The extensive conservatory renovation near the Dachstein involved modernising a wood-aluminium conservatory of around 15 m². The existing old-style conservatory had several rotten areas in the timber structure and let in water when it rained, which had already compromised its load-bearing capacity and made prompt action necessary. In addition, inadequate insulation, despite existing shading, led to overheating in summer with temperatures above 30 degrees and to insufficient warmth in winter. As part of the conservatory renovation, the existing glass roof was replaced with an insulated solid roof, which significantly improved energy efficiency and reduced the heat problem for good. Thanks to the improved insulation values, warmth stays inside in winter and summer heat is effectively kept out. The side surfaces of the conservatory were rebuilt with larger glass elements to create a stronger connection to nature, allow more transparency and increase living comfort through an open, bright feel. Two balcony doors were also upgraded to modern triple glazing to noticeably reduce noise from the nearby main road and significantly improve sound insulation. The combination of high-quality materials, modern glazing technology and a natural look results in a sustainable and attractive conservatory solution that convinces both functionally and visually. This conservatory renovation shows how existing conservatories in Austria can be made energy-efficient, quiet and comfortable to live in for the long term through professional modernisation.
