Another benefit: wood has excellent insulation values for heat and sound by nature.

Your questions – our answers Aren’t windows and doors made of plastic or metal not much better than wooden elements?


Wood is a naturally grown high-tech material and its complex physical properties are unrivalled. Wood is naturally solid and has excellent insulation values for heat and sound. Due to its natural oils, it has an antibacterial effect, is breathable and thus ensures a healthy living climate and good moisture balance. Plastic and metal elements cannot compete with this! It is evident from the listed buildings that wooden windows and doors can last for centuries. Plastics become porous over the years, bleach out and are no longer repairable. It is different with wood: it can always be reworked and restored if necessary.

Plastic elements are certainly cheaper to buy, while wooden windows and doors have a very high value and should be seen as a long-term investment. Each piece of wood is unique and we can work, shape and combine it with additives in an infinite number of ways. This flexibility and versatility make wood an unrivalled material. And moreover: Wood as a natural and sustainable material is unbeatable when thinking of the environment.
