Question:

Will the tent waterproof index be valid against rain at 800---1500?

Will the tent waterproof index be valid against rain at 800---1500?

Answer:

In addition, one of the key factors to inspect the waterproof property of tents is the adhesive treatment of the joints at the tent joints. Only when the glue is prepared can the rainwater be kept free from the cracks in the stitches.Many domestic tent factories, PU coating technology is unstable, and very uneven, rainproof performance can not be guaranteed. So choose a tent, recommended to choose high quality manufacturers, many well-known brand does not mean high quality, but some outdoor professionals from the development of local brands, professionals constantly through this kind of product quality supervision, the pursuit of perfect performance is the ideal choice of the tour pal. Like "limit outdoor" brand, because the platform is rooted in outdoor, Alice and other professionals, the price than some international big name low, but the quality is the same standard.
Tent mat is directly paved on the ground, easy to touch the ground moisture, rain is also easy to soak in the water, so the seat of the waterproof index requirements than the external account to be higher.If the three quarter (spring, summer, autumn) account is not used in harsh environments, waterproof PU in the 2000MM-3000MM will be enough. Like extreme outdoor climbers, double double deck camping tents, waterproof exterior PU2500-3000MM, in mid and heavy rain environment can be used.Four seasons account, you need to use in alpine, snow and other harsh environment, waterproof coefficient is relatively high, to be in 3000MM - 5000MM or so. Like this extreme outdoor pioneer double double deck camping tent, is the typical alpine snow tent.
The PU800 coating indicates that the coating is impervious to 800MM's static water column. Waterproof 300MM is usually used for beach curtains, sun curtains, or cotton curtains for dry and rainy days. Waterproof 800MM-1200MM is used in a conventional tent for simple camping, and it prevents small to moderate rain. Waterproof 1500MM-3000MM for comparison of mid-range tents, you can prevent moderate to heavy rain. Waterproof 3000MM above is generally a professional tent, to take high temperature / cold resistant, cold and other techniques, and basically can be used in a variety of environments.
The thickness of the PU coating and the coating technique determine the water repellency of the fabric. The coating thickness is expressed in mm, indicating the static column height of the coating under laboratory conditions.
