Arrangement of ventilation passing through the roof should not be confused with conventional exhaust air ducts. Of course, traditional home ventilation may well have an exit through the roof, but in this case, it is the under-roof space ventilation system that is being considered, which, however, can also be interfaced with base shafts. The fact is that ventilation outlets can perform different tasks, one of which is the removal of condensate. And concrete, and metal, and wooden roof structures are destroyed by moisture. Therefore, the integration of a device that provides relatively free access of air from the outside is simply necessary for them.
Ventilation features for metal roofing
Roofing from a metal tile is not the most problematic solution in terms of ventilation. The device of such roofs is different in that they do not create the effect of a completely sealed vacuum and in some cases can even do without special air exchange channels. But this is not always the case, and in most cases, in order to ensure the durability of the sub-roof structure, the craftsmen decide oncreating an exit. However, in terms of arrangement, such coatings are less convenient. As a rule, ventilation outlets for metal tiles are multi-component systems that are integrated in stages and form an air duct. Installation problems may be due to the fact that the roofer has to intrude into the roof structure, and in the case of tile decks, this operation requires special skill.
Output performance
There are several aspects to assessing the quality of the ventilation duct passing through the roof. First of all, it should be a design that is resistant to wind, mechanical and atmospheric influences. Even at the time of purchase, ventilation outlets are checked for tightness, tightness of connections and flexibility in terms of functionality. The latter property is determined, for example, by the possibility of integrating the system into roof structures with different angles.
The aesthetic merits of the product deserve special attention. Since the exit will inevitably stand out against the background of the general stylistic composition of the roofing, it is important to take into account the textured performance of the material and its texture. That is, the ventilation outlets are selected according to the color scheme and material. Of course, the choice of material is determined more by technical requirements, but if this choice is not fundamental, then metal should be preferred.
Varieties of exits
There are two implementation conceptsroof ventilation, under which manufacturers of such systems orient their products. These are continuous and point outputs. The first option represents models that are installed entirely along the length of the ridge. Their feature is inconspicuousness, since the design does not protrude on the surface of the coating. If you choose a texture that matches the metal tile, then even with a close inspection, the functional element will be invisible. And yet, point ventilation outlets for metal tiles are more common, which are fixed in the ridge zone with certain indents from each other. However, sometimes one element is enough. The advantages of such systems include the function of aeration and forced injection of flows.
Reviews of Wirplast models
The Polish company Wirplast sells models of ventilation outlets in a huge range. Products differ in different characteristics - from decorative solutions to technical and structural design. Users also note the versatility of this product. The manufacturer offers modifications to provide a direct channel for ventilation of the under-roof space, a model for the antenna passage, organizing the exit of the siphon riser, etc. Also, many point to the quality of the fittings. Even in budget versions, the Wirplast roof outlet is equipped with high-quality accessories that allow for reliable installation and adjusting the function of the channel to specific needs.
Reviews of Vilpe models
The Finnish brand Vilpe is a reference manufacturer of ventilation systems. The owners of such equipment for the roof emphasize its durability, versatility, original design solutions and ease of installation. By the way, the developers calculate different models for the needs of specific roofs, focusing on the slope and coating material. For example, the Vilpe ventilation outlet in the Muotokate series is ideal for metal decking. According to consumers, the material of this collection is durable and protected from climatic influences. Also, thanks to a special coating, the output components are not covered with small scratches and traces of other minor damage.
Reviews on TechnoNIKOL models
This is a domestic manufacturer that covers a wide range of different finishing and insulation materials. It should be noted right away that these products are inferior in quality and manufacturability to the developments of Wirplast and Vilpe Vent. Experienced users rather recommend TechnoNIKOL ventilation outlets as an inexpensive budget solution for simple tasks. For example, such devices make it easy to implement a single point exit for the roof of a small house. In addition, the owners of ventilation systems of this family note good design performance.
How is the roof vent installed?
First you need to form a hole in the metal tile. Usually suppliers of this material provide special subassemblieswith rounded elements - it is desirable to use them in the installation of the output. Further, an o-ring is integrated into the resulting nest, which will further ensure the reliability of fixing the components. Lastly, install ventilation outlets with related fittings. Mechanical fixation is carried out by means of screws, and in addition, it will not be superfluous to apply silicone-based sealant to the joint area - this will be waterproofing.
Conclusion
The efficiency and performance of an exhaust system is largely determined by the quality of its design. You should not initially consider this element of the infrastructure of the house as a separate functional accessory. Often, ventilation outlets to the roof are mounted as a universal channel that combines several tasks. For example, through one shaft, it is possible to implement both kitchen exhaust ventilation and air exchange in the under-roof space itself. Another thing is that such a scheme will require a more detailed calculation, as well as the use of additional fittings to connect different segments of the channel. But in practice, such solutions show themselves more efficiently than several separate outputs that require more costs. Moreover, investments will apply to both the purchase of material and the maintenance of the installed structure.
