PEB Insulation Sheet Manufacturer in India

Here is what happens inside an uninsulated PEB shed:

1. The metal roof absorbs solar radiation all day. Surface temperature climbs above 70°C by 2 pm.
2. Heat radiates downward into the building. Shop floor temperature rises 8 to 12°C above ambient.
3. Workers slow down. Heat related productivity loss in Indian factories is well documented.
4. Machinery overheats. Electronics fail faster. Lubricants thin out.
5. Stored goods (FMCG, pharma, electronics, food) degrade.
6. AC load rises sharply if the building is conditioned. Power bills jump 30 to 50 percent.
7. During monsoon, the cool underside of the metal sheet collides with warm humid interior air. Condensation forms and drips down onto goods, machinery, and the floor.
8. Rain on bare PEB metal roof creates noise above 85dB, making conversation impossible.

A properly installed reflective PEB insulation layer addresses every single one of these problems with a single product.

A TigerShield™ PEB insulation sheet has three functional layers:

1. Top layer. Pure aluminium foil with 97 percent reflectivity. Bounces radiant heat back toward the roof before it can transfer into the building.
2. Core layer. Closed cell polyethylene bubble film. Traps still air inside thousands of sealed bubbles, which slows conductive and convective heat transfer.
3. Bottom layer. A second aluminium foil layer (in double foil variants). Reflects any residual heat back, and acts as a vapour barrier against monsoon condensation.

Combined, the sheet works as a three way thermal barrier in a single roll that weighs less than 5 kg and installs in under an hour for a typical 1000 sqft section.

There are three standard installation methods for PEB insulation. The right one depends on whether you are insulating a new build or retrofitting an existing structure.

Method 1: Over Purlin (New Construction, Preferred) The insulation roll is laid flat across the purlins, foil side facing down. The metal roof sheet is then fixed on top. This gives the cleanest finish, full coverage, and the best thermal performance because it eliminates thermal bridging at the purlin contact points.

Method 2: Under Purlin (Retrofit, Most Common) If your PEB is already built and you want to add insulation, the sheet is stapled or nailed to the underside of the purlins. The insulation hangs below the structural members. Easy to retrofit, lower disruption, slightly lower performance than over purlin.

Method 3: Sag Method (Between Purlins) The insulation is loosely draped between purlins so that it sags slightly into the cavity. Used when you need to maintain visible purlin lines from inside (architectural exposed purlin look).

For most Indian PEB sheds we recommend Method 1 if it is a new build, or Method 2 if it is a retrofit. Both work. Our team can advise based on your site photos.
