Aluminium is frequently used for the formation of windows and doors for a variety of reasons. Bearing in mind it is a metal, aluminium is extremely lightweight, yet, its greatest attributes are its durability and its ability to withstand corrosion. As doors and windows are commonly exposed to the weather, this is vital.

Though aluminium is a perfect material for exterior functions, to keep heat indoors and cold and moisture out, sealing solutions are key. Without having aluminium seals for doors and windows, houses and workplaces would be subjected to draughts, rattling windows and water leaks in wet conditions. Window seals are most often manufactured from rubber and plastic substances, such as thermoplastic elastomer, thermoplastic polyurethane, PVC, and Nitrile rubber.

If designing door and window seals, it's important to choose sealing materials that are intended for outdoor environments and sealing applications. For exterior windows and doors, a resistance to UV, ozone and normal abrasion is a must, along with good elasticity and compression set capabilities to supply a tight seal and become an insulator from the elements. Improperly sealed doors and windows are less probable to prevent draughts and are more likely to create a build-up of damp between double glazing panes or around a door.

How are aluminium seals created?

Often, door and window seals must have a consistent cross section to ensure all places are properly sealed. A good way to accomplish this is to employ an extrusion process, where the raw rubber or plastic material is pressed through a specially designed die using the correct cross section. Seals will then be cut down to size to deliver an accurate length to match each window or door.

Replacing aluminium seals

Although aluminium door seals are designed and produced to be resilient solutions against draughts and damp, based on material applied, gradually seals and extrusions may fail. Many manufacturers of doors and windows use standard or very similar styles of aluminium seal and for that reason, failed seals can simply be replaced with little issue. In some cases, a direct replacement can be found in stock, or at the very least, an appropriate replacement can be obtained by informed staff if you provide them with a sample.

As the most difficult venture is often acquiring the best aluminium seals to fit a particular window or door, depending on the specific design of an extrusion, seals may vary in how tricky they are to replace.

E.g.:

• Simple �bubble' seals are typically very easy to replace. Because of the simple cross section of the extrusion, the existing seal can be drawn right out and substituted with the new. • On the other hand, an �E' gasket, also frequently used as an aluminium seal, is one of the hardest extrusions to replace as they are clipped into a window frame.
