Tradsark Underfloor Heating Aluminium Grid Film – 105µm, 50m Insulation Foil

Introduction

Modern homes and commercial buildings demand high comfort and energy efficiency from underfloor heating systems. The performance of an underfloor heating system depends not only on the heating equipment itself but also on the choice of underfloor heating insulation film. Tradsark 105µm Aluminium Grid Underfloor Heating Film combines durability, precise grid markings for installation, and excellent heat reflection, making it an ideal solution for efficient heating and energy savings. This article explores the advantages and applications of Tradsark aluminium grid underfloor heating film from material, installation, energy efficiency, longevity, and safety perspectives.

1. Material Advantages and Multi-layer Structure

Tradsark underfloor heating film is made from a PP/AL/LDPE multi-layer composite, providing lightweight yet robust insulation. Its metallized surface reflects heat efficiently, reducing downward heat loss and delivering more warmth to the indoor space, which enhances heating efficiency.

  • Moisture Protection
    The film protects polystyrene insulation boards from moisture in the concrete screed, preventing mold, deformation, and prolonging the lifespan of the underfloor heating system.

  • Tear and Wear Resistance
    With a thickness of 0.105 mm, the film can withstand foot traffic and concrete pouring during installation, ensuring durability and reliability.

  • Low Vapor Diffusion
    The low vapor permeability of the Tradsark film prevents moisture from seeping into the insulation boards, keeping the floor dry and maintaining indoor comfort.

2. Installation Convenience and Efficiency

Tradsark aluminium grid film features 10×10 cm grid lines with additional 5×5 cm sub-grids, allowing installers to accurately position heating pipes and clips.

  • Large Roll Size for Maximum Coverage
    With a width of 102 cm and a length of 50 meters, the roll covers a large area with fewer seams, saving time and labor costs.

  • High Compatibility
    Suitable for both electric and water-based underfloor heating systems, compatible with tile, wood, laminate, and other floor finishes.

  • Installation Tips

    1. Place the film with the grid side facing up for proper pipe alignment.

    2. Seal overlaps with aluminium tape to prevent heat loss.

    3. Extend the film along wall edges to reduce thermal bridging.

3. Energy Efficiency and Indoor Comfort

The metallized reflective layer of Tradsark film directs heat upward, allowing rooms to reach desired temperatures quickly and efficiently.

  • Even Heat Distribution
    The film ensures uniform heat transfer across the floor surface, avoiding hot and cold spots, and increasing overall comfort.

  • Energy Savings
    Reflecting heat effectively reduces wasted energy, lowering operational costs and contributing to energy-efficient building design.

  • Versatile Applications
    Can be used not only under floors but also near radiators, walls, or corners, ensuring uniform heat distribution and reducing energy loss.

4. Safety and Environmental Benefits

Tradsark aluminium grid underfloor heating film is free from glass fibers and hazardous substances, ensuring safe installation and long-term use. Its recyclable materials comply with modern environmental standards.

  • Non-toxic and Safe – Safe for installers and end users.

  • Fire-resistant – Meets international building safety standards.

  • Recyclable – Supports green building practices and sustainable construction.
