Wood is the oldest and most widely used raw material for manufacture of windows. This is not just because the product is completely natural, environmentally friendly and pleasant to the touch, but above all else it is characterised by excellent sound and thermal insulation, as well as resistance to external factors.
The high quality of wood windows is a result of properly selected and dried wood, as well as its density.
There are many species of wood that can be used in the manufacture of wood windows. One may traditionally assume that pine wood is the most popular in Poland because of its wide availability.
There are also other species, such as Oak, Fir, Larch and Spruce. Although used for windows much less frequently, be it because of the price or limited availability, they are still of interest to our clients. Other wood species used in the manufacture of wood windows are exotic species, such as Meranti, Cedr, Teak, Iroko, Doussie, Merbau, Acajou, Durian, Mukulungu, not to mention true Mahogany.
We have in offer products made of pine, larch, oak, meranti and Majau wood. Of course this list is not closed and if a customer wishes to have windows made from another species, we can accommodate such a request.
Spruce wood is light, soft, has medium strength parameters and is low on resin. It has worse parameters than pine, but is cheaper. The wood taken from trees aged 80 – 120 years offers the best properties. It is characterised by a density of about 340 – 470 kg/m3. Two types of spruce are distinguished – lowland and mountain. Windows should be manufactured only from the mountain variety, as the lowland one offers little resistance to moisture and biological corrosion. Due to the average parameters of spruce wood it is usually coated with body colour. Available at no extra charge in all versions of windows – 68 mm, 78 mm, 90 mm.
Due to its price and availability this is the most common coniferous species used in the manufacture of windows and doors. Considered one of the longest living plant species on Earth. The wood taken from trees aged 80 – 120 years offers the best properties. It is characterised by a density of approximately 450 – 550 kg/m3, which ensures good properties in terms of both compressive and tensile strength.
Pine wood is relatively long lasting and durable, yet flexible and easy to process and offers perfect thermal insulation. A high resin content makes it resistant to damage resulting from moisture, but at extremely high temperatures it can pass through the paint coating. The colour of the wood is bright and it can be effectively covered with opaque and stain paints. Available at no extra charge in all versions of windows – 68 mm, 78 mm, 90 mm.
This is the best and most durable wood from among coniferous species, with a very nice and regular grain. The wood taken from trees aged 100 – 120 years offers the best properties. It is ideal for manufacturing windows and doors. Larch wood is characterised by its very high resistance to humidity – it does not suffer from biological corrosion and does not deform under its influence.
The hardness of larch wood increases over time – so called petrification. Its density is in excess of 550 kg/m3. A high resin content means that at extremely high temperatures it can pass through the paint coating. However, the larch is a relatively rare species and therefore quite expensive.
It is the best building material from among native broad-leaved trees, better than pine and even larch. Oak wood is counted among fine tree species which is a symbol of dignity, strength and exceptional durability.
Only heartwood of a tree trunk should be used for the manufacture of windows, as the sapwood part is easily destroyed by insects. The wood taken from trees aged approximately 180 years offers the best properties. It is a hard wood species, heavy, resistant to water and abrasion. Its density in the range 650 – 750 kg/m3 gives it the best strength properties of all wood species native to Poland.
The interesting grain and colour of oak windows have for centuries enjoyed unfaltering renown around the world. Its excellent performance and attractive appearance make it very expensive.
Exotic wood from broad-leaved trees from Indonesia, Malaysia and the Philippines. The most commonly used by manufacturers from among the exotic species. It comes in several varieties, of which the white and red varieties are the most popular. The density of meranti is strongly dependant on the species and reaches values ranging from 300 kg/m3 to 800 kg/m3. It is worthwhile to find out what is the density of the wood, as it affects its parameters.
Our company offers species with a density greater than 450 kg/m3. In general, this type of wood offers high resistance to moisture and, therefore, low probability of cracking. It is durable and robust. It demonstrates very good thermal and acoustic insulation characteristics. It has a highly characteristic wood pattern, which looks very impressive when coated with transparent paint. An analysis of basic physical and mechanical parameters indicates that meranti wood shows greater resistance to weather phenomena than pine. Interestingly oak is not far behind.
Meranti offers better technical parameters than pine in such areas as shrinkage and swelling by 39%, static bending resistance by 41% and the hardness by nearly 40%. The resistance of exotic wood species to shrinkage and swelling stems from their anatomy. These are heartwood species with a wood that is characterised by low water permeability. Its red-brown colour lends the product a certain elegance and a warm ambience to the interior.
Windows from meranti wood will be appreciated by all those looking for exotic beauty combined with high quality and durability of the products. This wood is available at no extra charge in all versions of windows – 68 mm, 78 mm, 90 mm.
The wood for the connoisseur. The jewel in our manufacturing crown since 2008. A hard broad-leaved tree wood coming mainly from the island of Borneo. Its minimum density varies between 580 kg/m3 and 850 kg/m3. It is used mainly for the manufacture of select windows and doors in furniture making, boat building, construction.
It is a wood that offers very good resistance to water and other atmospheric factors, highly valued because of the beautiful wood grain and its physical properties. You can find more information in the article “Giants from Asia”. This wood is available at no extra charge in all versions of windows – 68 mm, 78 mm, 90 mm.
