients were from Northern and Western India. Now we intend to expand with special emphasis on Southern and Eastern India.


Going forward, does Macmillan Insulations intend to launch any new services or increase focus on any existing segment?

Our immediate stress would be on our existing segment. However, we do intend to diversify in near future.
