Waterproof and breathable membranes enhance the airtightness and watertightness of buildings while their unique vapor permeability allows for rapid expulsion of moisture within the structure. This preserves the thermal performance of the protective structures, truly achieving the goal of reducing building energy consumption. Additionally, it prevents the growth of mold in the structure, protects property value, and addresses issues of moisture and human health. It is a new, environmentally friendly energy-saving material.

Applying a waterproof and breathable membrane to the roof can act as an insulator.

Insulation combined with structural layers. Both structural and thermal components. There are generally two methods: one is to install insulation within the grooved board, which can reduce construction procedures and enhance industrialization, but at a higher cost; the other is to integrate a waterproof and breathable membrane with the structural layer, such as a gas-filled concrete roof panel. This component can bear loads and provide insulation, simplifying construction and lowering costs, but its load-bearing capacity is smaller and durability is poorer, suitable only for roofs with lower standards and no pedestrian access.

Positioned thermal insulation. The insulation layer is placed below the waterproofing layer and above the structural layer, which is a common practice. Most thermal insulation materials without self-waterproofing properties can be positioned in this location on the roof.

Inverted Insulation System. The insulation layer is placed above the waterproofing layer, with the construction layers being the insulation, waterproofing, and structural layers. The insulation material must have low water absorption, resist decay when submerged for extended periods, high compressive strength, a wide safe working temperature range, and a low thermal conductivity coefficient.
