Feedthrough for metal roofing: installation rules

In the installation of building structures and the laying of finishing coatings, most attention is paid to the main material - in this case, the flooring. Working with a roof means placing roofing materials in accordance with the requirements for the operation of the house. However, even if the metal roofs are properly installed, the roof will not perform its protective functions if the master has not taken care of the tightness. Invasion of the roof structure, caused by the need to implement technological exits, inevitably violates the integrity of the coating. Optimize and in some cases make controlled the formed gap will help the passage element for the metal, which retains the main function of the technical hole, but also minimizes the impact of negative weather factors.

What is the gateway?

In fact, this is a small hood that is mounted on a pre-prepared base in the roof. That is, first a hole is made, and then it is closed with a suitable chimney or a ventilation complement. It is important to note that the ventilation ducts for metal roofing can be made of different materials, the choice of which should be handled responsibly. For example, plastic elements are very practical and convenient to install. Also they are not afraid of atmospheric influences, corrosion and wind. But they do not go in comparison with stainless steel in terms of strength.

As a rule, the construction of the passage elements is formed by three parts - the base of the hood, the tube and the head for exhaust air, smoke or various impurities. From the point of view of installation, the passage element for metal roofing is the simplest component of the roofing hardware. The technique of installation is simple, but much depends on the skill and attentiveness of the roofer, since any deviation in the location of the element will reduce its performance.

Preparing for installation

The site in which it is planned to install a pass-through system is prepared not only by cleaning the surfaces, but also due to the modernization of the structure. In advance, it is necessary to provide a system for supplying air masses to the wire of the element. Further, an aperture is created, and only then can the site be completely prepared for installation. According to the characteristics of the passage element for metal tiles in general corresponds to modern roofing coatings, therefore it will not be difficult to reduce two types of material. But to correctly fit the sealing parts, you still need to perform a cleansing of the surface of the installation site and degrease.

Making a hole in the roof

Form the hole should be at the highest point of the corrugation and at a sufficient distance from the junction of the two layers of metal. Then, using the template sheet, which is usually supplied with the pass fittings, it is necessary to outline the contours of the cut. Usually, metal roofing under these conditions is opened with a jigsaw. In order for the duct element of the chimney to be installed exactly, care should be taken to ensure that the clips and seal are precisely positioned. Rubber lining is integrated into the formed niche, covering the opened edges. Depending on the structure of the roofing cake, it is sometimes necessary to trim the padded insulators. In this case, it is necessary to prepare and sealing putty, which fill the contours of the connection of the passage device and the insulation material.

Installation of a passage element on a metal tile

The introduction is carried out directly into the hole made so that in the future it remains possible to screw the complete hardware into the clips installed in the niche with the seal. Manufacturers at the factory make the mounting holes along the whole circumference of the passage element, therefore during the fastening it is possible to do only with a screwdriver or a screwdriver. The main thing is that the passage element for the metal tile should stand tight and without gaps. It is not necessary to economize on sealants, since the reliability of the roofing in general will depend on the density of the location and the absence of through sections.

Manufacturers

High-quality roofing fittings are manufactured by Vilpe. In its lineup the components of different configurations, sizes and stylistic designs are presented. Technologists regularly improve and plastic materials, from which the base of products is executed. True, this product is not expensive - about 5-6 thousand rubles. As for specific models, the specialists have gained special trust in the Huopa and Vent series. Also, technological advantages are demonstrated by the last line of the manufacturer - Muotokate. It is a flexible and therefore multifunctional passage element Vilpe. Metal tiles in this case gently and gently adhere to the flange without the risk of damage. As an alternative, we should also offer the products of "Technonikol". Although this line demonstrates simpler and even in some families even budgetary solutions, their cost such passages quite pay back by quality.

Conclusion

Functional and reliable roofing is the guarantee of successful operation of the house. The main emphasis in the work on the design and external provision of the roof is still made on the creation of a durable coating. The same metal, coupled with waterproofing materials should meet the operating conditions in a particular region. However, do not underestimate the task of auxiliary accessories. For small country houses and cottages the entrance element for metal tile "Technonikol", stably providing the basic functions of ventilation and chimney system, is quite suitable. Objects, in the construction and finishing of which expensive material and complex truss structures are used, it is desirable to provide a pass-through system of the Vilpe brand or products of the same level. If desired, in the future, such a device can be supplemented with other optional solutions that increase the operational capabilities of the roof.
