3 Layer Heat Insulated UPVC Roofing Sheet

Special Feature: Heat & Sound Insulation

The 3 layer heat insulated UPVC roofing sheet is manufactured based on 3 layer co-extrusion technology by one-time processing. It is an ideal building material for construction projects with heat insulation requirement. The following is a list of the distinct features of each layer of material.

Surface layer
Weather resistant resin is selected as the top layer material to block the solar ultraviolet radiation and reduce the coefficient of heat conductivity. It provides our UPVC roofing material with great durability and chemical corrosion resistance.

Middle layer
The middle layer is a special foam structure with heat and sound insulation performances.

Bottom layer
The bottom layer of our heat insulated UPVC roofing sheet adopts modified PVC material to offer optimum strength and rigidity.

Applications of 3 Layer Heat Insulated UPVC Roofing Sheet
Due to the above three kinds of materials, our insulated UPVC sheets become an ideal heat and sound insulating roofing material for use in corrosive or high temperature areas. They also create a sense of space and beauty. They are suitable for use in countries and areas with varied climate conditions, including the Middle East, Africa, Asia, and more.

The 3 layer co-extruded UPVC roofing sheet is often used in places with certain thermal or sound insulating requirements, including balcony, car sheds, and more. It is a popular construction material for flat roof to pitched roof renovation projects, as well as buildings such as chemical factories, warehouses, prefab houses, farmers markets, and more. Additionally, this kind of sheeting material can be utilized as wall panels.

Product Advantages

Superior heat insulation performance

With fabulous heat insulation performance, our UPVC roofing sheet offers heat conductivity coefficient of 0.07W/(m.K), which is only 1/6 that of cement tiles and 1/2200 that of 0.5mm thick color steel tiles.

Good sound insulation performance

By absorbing the sound, this range of UPVC roof panel is soundproof. Its sound insulation effect is 35dB higher than color steel sheets.

Highly corrosion resistant

Due to exceptional corrosion resistance, the product comes without any chemical reactions even when it is immersed in the saline solution, alkali solution, or the acid solution with concentration below 60% for continuously 24 hours. Unlike color steel sheets, this plastic sheeting material won't rust, so it is able to avoid water-leakage problems.

Splendid water resistance

The unique external design, coupled with our patented waterproof fittings, makes sure all the fastening screws won't rust. This is one of the reasons why our heat insulated UPVC roofing sheet has superb water resistance.

  • Special Waterproof Fittings
  • Application Project

Good fire-resistant rating

Our UPVC roofing sheets have undergone fire resistance testing conducted by SGS according to UL 94-2013 standard. The testing proves our products have high flame rating (≥V0), and are ideal nonflammable building material.

Highly efficient installation

The light weight and complete range of installation accessories make our heat insulated UPVC roofing sheet easy for installation. The maximum effective width (for standard products only) up to 1260mm ensures higher installation efficiency and reduced installation cost as well.
