More natural light at home? Installux aluminium solutions make all the difference

22/12/2025

Is your interior lacking in brightness? With the right joinery, you can transform the ambience of a room without redoing everything. Installux aluminum solutions maximize glazed surface area to let light in... while maintaining excellent comfort.

Everyday comfort

Natural light changes everything

Before talking about solutions, a simple reminder: natural light is a real lever for well-being in the home. It makes you feel better every day, reduces visual fatigue and enhances volumes, colors and materials. In winter, it also helps to naturally warm certain rooms and reduce the use of artificial lighting.

  • Well-being and visual comfort
  • Warmer ambience
  • Less artificial light
  • Visually enlarged rooms
The right material

Aluminum, the ally of brightness

There's a very practical reason why aluminum is so attractive when it comes to light: it allows for slim, robust profiles. The result: the more discreet the profile, the greater the glazed surface... and the more light that enters.

Installux highlights

  • Fine mullions and transoms, to maximize glazing clear
  • Performance glazing, to enjoy light throughout the seasons
  • Customization (colors, openings, integration) to suit each room
  • Panoramic sliding windows, composite units, skylights : many possible configurations

Did you know?

Thanks to thermal breaks, you gain in light without losing in comfort.

Tricks

5 ideas for bringing light into your home

Large sliding bay window

Open up the room to the outside, gain glazed surface area.

Compound packages

Mix fixed + operable to visually enlarge a facade.

Interior skylight

Circulate light between two spaces.

Glazed facade wall /large windows

Maximize light in key areas (living room, kitchen).

Luminous extension

Create a room bathed in light (depending on project).

Make the most of a sliding bay to let in more light

An aluminum sliding bay is often the first "grand gesture" that changes a room: it increases the glazed area and creates a more fluid visual passage between inside and outside. It's also a practical everyday solution: the opening slides, without encroaching on the space.

Optimizing a facade wall with compound sets

When a room lacks light, you can also work "smart": add a fixture, widen an opening, combine several frames... Composite sets make it possible to gain clarity, while respecting the balance of the facade wall.

Create a skylight to let the light in

Sometimes, light is there... but it remains blocked. An interior glass roof is an excellent option for brightening up a hallway, entrance or enclosed kitchen, without losing the feeling of space. And since aluminum allows for slim profiles, the glass roof remains elegant and very bright.

Your questions about daylight

Does a large glazed surface mean less insulation?

No, if the joinery is well designed. Aluminum solutions with a thermal break allow you to gain in light while maintaining a very high level of comfort.

What solution should I choose if I don't want major work?

An interior glass roof or a composite set (addition of a fixture, adaptation of an opening) can already change the atmosphere without transforming the whole house

.

Where to start to avoid mistakes?

Through a simple diagnosis: which rooms lack light, at what times of day, and which openings are possible. A carpenter can then suggest the most suitable configuration.
