Abstract
The article covers different application aspects of the products made of polyethylene foam within the scope of insulation systems of framed and frameless constructions used in the quality of storage premises, logistic objects, agricultural storage facilities and livestock facilities as well as framed residential buildings. Agricultural storage facilities, livestock facilities, covered parking areas for agricultural machinery and some types of storage premises represent the agricultural construction facilities which require the established protection systems against excessive heat losses as well as monitoring of the state of the internal environment - its temperature and humidity. These structures are built based on one of three schemes: frameless type, framed type with a rigid coating and framed type with a tent coating. The insulation of buildings constructed before 2010 is predominantly characterized by usage of mineral wool plates (with a protective facade covering) or sandwich panels. The main problem of suchlike coverings is the impossibility of creating an insulating coating without joints, seams or gapless junctions to the base. Mineral wool plates, in case of destruction of the waterproof coating, contact with water and firstly lose their thermal and physical properties, and then – come to the destruction themselves. Sandwich panels are more resistant to weather impacts, but create a coating with huge quantity of cold bridges and paths of convective air transfer through gaps or openings.
Highlights
The situation began to change when the development of insulation systems of agricultural facilities using polyethylene foam has started
The material could be recommended as a thermal insulation of objects, operated at temperatures above -60°C
Insulation system of vegetable storehouses should contribute to the implementation of the following tasks: providing maximum thermal resistance of the insulated metal structure, minimization of the cold bridges and external air infiltration paths, reduction of mechanical loads on the metal frame, contribution to long-term exploitation of the construction simultaneously maintaining all basic thermal physical properties
Summary
The situation began to change when the development of insulation systems of agricultural facilities using polyethylene foam has started. For decades products made of polyethylene foam have been used within the scope of pipeline insulation, in the quality of substrate layer for laminate, as sealing gaskets, etc. The thermal, vapour and air insulating coating is created with the help of mechanical fixation of polyethylene foam rolls on the load-bearing structure with subsequent connection of the separate sheets into the locking joint and welding them with the hot air by means of a heat gun (Fig. 1). The insulating material is mounted on the inside of the galvanized metal profiled sheet; in framed systems, the insulating coating is installed on the outside of the load-bearing frame [4,5,6]
