As Smålanders, we cannot ignore the price of the product. Naturfönster wants to offer durable wooden windows at a good price and we know that our prices can be compared. We try to do everything ourselves, which keeps the price down. We don’t have any dealers, we don’t keep any stock, we have our own transportation with our own cars.

Another important point is that we hardly advertise our products. Advertising costs money and the price for that has to be added to the final product. We sell almost exclusively on recommendations from previous customers and from our skilled partners who install our windows.

Wooden windows from Naturfönster: quality for generations. But which wooden window should you choose? Wooden windows with glazing bars?

It depends first and foremost on what house you have, older houses, then you choose one of our cultural windows, modern houses, then Natur’s turning windows become relevant Then comes the energy issue and the choice between 2 glass and 3 glass windows. Do you think the energy cost will be lower or higher than today. Probably higher, right? You should future-proof your house. Buy new modern extra insulated 3 glass windows with modern low emission glass. Then it depends on which house you buy.

For your home, the house where you live all year round, you should choose 3 glasses. Both for energy savings, comfort and not least for sound insulation. You should also bear in mind that energy costs are unlikely to be lower in the future. You should future-proof your wooden windows and you do this with Naturs windows and doors. If you are going to live in the house all year round, you need 3-glazed windows for a comfortable indoor climate. 2-glazed windows are best suited to summer houses, garages and storage rooms.

Naturfönster’s 2 glass wooden windows

Naturfönster’s 2 glass windows have a good gap between the glass for better insulation, and we fill the glass with argon gas. Argon makes it more difficult for the cold to migrate from the outside and through the glass package into your house.We also coat the outer glass with a thin metal film, a so-called low-emission surface that helps the sun’s light and rays to travel through the glass, but which makes it difficult for the room heat to radiate through the glass. That’s why Naturfönster’s 2-glazed windows with energy glass are better insulated than 3-glazed windows were just a few years ago.

The same goes for our 3 glass windows, they also have low emission glass and argon between the glasses. Naturfönster’s 3 glass windows are 50% better insulated than 3 glass windows were just a few years ago. If you install Naturfönster’s energy windows, you should therefore also review your ventilation in the house.

Our wooden windows provide such good insulation that no air can slip through as it did in your old windows. This stolen air provides ventilation to the house and if you do not have additional vents in the house, you should install it when you switch to our windows and doors.Feel free to choose a valve in your new Naturfönster.

Naturfönster manufactures wooden windows with heartwood

Good ventilation together with good windows is important for your well-being and to keep your energy costs low. A very good option is to buy Naturfönster’s gap valve in the windows. We then build an extra valve into the window that provides fresh air and ensures that you and your house feel good.

When replacing windows, consider the environment too. Naturfönster manufactures wooden windows from slow-grown pine. Wood or a natural material that is biodegradable. The fact that we then manufacture our windows by hand with great craftsmanship and love guarantees quality that lasts for generations.

Wooden windows with glazing bars, in all sizes.

In addition to durability, one of Naturfönster’s strengths is design. Our beautiful wooden windows are available with a variety of options. One of them is glazing bars. You can choose from these different glazing bar options with us. Genuine glazing bars. Natural glazing bars are surface-mounted with spacers between the panes. They are often called Viennese glazing bars.

The advantage is that they are just authentic, they have a wooden mullion both on the outside and inside of the glass with an aluminum spacer between the glasses. The old-fashioned charm of the window is enhanced. Naturfönster recommends Äkta spröjs on Kulturfönster, Allmogefönster, Traditionsfönster.

Nature Removable glazing bars

Nature Removable glazing bars, easy to clean. We also call them natural glazing bars. Another great advantage is that you can easily change the look of your window and house. If you get tired of the bars, just remove them, then you can put them back in when the mood strikes.

Transom 2+1 coupled windows: Naturfönster manufactures coupled windows and if you choose transoms on these which we highly recommend to get the old look of your windows to suit older houses, the transoms are on the outer glass, double glazed inside and outside. The single glass inside is without glazing bars.

Continuous glazing bars, dividing glass. Windows with continuous glazing bars can be beautiful. Naturfönster can manufacture windows both with continuous mullion (which is wider than transom) and with glass dividing mullion. The disadvantage is that the window has a poorer u-value, insulation value and it takes light.

Aluminum bars, or so-called szr, are located between the glass. The advantage is that there is only one glass surface to clean, the major disadvantage is that the window has a poorer uvalue because the aluminum cools the glass. There is also a risk of gas leaking into the glass cassette. We do not provide an extended glass warranty for aluminum bars between the glasses.
