Heritage aluminium window shapes are designed to satisfy these demands while surpassing the thermal and acoustical performance requirements of contemporary building codes. Because of its structural stability, thin frames, the polyamide thermal cracks that improve insulation, aluminium is a better material for window frames. Older homes without insulation on the walls and floors will particularly benefit from this. In contrast to wood, which needs to be painted frequently and is prone to decay, aluminium requires less upkeep. Its superior powder-coated finishes provide durability which timber cannot match, lasting for decades. Aluminium is an ecologically friendly material since it is also very recyclable.
Selecting profiles that are respectful of the existing building is essential for incorporating traditional aesthetics in a house. Stepped profiles, putty-line aesthetics, and slim sightlines may all mimic the appearance of steel or wood windows. Custom historical aluminium collections with different sash levels, mullion widths, or outer frame layouts are available from certain manufacturers. Georgian windows utilise aluminium frames made for applied or true glazing bars, Edwardian casement windows have flat profiles, and Victorian bay windows need vertically sliding sash frames.
Important parts of windows that stop drafts, water intrusion, and rattling are weather seals and gaskets. UV radiation and temperature fluctuations can cause them to dry up, break, or shrink over time. Seals should be changed if they seem brittle or exhibit wear, and routine checks are advised. Compatible materials that mimic the historical look and functionality can be used to replace modern seals. Custom hinges, knobs, stays, and locks constructed of sturdy materials are frequently seen on heritage aluminium windows. It is advised to regularly lubricate using a mild silicone-based lubricant to preserve smooth operation and avoid jams or squeaking. Checks for tightness and any corrosion or degradation should be fixed right away.
The painted or powder-coated coatings of aluminium windows are essential to both their visual appeal and durability. But with time, particularly under abrasive conditions, they may fade, chalk, or scrape. It is recommended to clean and apply a protective shine to frames that have been powder coated. Restoration creams could be necessary for anodised finishes. Though adding secondary glazing or insulation films may be explored to improve energy efficiency, routine maintenance can help offset these difficulties.
