The Importance of Building Envelope Sealing
Buildings are more than just a roof over our heads. Whether we talk about residential, industrial, commercial or public institutions, buildings are designed to fit the specific needs of the people inside. Innovative tape solutions can support visionary architects and contractors around the world because they play a key role in helping to deliver the ultimate building envelope.
In this blog article, we’ll explore the importance of the building envelope and the role of foam and tape solutions in creating energy efficient living spaces for today and the future.
The term “Building Envelope”, or building enclosure, describes the part of any building that physically separates the exterior environment from the interior. In other words, the building envelope is a barrier between the inside and the outside of a building and includes walls, the roof, windows, doors and other components like isolation and membranes that act as a shield.
The building envelope plays a central role in protecting people inside from external influences, ensuring comfortable living conditions and thermal comfort. When we think of energy efficiency, it is essential to create an airtight seal that prevents unwanted air exchange. However, resistance to water, heat, light and noise transfer are also important and cannot be ignored.
The biggest challenge for a building envelope is withstanding its exposure to environmental stresses like water, wind, extreme temperatures, UV or other substances over a long time. Material fatigue needs to be considered as well to avoid performance losses over time.
For Saint-Gobain® Tape Solutions, the vision is to allow comfortable low or positive-energy living spaces that are easy for everyone to access. Comfort is viewed as a whole, and solutions and materials contribute to improving the quality of life and protecting people’s health. Small parts like tapes can have a significant impact on turning this vision into reality. Let’s examine some of the ways:
- Tapes used for membrane sealing can ensure the reliable connection of membrane sheets. They facilitate membrane assembly and avoid damage or punctures that could affect tightness. Foam tapes are essential for traditional and modern lightweight construction. They help decouple structures and fill gaps.
- Tapes can be utilized to seal flat roofs, windows, doors and other applications with more direct exposure to environmental stresses. Their UV, water and thermal resistant design allows lasting bonding and attachment, or to perform as reliable barriers preventing moisture ingress and protecting structures even under extreme conditions.
- Due to the increased use of glass facades as part of the building envelope in modern architecture, spacer tape and special glass bonding solutions are increasingly important. They are key components in structural silicone glazing systems, helping to maintain a uniform distance between the glazing panel and the structure. They provide a locating surface for the silicone structural sealant.
These are just a few examples of the vital role tapes play within the building envelope and within modern architecture to ensure longevity and functionality.
Foam tapes are very versatile and can add value in many ways and applications. Used between decoupled structures, they help in creating air- and watertight seals. These seals not only prevent thermal bridges, but also perform as noise and vibration dampening and absorb materials for optimized acoustic comfort.
In addition to sealing and dampening, foam tapes can be important components in fire protection. A good example of a product that combines all the essential properties into one is Norseal® FS1000. This intumescent foam is both soft and conformable. It forms a reliable seal that is fire resistant and has the ability to block smoke, air and water.
Another advantage foam tapes provide is their low VOC (Volatile Organic Compounds) for good indoor air quality and healthy environments. Especially when used in HVAC (Heating, Ventilation and Air Conditioning), fungicide properties are a big plus.
In the end, the right foam materials offer many advantages for the quality of life inside, the energy efficiency of buildings and building lifetime value.
The way we build future homes and the entire construction sector has a significant influence on people and the environment. At Saint-Gobain, we are following the purpose of “Making the world a better home” with innovative solutions for the building envelope and many other areas.
