Advice before the choice
We listen to your home, wishes and timing before suggesting products.
Tight, tailor-made protection
Aluminum folding work
Sustainable finish for window details, roof edges, facade connections and other architectural transitions.
Well-thought-out customization
A solution that is right for your home.
Aluminum sheet and folded work forms a sleek, durable finish around windows, doors, facade edges, roof edges, water barriers and transitions between materials.
Length, shape, thickness and color are made to measure exactly. The structure can be combined with a control structure and PIR insulation and invisibly glued for a finish without visible fixings.
Precisely folded for the structural connection
Durable and low-maintenance
Color and shape matched to joinery
Aluminum folding work
Precisely folded for every construction detail
In contrast to flat sheet metal, folding is machined into specific angles and shapes. This means it fits precisely and permanently protects sensitive areas against rain and wind.
Aluminum is light, strong, colourfast, corrosion resistant and requires little maintenance. The suitable thickness is chosen according to length, placement and technical load.
- For indoor and outdoor applications
- Customization in shape, thickness and color
- Can be combined with insulation and joinery

Clear answers
Frequently asked questions about aluminum folding.
Your project may have different technical requirements. During the measurement you will receive advice for your specific situation.
For which applications do you make pleating?
Window and sill connections, roof edges, facade details and cover caps, among other things, can be made to measure.
Is custom color possible?
There is a wide choice of finishes. We look at which color is technically available and visually fits.
What is the difference between folding and flat sheet metal?
Flat sheet metal remains unprocessed; pleats are machined into project-specific angles and shapes. This makes it fit more precisely to window openings, eaves and facade details.
Where is aluminum folding used?
Common applications include window and door finishes, water hammers, roof and facade edges, cover caps and transition zones between materials.
What thickness of aluminum is needed?
The suitable thickness depends on length, shape, mounting, wind load, indoor or outdoor use and desired flatness. Cose determines this per detail.
