Double-Glazed Wooden Windows
Double-glazed wooden windows offer a good balance between insulation and affordability. They consist of two glass panes with an air or gas-filled space in between, reducing heat transfer.
Triple-Glazed Wooden Windows
These windows provide superior insulation with three glass panes and two insulating spaces. They are ideal for very cold climates or for those seeking maximum energy efficiency.
Accoya Wooden Windows
Accoya is a modified wood species that is exceptionally durable and stable. It offers excellent insulation and requires minimal maintenance.
Thermally Modified Wood Windows
This modified wood is treated with heat to enhance its properties. The result is windows with good insulation and resistance to warping.
Composite Wooden Windows
These windows combine a wooden core with a protective outer layer of aluminum or vinyl. They offer the warmth of wood with the durability and low maintenance of modern materials.
