Soon we will start production of 82 mm Scandinavian windows with a heat transfer coefficient of 0.8 W / (m².K)

At the end of 2009 the company JSC “P. Varkojis ir Co.” started manufacturing triple-pane windows to ensure the maximum level of heat insulation.

Scandinavian type triple-pane window U=1.1 W /(m²·K)

Due to the increasing number of inquiries for warmer triple-pane windows from Scandinavia, “P. Varkojis ir Ko” at the end of 2009 began the production of a Scandinavian type window with three panes.

The appearance of new windows stays unchanged, but the thermal properties increase by 30%. From the previous manufactured window, the new window differs in sashes and the thickness of glass. The current window is made with 68 mm thick sash. The new window allows a possibility to put a 34 mm thick glazing unit with three panes – two of which are selective. The window jamb is left unchanged – 118 mm thick.

The thermal conductivity of the new window is U = 1.1 which is confirmed by the certificate of conformity.

Wood – The Oldest Natural Building Material

Jūratė and Pranas Varkojai, who produced their first machine loom themselves and founded JSC „P. Varkojis ir Ko“ in 1994 in Kurmaičiai near Kretinga, better than anyone else know the reason why windows, doors and furniture make the house more cozy, and also help people live healthier and be happier.

The Best Windows Are From Wood

Tree is the symbol of nature and also the oldest building material in Lithuania. It radiates warmth and comfort; thus, people who cherish real values usually build houses, install wooden windows and doors. Timber, is able to ‘breathe’, absorb moisture from the environment and give it away when the air becomes too dry; moreover, it creates unique cozy home atmosphere on which one’s well-being depends. “There is no need to look for advantages to compare wood and plastic as they have already been set,” says Mrs J. Varkojiene the production manager in JSC “P. Varkojis ir Ko” who still hears discussions in Lithuania about what is better – wooden or plastic windows.

Windows are the construction of a building that performs most functions. They keep away cold, wind, and sound, let the light and fresh air in. They have the biggest impact on the indoor climate. Since windows have extremely high quality requirements, a new generation of wooden windows was created using advanced technologies – wood processing and drying were changed, windows are made of three layer waterproof laminated lumber

Window profile has also changed: instead of the double window frame with separate glass the single window pane  is used, two sealing gaskets are mounted in a sach. In order to protect windows from the influence of atmosphere a new paint system has been created. Having extensive experience and investing over two million litas last year into new technologies, the inhabitants of Kurmačiai are confident of their production quality.

Thicker Frame Is Better

JSC “P. Varkojis ir Ko” is the oldest wood processing company in Lithuania that for sixteen years has been producing wooden windows, doors, furniture and even 60 models of small garden houses. The company felt the first signals of economic recession when no one even spoke about that; therefore, the company’s executives acted quickly and decisively and in January 2009 started producing new European standard wooden windows with 92 mm thick frame. Their glass pane thickness is 48 mm. The thermal transmittance coefficient of such panes is U = 0.5 W/(m²·K); and the window thermal transmittance coefficient is U = 0.87W / (m·K).

The thickness of the glazing unit is 48 mm, the thermal transmittance coefficient of which is U = 0.5 W / (m² · K). U is one of the most important parameters of the window, which indicates the amout of heat going through the window in 1 m² in 1 hr at the difference of internal and external temperatures of -1ºC. The lower the coefficient, the less energy is needed to heat buildings, the smaller structures of heat loss, less fuel is burned, less emission, cheaper building maintainance and so on.

According to Mrs J. Varkojienė, due to exceptional technical and engineering solutions, 92 mm thick wooden frame holds heat inside very well, is environmentally friendly and durable. In addition, the thick frame windows are only a tenth more expensive than conventional windows with 68 mm thick frame. According to the director, the small difference in price pays off very quickly because after installing the warm windows the heating costs are significantly reduced.

“Our produced windows are so warm that they perfectly fit for the ‘passive house’. These are so call houses diligently built in Scandinavian countries that lose little heat and in such a way minimize costs of heating and hot water,” claims the specialist. Considering the growth of interest from customers in the Nordic countries, at the end of 2009 the company started to produce even tighter windows. Due to purchase of new modern tools that help put a thicker – 34 mm double-glazing unit, “P. Varkojis ir Ko” reached a new record of the coefficient of thermal conductivity – the coefficient of such windows U is 1.1 W / (m²·K). The new product differs from the previous windows only in thickness of sash and glass package but the thermal properties of Scandinavian window are more efficient by 30 per cent.

Wood Is Chosen In Winter

New technologies were introduced by the company just to produce the warm windows. Italian equipment, which is used to process the glued beams to produce all window parts, was installed at the company’s production workshop. By improving technologies, the main production workshops have been equipped with efficient irrigation equipment. It ensures that all rooms are maintained at 10-12 per cent humidity; therefore, the wood does not crack nor curl and the staff enjoyes breathing fresh air all the time. Reliability of the products are also provided by the high-quality Swedish paint and varnish. The windows binded by the German company “Roto Frank” easily open and close at any time of the year.

“We can guarantee the highest quality and durability of the windows as we ourselves supervise the process of processing wood, manufacturing and installing of windows,” says J. Varkojiene. Being confident that pine wood grown in the conditions of Lithuanian weather is the best for the Lithuanian house, in winter the staff meticulously selects approximately 28 cm thick pine logs and buys the amount sufficient for the following year. Although it requires considerable investment locked for a long time, there is no other choice – pine wood cut down in summer or spring is not suitable for manufacturing of windows.

