Insulation roofing sheet
Insulation roofing sheet
This is a new environmentally-friendly Heat Insulation material, which is soft, light and easy to install. It is made from aluminum foil and polyethylene by special machinery. It has no odor and toxicity. It not only overcomes the discomfort and environmental damage brought by glass fiber and epispastic materials, but can also resist ultraviolet radiation that can penetrate through sheet iron, concrete, wood and other common heat insulation materials. This new heat insulation material not only has good insulation, heat reflection & insulation and anti-radiation functions, but also has good moisture-barrier, heat preservation and energy-saving functions in housing construction (roof).
Function
Can be installed on roof, resists over 80% external heat from buildings, protects wall, resist thermal shock and sudden cold, etc.
Characteristics
- No odor and toxicity, environmentally-friendly
- Light, soft, dust free, fire, retardant, easy to install
- Heat reflection, heat insulation, sound insulation, anti- radiation, anti- vibration, and shielding
- Moisture, barrier, sun-proof, waterproof, good sealing property, heat preservation, energy saving
- Summer: moisture barrier, sun-proof, heat insulation, saving energy consumed by cool air conditioning
- Winter: heat preservation, central heating saving, and remarkable
Structure of Pre-Painted Steel Sheets
Benefits / Key Feathers:
- Replaces fiber bats and building in most applications and helps achieve MINIMUM 5 to 7 Degree cooler inside.
- To resist moisture and reduce condensation and it prevents the canfid of temperature level differences.
- Thermal insulated Metal Sheet prevents rein impact and other sound at 50 decibel
- The stable heat performance even in high humidity environments.
- Enhanced corrosion protection
- It is no toxic and environment friendly.
- Reduce the electricity consumption in cold storage and many more storage area.
- It gives aesthetic look to quality industrial commercial buildings.
- Very low maintenance and excellent durability.
