Basic Wood Characteristics

It is not enough to note that wood is a natural and ecological material. As far as architectural structural solutions are concerned, wood is one of the most suitable materials. First of all, this is related with its firmness, resistance, good sound and heat insulation and electrostatic qualities, ability to maintain a natural moisture balance indoors and air circulation. Also, this is determined by its specific texture, odour and broad processing opportunities (in terms of shape, size and colour). Finally, wood is a renewable natural resource, and old wooden windows can be processed and used and used for the second time. Both technical and design characteristics are appreciated by architects and designers as well as our clients who are already enjoying individual wooden window solutions.

Wood is suitable for any interior/exterior; one has to merely select the most suitable type of wood and methods of processing. The aim of Doleta UAB is to prevent you from unsound decisions.

However, the production of wooden windows is very advanced today wooden windows can have various shapes, colours, texture and even odour. Some unique characteristics also depend on wood from which windows are produced.
