Product Details
1. Product Description
Our Aluminum Foil EPE Foam Thermal Insulation is a high-performance radiant barrier and thermal insulation material designed specifically for modern building and construction applications. Combining a reflective pure aluminum foil (or metallized film) with a lightweight, resilient EPE (Expanded Polyethylene) foam core, this product effectively blocks up to 97% of radiant heat transfer. It serves as an exceptional insulation solution for roofs, walls, and floors, helping to maintain stable indoor temperatures, reduce energy consumption, and provide a reliable moisture and vapor barrier.

3. Product Advantages
High Radiant Heat Reflection: Reflects up to 97% of radiant heat, significantly lowering indoor temperatures in summer and retaining warmth in winter.
Dual Protection (Thermal & Vapor): The aluminum foil layer acts as a powerful moisture and vapor barrier, preventing condensation, mold, and dampness in building structures.
Lightweight & Easy to Install: Flexible and lightweight EPE foam makes cutting, handling, and installing quick and labor-efficient using basic tools.
Eco-Friendly & Non-Toxic: Made from environmental-friendly, non-hazardous materials that are safe for installers and indoor air quality.
Durability & Corrosion Resistance: Resistant to aging, tearing, and chemical degradation, ensuring long-lasting performance throughout the building's lifespan.
4. Frequently Asked Questions (FAQ)
Q1: Where is aluminum foil EPE foam insulation commonly used in buildings?
A: It is widely used under metal or tile roofs, in wall cavities, underfloor heating systems, attic spaces, and as a wrap for air conditioning ducts.
Q2: What is the difference between single-sided and double-sided aluminum foil?
A: Single-sided foil has aluminum on one side and bare EPE foam on the other, suitable for standard wall or floor applications. Double-sided foil has aluminum on both faces, providing maximum radiant heat reflection, ideal for open roof spaces and attics.
Q3: Does this insulation require any special tools for installation?
A: No special tools are needed. It can be easily cut with a utility knife or scissors and fixed in place using staples, tape, or adhesive.
