Antikhaus is a specialist manufacturer of windows and doors for historic and heritage-listed buildings. We combine traditional craftsmanship with modern engineering to create solutions that are historically accurate, technically advanced, and built to last.

Our work follows one core principle: the harmony between façade and window must be preserved — without compromise.

Every building has its own requirements, and every client has their own priorities. What distinguishes Antikhaus is our ability to combine both restoration and faithful reproduction of historic windows and doors within a single project.

Where original elements can be preserved, we restore them with the necessary care and precision. Where this is not possible — due to damage, loss, or structural necessity — we produce exact window replicas that match the original in profile, proportion, detailing, and surface finish. The result is a seamless integration of restored and newly manufactured elements, indistinguishable from one another on the completed façade.

This dual expertise means that our clients work with one specialized partner for the entire project scope — with consistent quality, appearance, and craftsmanship throughout.

At Antikhaus, durability is not a promise — it is the result of the way we build. Every window and door is manufactured to standards that go far beyond industry norms: precision-milled profiles, carefully selected materials, and surface finishes designed for long-term performance.

Our linseed-oil-based finishes deserve special mention. We use traditional linseed oil coatings that penetrate deep into the wood and protect it from within, rather than merely forming a surface layer. The result is a finish that is not only more durable and weather-resistant than conventional paints, but also gives each window the authentic, refined appearance required by historic façades. Over time, these surfaces age naturally and gracefully — exactly as they should on a heritage-listed building.

For acrylate paints and stain systems, we apply a four-stage coating system: end-grain sealing, deep impregnation of the substrate, application of a primer or base coat, and application of the final topcoat in paint or stain with a wet film thickness of approximately 300 µm. This provides sufficient protection against weathering, UV radiation, and mechanical stress while preserving the desired aesthetic qualities of the surface.

This commitment to quality at every stage of production means that our products have a significantly longer service life than standard alternatives. For our clients, this directly translates into lower maintenance costs and lasting value.

Historically faithful profiles — Exceptionally slim timber sections that replicate original sightlines and proportions.

Weather bars — Made from a single piece of wood, with direct connection to the glass.

No visible industrial joints — No V-grooves, which are commonly used today to accelerate window production. The joints in the frames and sashes of our windows are smooth.

Linseed-oil-based finishes — Traditional linseed oil coatings for superior durability and an authentic historic appearance.

Advanced security — Burglar-resistant windows up to RC 4 and bullet-resistant constructions up to FB 4 nS — in the slimmest possible profiles.

Custom manufacturing — Each window is developed in close collaboration with clients, architects, and heritage authorities, based on the original windows and the architectural requirements of the façade.

Built to last — High-quality materials and precision manufacturing for a product lifespan that significantly exceeds that of standard windows.
