Why the roof needs to lay roofing nonwoven, these advantages look at.

First, waterproof auxiliary function

Enhance the life of waterproof layer

Roof non-woven fabric can be used as an auxiliary material for waterproof layer. Before laying the waterproof layer (such as asphalt waterproof coil, etc.), the roof non-woven fabric is first laid, which can provide a smooth and stable base for the waterproof layer. For example, when the roof of some old buildings is repaired, the base may not be very smooth, and non-woven fabrics can fill some small gaps and unevenness, preventing the waterproof layer from stress concentration due to the unevenness of the base, resulting in rupture or damage.

When the waterproof layer is affected by external factors (such as temperature changes, building settlement, etc.) and there are small cracks, the roof non-woven fabric can play a role in buffering and preventing the further expansion of cracks. Because the non-woven fabric has a certain tensile strength and elasticity, it can withstand a certain degree of deformation, thereby extending the service life of the waterproof layer.

Prevent water penetration

Although the roofing nonwoven fabric itself is not the main waterproof material, it has certain impermeability. Its fiber structure is relatively tight, which can prevent water from permeating through the roof base capillary. This impermeability is particularly important in areas with more rain. When the rain falls on the roof, the non-woven fabric can prevent the rain from penetrating directly through the gaps in the tiles or other roofing materials into the interior of the roof structure, thereby reducing the risk of roof leakage.

Second, thermal insulation function

Thermal insulation effect

The roof non-woven fabric can reflect part of the solar radiant heat. Its color is usually lighter, and the light-colored material can reflect more sunlight, reducing the heat absorbed by the roof. In the summer, the solar radiation is strong, and a lot of heat is passed into the room through the roof. With the roof non-woven fabric, you can effectively reduce the temperature of the roof, and then reduce the indoor heat absorption, play the role of insulation, reduce the frequency of use of indoor air conditioning, save energy.

There is a large amount of air gap in the fiber structure inside the roof non-woven fabric. Air is a good insulating medium, and these air gaps prevent the conduction of heat. Just like the use of thermal insulation materials in the wall insulation of a building, the roof non-woven fabric forms a thermal barrier between the roof and the interior space through this air insulation, making the indoor temperature more comfortable.

Insulation performance

In the cold season, the roof non-woven fabric can reduce the indoor heat through the roof to the outside world. It can keep the indoor heat inside the building and play a role in insulation. Especially for some buildings without central heating systems or in the case of a sudden drop in temperature at night, the roof non-woven fabric can effectively prevent the rapid loss of indoor heat and improve the thermal insulation performance of the building.

Third, enhance the roof structure stability

Prevent roofing material from shifting

Roof non-woven fabric can play a role in fixing and bonding roofing materials. When laying roofing materials such as tiles and slabs, non-woven fabrics can increase the friction and bonding force between these materials and the base. For example, in strong wind weather, the roof non-woven fabric can prevent the tile from being blown or displaced by the wind, ensuring the integrity of the roof structure. It acts like an invisible "safety net" that holds the roofing material tightly to the roof.

For some new roofing materials, such as lightweight solar panels or artificial turf roofs, roof non-woven fabrics can provide good grass-roots support for them. These materials themselves are light in weight, but they may move during long-term use because of factors such as wind, rain or personnel walking, and non-woven fabrics can effectively prevent this from happening.
