Alanni - Tame the wind
Long life, strength and safety, functionality, maximum light, lower costs of heating and air conditioning, low maintenance - these are some of the requirements to be met by the modern windows and doors. Offering high stability and durability, aluminum material and PVC-U (Polyvinyl Chloride) find increasing use in new buildings and renovation of old buildings.
The windows of PVC-U are mainly used for glazing of buildings due to its good insulation properties. Aluminium is a suitable material for making windows (with a large area of glazing), entrance doors and internal partitions, curtain walls. Such profiles are often used for office buildings and retail outlets.
The windows are a matter of personality and because everyone is looking at them and their idea of comfort and style. And we in turn seek optimal solutions to make this possible.
