The impact of insulation layer on waterproof the flat roof generally needs to do insulation layer, which makes many people don't know whether to do waterproof layer or insulation layer first. In fact, the location of insulation layer will affect the waterproof quality to a great extent.

如果先做保溫再做防水，那就叫正置式屋面；如果先做防水再做保溫，就叫倒置式屋面。

If you do insulation first and then waterproof, it is called positive roof; If you do waterproof first and then thermal insulation, it is called inverted roof.

倒置式屋面相較于正置式屋面，防水層不會出現熱脹冷縮現象，延長了防水層的使用壽命，同時，保溫層對防水層能提供一個物理性保護，防止其受到外力破壞，能達到更好的防水保溫效果。

Compared with the positive roof, the waterproof layer of the inverted roof will not expand and contract, which prolongs the service life of the waterproof layer. At the same time, the thermal insulation layer can provide a physical protection for the waterproof layer, prevent it from being damaged by external forces, and achieve better waterproof and thermal insulation effect.

不過倒置式屋面對保溫材料的要求很高，所以倒置式屋面的成本更高。

However, inverted roof has high requirements for thermal insulation materials, so the cost of inverted roof is higher.
