Our Clients Always Come First. We want to show our clients that our windows are not only excellent quality, but also multi-functional and aesthetically pleasing. Regardless of whether your project requires timber, aluclad (composite) or aluminum, we take care of every detail of your order.

We Do Not Manufacture, We Create. Each window is thoroughly inspected in terms of functional features and aesthetic finishes. We do not manufacture windows, we create them for you, and we believe that our creations are truly exceptional. Like how an artist’s work on the creation of stained glass is very meticulous, so is our work on every window and in ensuring the efficiency of each of its components, which requires passion and precision.

We Believe That Our Windows Are Like The Applied Arts Oak timber frames, carved profiles, ornamental glass, solid fittings, chrome handles and double-glazed units. This is just one of the thousands of configurations that we can offer for beautiful interiors. Unique windows and doors are part of our homes; therefore we believe that they deserve that extra bit of attention to ensure perfection is achieved.

We Respect Cultural Diversity. We operate in many foreign markets, and our clients from all over Europe visit our factory on an almost daily basis. Although each of them has different ideas and designs, they share one thing - the desire to have high quality products. That is why on every order

we ensure one of our designated export specialists thoroughly checks and double checks each order to ensure everything is perfect before being exported to you.

We Are Innovative. We work as a team; we listen to our clients’ needs and react quickly to new trends. Our passion enables us to bring even the most complex of projects to fruition.


Our standard lead-time for delivery to residential clients is 4 - 6 weeks, after receiving the confirmed signed order. Our team of specialist installers can install the timber or aluminium windows and doors with high quality sealants and weatherproof seals.

It is very important to hire specialist installers when installing the windows and doors at your home, so that they can check that all the openings are properly sealed and are weatherproof.
