Window Sills
Window sills are practical additions to a high-quality window. They can be adorned with decorations and reliably drain any water that occurs outdoors. A window sill connection profile is required to securely mount an interior or exterior window sill under the window. Ideally, the profile is attached when the window is installed, thus enabling the window sill to be installed later. In particular, effectively sealing the joints is crucial here in order not to negatively influence the thermal insulation.
A window sill connection profile can take on different shapes and is always narrower than the frame of the window. windows24.com offers three types of window sill connection profiles:
While the first type of window sill connection profile is suitable for all new buildings and enables the installation of exterior and interior window sills, the other two profiles are suitable for compensating for a height difference that has arisen due to the previous installation of an exterior window sill.
In order to adapt the interior window sill to the height of the exterior window sill, the window sill connection profile is attached under the window. This is mostly the case with exterior window sills in stone.
On the one hand, these are often built into the facade itself, so that there is no window sill connection profile; on the other hand, a window sill made of stone is significantly thicker than a model made of wood, werzalit or alu.
In order to compensate for the height difference that has now occurred and to enable the installation of an interior window sill, the appropriate type 2 or 3 window sill connection profile is installed, depending on the required height.
Since the profiles are designed to be narrower than the window frame, this allows the interior and exterior window sill to be pushed underneath the window. Careful, professional installation is necessary here in order not to damage the thermal insulation level.
Professional installation ensures the integrity of the thermal insulation.
The installation of a window sill connection profile should be carried out by more technically skilled individuals, especially when renovating. In a new building, installing accessories is comparatively simple. Tips and instructions for DIY installation can be found in the video section, for example.
Here the masonry below the window requires work, which is a sensitive area. Because energy saving has been a top priority not just since the introduction of the Building Energy Act.
Windows, like front doors, are an integral component when determining the thermal insulation in your home and must therefore be insulated all around. Damage to the insulation leads to thermal bridges, which can result in condensation and ultimately even mould.
The insulation is therefore an essential factor when installing a connection profile. Accordingly, a modern window sill connection profile is also equipped with several chambers that take on an additional insulating function.
The structure is similar to a window profile made of uPVC, which also achieves excellent thermal insulation values thanks to its multi-chamber profile system. If a window sill connection profile is installed, care must be taken that the insulation is not affected.
Joint sealing is another point that must be considered following the installation of connection profiles. If the joints are not properly sealed, moisture can penetrate.
Waterlogged masonry is the long-term repercussion. Here, too, the risk of hazardous mould is the end result of what appears to be a small mistake.
A window sill connection profile should therefore always be installed by a professional.
Proper insulation and sealing prevent the formation of moisture and possible mould.
