Timber-Aluminium Window | Natura®
New sales profile
Soon on the web
Natura® is our latest product manufactured in accordance with modern green-building standards. Chief characteristics of this window are its unique modern design and its profile joining method. Natura® profile meets all the low-energy passive building standards and is ready to be installed in such objects. Its additional advantages are minimal energy loss during all seasons and excellent thermal and sound insulation. Massive timber laminated profile guarantees both internal warmth and comfort of the interior and external durability and protection from the elements.
Natura® is also equipped with five WINDOR® seals specifically designed to provide rain, noise and draft protection.
Natura® windows are manufactured usuing triple ISO glass (4+16+4+16+4). The space between glass panels is filled with inert glass for insulation. Glass is coated with Low-E coating which reflects energy into the building interior. The aluminium external profile part is additionally thermally insulated with extruded polystyrene (XPS).

Equipment and safety
WINDOR® windows are equipped with Siegenia safety casing. Casings can have additional closed-window ventilation elements, which is extremely important due to condensation in newly built objects.Find out more ⇢
Profile sealing is extremely important for humidity, rain and draft damage prevention. For our products, we use safety seals designed in our Product development department. Q-LON seals by the renown Schlegel factory are used for window casements, while EPDM (ethylene propylene diene monomer) seals are used for window frames.Find out more ⇢

In order to maximize energy efficiency, joinery is installed according to RAL guidelines. The space between windows and walls is filled with waterproof, vapor conductive foil on the outer side and vapor nonconductive foil on the inner side. This achieves vapor conductivity and air non conductivity of the interior.
Installation according to RAL guidelines enables free exit of vapor from the interior, while preventing entry of water and rain.
