As is the norm in Germany, this window is inward-opening, tilt-turn only.

Further Details:

Our range of tilt-turn German wooden windows is something a bit special. The secret to the quality of all of our products is good materials. The IW series standard wooden window achieves outstanding durability – requiring a much lower schedule of maintenance than a traditional wooden window. Furthermore, the process of heat treating results in significantly improved thermal performance.

The IW series is our best selling wooden window. Presenting the option of a standard or flush finish, this standard wooden window features a nylon-coated rubber seal and a rain rail with a large antechamber. This highly engineered timber product is a very popular choice for both domestic and commercial projects.

Like many of our products, the IW series has an inward-opening tilt turn mechanism – designed for both 68mm and 78mm profiles. Optional features include security, performance and safety enhancements.

We offer the finest selection of styles with the possibility of many types of timber, Victorian and Georgian glazing bars. Oak, meranti, walnut, eucalyptus, larch, slow grown softwood and spruce are all available.

In addition, our huge variety of available stains and finishes enables us to provide a very impressive range of natural finishes. Indeed, any RAL colour is achievable internally or externally on a painted finish. Our automotive style painting process then finishes the product in an exceptional way to deliver a wooden window that requires lower maintenance. Plus, if it’s a unique finish you are after, we can also offer anodised windows.
