One of the key factories ensuring the highest windows quality is wood and how wood is processed. Our windows are produced using laminated wood beams in the Nordic pine and oak. Other type of wood such as Mahogany Sapele and Siberian larch can be both: solid and glued beams. All wood which we are using has FSC certification. It means that wood are from forest that are 100% replanted.
Nordic Pine: nordic pine is from 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 natural strength.
Oak : the quality of oak are 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 attack, also it is durable even in contact with moisture beyond all common belief. Oak is characterized as durable, long lasting with a bright and strong wood texture.
Sapele: 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 the attractive aroma resistant to insects.
Sibirian larch: sibirian larch timber is naturally beautiful – so no finishing 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 colours from golden brown to yellow sssand orange in the heartwood.
