The Softline Series steel window sill is an excellent product made of high quality steel sheet coated with PVC veneer designed for use outdoors. Window sills are protected against corrosion, UV, damp and temperature variations. Extraordinary quality at a reasonable price. Softline steel window sills are designed for installation with PVC, wood and aluminium windows. They have been designed for comfort and durability, as well as intuitive installation, and are available in attractive colours, such as golden oak, walnut, macore and wenge. User-friendly and very easy to clean, window sill caps (left + right) must be purchased separately.
The installation method and location of a window sill can lead to fungus or mould formation as well as so-called 'thermal bridges' (local reduction of thermal insulating power). So, certain principles need to be observed during sill installation.
The sill should protrude approximately 30–40 mm from the wall. It should be attached to the so called 'T-moulding', which is permanently screwed to the lower part of the window frame. Using the T-moulding, it is possible to correctly seal the window reveals.
If the window sill is installed with a PVC or aluminium window, the window sill flange should be placed under the window reveal T-moulding.
When installing a wooden window, check if the sash frame member (stile/rail) features a factory-made notch used to mount the window sill. If there is no such notch, a 'wall chase' should be made.
Steel sills exhibit low linear expansion and therefore window sills up to 6 running metres can be installed without using an 'expansion joint' ( the space between two adjacent surfaces that allows for their independent static work and deformation).
Window sills are installed with PVC double-sided caps. At the front of a building the caps have a closed slot that is used to drain water outside in order to avoid wall cracking.
Polyurethane glues are used during window sill installation.
Remove the protective film immediately after the installation.
All necessary accessories required for proper installation of window sills (including double-sided caps) can be found in our shop under 'Accessories'.
