34 timber windows, Lisbon

The project

We gave this building a new life with 34 timber windows built to last decades. From first contact to the last installation — 8 weeks.

What sits behind every window

• Nordic pine
• A 5-layer Adler finish, protecting against Atlantic moisture and the UV typical of the Portuguese climate
• Guardian glass, a European reference in thermal performance
• German Roto hardware, a guarantee of precise operation for decades

In a timber window, the difference between a 15-year and a 50-year service life is not the species of wood — it is the layers you do not see: the finish, the glass, the hardware and, above all, how well every component fits together.

That is why at SKLO we treat every window as a system, not as a product.
