What Is Building Wrap-In Construction?
Building wraps are a popular technique used to conceal scaffolding during construction projects. They are large-scale printed sheets that can be fixed to the scaffolding structure, and they are typically printed with a CGI rendering or photographic image of the building façade.
The aim is to blend in better with the building’s surroundings and provide a tantalizing representation of what the completed building will look like.
Building wraps have numerous advantages, including their ability to reduce the spread of dust and debris, conceal construction work from the public, and minimize the impact of the under-construction building on the surrounding environment.
The scaffolding structure must be securely erected to ensure the installation of the wrap is safe. Engineers may need to calculate wind loading to ensure that the wrap will not become a hazard to the scaffolding.
The typical method of installing building wraps involves a picture frame scaffolding structure that projects approximately 300mm further out than the last projected pole on the main scaffolding.
The wrap banner is usually fixed using either a standard method, where the banner sits inside the frame and is fixed using bungee cables, or an invisible method where the banner is pulled completely smooth over the outside of the picture frame scaffolding and clamped using clamp couplers/joins.
The invisible method is generally thought to provide a better appearance.
The scaffolding picture frame is usually installed before the wrap is printed, so the template can be accurately measured to ensure the wrap covers the scaffold completely and is taut enough not to crease.
Building wraps can also be used as a discreet form of advertising, but they may require planning permission from the local authority.
Overall, building wraps are an excellent solution for concealing unsightly scaffolding during construction projects. They have numerous benefits, including reducing the spread of debris, concealing construction work from the public, and minimizing the impact on the surrounding environment.
However, engineers must ensure that the scaffolding structure is securely erected and that the wrap is installed using the appropriate fixing method to ensure safety and a seamless appearance.
Building wraps are usually printed in 4-meter-wide sections, which are then laser trimmed and welded together in a factory using an ultrasonic welder.
Heavy-duty brass eyelets are installed around the banner’s edge into a 50mm reinforced welded hem. These wraps are made of a mesh material, allowing light and some wind to pass through them.
To achieve a tight and premium finish, the building wrap is typically attached to a frame that extends away from the main body of the standard scaffolding. This method ensures that the banner is taut and does not sag.
In addition to being secured around the perimeter of the banner, hidden fixings (referred to as “dragon tails”) run vertically down the inside of the banner, allowing the banner to be tied back to the scaffolding structure at multiple points.
Unlike heat shrinking, a mesh building wrap is tensioned using ropes and bungees. This technique ensures that the banner remains tight and secure, providing a high-quality finish that meets clients’ expectations.
Why Do They Wrap Buildings?
Building wraps are a crucial part of ensuring building longevity, as they act as both a physical and weather-resistant barrier while keeping their contents safe from rain or moisture.
The wraps allow water vapour to pass through to the exterior, while prohibiting it from penetrating any wall assembly, providing an extra layer of protection against the elements.
Furthermore, the wrap also adds an additional insulative layer which helps buildings retain heat in colder climates and divert sunrays away from windows in hotter ones.
In conclusion, building wraps serve numerous purposes for buildings everywhere be it apartments or commercial installations; and contribute significantly towards preserving these structures for many years to come.
How Long Do Building Wraps Last?
Building wraps are a great way to create vibrant and eye-catching visuals for your business and can provide excellent visibility. The longevity of such wraps, however, depend on their environment as well as the quality of installation.
In general, building wraps typically last anywhere from two to five years – though local environmental factors can affect its life span such as humidity levels and UV exposure.
Quality anchors will also help ensure the wrap is securely in place throughout its lifespan, helping it to look better longer.
