Each person in the construction of a house, cottage or other buildings always wants to save. There are cases when this saving is justified and does not entail serious consequences. But there are those things that you can’t save on.
Arguments in favor of the control crate
If you want to style metal tile without the use of a control crate, you will have problems in the future. Your coating may deteriorate over time and become unusable. We will give you arguments in favor of the control crate:
- Metal roofing is considered ventilated coating. In practice, this means that there must be a ventilated space between the finishing material and the waterproofing.
- According to the recommendations of specialists, the smallest gap between them should be 5-7 cm. To provide such a space, the control crate, which is made of timber, is called for.
- Using a control crate, avoid moisture accumulation which can focus in places where the waterproofing and stepwise crate are in contact. With it, drops of water freely flow from the top of the roof to its eaves. At the same time, the surface of the bars of the counter-lattice remains dry, which means that it does not require additional processing of the tree with an antiseptic.
- Availability counter lattices allows you to install waterproofing in a quality manner. Thanks to her are absent wrinkles on waterproofing film, which is impossible to achieve in the absence of a crate.
- In addition to the above described using a control crate, a partial ramp alignment. This may be the case when the rafter system was mounted in violation of building production standards or differences occurred in the rafter system itself.
- The presence of a control crate allows craftsmen who are engaged in the installation of metal, move freely on rafterswithout harming the existing waterproofing. Why is it important? Because waterproofing film - these are materials that, as a rule, do not withstand tensile loads. These include, first of all, roofing material and glassine.
The need for waterproofing
Now let's talk about the need to do waterproofing.
If we talk about the air temperature under the roofing and outside the roof, then it is significantly different. The waterproofing film is installed in order to prevent the accumulation of condensate on the inside of the roof during operation of the metal tile.
If there is no waterproofing, then moisture in the form of condensate will penetrate into the insulation and lead to a loss in the performance of the roof several times.
It is possible that water can even penetrate into the interior of a house.
This suggests the conclusion that the backing and waterproofing are important for the long service of your roof.
