Smart Reflective Insulation for PEB Structures and Metal Sheds
Carmika Classic, under the Carmika brand by Shish SmartBuild, is a high-performance reflective bubble insulation designed for India's demanding construction environments -- particularly Pre-Engineered Buildings (PEB) and metal roofed industrial sheds.
Manufactured by laminating two highly reflective surfaces (pure aluminum foil) over one or two layers of polyethylene air bubbles, Carmika Classic forms a durable radiant barrier that reflects up to 97% of solar heat, minimizing thermal gain inside buildings.
Engineered for thermal efficiency, moisture control, and installation ease, Carmika Classic offers excellent indoor comfort improvement while reducing energy costs across warehousing, logistics, agriculture, and residential projects.
At Shish SmartBuild, we don't just insulate -- we build smarter, cooler, and more sustainable structures for India's future.
Key Features
High Solar Reflectivity (>=97%)
Protects interiors by rejecting radiant heat before it penetrates the building envelope.
Effective Thermal Insulation
Enhances energy efficiency by reducing cooling and heating requirements.
Integrated Moisture and Vapor Barrier
Prevents condensation formation under metal roofing systems.
Lightweight and Flexible
Easy to transport, cut, and install, saving construction time and labor.
Durable Laminated Construction
Tear-resistant, puncture-resistant, and reliable across extreme temperatures.
Safe for Installers
No harmful fibers, dust, or VOCs -- ensuring a healthier worksite environment.
Applications
Pre-Engineered Buildings (PEBs)
Roof and wall insulation for energy savings, condensation prevention, and thermal comfort.
Industrial Warehouses
Metal shed insulation to control heat ingress and protect goods.
Logistics Centers
Insulation for distribution hubs and logistics storage units.
Metal Shade Structures
Poultry houses, dairy shelters, agriculture storage sheds, greenhouse structures.
Residential Villas and Farmhouses
Under-roof reflective barriers for energy-efficient housing.
Agriculture and Farming
Insulated roofing for cold storage, greenhouse tunnels, and farm produce protection.

Installation Guide
Recommended Tools:
1 Under New Metal Roofing Installation
- Unroll Carmika Classic directly over purlins or trusses before fixing roof sheets.
- Allow minimum 50 mm overlap between adjacent rolls.
- Fasten insulation securely using staples or cap nails at 300-450 mm intervals.
- Tape all seams and overlaps with reflective foil tape for complete radiant barrier continuity.
- Install metal sheets directly over the insulation using standard roofing fasteners.
2 Retrofit Installation in Existing Metal Roofs
- Fix lightweight framing (battens, wires, or rods) below existing roofing.
- Drape Carmika Classic under existing roof panels maintaining minimum 20-50 mm air gap above insulation.
- Secure using fasteners and foil tape to create a tight, reflective shield.
- Avoid sagging to maintain an effective air space.
3 Wall Applications
- Staple Carmika Classic vertically or horizontally to wall studs.
- Ensure tight sealing at edges, overlaps, and openings.
- Cladding or internal walls can be installed over insulation if needed.
4 Installation Tips
- Always install reflective surface facing the air gap for maximum efficiency.
- Install with air gaps wherever possible to boost R-value.
- Avoid tearing or puncturing the insulation during handling.
- Wear protective eyewear and gloves if working overhead.