Beams Are More Reliable

The best windows, according to the director, are made of glued wood beams. Three layers of glued beam is extremely durable and resistant to deformation, because it is bound by the radial cutting boards by using a moisture-resistant adhesive. Because it totally does not leave the branches, such beams do not have even the smallest chance to bend, rotate or split lengthwise and the outer layers of the radial or semi-radial cutting protect the surface of a window or door from cracking. According to the local carpenters, for making windows, the glued three layers of pine, which are removed from the branches, resins and small divisions, or three layers of solid pinewood – the choice of wood without knots – resin and cleavage beam, fit the best. To the warm part of the window the four-layer beam is applied – this leads to even better thermal conductivity properties.

JSC “P. Varkojis ir Ko“ started its operation in 1994. “Constant expansion and rapidly changing technologies create not only a high added value but also ensure jobs to 120 people. We have been trying to prove that we are the best for seventeen years already.

The production of the company i.e. wooden windows, doors, beds and small garden houses are welcomed not only by Lithuanians but also by Germans, Swedish, Norwegians, and English. Our company is introducing a new product, i.e. the pellets, which are clean, natural and environmentally friendly source of biofuel,” Jūratė Varkojienė said; the production of the company can be often seen in different exhibitions. Talking to her clients, Jūratė often emphasizes that trees are a part of the surrounding nature, “It is a material that radiates warmth and coziness. A person, whose environment is enriched with wood, shows the importance of real rather than apparent values.”

“Windows is a part of a building construction which performs most functions. A window keeps away cold, sound and wind, and lets light and fresh air in. Windows have major influence on the indoor climate. Our buyer can choose preferred window color, the type of insulating glass, safe window fittings, ventilation accessories and so on. Our manufactured windows and doors are painted with special paint that is eco-friendly, harmless, has good adhesion with wooden surface, allows the wooden windows to ‘breathe’, and does not crack at wood movement. Our windows are of two types: European standard and Scandinavian standard. European standard windows are adapted to Lithuanian micro climate. Their thermal conductivity is 0.87 W/(m²·K). Our company is the first one in Lithuania to manufacture 92 mm thick windows, which are very popular and valued by our clients,“ Mrs Jūratė rejoiced. The company “P. Varkojis ir Ko“ also produces unique quality doors. “We manufacture doors according to customer’s requirements, which are adjusted only to the client’s home and installed by our company workers. Interior doors are made from pine or ash tree,” J. Varkojienė listed.

The novelty of the company is the production of pellets to be used as fuel. “They are produced from spruce wood sawdust and pressed into small 8 mm in diameter cylindrical pieces. Pellet fuel is clean and eco-friendly. Pellet combustion does not produce any volatile or hazardous materials. When the pellets are burned, little ash remain as they are produced from high quality chips without bark or other waste. Their combustion does not clog the chimney nor furnace,” Mrs J. Varkojiene listed the advantages of pellets; she also emphasized that the maintenance of boilers used for pellets is no different from maintenance of the automatic gas boiler.

Ugnė Šaltenytė, “Vakarų ekspresas”, January 2012. In autumn and winter, when harsh seaside winds start blowing through, one comes to the resolution to change the windows of an apartament with the new ones that keep the warmth inside better.

The JSC “P. Varkojis ir Ko,” which has a lot of experience in wood production, is ready to advice and offer a wide range of practical options.

The Advantages Of Laminated Veneer Lumber

Great offer – three years ago, the company “P. Varkojis ir Ko” was the first one in Lithuania to start producing 92 mm thick windows, the thickness of the glazing unit was 48 mm. Till then the company has been producing another popular standard – 68 mm thick windows. However, as the manager of commerce Jūratė Varkojienė says, investing into production of 92 mm thick windows has become an important step forward, i.e. the new European standard windows quickly became popular among clients.

92 mm thick windows help to keep comfortable atmosphere at home: the window does not allow the summer heat in and does not release the inside warmth out in winter. It also adds to excellent sound insulation. Due to the rising fuel prices, heating of homes becomes a real headache. The so-called warm window becomes a very important aid in daily routine as among all its advantages it also helps to save money. Among the valued features there is four-layer laminated veneer lumber that is used in the production of windows. Such veneer lumber resists cracking, deformation and can withstand heavy loads.

From Paint To Accessories

Before becoming a part of a house or an apartment, windows are properly prepared. They are coated with the water-based ‘Becker Acroma’ paint, which creates an elastic resistant to cracking membrane that protects a window from the long-term atmospheric effects, prevents the penetration of moisture and mold, though at the same time it allows wood to ‘breathe’. In addition to some great protective features, there is a wide variety of colors that you can combine to your home interior and exterior. For these reasons, the 92 mm thick windows perfectly fit in the ‘passive houses’ which prove to be very efficient in the use of energy and heat insulation. Last detail – modern and functional accessories: the windows produced by “P. Varkojis ir Ko” are braced by bindings made by “Roto Frank AG” from Germany. In addition to this new standard for the Lithuanian market, for many years the company has been also producing another usual European standard, i.e. 68 mm thick windows.

Certified Products

The JSC “P. Varkojis ir Ko” gained recognition abroad due to its produced Scandinavian standard windows. The products which have all the necessary certificates are gladly chosen not only for homes but also hotels and schools.

One of the characterisctics of the Scandinavian type windows is that they open to the outside; therefore due to the design features they are especially suited for harsh weather conditions. These windows are called the ‘quietest’ and the warmest and is a unique accent to the log house, cottage or sauna. Different configurations of Scandinavian windows from Lithuania are exported to Denmark, Sweden and Norway.

The company “P. Varkojis ir Ko” also produces a variety of furniture; their beds and chests of drawers are especially popular in Germany. The garden houses are exported to Holland, Germany and England; exterior and interior doors made from different kinds of wood are valued in Lithuania.
