What Is Curtain Walling?
Curtain walling is an external layer which can be found affixed to the outside of commercial buildings, typically multi-storey constructions. The curtain walling is connected to the building through the floors or columns, and as such is not a structural support, therefore carrying no dead load weight. Previously the majority of curtain walling was constructed from steel, but with the rise in popularity of lighter metals most modern curtain walling is constructed from aluminium.
Curtain walling has become exceedingly popular over recent years. This popularity can be attributed to the system’s ability to cover large expanses, this is due to curtain walling being extremely light weight, making them ideal for use over multiple stories. The rise of curtain walling is due to architectural changes in how buildings bear weight. Previously exterior walls carried the buildings weight, however with the rise of steel and reinforced concrete load bearing columns, buildings exteriors became increasingly decorative, using large amounts of glass.
Typically, curtain walling forms a frame which is like a grid, usually surrounding glass panes, metal and stone panels are not unknown. Refurbishing curtain walling, using the services of professionals, is not as difficult as you may first suspect. These companies can work at height, cleaning and recoating the curtain walling to produce a truly stunning appearance.
Why Recoat Curtain Walling?
A significant amount of curtain walling is constructed from aluminium extrusions which are anodized. In such cases dirt can be problem as a number of cleaning chemicals will ruin this finish. Currently, these is no way of re-anodizing curtain walling in-situ, but recoating provides an excellent means of protecting the metalwork and improving the aesthetics of the structure.
One of the main factors responsible for the deterioration of curtain walling is moisture penetration. This results in moisture seeming from the building’s exterior into the curtain walling’s interior. This process detracts from the practical utility of the curtain walling, namely to protect the building from inclement weather. Recoating curtain walling provides a cost effective means of protecting curtain walling from moisture penetration as the coating creates a waterproof surface which bonds to the substrate.
Gone are the days when paint coatings simply changed the colour of the surface to which they are applied. Modern coatings offer a number of additional benefits such as anti-corrosion and UV light protection. Applying these coatings to your curtain walling not only improves how they look but also improves its longevity.
