Under Deck Insulation Manufacturer in India

Here’s what happens inside an Indian factory or warehouse without under deck insulation:

1. Roof absorbs solar heat all day. Metal roof surface temperature crosses 70°C by 2 pm. RCC slab radiates retained heat well into the evening.
2. Heat radiates downward. Shop floor temperature rises 8–12°C above ambient outside temperature.
3. Productivity drops. Workers slow down. Heat-related fatigue is well-documented in Indian manufacturing studies.
4. Equipment fails faster. Electronics, machinery, and lubricants degrade in sustained heat.
5. Inventory damage. FMCG, pharmaceuticals, electronics, and packaged food spoil or degrade in storage.
6. AC bills explode. If your building is conditioned, cooling load rises 30–50% in summer months.
7. Monsoon condensation. The cool underside of metal roofing meets warm humid interior air. Droplets form and rain down onto goods and machinery.
8. Rain noise. Bare metal roofs amplify monsoon rain to over 85dB — loud enough to make voice communication impossible.

A properly installed under deck insulation layer addresses every single one of these problems with one product, one installation, one supplier.

A TigerShield™ under deck insulation sheet is built in three functional layers:

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

Combined, the sheet works as a three-mode thermal barrier — reflective, conductive, and convective — in a single lightweight roll that installs in under an hour per 1,000 sqft section.

The right installation method depends on your existing roof type and how exposed the underside is. Our team can recommend based on site photos.

Method 1 — Direct Staple Under Purlin (most common for metal-roof PEB) The insulation roll is unrolled across the underside of the purlins, reflective side facing down. Fixed with a heavy-duty staple gun or roofing nails. Fastest installation method. Best for metal-roof PEB and tin-shed factories.

Method 2 — Spacer + Fastener (for RCC / concrete slabs) Aluminium or PVC spacers are first fixed to the concrete underside at 600mm intervals. The insulation sheet is then fastened to the spacers, creating a small air gap that boosts thermal performance by another 15%. Required for RCC slabs because direct contact reduces reflective performance.

Method 3 — Wire Mesh Suspension (for large open spans) A wire mesh grid is first stretched across the underside of trusses. The insulation is then draped over the mesh, with the mesh supporting any sag. Used in warehouses with very wide column spacings where direct fixing isn’t practical.

For most Indian factory sheds and warehouses, Method 1 (direct staple) is the right choice. For commercial buildings with RCC roofs, Method 2 is standard.
