Introduction to Underfloor Heating Reflective Film
Underfloor heating reflective film is a functional roll‑film laid beneath heating pipes for water‑based or electric floor‑heating projects. It helps reflect heat upwards to the living space, lowers downward heat loss to the base layer, and may improve heating‑system efficiency.
A wide range of base‑material combinations can be manufactured, suitable for residential apartments, commercial buildings, warehouses and large‑scale construction sites.
Different Types of Reflective Film
- PE Metallized Film
Light‑weight, easy‑to‑cut on‑site. Popular for regular residential floor‑heating projects, offers good moisture‑proof performance. - PET Metallized Film
Higher tensile strength and better temperature‑resistance. More stable under long‑term cyclic heating compared to standard PE‑based options. - BOPP + PET Metallized Composite Film
Dual‑layer laminated structure, improved stiffness and flatness, less likely to curl after installation. - CPP Metallized Film
Soft‑texture composite material, good flexibility, fits uneven ground surfaces during laying. - PET + PE Metallized Composite Film
Combines the strength of PET and the moisture‑barrier property of PE, balanced performance for medium‑to‑long‑term usage scenarios. - Aluminum‑Foil Laminated Composite Film
Uses real aluminum‑foil as the reflective layer. Delivers stable reflectivity, suitable for high‑standard commercial heating projects.
Key Advantages
- Redirect part of radiant heat upward, reducing heat loss downwards
- Moisture‑resistant layer to isolate moisture rising from the sub‑floor
- Provides a flat bedding layer to hold heating pipes in position
- Multiple material grades available to match different‑budget projects
- Custom roll width, length and thickness can be produced on request
Practical Installation Recommendations
1. Place the reflective‑side facing the heating pipes.
2. Leave proper overlap between adjacent film rolls to reduce gaps.
3. Avoid sharp‑edge scratches and piercing during construction.
4. Compatible with water circulation underfloor heating and electric heating cable layouts.
