In theory, the more layers of UPVC roofing sheet, the better. So in actual use, has anyone practiced how the number of layers of UPVC roofing sheet affects the thermal insulation effect?
-1. The advantages of multi-layer boards: more layers, good sound insulation, good heat insulation, and stronger support than two layers.
-2. Disadvantages of multi-layer boards: For rain awnings with arched arcs, the more layers of boards, the greater the impact on the service life.
-3. Cost comparison: The cost of multi-layer board is compared with two-layer board. Because of the use of more materials, the price is also much higher. If the materials used are not increased in proportion to the multi-layer board, the thickness of the multi-layer board will not keep up, but will become thinner. It also affects the quality of use.
The following is an analysis of UPVC roofing sheet for your reference and communication:
-1. The key to the service life of PVC corrugated vinyl roofing is the top layer, not the number of layers. Therefore, the multi-layer board does not bring much benefit of the service life. Only the third item above is mentioned in case of rain with an arched arc. Shed instead affects life span.
-2. The purpose of your choice of multilayer board is nothing more than heat insulation and strong support. Do you think the PVC corrugated vinyl roofing installed in the past, how many users mentioned insufficient heat insulation or insufficient strength, now you increase the cost to choose whether the multi-layer board is cost-effective.
-3. If the same amount of material is used, you can only make two layers for the multi-layer board. Do you say whether the board wall is thicker? The thicker board wall is really beneficial to the service life, so it is recommended to choose the multi-layer board instead of adding it. Thick plate.
-4. So under what circumstances is it better to choose a multilayer board? The space is too small, the height is too short, the support frame is too thin, or the material used for the screen is really critical for the heat and sound insulation support.
For the selection of UPVC roofing sheet materials, you must not follow blindly. The increase in the number of layers of PVC corrugated vinyl roofing cannot effectively achieve a better PVC corrugated vinyl roofing heat insulation effect. In general, UPVC roofing sheet planning should consider every detail as much as possible, together with the surrounding environment, and think about the later stage. Only by the decoration function can we plan a more reasonable and perfect space.
