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 glass. 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 cultural 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 glass windows for a comfortable indoor climate. 2 glass is best suited to summer houses, garages and storage rooms.
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.
