Purchase and price of wholesale flat roof bitumen
It can be difficult to know where to start when it comes to the best way to choose the appropriate bitumen roofing membrane, regardless of whether you are an architect, a roofing applicator, or anybody else involved in the process.

When comparing the various features and qualities of the various bitumen flat roof products, it might be difficult to determine which one is the best option for your regional market or for each individual project.
The Built-up Roof (BUR) system's asphalt-based, more distantly related relative, the Modified Bitumen (MB) roofing system, was developed specifically for buildings with low-slope or "flat" roof systems.
The first roofing membranes made of engineered modified bitumen were developed in Europe in the middle of the 1960s.
Since about 1975, these membranes have been used successfully in the United States of America, Canada, and many other nations across the world.
Modified bitumen roofing systems are built to survive hard conditions caused by prolonged contact with extreme environmental factors.
Because it has five different layers of defense, this is one of the most reliable systems for flat roofing that is used in the market today.
The bitumen flat roof membrane is a single-ply rolling roof that is impregnated with a mineral-based wear surface. It is constructed in a manner that is analogous to the ice-and-water shield.
Heating the adhesive during the torch-down process, in which the material is unrolled, is required. The more recent peel-and-stick technologies are more user-friendly and secure.
As it is difficult to choose, we have prepared a series of questions and answers to direct you through the process of selecting the appropriate.
bituminous product in accordance with the requirements of your project, which will be followed by a discussion of the various properties of bitumen that should be taken into consideration.
- Where exactly will this product find its use?
Temperature and weather conditions in the area help determine the type of bituminous compound that should be used: oxidized bitumen, elastomeric (SBS).
plastomeric (APP), elastoplastomeric (a mixture of SBS and APP), or elastoplastomeric (mix of SBS and APP) (which is not polymer-modified).
- What is the Purpose of Using This
The top surface of the membrane is decided upon taking into account both the location and the method of application.
In most cases, flat surfaces (talc, sand, or PE foil) are recommended for use in ballast systems or as a base sheet in multi-layer systems in order to guarantee the correct bonding of the layers that are applied on top.
Covered membranes, such as granulated surfaces, both safeguard the substance and make it possible to employ the membrane itself as an exposed layer.

- What are the Prerequisites and Requirements
In order to pick the reinforcement, which is the component that is responsible for the material's mechanical qualities, the minimum expected performance criteria need to be specified.
Here are several examples:
Polyester: A material with improved tensile and elongation propertiesGlass fiber: Increased dimensional stability due to the use of glass fiber
Aluminum: This material is useful as it acts as a vapor barrier (most indicated to vapor control layers)
Your system build-up is also defined by the sort of reinforcement that is used, which refers to whether the membrane is put in a single layer or a double layer.
For two-layer systems, glass fiber reinforced membranes are almost universally indicated as the material of choice.
For polyester reinforcements weighing more than about 140 gr/m2, a single-layer membrane is the only option that is recommended.
- What is the average number of years someone lives
A general indicator of the quality of the bitumen membrane is whether or not it retains its flexibility at low temperatures.
Because of the quantity and quality of the polymers, the endurance of the membrane increases in proportion to how much less flexible it is when exposed to cold temperatures.
It is recommended to conduct additional aging experiments in order to assess the thermo-oxidizing profile.
After the needs of the project have been specified, it is time to investigate the other characteristics of the bituminous membrane.
in order to construct the system that is suitable and necessary. The following is a list of some of the most important qualities that bituminous membranes possess.

Flexibility in the ColdThe flexibility of the membrane when it is cold, also known as the flexibility of the membrane when the temperature is low, is a general indicator of the quality of the membrane.
because it is related to the environmental conditions and also to the expected lifespan of the membrane. The idea behind it is straightforward: the higher the number, the less cold flexibility the material has, and the better its performance.
ReinforcementThe reinforcement is what gives the bituminous membrane its mechanical properties, such as strength (tensile force), elongation, and resistance to ripping and shear.
Other mechanical features include elongation. These numbers need to be in line with the characteristics of the building in order to guarantee that the membrane will.
be resistant to movement and loads that are applied to it. Glass fiber, glass fleece, aluminum, non-woven polyester, polyethylene foil, and some other combinations are among the most prevalent types of reinforcement materials.
The same idea that was implemented with cold flexibility is employed here, in which a number is used to distinguish between the.
various kinds of cold flexibility. The higher this number is, the better the membrane's mechanical qualities are, and the more adaptable and versatile it is for a variety of functions and applications.
