Rainbow House is an umbrella brand from Hemei Town, Changhua County, Taiwan, which was once one of the most important exporters of umbrellas in the world. However, the OEM Rongjing of Taiwan's umbrella industry has declined, and so is Rainbow House, which now sells all products for sale in Taiwan (China) and made in China (mainland). In fact, Rainbow House has a higher reputation in Chinese mainland, and its extremely high sun protection and shading power coincide with the consumer demand of mainland consumers who pay equal attention to sun protection and shading.
 
The sunshade products of Rainbow House are all made of Taiwan Fumao umbrella cloth, with a cloth density of 240T, which is the top level in the industry. The umbrella cloth is treated with vinyl technology, and the number of gluing times is as high as 5 times, which has a fairly strong anti-ultraviolet performance, and can easily achieve UPF 50, and the long-wave ultraviolet transmittance ratio T (UVA) is less than 0.2%, which far exceeds the requirements of national standards and international mainstream standards for anti-ultraviolet umbrellas.
 
Compared with the uncoated anti-UV treatment used in Europe, America and Japan, the silver glue and colored glue laminating process popular in Taiwan and Chinese mainland is less costly, but the anti-ultraviolet effect is also remarkable, even better than the former. However, the glossy effect of the adhesive layer treatment makes the texture of the umbrella cloth slightly inferior, and it is easy to oxidize and fall off or wrinkle and sticky, which also has a certain burden on the environment, so it is basically abandoned in developed countries. Generally speaking, the number of times the color glue (black rubber) is processed determines the level of the UV shielding index, the more times the better, and the umbrella labeled as four times (layer) of color glue is commercially available, which has very high UV resistance and shading performance. The products of Rainbow House are glued with up to 5 layers, which are naturally outstanding in ultraviolet protection and shading efficiency, and the bottom of the cloth can achieve almost zero light transmission, and the effective cooling under the umbrella is 3-5 degrees Celsius.
 
The umbrella cloth of the rainbow house is dense and thick, but the weight is not significantly higher than the parasol of the same level on the market, which should be attributed to the umbrella bone and the middle rod used in it, which are basically a combination of lightweight materials such as glass fiber, resin, aluminum alloy, etc., and the umbrella bone is riveted with hollow aluminum nails, which effectively reduces the overall weight, while taking into account a certain firmness, and the umbrella frame is stable and does not shake. Most of the parasols in the rainbow house take a fresh and lovely route, with a lively composition style and a refreshing and bright color, which is relatively suitable for female consumers. In mainland China, Rainbow House authorizes a number of Taobao C stores to sell its products, but some authorized agents have older styles and slightly inferior colors.
 
At present, Chinese mainland consumers can buy parasols for Rainbow House in legal agent stores on domestic e-commerce platforms, and the price of most styles is around 100 yuan, and there is no official direct sales channel for the time being. It is worth noting that due to the large number of lightweight materials used in the umbrella skeleton of the rainbow house, its wind resistance is not eye-catching, but the merchant promises a lifetime warranty for the umbrella bone, and the after-sales conditions are relaxed, and the overall performance is still high.
