Arrangement of ventilation through the roof should not be confused with conventional exhaust air outlets. Of course, traditional home ventilation may well have an exit through the roof, but in this case it is the ventilation system of the under-roof space that is considered, which, however, can also be coupled with the 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 rafter structures are destroyed by moisture. Therefore, the integration of a device that provides relatively free access of air from outside is simply necessary for them.
Features of ventilation under a metal roof
A roof made of metal is not the most problematic solution in terms of ventilation. The device of such roofs is characterized in that they do not create the effect of a completely tight vacuum and in some cases even can do without special air exchange channels. But this does not always happen, and in most cases, in order to ensure the durability of the under-roof structure, the masters decide to create an exit. However, in terms of arrangement, such coatings are less convenient. As a rule, ventilation exits for metal tiles are multicomponent systems that integrate in stages and form an air duct. Installation problems may be due to the fact that the roofer must invade the coating structure, and in the case of tiled floorings, 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 resistant to wind, mechanical and atmospheric influences. Even with the purchase, the ventilation outlets are checked for leaks, tightness of connections and flexibility in terms of functionality. The latter property is determined, for example, by the ability to integrate the system into roof structures with different angles.
Aesthetic advantages of the product deserve special attention. Since the output will inevitably stand out against the background of the general stylistic composition of the roofing, it is important to consider the texture of the material and its texture. That is, the ventilation outputs are selected according to the color scheme and material. Of course, the choice of material is determined rather by technical requirements, but if this choice is not fundamental, then it is worth giving preference to metal.
Varieties of Outputs
There are two concepts for the implementation of roof ventilation, under which manufacturers of such systems orient their products. These are continuous and point outputs. The first option is models that are installed entirely along the length of the ridge. Their feature is inconspicuous, because the structure does not protrude on the surface of the coating. If you select a texture that matches the metal tile, then even with a close inspection, the functional element will be invisible. And yet, more common are point ventilation exits for metal tiles, 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.
Wirplast Model Reviews
The Polish company Wirplast sells models of ventilation outlets in a huge assortment. Products differ in different characteristics - from decorative solutions to technical design. Users note the versatility of this product. The manufacturer offers modifications to provide a direct channel for ventilating the under-roof space, models for the antenna passage, arranging the outlet of the siphon riser, etc. Also, many indicate the quality of the hardware. Even in low-cost versions, the Wirplast brand roof vent is equipped with high-quality accessories that allow for reliable installation and adjusting the channel function for specific needs.
Reviews about Vilpe models
Finnish brand Vilpe is a reference manufacturer of ventilation systems. Owners of such equipment for the roof emphasize its durability, versatility, original design solutions and ease of installation. By the way, the developers are calculating different models for the needs of specific roofs, focusing on the slope and coating material. For example, the ventilation outlet Vilpe in the Muotokate series is optimally suited for metal tile flooring. According to consumers, the material in this collection is durable and weatherproof. Also, thanks to the special coating, the output components are not covered by minor scratches and traces of other minor damage.
Reviews about Technonikol models
This is a domestic manufacturer that covers a wide range of different materials for decoration and insulation. It should be noted right away that these products are inferior in quality and manufacturability to the development of Wirplast and Vilpe Vent. Experienced users would 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 designs.
How is the ventilation outlet mounted to the roof?
To begin with, you should form a hole in the metal tile. Typically, suppliers of this material provide special nodal components with rounded elements - it is advisable to use them in the installation of the output. Further, a sealing ring is integrated into the resulting socket, which will further ensure the reliability of the fixation of the components. Lastly, ventilation exits with associated accessories are installed. 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 section - this will be waterproofing.
Conclusion
The efficiency and performance of the air exhaust system is largely determined by the quality of its design. You should not initially consider this element of the home infrastructure as a separate functional accessory. Often, ventilation exits to the roof are mounted as a universal channel that combines several tasks. For example, through one shaft it is possible to realize exhaust kitchen 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 accessories to connect different channel segments. But in practice, such decisions are more effective than several separate outputs that require more costs. Moreover, investments will relate to the acquisition of material, and to the maintenance of the installed structure.
