| Popis: | The article analyzes different ways of creating an insulating coating within the scope of frameless buildings. Among such constructions, the production halls, raw material and finished-products storages, agricultural storages, livestock housing, garages, covered parking, sports and cultural facilities are to be distinguished. Criteria that the heat-insulating materials should meet in the context of effective and durable insulation coatings are low thermal conductivity, vapor and water permeability, high operational durability and environmental friendliness as well. It is confirmed that products based on polyethylene foam, such as mats and rolls, fully meet the above-mentioned criteria. Furthermore, the possibility of obtaining a seamless joint during the installation process significantly increases the effectiveness of the insulating coating by means of minimizing cold bridges and eliminating leakages when connecting separate insulating elements. Polyethylene foam is an elastic and well stretching material. When fixing polyethylene foam rolls on the metal covering of the frameless construction, they will change their shape together with the metal due to the climatic temperature drops (stretch and constrict). The performed tests have revealed that the longitudinal tensile strength of the products with a metallized coating is 80–92 kPa, without a metallized coating - 80–87 kPa, and 29–32 kPa of the weld seam. The article includes information regarding the results of thermal imaging monitoring of frameless constructions with an insulating coating based on polyethylene foam. It is shown that hot-air welding (with the help of a hot air gun) allows minimizing heat losses both at the joints of the sheets and in the areas adjoining to the base and to the side walls of the buildings. |
