Wood floor moisture-proof pad is what material

Answer:

Open-type foam moisture-proof pad: generally made of expanded polyurethanes (polyurethane), which there are many subtle air chamber can allow the outside air into the formation of isolation layer. Its benefits are comfortable enough, light weight, and the price is not expensive; internal air chamber limits the flow of air, you can achieve a good isolation effect. The disadvantage is that it will absorb water, once encountered water can not be used; bulky, not easy to compress, the use of inconvenient, and the isolation effect is not closed foam waterproof pad to the good. Closed foam moisture-proof pad: the inside contains a lot of closed subtle air foam foam pad, the general market is divided into foam moisture pad, tin foil drained moisture-proof pad, folding moisture pad benefits is cheap, high durability , Even if the ice claws pedal, the same can be used; value for money isolation effect, because the air inside the closed air almost no flow, will not absorb water. The disadvantage is a certain weight, the thickness of the mat than the open-type moisture-proof pad is thin, so to choose a more heavy, sleep more comfortable. Automatic inflatable moisture-proof pad: the inside is open foam moisture-proof pad, the outer layer coupled with the organization of tight, good waterproof nylon cloth, at the same time in the corner with a inflatable valve to facilitate the flow of air is the advantage of comfort with open Foam waterproof tiles as well, but the isolation is better than the "open" outer layer of waterproof nylon cloth limit the moisture inside the moisture barrier, through the inflatable valve can adjust the size of moisture-proof pad size, and very solid, at any time Can maintain a certain thickness. The disadvantage is expensive; easy to be punctured or torn, although the repair technology is not difficult; weight heavier.
