What factors affect the effectiveness of insulation of external walls?

The system external wall insulation insulate a is a very good way to building from the outside. High-quality materials and a qualified repair team are the keys to success and proper installation process. What factors affect the effectiveness of such warming?

Each type of building insulation requires an appropriate assembly method and high-quality materials that are resistant to moisture. Without these factors, the operation of the insulation system may prove to be insufficient or impossible at all, and as a result of improper installation, it may develop moisture and mold, which is later very difficult to remove. A professional and qualified repair team that specializes in external wall insulation is a guarantee of solid performance, and thus – excellent durability of all insulation. An additional, equally important issue is the selection of high-quality materials that show insulating properties and are resistant to moisture and heavy rainfall. The ideal solution will be a combination of both aspects, and at the same time regularly refreshing the insulation of the external walls and careful observation of cracks or small defects formed over time, as well as immediate reaction and renovation.

What materials should I use to insulate exterior walls?

The key to proper operation of the insulation system is to match the right materials. Regardless of the type of insulation, it is worth focusing on products and materials of the highest quality, because the effectiveness and durability of the entire insulation system depends on them. If we choose materials that are not resistant to moisture, we will unwittingly contribute to the formation of mold and the multiplication of fungi and bacteria, while the insulation will not fulfill its functions. The heat obtained through electric heating will then be absorbed by inadequately insulated walls, which will increase our monthly bills for electricity consumption. Therefore, using high-performance render, which show strong properties resistant to harmful weather conditions, and appropriate insulation boards, we gain a guarantee of functionality and perfect protection of walls against moisture and cooling.

Can we install external wall insulation ourselves?

Installation of external wall insulation may seem like a fairly simple operation, however, specialists do not recommend installing such insulation on their own. The main reason is the constantly changing building law, which the average person is not able to update on a regular basis. Qualified employees of professional companies dealing with insulation of external walls regularly increase the scope of their knowledge and gain experience that makes the performance of the service efficient and effective. Knowledge of issues related to construction law and knowledge about the necessary permits to carry out renovation are absolutely priority, therefore it is worth entrusting the installation to specialists who are willing to consult their activities with the client and make every effort to meet the client’s expectations.

Do weather conditions affect the functionality of external wall insulation?

High-quality materials, which are usually used when installing external wall insulation, show high resistance to harmful weather conditions. So let’s put on appropriate insulation boards and waterproof varnishes or high-performance render, protecting the building against moisture and micro-damages. Installation of external wall insulation should take place in favorable weather conditions, so that the materials do not get wet or damaged. If heavy rainfall impairs renovation work, secure the property and discontinue work, then continue operations as conditions improve. The whole assembly usually takes up to several weeks, so you should decide on installation in spring or summer, when the weather is more predictable and reliable.
