Noise reduction and condensation effect reduction metal roofing sheet

Description

Noise reduction and condensation effect reduction metal roofing sheet can give you better working and living environment. Traditionally we use the colour coated galvanise, galvalume and  colour Coated Galvalume as metal roofing sheet. But as it can not reduce noise and absorb condensation water, it takes many trouble for our living and working.

The roof of a building is an important part of the building. Defended and insulated against external noise. Zhongtuo metal roofing and cladding sheets technology means that 4 or 5 tenths of metal can be improved by 6 mm of high-density sound insulation, adhering perfectly to the sheet (aluminium, pre-painted steel, etc.).

We can have a sound insulated metal roof that decreases the impact of rain, hailstorm, it will not vibrate thus there is no diapason effect. This gives a padded emission quite similar to brick roofs. In fact, to absorb noise, a roofing packet consisting of components with different physical characteristics.

In order to solve those problem, Zhongtuo New Material developed a new type material for reaching the effect of Noise reduction and condensation effect reductio. Here are some basic information for your reference:

Significant noise coming from direct impact (noises transmitted by air), which can be easily transmitted to underlying premises and thus increase discomfort.

The size of a hailstone is generally 0.5 to 2 cm in diameter and the effects it can have when impacting a roof depends on the material used. Brick roofs, for example, are hard but unable to absorb the impact, becoming fragile to later crack and break resulting in leakage. On the other hand, metal roofs are malleable but do not break and, absorb the impact, are dented but do not lose their weatherproof function.

We also call it as Metal roof sound absorber:

Relatively speaking, the noise caused by raindrops on the metal roof

The sound is much louder than the sound directly falling on the ground, and it will

Spread throughout the building and quickly spread indoors, because

This will directly affect the activities of people indoors.

Mute King noise reduction felt as an insulating layer can effectively reduce raindrops

noise.

Now comes to the condensation effect reduction:

Zhongtuo New Material is an economical and environmentally friendly anti-condensation solution. It can replace insulation panels and dehumidifiers to protect roof systems and buildings from condensation.

Why Zhongtuo Noise reduction and condensation effect reduction metal roofing sheets have such function?

1. On the surface of the raw material, it is same like other PPGI, so no big different.
2. Just base on the bottom we add another layer of cross-linked Polyethylene Foamed Sheet.

Now let us check what is cross-linked Polyethylene Foamed Sheet, and how it is functional?

Cross-Linked Polyethylene Foam (XLPE) Features:

Chemically cross-linked polyethylene foam is an extremely fine-celled foam, ideal for projects and applications that require thicker foam. With a smooth, pleasant feel combined with superior physical and chemical properties, cross-linked polyethylene foam is the solution for an array of applications that demand thicker sections of closed-cell foam. With its closed-cell density, XLPE works well commercially as thermal insulation, construction expansion joints, and industrial gaskets. It is also used as packaging and in flotation equipment, with its low moisture permeability and high buoyancy. XLPE can also be carved and sanded for one-of-a-kind DIY projects.

Details:

• Resilient
• Excellent buoyancy
• Good thermal insulator
• Excellent strength and shock absorption
• Low water absorption
• Impervious to mildew, mold, rot, and bacteria
• Excellent chemical resistance
• Nontoxic and contains no CFCs, HCFCs, or hydrocarbon blowing agents
• Similar to Minicel in USA, Alveolit in Europe, and Softlon in Japan and Australia

How we make those two layers together?

We mark these two layers by hot pressing machine, and after making them to two layer coil, you can use it to make any shape and size by metal roofing sheet rolling forming machine.
