Luoyang Yu Industrial Co., Ltd. to you about polyurethane insulation board: XPS drawback: the higher intensity XPS board itself, resulting in more brittle sheet insulation board, easy to bend, the stress concentrated stress present in the board, easy to damage the sheet cracking; poor ventilation, almost airtight, if the temperature difference on both sides of a large plate, high humidity and condensation is easy; the plate surface is smooth, the interface needs to deal with at the time of construction, and nap. Mao panel not included; XPS plate with plaster board wall insulation mortar bond is not strong, easy to fall off; external tiling off faster and more severe. Advantages of extruded insulation board XPS:: Luoyang Yu Industrial Co., Ltd. to you about performance comparison XPS board insulation board has a dense inner surface and closed cell structure. Its thermal conductivity is much lower than the same thickness of EPS foam cement insulation board, so it has better thermal insulation than the EPS performance. For the same building facades, its thickness can be less than other types of insulation material; the inner layer of closed-cell structure. So it has good moisture resistance, in a humid environment can still maintain good thermal insulation properties; suitable for cold storage and other special requirements for building insulation, can also be used for external walls made of brick or stone buildings ; light texture, easy to use: rock wool insulation board, insulation board Zhuzhou, preferred by large Henan Luoyang Yu Industrial Co., Ltd. Luoyang, Henan Industrial Co., Ltd. (www.lydayushiye.com/) strong, credible, in Luoyang indoor paint industry has accumulated a large number of loyal customers.
