Mylar Reflective Sheeting

Radiant heat transfer accounts for most indoor temperature surges in summer, a key pain point for construction purchasers planning roof & wall insulation upgrades. Xiashi Packing’s Mylar Reflective Sheeting is purpose-built to resolve this issue for all types of building projects. Its high-purity aluminum film carries ultra-low surface emissivity, deflecting nearly all infrared thermal radiation outwards and stabilizing indoor temperatures, which helps project contractors hit energy-saving targets during construction bidding and post-completion acceptance.

Product Specifications

Application Scenarios

This easy-to-process, high-performance radiant barrier is widely specified by distributors, general contractors and project buyers for multi-scenario thermal insulation procurement:

· Building Roofs and Walls: Specified for metal roof tiles, concrete roof and interior wall insulation bulk purchasing, cutting summer indoor heat gain to reduce long-term operational energy cost for property owners.

· Steel Structures and Warehouses: Preferred radiant barrier for industrial plant large-volume procurement, slashing monthly air-conditioning operating expenses for factory operators.

· HVAC Systems: Ideal bulk sourcing material for duct wrapping, minimizing heating & cooling energy loss in central air circulation pipelines.

· Cold Chain Logistics: Widely purchased by logistics suppliers as lining for insulated trucks and shipping containers to stabilize cargo temperature.

· Agricultural Facilities: Regularly ordered by farm contractors for greenhouses and livestock housing to sustain constant breeding & planting temperature environments.

Installation Guidelines

Correct installation of this Easy-maintainable membrane is critical for its reflective performance.

1. Maintain an Air Gap (Crucial): An air cavity of at least 2-5 cm must be left between the reflective sheeting and the roofing/wall substrate. This air layer acts as a thermal break, significantly optimizing the reflective efficiency.

2. Fixing: Unroll the sheeting and secure it flatly to the roof deck or framing using compatible insulation nails or staple guns. Ensure the surface is smooth and wrinkle-free.

3. Sealing Joints: Use aluminum foil tape to seal the overlaps between rolls to prevent heat from penetrating through gaps.

4. Pipe Penetrations: Wrap the seams around duct or pipe penetrations with matching sealing tape to maintain the integrity of the thermal barrier.

Core Advantages

With 40 years of full-chain manufacturing capacity, Xiashi Packing delivers stable supply for long-term bulk cooperation, and our Mylar Reflective Sheeting brings tangible procurement & construction benefits for distributors and project purchasers:

· Strong Radiant Heat Blocking & High Energy Saving Rate: Low-emissivity aluminum film reflects up to 90% outdoor radiant heat in summer and locks indoor heating inside in winter, cutting HVAC power consumption to help buyers pass green building assessment and lower overall project operating budgets.

· Dual Function: Heat Insulation + Moisture Resistance: The aluminum layer acts as a reliable vapor barrier to stop internal condensation, extend metal roof service life and reduce follow-up maintenance expenditure for project owners.

· Lightweight & Time-Saving Construction: Flexible, thin rolls are simpler to cut and deploy than rigid foam boards, shortening construction periods and lowering labor costs for contractors undertaking large-scale procurement.

· Eco-Friendly & Fully Recyclable: Zero harmful solvent formulation, non-toxic and fully recyclable. The material meets LEED green building standards, supporting buyers to obtain environmental certification points during project tender submission.

FAQs

Q: What is the difference between Mylar Reflective Sheeting and traditional foam insulation?

A: Traditional foam boards slow down conduction through their porous internal structure. In contrast, reflective sheeting reflects radiant heat away through its aluminum layer. For optimal energy efficiency, they are often used together in building systems.

Q: Is Mylar Reflective Sheeting effective for winter insulation?

A: Yes, absolutely. In winter, radiant heat generated indoors tries to escape to the outside. The aluminum layer reflects this escaping radiant heat back into the room, significantly helping to maintain interior warmth and reducing heating costs.

Q: Why is the air gap essential during installation?

A: Air is a poor conductor of heat. Without an air gap, the foil would be in direct contact with the roof panel, allowing heat to conduct through. The air gap cuts off this conductive path and allows the reflective layer to function at its peak efficiency.

Q: Do you offer custom sizes and private labeling?

A: Yes. As a direct manufacturing factory, Xiashi Packing Co., Ltd. provides full OEM customization. We support custom roll dimensions, weights, private brand labeling, and customized packaging to meet your specific market needs.
