Aluminium Frame Finishes for Timber Replacement

Aluminium frames from Sieger can be coated in a range of standard RAL colours as well as specialist finishes to create the desired design for each individual project. This enables each aluminium system to be tailored towards the design of the project to complement the building’s aesthetics.

Timber frames for glazing are widely used on both new and existing buildings to achieve a traditional aesthetic which is classically seen on many period properties. Like aluminium frames, timber frames can be finished in a range of colours, however, the timber frames require regular maintenance to apply top-up coats of paint or wood stains to protect the frames from wood rot and water damage.

The main downside to timber framed glazing systems is in the amount of maintenance they require, however, another downside could be in the limitations of frame size as timber frames need to be a certain size in order to support the weight of the glass within the system.



Aluminium is a modern solution for the frames of glazing systems, the strength of the aluminium allows for sleeker appearance to the frames as slim frames are achievable. Aluminium is a highly desirable frame material due to its durability, ease of maintenance and installation.

Just like timber frames, the aluminium frames can be finished in a whole choice of RAL colours and specialist finishes, which are applied as a polyester powder coat. Once these PPC colours are applied the aluminium is protected from rust and most weathering, which results in a little to no maintenance being required throughout the lifetime of the frame systems.

If timber is the desired appearance but the performance and low maintenance is a key element within the design of the property then a sublimation coating can be applied to the aluminium frame – sublimation coatings create a timber look effect to the framing. For further information about the choices of sublimation, finishes speak to a member of the team who will be able to offer further information about these timber effect finishes.

Timber replacement glazing can be designed to match existing areas of glazing that are not being replaced on a property. For example, if a property was undergoing an extension and the homeowners wanted to keep the glazing on the existing areas of the property and install new glazing to the extension, the Sieger Systems can be manufactured to provide a close colour match to the existing glazing.

Sieger Systems are available in a whole host of finishes including brown/colour matched PPC (Polyester Powder Coating) for a dark timber look, whilst a white PPC can be applied to the aluminium to match existing white framed glazing systems.

Previously, the disadvantages of aluminium frames were in its thermal performance values, but due to the advancement of polyamide technology, these systems have come on leaps and bounds and now provide outstanding levels of thermal performance.
