VELUX roof windows
The service in detail
A roof window brings light, air and a sense of space where it was once dark and cramped – turning your attic into a room you actually want to live in.
As a master roofing business, we plan and fit your VELUX roof windows entirely from a single source – from choosing the right model to an airtight fit, through to the interior lining and matching sun protection. The result is a bright, well-ventilated room that feels good to be in.
Whether it's a new window in a previously unused attic or replacing an old, leaking one, we pay close attention to an airtight and watertight connection with the roof covering. That keeps out draughts, moisture and heat loss, and creates a healthy indoor climate that lasts for years.
We work throughout Luxembourg – from Mertert, Wasserbillig and Grevenmacher to Echternach, Remich and Wormeldange, all the way to Junglinster and Luxembourg City. For anything involving the roof structure or carpentry, our sister company Blang Holzbau is there to help.

Frequently asked questions
The cost depends on the model, size, glazing and fitting situation – a single window is calculated differently from several at once. After a short visit on site, you receive a clear, free quote with no hidden items.

As part of an energy renovation, the reduced rate of 3% may apply. We'll review your situation and advise you on the conditions involved.
Of course. We replace seals, repair leaking connections or add sun protection and shutters – even without replacing the whole window.
