Contabbed elements: concept, application and varieties
Each roof has weaknesses. You need to try to take care of them as best as possible. For this there are additional elements. These are elements without which the installation of metal tiles, corrugated board and siding panels is impossible.
These products are indispensable not only during roofing, but also in construction as a whole. Any architectural solution will complement the additional elements, because their manufacture in different non -standard forms is possible.
As you can correctly notice, then additional elements perform two functions: decoration and protection. The space that they protected becomes inaccessible to moisture and dust, becomes soundproof and acquires large thermal insulation properties. For the full compliance of caps, strips, parapets, castings and another with a common color scheme of the structure, a special polymer coating is applied to the elements.
Some experts wanted to classify in the additional elements, but in practice this is not applied. Very conditional separation does not help solve the usual problems for this type of materials. The most important thing is not how to classify elements, but to use a full set of prefabricated elements. This will prevent cracks and will contribute to the long operation of the building. For metal roofs, the internal and outer corner, a bar for adjustment, tide of the basement, cornice bar, snow retainers and more are often used. Corner strips are used to finish the external and internal angles of the facade. Thanks to the additional elements, the appearance becomes aesthetic, and the corners become sealed.
