a) How to Install the "Inner" Seal
This layer separates the exterior from the interior climate. When working with French doors you can work with vapour resistant foil or acrylic jointing (Fig. 3a).
b) How to Install the "Middle" Seal
This layer is the primary element for thermal insulation. It needs to be filled with insulating 1-component-PU construction foam. In order to prevent allergic reactions, it is also recommended to install filling materials, such as cotton or mineral fibres (Fig. 3b).
c) How to Install the "Outer" Seal
The "outer" sealing is very important, as it protects your home from atmospheric influences. This is the reason why it must be constantly impact rain proof and open to vapour diffusion. The insulation is normally achieved with pre-compressed tapes, silicon jointing or foil open to vapour diffusion (Fig. 3c).
It is important to install high quality insulation materials correctly, to save money on energy in the long term. The accessory shop of windows24.com offers the right materials for all types of sealing for the installation of windows and French or patio doors.
