2. Preparing the Patio Door
In order to avoid shipping damage, special protective foils are applied to the exterior surfaces of patio doors and windows. Before installing your patio door, remove the foil from the parts of the frame that will be attached to the reveal, as removing the foil afterwards may prove to be very difficult. All other pieces of foil should only be removed after installation. (Fig. 2b).
- Attach the handle in the correct position on the door and open the leaf. (Fig. 2c).
- Lift the leaf out of the frame. In order to do this, the upper security pin can be removed in a downward motion using a slotted screwdriver, enabling the leaf to be lifted upwards out of the hinges. (Fig. 2a).
- Place the leaf on soft padding material. Massive aluminium patio doors can easily damage wooden floors during installation, while the surfaces of wooden, aluminium and uPVC leafs may also cause damage or be damaged themselves. When all preparations are finished, the actual installation of your patio door can begin. The average installation time for a patio door is about two to three hours.
a) Inner Seal
The inner sealing level effectively separates the interior and exterior climate conditions. The seal must be resistant to vapour diffusion - stopping the diffusion of water vapour through the door. Usually, at this level, you should use vapour-resistant foil or acrylic jointing for installation (Fig. 3a).
b) Middle Seal
The central space between the wall and the patio door frame is called the middle sealing level. To provide good thermal insulation, it is essential to completely fill this area with insulating materials. Polyurethane construction foam is most commonly used. Other fillings, such as cotton fibre and mineral fibre materials, are alternative solutions. People suffering from allergies may want to be careful in their choice of insulating material, as polyurethane may cause allergic reactions. Using other filling materials is more sensible in such cases (Fig. 3b).
c) Outer Seal
The outer sealing level provides the profile of the new patio door with long-term protection from inclement weather. In accordance with ISO standards, this seal must be rain-proof and open to vapour diffusion at the same time. Foils and pre-compressed sealing tapes can meet these requirements quite easily. Sealing the joints with silicon is also possible (Fig. 3c).
Proper seals not only ensure good thermal insulation, they also protect the interior of the masonry from weather damages in the long term. Once you have chosen the appropriate sealing materials for the different levels, you can easily order them via the windows24.com accessories shop.
