Lammin energy windows are available in both fixed and opening models. The fixed window is above all suitable as a large landscape window, the smaller windows are better as opening model. Lammin energy windows are popular in all types of buildings – in detached houses, condominiums and cottages, regardless of whether it was a new building or renovation house.
To save on heating costs, choose energy windows
Energy windows are the right window choice for anyone looking for a lower heating bill and lower emission load. Lammin energy windows not only meet today’s thermal insulation regulations, but also tomorrow’s requirements. The price of energy is likely to continue to rise in the future, and therefore energy windows are also an excellent option in terms of the resale value of a home. Energy windows can be individualized like all other windows with e.g. different colors and window accessories.
