About Weru: premium German engineering since 1956

Weru is one of the most prestigious brands on the European window market, founded in Germany in 1956. Its Afino-Tech system is modular and adaptable to every opening type and configuration. With 76 mm frame depth, 5 chambers and a Uf value of 0.9 W/m²K, Weru delivers thermal performance on par with the best Passivhaus-certified windows. It's a top-tier product used in landmark architectural projects. Its weak point is the price, which puts it out of reach for most standard residential budgets.

Our experience with Weru (Afino-Tech) windows

Weru is a brand we reserve for distinctive architectural projects. Its Afino-Tech system competes with the very best windows on the European market, with a level of customisation we don't find anywhere else.

Weru's pricing puts it beyond the reach of most standard residential budgets. We install it when the homeowner or architect specifically requests it.

Along the Costa Brava we've fitted it in luxury seafront homes and premium architectural projects where the rest of the build justifies the investment.

Modular customisation without parallel

Weru offers levels of customisation that other brands reserve for special orders: unique colour combinations, hidden hardware, made-to-measure profiles and premium finishes outside the standard catalogue.

This explains the longer manufacturing lead times (6-10 weeks) but also Weru's presence in top-tier architectural projects.

Our rating of Weru (Afino-Tech) as installers

4.4/5
Weru Afino-Tech is the absolute premium choice — we reserve it for top-tier architecture

Weru sits at the very top end of the European window market. Its Afino-Tech system combines Passivhaus-grade thermal performance (Uf 0.9 W/m²K) with a level of customisation no other brand offers as standard. It's the brand we recommend when the rest of the project justifies the investment: luxury homes, distinctive architectural projects, budgets without restrictions. For standard residential renovation, there are more cost-effective options.
