防水透汽膜（呼吸紙）是鋪覆在建筑保溫層之外的一層薄膜，而防水透汽膜技術(shù)正是通過加強(qiáng)建筑氣密性、水密性來達(dá)到節(jié)約能耗、保護(hù)人居環(huán)境、從而提高對建筑的耐久性及舒適性，可更有效的保證維護(hù)結(jié)構(gòu)（外墻及屋面）的干燥，并起到顯著的效果。 

1.加強(qiáng)建筑氣密性、水密性

實(shí)踐證明，無論采用何種立面形式，或屋面鋪設(shè)形式，都無法保證圍護(hù)結(jié)構(gòu)的密閉性。以外墻來說，抹灰的開裂難以避免，掛板的搭接難以嚴(yán)密，而單純的磚石砌塊則更無法做到“不透風(fēng)的墻”。這些問題，在建筑陰陽角，搭接處及門窗周圍更為顯著。通過這些非密閉的孔隙，氣流及水汽即可侵入圍護(hù)結(jié)構(gòu)，從而對建筑的能耗、耐久性及舒適性產(chǎn)生嚴(yán)重影響。

2.建筑能耗 

雨水及隨氣流侵入圍護(hù)結(jié)構(gòu)的水汽將降低保溫層的有效熱阻值，從而導(dǎo)致更多的能耗。當(dāng)然，水汽對不同保溫材料的影響是有所區(qū)別的。侵入的氣流將在建筑圍護(hù)結(jié)構(gòu)內(nèi)部形成對流循環(huán)，也將降低保溫層的有效熱阻值，導(dǎo)致更多的能耗。同樣，氣流對不同保溫材料的影響是有所區(qū)別的。氣流侵入室內(nèi)，人們將不得不采用更為龐大的暖通設(shè)備來彌補(bǔ)熱／能量的損失，從而增加建筑能耗。 

3.建筑耐久性

侵入圍護(hù)結(jié)構(gòu)內(nèi)部的水汽，將導(dǎo)致墻體空穴形成水汽凝結(jié)（所謂冷凝水），加速建筑材料的老化，如鋼材的銹蝕和木材的腐朽，從而對建筑的耐久性產(chǎn)生嚴(yán)重影響。 　

4.建筑舒適性

氣流的侵入，將對對室內(nèi)的熱工舒適性產(chǎn)生不利影響；帶來不同建筑構(gòu)件上沉積的污染物和來自建筑材料或室外的放射物，從而對室內(nèi)空氣質(zhì)量造成影響；進(jìn)入建筑圍護(hù)結(jié)構(gòu)內(nèi)部的水汽，為圍護(hù)結(jié)構(gòu)的水汽凝結(jié)創(chuàng)造了條件，導(dǎo)致霉菌形成，從而對室內(nèi)空氣質(zhì)量及居住者的健康造成影響。可見，加強(qiáng)建筑的氣密性，水密性對建筑節(jié)能、環(huán)保至關(guān)重要。

5.建筑透汽性 

由于室內(nèi)外溫差的存在，建筑圍護(hù)結(jié)構(gòu)內(nèi)部的結(jié)露是難以避免的。但實(shí)際上，只有當(dāng)圍護(hù)結(jié)構(gòu)一直處于潮濕的狀態(tài)時(shí)，才會引發(fā)潮氣問題，導(dǎo)致對建筑能耗、耐久性及舒適性的不利影響。因此，為了避免問題的發(fā)生，保證建筑的透汽性，使其可以通過將水汽擴(kuò)散到室外的形式達(dá)到自然干燥，則顯得尤為重要。

Waterproof vapor permeable membrane (breathing paper) is a layer of film spread outside the building insulation layer, and the waterproof and vapor permeable membrane technology is to save energy consumption and protect the living environment by strengthening the air tightness and water tightness of the building, so as to improve the durability and comfort of the building, and can more effectively ensure the dryness of the maintenance structure (exterior wall and roof), and play a significant effect.

1. Strengthen the air tightness and water tightness of the building

Practice has proved that no matter what kind of fa?ade form or roof laying form is used, the airtightness of the envelope cannot be guaranteed. As far as the exterior wall is concerned, the cracking of the plastering is unavoidable, the lap of the hanging board is difficult to tighten, and the simple masonry block cannot achieve the "impermeable wall". These problems are more pronounced in the yin and yang corners of the building, the lap joints, and the surrounding doors and windows. Through these non-confined pores, airflow and water vapor can penetrate the envelope, which can have a serious impact on the building's energy consumption, durability and comfort.

