Polymer sand tiles are analogous to natural tiles. But this material can be called brand new. This roofing is superior to analogues in many ways. Let's consider everything in order.
Reviews
The described material is 2 times lighter than natural, but it costs much less. With the help of such a coating it is possible to provide much better qualities of heat and sound insulation, if we compare with metal tile. Consumers especially note the absence of corrosion processes. It is impossible not to pay attention to the strength characteristics.
Polymer sand tiles are also popular among private craftsmen and professional builders because of their resistance to ultraviolet radiation. It can be operated at significant temperature differences, the range varies from -65 to +100 degrees. Owners of private houses who used the described material as covering material note that during the entire period of operation, the coating remains attractive. Manufacturers guarantee that it takes about 100 years to completely decompose a polymer-based film.
Reviews of moisture absorption and thermal conductivity
If you have chosen polymer sand tiles, then you can count on an insignificant coefficient of water absorption. This indicates that this material will cope with the function of protection against moss, fungus, mold, as well as exposure to moisture and acid rain. This material is also widespread on the market for the reason that it has low thermal conductivity. This indicates that a constant temperature regime will be maintained in the space under the roof. Under such a roof it will be warm in the winter and cool on a hot summer day. Therefore, polymer sand tiles are used in the arrangement of terraces and attics.
Soundproofing and impact resistance reviews
Experts advise choosing the described material because of the combination of useful characteristics (such as low thermal conductivity and waterproofness). This becomes a reliable barrier to condensation. Therefore, the roof structure is protected from destruction, which is especially true for wood elements. Owners of private houses try to choose materials that differ in sound absorption qualities before installing the roof. When laying a polymer sand roof, additional sound-absorbing layers will not be needed. The roof will be silent in any weather. You can also count on impact resistance. Companies involved in the transportation of building materials note that polymer sand tiles, reviews about which are often quite positive, do not break during transportation and installation. It complies with the standards and requirements of sanitary, fire and radiation safety.
How and how to fix polymer sand tiles
Installation of polymer sand tiles can be done independently. The manufacturer took care of this, providing the back of the canvas in the upper part with a special protrusion, which is necessary for fixing to the crate. Between themselves, the components are engaged with the help of side locks, which allows you to form a continuous carpet, which is called a roofing. Polymer-sand tile, the photo of which is presented in the article, has technological holes (in the amount of two) in each element.
Work should start from the bottom row. Fixation to the crate system should not be rigidly done - each fixture should have a backlash. Then you will provide the possibility of free movement, which is necessary for strain expansion during temperature exposure. In addition, the roof should, without deformation, absorb the load from wind, snow, and other natural factors.
Features of installation work
Laying polymer sand tiles should be done in such a way that after fixing on the front side there will be no leakage of rust. In order to exclude such a phenomenon, galvanized nails or anodized self-tapping screws should be used as fasteners. Nails are preferable, as they accelerate installation work, and are also able to provide not too rigid fastening. As for the wind or, as it is also called, the pediment tile, as well as the ridge, these elements are strengthened with the help of anodized self-tapping screws. In the process of work, there will certainly be a need for cutting material, for this you can use a hacksaw designed for metal work, or a grinder.
Professionals Recommendations
It is necessary to begin work with the arrangement of the rafter system. It should be remembered that the total weight of the roof will be quite significant, despite the fact that the described covering material has a small mass, because the system will also have a crate system, as well as rafters. For this reason, attention should be paid to the calculation of the cross-section of the beam, taking into account the loads that will be assigned to it. This may include external temporary influences such as snow, wind, etc.
Most often, a square beam, the side of which is 50 millimeters, is used for the crate. During the installation of the crate, steam and waterproofing should be laid. These layers are needed to protect the roof from weathering and to eliminate moisture components. Such insulation will not interfere with air circulation between the elements.
Conclusion
Choosing vapor and waterproofing, you can use a special insulating film, which is also called diffusion. It should be attached to the grill using the brackets of the construction stapler; it may need to be rented. Some home masters refuse to use the mentioned layers, while experts insist that they be present.
