For sloped roofs, there are certain requirements for the construction of extruded boards. As long as we see such roof construction at the construction site, extruded boards are mostly supporting roles, because this is a roof using asphalt waterproof tiles and extruded boards are used. Here, the role of extruded boards is to insulate and protect tiles and waterproof layers from damage. Of course, the natural hydrophobicity of extruded boards can also play a certain waterproof role. Specifically, it depends on whether the joint treatment between the edges of extruded boards is in place.
Asphalt waterproof tile sloped roof construction is usually divided into six major steps: waterproofing, laying extruded boards, laying asphalt tiles, arranging tile battens, laying surface tiles. Of course, there are some subdivided processes between them, such as cleaning the base layer, driving expansion screws for fixation, etc., which are indispensable links in construction. And these links can also determine the quality of the project. Detailed construction processes are usually explained on construction design drawings. Of course, if there is really none, you can negotiate with the owner and supervisor to determine the relevant construction process and flow.
For sloped roof construction, what is actually valued more is the waterproofing link, because this link will directly affect the subsequent decoration and use of the house. Therefore, whether using asphalt tiles or other waterproof materials, achieving no water leakage is the fundamental quality.
The extruded boards usually used for sloped roofs are green high-density, with a thickness of 5CM. The flame retardant requirements are adjusted according to different construction requirements. Some use B1 grade and B2 grade, selected according to different construction environments.
There are many types of related construction processes for extruded boards, but they all need to be applied in different scenarios combined with different environments. Our company can also provide related construction processes for reference.
