Engineering communications in the house require appropriate infrastructure support. In particular, the chimney and ventilation system provide for the organization of the exit through the roof. Previously, such an opportunity was provided with the help of special openings, which, after installation, were appropriately sealed with sealing means. Nowadays, manufacturers of engineering equipment offer more reliable solutions, including roofing penetration, which is arranged directly in the roof structure.
What tasks does roofing solve?
To determine the purpose of such additions to the roofing pie, you should turn to the functions of the roof itself. It should protect the house from precipitation and other external influences, while maintaining optimal heat, noise and waterproofing. The presence of holes and cracks in the roof is not allowed, therefore, communications passing through the roof must be carefully sealed in places of contact with the finishing material and the power structure. In turn, roofing penetration initially creates a minimum of free space, which is not used for engineering purposes. At the same time, it contributes to the effective removal of smoke and air, protecting the roof materials from heat exposure. Ventilation systems, by the way, often lead to the formation of condensate in places where air flows. Special nodes for such channels impede the processes of drip formation, removing moisture to the outside.
Varieties of penetration
There are several classifications of roof penetrations. First of all, it is worth focusing on a specific purpose. Manufacturers produce special models for organizing the passage of antennas, pipes, ventilation ducts and chimneys. The belonging of a node to a certain group determines both the structural design and the material of manufacture. So, not all types of penetrations can be adjacent to a stone chimney. Also, plastic devices cannot be combined with some types of metal pipes. The nodes differ in shape. The most widespread are round and square sections, but in some cases only corner roofing, which has its drawbacks, but also advantages, can help. Structures with such a cross section, for example, are advisable to use in tight conditions or when laying non-standard coatings.
Driving Management Methods
All penetrations allow air to escape through the roof. Thus, a channel is formed, which can also facilitate the passage of cold air into the attic. In the simplest models, this nuance is not taken into account in any way and the nodes in a constant mode provide uncontrolled air passage. A more advanced roofing penetration also provides the ability to control the duct using a valve. In low-cost entry-level systems, manual control of the gate valves is provided, but there are many automated models that can be controlled from a distance. Moreover, devices with intelligent control systems that control valves based on current weather conditions are becoming more popular.
Universal driving
Knots of this type are, in essence, insulating tubes that organically fit into the opening due to the silicone shell. True, in this configuration additional protection should be provided around the passage. The main task performed by such penetrations is the mechanical protection of the pipeline or chimney from damage. In addition to the external silicone coating, the assembly has a metal layer and thermal insulation. These are optimal roofing penetrations for round pipes of ventilation systems, since they can adapt to any bend. What is more important, thanks to the stepped structure, such devices allow you to direct the channel in one direction or another as needed. Orientation of the pipe is possible in traditional penetrations, but a change in direction in such cases requires a lot of effort.
Installation of penetration
The installation technique largely depends on the specific option of sinking. But in most cases, installation involves the implementation of three stages. First of all, the base is arranged, on which the knot will stand. It can be a concrete or metal glass, which will support the construction as a foundation. The second stage involves the direct conduct of the communication pipe through the node, as well as the execution of crimping actions. The installation of roofing penetration by mechanical fixation on the roof surface is nearing completion. To do this, use self-tapping screws, mounting brackets, screws and nails. The specific mounting method depends on the roof finishing material.
Accessories for roofing
Additional elements that increase the reliability, functionality and durability of the roof unit include crimp accessories, sealing and heat-insulating materials. For example, using a coating of silicone or polymer elastic fabrics, you can provide an isolated area around the installation site. Thanks to this reinforcement, roofing will last longer and will not allow moisture and debris to pass through the opening. In some cases, it is advisable to use elements of mechanical reinforcement. Such solutions are used for insurance in case of windy weather.
How to choose the right penetration?
Initially, you should focus on dimensional parameters. The larger the ventilation opening or chimney, the thicker the walls of the assembly should be. In addition, the insulating qualities of the penetration are taken into account. For example, if plastic can provide tightness, then in terms of thermal insulation it will be effective only if it is further strengthened. On the other hand, metal roofing for chimneys must necessarily have a corrosion-resistant coating. Actually, due to the risk of developing negative rusting processes, experts do not recommend using such models at all.
Conclusion
Consideration of issues of additional equipment of the roof should be approached even at the stage of designing the roof. In the design itself, it is possible to provide specifications for the passage of the communication channel and for the installation of the node. For example, wide roofing penetration for ventilation may require additional fastening in the area of rafters. But this possibility is not always allowed in finished structures. Also, do not save and refuse the modern proposals of manufacturers of penetrations. The same automated models will save you from a lot of trouble during the operation of the installation. For example, the latest versions of such units allow you to programmatically control the valve control - so that it will automatically select operating modes depending on the season and temperature amplitudes. However, simple installations without valves should not be excluded if it is planned to operate in a warm region.
