Insulated Upstand - Base for Roof Waterproofing & Flat Roof Window

Step by step: Install upstand, seal, and prepare roof window

The upstand curb forms the defined base for roof waterproofing and window support. With suitable connection and mounting components, the connection to the roof waterproofing can be carried out cleanly and reproducibly – matched to product size and roof structure.

Note: Screws/fasteners and on-site sealing membranes (e.g., EPDM/bitumen/foil) are – depending on the substrate – not automatically included.

1.

Prepare components

Lay out all set components ready for use. Ensure surfaces in the connection area are clean, dry, and load-bearing.

2.

Check upstand/opening

Construct upstand / substructure according to roof structure and check for evenness. Account for tolerances for stress-free installation.

3.

Apply glazing tape

Place the structural glazing tape stress-free and all-around on the intended support surface – as a defined, damping support.

4.

Apply sealant

Apply sealant all around according to manufacturer's instructions. Ensure clean joints, sufficient layer thickness, and continuous sealing.

5.

Install roof connection

Integrate the connecting strip/flashing system-appropriately into the roof waterproofing so that water is safely drained and the connection remains permanently sealed.

6.

Install skylights

Install, align, and seal the roof window according to the installation instructions. For warranty and watertightness requirements, installation according to the manual is decisive.
