Overdeck insulation on metal roofs, insulates hailstorm sounds


Home » Overdeck insulation on metal roofs, insulates hailstorm sounds


Yesterday (07.02.19) there was a scary hailstorm in Noida once again highlighting the need for overdeck insulation on metal roofs . Though the kids enjoyed the snowy aftereffects of the hailstorm, it must have been really scary under a metal roof that Noida is dotted with. With legal restrictions on additional floor space, metal sheds on the top floor are a no-brainer for the free additional floor space. However, it can be very uncomfortable for people working there in summers & winters. During a hailstorm like yesterday, it can be really scary underneath the metal roof due to the amplified impact sound of the hail stones hitting the roof.

How can one overcome this problem? We have successfully executed overdeck insulation on metal roof in Delhi in a Kids Play zone. The results have been to the total satisfaction of the client. They reported that the roof treatment of overdeck insulation of metal roof, reduced the air conditioning load very substantially. This saving was estimated through our U Value calculator as over 40% in peak summers. Secondly, it totally prevented the wetting of the interiors due to moisture condensation droppings during cold nights. Thirdly, it prevented the scary sound of hail or rain drops hitting the metal roof . For more details checkout https://www.reliableinsupacks.com/our-services/roof-insulation/

A mechanical engineer from IIT, Kanpur, through the 30 years of my entrepreneurial journey, I have learned that we tend to be unaware of many “Staring at our face” things unless trained to interpret them at the conceptual level. The “Building” decision-makers are unaware of the “Building-Physics” as this is not dealt with in a structured fashion at the college level. Yet they are at the helm of a segment that accounts for 35% of national energy consumption and generation of 40% of Green House Gases. This blog site is my humble effort at making them”conceptually aware” of facts they already know quite well.
