Joint sealing is a necessary and often under-appreciated process in construction. Joint sealing prevents the passage of air, smoke, and water through cracks and spaces. It also provides thermal and sound insulation. Although not the most prominent part of construction, joint sealing provides essential benefits to any construction project. There are numerous applications related to joint sealing, with some of them stated below.
Joint sealing is essential to achieving low energy usage. Without it, air movement wouldn't be restricted, resulting in heat loss in the winters and cold air in the summers. It would require additional heating and cooling measures, in order to achieve the same temperatures and result in higher cost.
Roof joints – Joint sealing on roofs is absolutely essential between flashings and around skylights in order to prevent air movement and water leaking into the structure.
Floor joints – Joint sealants on floor joints help protect the flooring against the wear and tear of abrasive cleaning chemicals, high pedestrian traffic and heavy machines such as floor cleaners or forklifts.
Facade joints –Facade joints are designed to allow for movement of the fašade. They require joint sealing for good adhesion and for energy saving. These joints are also subject to harsh weather conditions, from which joint sealing can help protect them.
Interior joints – There are different types of interior joints, each requiring different types of sealants.
Window and door installation and insulation – In these areas sealing is especially important as they are pathways for air circulation between the building and the outside. The lack of proper sealing in these areas can lead to large energy losses
Natural Stone silicone
Concrete joint sealant
Parking Lot Grade sealant
Loop Detector sealant
Ceramic silicone is a watertight sealant used in joint areas often exposed to water
Natural Stone silicone is a sealant that allows for movement in expansion joints and is strong enough to support glass, plastic and metal that is often exposed to strong winds
Urethane sealant is designed to seal concrete in sidewalks, balconies and factories etc.
Concrete joint sealant is used to seal cracks in concrete
Parking Lot Grade Sealant is commonly used for parking lots, slow traffic and pedestrian areas
Loop Detector sealant was designed for use in traffic detection devices.
Different applications require sealants of varying viscosity and chemical makeup, in order to withstand the conditions that they will be subjected to. Many sealants are available in a variety of colours to complement, rather than stand out in the area in which they are used.
In addition, joint sealing products are also used for colour and stain protection on floor tile.
Even in areas not related to energy loss joint sealing can be highly important. Having a well-sealed building not only prevents potential water damage, but also reduces unwanted visitors such as spiders, beetles and snakes that like to sneak in through cracks and joints in the outside walls
Just like paint and carpet, joint sealant ages and needs to be repaired or replaced over time, resulting in poor air and sound control. If your home is in need of better air and sound control, consider repairing and replacing your sealants instead of going for more drastic measures right away. Even one or two doors or windows with ineffective sealing can have a dramatic impact on your energy costs.
