This is a great choice for those looking for a good price and durability. Windows are really warm with their thermal conductivity coefficient reaching more than 1.00 W / m2K.
„Doleta Alu-90“ wooden windows are made of three layers of various types of wood (from simple pine to exotic eucalyptus). They can be of different shapes: rectangular, trapezoidal, arched, round, etc. On the outside, such windows are covered with aluminum profiles with a gap left from the wood part to allow the wood to breathe.
