In the roofing building materials market, resin tiles have gradually become a popular choice for self-built houses, factory remodeling and slope conversion projects due to its lightweight, beautiful and convenient installation advantages. However, a core problem has always plagued the majority of consumers:How long is the general life of resin tilesWhy is it that some people are still in good shape after 20 or 30 years? Why is it that some people are still good as new after 20 or 30 years, while others crack and leak after 3 or 5 years?
How long is the average life of a resin tile?
To answer this question, we cannot simply give a number. This article will combine national testing standards and industry data to provide readers with an objective and authoritative reference basis.
First, the general life of the resin tile how long - high-quality products 20-35 years
According to the testing data of the National Testing Center for Chemical Building Materials and industry technical guidelines.How long is the general life of resin tilesDepends on the material grade of the product. Using imported ASA raw materials, ASA layer thickness of not less than 0.15mm of high-quality resin tiles, under normal use conditions can ensure that the color difference value ΔE ≤ 5 within 10 years, the actual service life of up to 25-35 years.. According to the relevant technical guidelines of China Building Waterproof Association, the thickness of ASA layer on the surface of high-quality ASA resin tiles should be no less than 0.15mm, which is the core parameter to ensure its weathering life (usually promised to be up to 20-30 years)。
High-quality resin tile in the actual installation and use, sun exposure does not fade, low temperature is not brittle, corrosion resistance, impact resistance performance is excellent, the normal service life of up to 20-30 years.。
In sharp contrast, poor-quality products (ASA layer <0.1mm or ABS impersonation) installed after one or two years that is white and color fading, three or five years on the surface cracking, waterproof function failure。How long is the general life of resin tilesThe answer is: a good tile lasts half a lifetime, a bad tile is useless in three years.
II. Key factors affecting the life of resin tiles
1. Surfacing materials: the world of difference between ASA and ABS
The weathering performance of resin tile, 90% depends on the surface layer material. High-quality resin tiles use ASA engineering resin as the top layer - ASA molecules do not contain unsaturated double bonds, so they are able to resist degradation caused by ultraviolet rays, and remain stable in complex environments such as high temperatures, humidity, and acidic rain.ASA's weather resistance is about 10 times higher than that of ABS, and after 9-15 months of exposure to sunlight, there is almost no decrease in impact strength and elongation, and the color remains almost unchanged.-。
The weather resistance of ABS material is poor, easy to fade, aging, usually in less than a year there will be obvious quality problems, can not guarantee the long-term use of the resultsThe life expectancy of resin tiles is far from the standard that they should be used. Unscrupulous businessmen to reduce the cost of ABS instead of ASA, its life is far less than the use of resin tile should be standard.
2. Purity of raw materials: the fundamental difference between new and recycled materials
High-quality resin tiles are made of high-purity ASA resin and virgin PVC to ensure the weather resistance and toughness of the tiles.The products produced with recycled materials are brittle, easy to break, and contain a lot of impurities. The products produced with recycled materials are brittle, easy to break, contain a lot of impurities, poor color, impure and easy to fade!-The recycled material tile is dark in color. When choosing and selecting, it is recommended that the following methods of screening: high-quality tile cross-section levels, the surface has a layer of 0.15-0.2mm thick ASA weathering layer, the bottom layer of white or gray substrate; recycled material tile color dull, impurities on the surface, and the strength of the poor easy to break!。
3. Installation quality: good tiles also need professional construction
Even the best material, not standardized installation will affect the service life. Resin tiles are suitable for sloping roofs with a slope of 20-80 degrees.The installation should be done with special self-tapping bolts. Installation requires the use of special self-tapping bolts, first pad the bolt gasket and then moderately tightened, and then cover the waterproof cap. The purlin spacing should be in accordance with the product requirements, and the fixing parts need to be made of stainless steel to prevent rusting leading to fixing failure. Standardized construction is an important guarantee to extend the service life of resin tile.
Third, how to buy high life resin tile
When choosing one, it is recommended to focus on the following four segments:
A look at the test report. Standard resin tile in the purchase of the National Chemical Building Materials Testing Center should show the relevant test reportsThe test report of artificial aging is the authoritative basis for measuring the weathering resistance. Artificial aging test report is the authoritative basis for measuring weather resistance, artificial aging 10000 hours is equivalent to the actual use of more than 20 years. High-quality products can even pass 12,000 hours of artificial aging test, ΔE color difference value is as low as 2.23-3.86, indicating that the color stability is very good under strong light, not easy to fade。
Second look at the thickness of the ASA layer. The thickness of ASA layer on the surface of high-quality ASA resin tile should be not less than 0.15mm.The weather resistance of some high-quality products is up to 0.16mm ASA. Part of the high-quality products surface layer ASA up to 0.16mm, by the National Chemical Materials Testing Center 12000 hours anti-aging experiment proved that the weather resistance performance is equivalent to the actual use of more than 25 years!. Selection can be observed when the section of the tile, the surface color layer is clearly visible, the bottom layer of white or gray substrate。
Third, look at the source of raw materials. Be alert to the use of ABS or recycled materials instead of ASA substandard products, the weather resistance is far from the sameThe color and luster of the new material is even and full, and the knocking sound is dull and thick. Brand-new material products are even and full of color and lustre, and the knocking sound is dull and thick; recycled material tiles are dull in color and lustre, have impurities, and the knocking sound is clear and crisp.。
Four look at fire and impact resistance. High-quality resin tile fire rating up to B1, with self-extinguishing, self-extinguishing within a few seconds after leaving the fire; in the support spacing of 660mm under the conditions of bearing 150kg without breakage.. Products that do not meet this standard not only have a short lifespan, but are also a fire safety hazard.

IV. Proper use and routine maintenance
Even if you buy a high-quality resin tile, reasonable use and regular maintenance is equally important. Once or twice a year, clean up the leaves and sand on the tile surface, using a soft brush or a low-pressure water gun; before the rainy season, check whether the screws are loose and whether the seams are cracked, and then repair them in time; make sure that the slope of the roof conforms to the construction specifications, and avoid the accumulation of water to accelerate the aging of the material. Correct maintenance can make the service life of resin tile extend another 5-8 years.
summarize
How long is the general life of resin tilesThere is no standard answer to this question, but there is a clear law: the material determines the bottom line, and the construction affects the upper limit. Choose ASA layer thickness ≥ 0.15mm, through the artificial aging test of the regular products, please professional team standardized construction, do a good job of routine maintenance, resin tiles with two or three decades is completely feasible; on the contrary, greedy for low price to buy low-quality products, installed a few years on the need to replace, but cause greater economic losses.
In the purchase of roofing materials, please be sure to recognize the official test report, choose the regular manufacturers, so that each piece of resin tile for your roof to provide long-lasting peace of mind guard.
