With ‘Go Green’ having been the buzzword for over a decade, there is a huge demand for reducing energy expenses in the housing sector. To this end, one of the most effective methods is to deploy air insulation technology for sealing the building from the effects of external temperature. Insulated cavity closer technology, introduced in the 19^th century in the UK, is a great way to enhance the insulation properties of a building. It provides better control on the temperature inside the building by reducing the loss of heat through the convection properties of walls. With low installation cost and high returns, cavity closers are used extensively in the construction sector across the UK.

Air Tightness Through Cavity Closers

Air tightness is one of the essential factors that call for the installation of a perfect-fit cavity closer. Cavities around the doors and walls allow air to escape. This drastically affects the insulation process in the interior of the building. Even if the walls have excellent insulating properties, air cavities can hamper the insulation process. Thus, it is essential to effectively fill the cavities around the doors and walls in the building.

When it comes to filling cavities in a building, one can choose different approaches. One approach is to save on the building cost and use bricks or blocks to fill the cavities. However, the low insulating properties of bricks and blocks will not benefit the building immensely. Another approach is to use cavity closers made of high-insulating materials, such as Unplasticized Polyvinyl Chloride (PVC-U). This will help to attain better control over the temperature inside the building. PVC-U cavity fillers are also easy to install and are highly durable.

How to Choose a Cavity Closer?

Choosing a cavity closer that fits your requirements while acting as a supporting building structure is a daunting task. Here are the essential considerations to keep in mind while choosing a cavity closer:

• Flexibility: It should be flexible enough to seal cavities around doors and windows in a perfect shape.
• Insulation: It should improve the insulation of the building for enhanced thermal performance and eliminate the entrance of draughts. Look for the R-value of the material used for manufacturing the cavity closer. R-value is the measure of thermal insulation for components used in building construction. The higher the R-value for a material, the better the insulation it offers.
• Easy-to-use: Buy a cavity closer that is easy to modify as per your requirements. It should have cuts and slots to fit into the cavity with ease without causing any harm to the walls of the building.
• Durability: An insulated cavity closer should be able to withstand rough conditions of the construction site.
• Spacing: It should provide accurate space and a rigid surface to continue the bricklaying process without the need to use dummy formers.
• Customization: High on customization, it should support a large number of fitting options.
• Building standards: Make sure that the cavity closing product is manufactured in accordance with the local housing standards and building regulations.

Fill the building cavity the green way by using products manufactured from recycled materials. Cavity closers, manufactured from 100% recycled PVC-U, are available in the market. They help to curtail the construction budget while promising an eco-friendly building procedure. Virgin PVC products release a huge volume of hazardous chemicals in the manufacturing process. Thus, recycled PVC is an environment-friendly alternate to virgin PVC.
