Passive House certified and eligible for funding

What is the passiveHouse about

Passive houses are buildings that use the energy of solar radiation for their heating - for example through large C-windows.

In addition to the solar gain, passive houses also include:

the avoidance of thermal bridges
airtight building components such as the roof and floor slab
a ventilation system with heat recovery
thermal insulation of the building envelope
as well as passiveHouse_Windows

Save up to 3 months on heating costs

The special profile design and high-quality triple glazing of Salamander passiveHouse_Windows

ensures good insulation
keeps the heat in the house
contribute to a pleasant indoor climate
can help reduce heating demand and support efficient energy use as a result

The grey areas show it clearly: in a Passivhaus, the heating period doesn't start until October and already ends in March. For a standard house, the chart shows a correspondingly longer heating period.

A modern house with large windows is surrounded by snow-covered trees and a snowy landscape at night.

Winterizing your windows

How to prepare your windows for the cold season!

When it gets colder outside, it's the right time to prepare your windows for winter. Small adjustments to the fittings, clean seals, and an adapted ventilation routine make all the difference: they keep the heat in the room, prevent drafts, and provide reliable protection against moisture and mold. The so-called winter mode plays a particularly important role here – it regulates the contact pressure between sash and frame and provides a high level of airtightness. In this guide, you will learn how to optimally prepare your windows for winter, which measures are really effective, and how modern systems from Salamander myWindow can help you save energy and increase your living comfort.

Window subsidies in 2026: BAFA, KfW, and tax benefits explained simply

iSFP window bonuses, or KfW certification could be particularly worthwhile in 2026: if you plan cleverly, you can receive government support for window replacement or new exterior doors—and benefit from tax advantages at the same time. Below you will find a compact overview of funding opportunities, requirements, and steps—including recommendations for your home.

Advantages of the Salamander passiveHouse_windows

Efficient thermal insulation

Energy-efficient window profiles with an evoCore insulation core help reduce the ecological footprint.

Environmental benefits

To further improve insulation, we use thermally broken steel.

Simple recycling separation

The insulation core can be separated from the plastic profile. This means that both materials can be recycled separately.

Simple configuration

With evoCore and thermally broken steel, the window becomes a passiveHouse_Window very easily.

evoCore and thermally broken steel -
Nobody else has that

With evoCore and thermally broken steel, our windows increase insulation value, reduce the energy consumption of your home and are more environmentally friendly in transportation thanks to 25 % less weight. The easy separability of the plastic profile and PET core enables 100 % recycling.

Using recycled foam as an alternative to steel from energy- and material-intensive production can help reduce the ecological footprint.
The fRsi value can be improved through evoCore.
