New line of wooden windows Lumnia
More light. Less frame. Slim profiles and clean, aligned lines allow more natural light into your home and open up the views. Whether you’re building a new home or renovating an existing one. The name Lumnia comes from the Latin word lumen, meaning light.
Get to know Lumnia
We live with our windows for 30 years or more.
A quiet presence that shapes everyday life.
Windows often go unnoticed, yet they play an essential role in our everyday comfort. They determine how much natural light enters a space, frame our views, and contribute to thermal and acoustic comfort. Replacing windows is not a simple undertaking. It requires a significant investment and involves installation work that temporarily disrupts the living environment.
That is why making a well-informed choice matters.
We look for specific qualities in windows. Lumnia is designed with these priorities in mind.
Light
More natural light in every room.
Sense of Space
An open, airy space with unobstructed views of the outdoors.
Living Comfort
Reliable thermal and acoustic insulation.
Protection
Durability and resistance to weather conditions.
Aesthetics
Clean, minimalist lines with flush-aligned profiles.
Low Maintenance
High-quality materials that retain their appearance over time.
Why Renovations Are Different
Replacing windows often means losing some natural light.
In a conventional renovation, the size of the existing window opening is usually fixed. At the same time, several factors can reduce the amount of natural light entering the room, often without us even realising it.
Installing a new window requires approximately the same amount of space on each side of the opening.
Upgrading from double to triple glazing can reduce light transmittance.
Shading systems, insect screens and other accessories require additional space around the window frame.
Modern window profiles are often wider. Lumnia reduces the visible profile width to approximately 6 cm, making a noticeable difference.
Lumnia effectively compensates for this loss. Its slim profiles maintain high thermal performance while allowing more natural light into the room and creating a greater sense of openness.
More Light, Less Frame
A slimmer frame means more glass and more natural light.
In renovation projects, the aim is not to enlarge the existing window opening, but to maximise its potential. The key lies in the ratio between the frame and the glass area. The comparison below illustrates the difference between a standard window profile and the slim Lumnia profile. These advantages are equally relevant to new-build projects.
Lumnia is designed around one key principle: maximising natural light and providing the clearest possible views within the existing window opening. This is achieved through a carefully engineered profile, without the need for structural modifications to the building.
Reducing the visible frame width increases the glass area and allows more natural light to enter, without changing the size of the window opening.

Tested and Certified Sealing Performance
In official tests conducted by the ift Rosenheim Institute, Lumnia windows achieved air permeability Class 4 and watertightness Class 9A, the highest classifications in their respective categories..