2. Building energy consumption

Rainwater and water vapour that enters the envelope with the air flow will reduce the effective thermal resistance of the insulation, resulting in more energy consumption. Of course, the effect of water vapor on different insulation materials is different. The intrusive airflow will create convective circulation inside the building envelope and will also reduce the effective thermal resistance of the insulation, resulting in more energy consumption. Similarly, the effect of airflow on different insulation materials is different. When airflow intrudes into the room, people will have to use larger HVAC equipment to compensate for the loss of heat/energy, thus increasing the energy consumption of the building.

3. Building durability

Water vapour that invades the interior of the envelope will lead to the formation of water vapor condensation (so-called condensation) in the wall cavities, which will accelerate the aging of building materials, such as rust of steel and decay of wood, which will have a serious impact on the durability of the building. 　

4. Architectural comfort

The intrusion of air currents will adversely affect the thermal comfort of the room, bring pollutants deposited on different building components and radiation from building materials or outdoors, which will affect the indoor air quality, and the water vapor entering the building envelope will create conditions for the condensation of water vapor in the envelope, leading to the formation of mold, which will affect the indoor air quality and the health of the occupants. It can be seen that strengthening the air tightness and water tightness of the building are very important for building energy conservation and environmental protection.

5. Building permeability

  　Due to the temperature difference between indoor and outdoor, condensation inside the building envelope is unavoidable. In practice, however, it is only when the envelope is constantly damp that moisture problems can occur, adversely affecting the building's energy consumption, durability and comfort. Therefore, in order to avoid problems, it is particularly important to ensure that the building is vapor permeable, so that it can achieve natural drying by diffusing water vapor to the outdoors.

當(dāng)水蒸氣透過結(jié)構(gòu)層進(jìn)入保溫層后,會使保溫層含水率增加,導(dǎo)熱系數(shù)也隨著增大,致使保溫層保溫能力下降。又由于保溫層上面的防水層是不透氣的,因此保溫層中的水分不能擴(kuò)散掉,此時(shí)保溫層會逐漸隨著水分的增加而失去保溫作用,導(dǎo)致柔性防水鼓包、龜裂,使防水層失去防水能力。解決這一問題關(guān)鍵是在保溫層下、找平層上設(shè)置一道隔氣層,把室內(nèi)傳來的水蒸氣阻隔在下面。

A vapor barrier, also called a vapor retarder, is a layer in the building envelope that prevents water vapor from entering the wall cavity. There are three different classes of vapor barriers. The class of vapor required depends on the climate zone and cladding type. In many cases, no vapor retarder is required. 

Moisture control is critical in today’s airtight and well-insulated homes. In the past, vapor barriers were often installed on the inside of the building envelope to keep moisture from condensing inside the wall cavity during winter, which could encourage mold growth. But this can potentially keep walls from drying out if moisture condenses inside the wall during summer months. Building science research has refined when vapor vapors should be used, depending on both the climate and the type of cladding used. 

Vapor barriers are classified by their vapor permeance, or perm rating, which is a measure of the rate of moisture diffusion through the material. Class I vapor barriers have a vapor permeance of 0.1 perm or less. Class II vapor barriers have a vapor permeance of between 0.1 and 1.0 perm. Class III vapor retarders have a vapor permeance of 1.0 perm or more. 

No vapor barrier is required for mild or hot climates. Building code does require them in colder climates (zones 5 through 8), but in many cases a Class III vapor barrier like latex paint or a Class II barrier like Kraft-faced insulation is adequate. 

反射隔熱膜又稱鋁箔隔熱卷材、阻隔膜、隔熱膜、隔熱箔、拔熱膜、反射膜等。由鋁箔貼面+聚乙烯薄膜+纖維編織物+金屬涂膜通過熱熔膠層壓而成，鋁箔卷材具有隔熱保溫、防水、防潮等功能。鋁箔隔熱卷 材的日照吸收率（太陽輻射吸收系數(shù)）極低（0.07）具有卓越的隔熱保溫性能，可以反射掉93%以上的熱量，被廣泛應(yīng)用于建筑屋面與外墻隔熱保溫。

Reflective heat insulation film is also known as aluminum foil heat insulation coil, barrier film, heat insulation film,Thermal insulation foils, heat drawing films, reflective films, etc. It is made of aluminum foil veneer + polyethylene film + fiber braid + metal coating film laminated by hot melt adhesive, aluminum foilThe membrane has the functions of heat insulation, waterproof, moisture-proof and so on. The sunlight absorption rate (solar radiation absorption coefficient) of aluminum foil insulation coil is extremely low (0.07), has excellent thermal insulation performance, can reflect more than 93% of the heat, and is widely used in building roof and exterior wall thermal insulation.
