A seamless method of construction of airtight windows is intended to avoid unnecessary heat loss, but this can result in the vital exchange of air through ventilation not always being guaranteed. Inadequate ventilation may create unhygienic living conditions such as a build-up of carbon dioxide, condensation, odours from the building, materials and people, and so on. By focusing on aesthetically pleasing designs, acoustic and energy-saving aspects, ALU+ have developed a range of natural ventilation products for the European market. The range consists of ventilation systems that are fitted to the frame, or glazed-in. The range of products can be supplied pre-assembled, in a range of colours and sizes. Some products can also be supplied in bar length format, to allow easy installation by the end user. Other window ventilation products may be available, all requests are welcome.
