Our windows are produced using laminated wood beams in Nordic pine and oak. Other types of wood such as Mahogany Sapele and Siberian larch can be both: solid and glued beams. All wood that we are using has FSC certification. It means that wood is from forests that are 100% replanted.[/vc_column_text][vc_empty_space][qode_accordion][qode_accordion_tab title=”Wood types”][vc_column_text]
  • Nordic Pine: is from the slow-grown northern forest (Siberia, Karelia). The wood is soft, medium in weight has medium density, and also has excellent fiber and characteristics: tight growth rings, resulting in natural strength.
 
  • Oak: the quality of oak is truly remarkable. Oak wood has a density of about 0.75 g/cm creating great strength and hardness. It is very resistant to insect and fungal attacks, also it is durable even in contact with moisture beyond all common beliefs. Oak is characterized as durable, long-lasting with a bright and strong wood texture.
 
  • Sapele: is hard and very durable hardwood. Solid Sapele is generally stable when dry, making it ideal for use in doors and windows. It is ideal for painted applications due to its fine graining. Sapele also has an attractive aroma resistant to insects.
 
  • Siberian larch: Siberian larch timber is naturally beautiful – so no finishing is required. This tree is one of the best coniferous woods in the forest, with excellent properties: Much lower moisture absorption levels compared with fir. Impregnation unnecessary. High durability and very resistant to rot and fungus. High mechanical resistance and very good pressure resistance. Excellent wear resistance (Class II). High density Aesthetically pleasing to the eye; warm colors from golden brown to yellow and orange in the heartwood.
