"Underhållsfria fönster" : I vilken utsträckning är dagens "underhållsfria" fönster underhållsfria och hur ser man

Sammanfattning: Abstract The aim of this examination paper is to get an overview on the “no-maintenance” windows that exist on the Swedish market, like plastic and aluminium windows. By way of introduction the reader gets knowledge in the background and problemformulate that this subject has. This introduction explains why it has become so popular to change your windows into plastic- and aluminium windows and there is an existing scepticism against PVC and aluminium as construction material for windows. The main part of this report is constructed by segments of interviews where both producers of windows and stakeholders gets to answer questions about their viewing on no-maintenance windows from a material and construction point of view and where the production is headed to in the future. This is followed by an evaluation of a questionnaire on how pleased the house owners that changed their old windows to no-maintenance windows are, followed by an inspection of windows made up from wood and an aluminium clothing, windows made from only aluminium and PVC-based windows. It ends with a theory part about the materials PVC and metal based upon facts included in literature. By reading this report you can draw the conclusion that no window can be entirely nonmaintenance but that the materials PVC and aluminium still are good substitutes for wood to lessen the maintenance.
