Cavity Closure using Sustainable Building Materials in House Construction

The Cavalok product range is the ideal green product. Not only are the cavity closer products made from sustainable building materials but also the product itself saves household energy by improving the building fabric. The products, along with their accessories, are designed to improve thermal performance and the building process of door and window openings in house construction.

Cavalok Building Products is committed to recycling huge amounts of waste PVC in its manufacturing process, its products provide a valuable means of re-using plastic waste and continues to strive for the highest standards in environmental performance.

Waste, post-consumer PVC is taken from across the country, cleaned, reprocessed and extruded into market leading cavity closer frames.

Cavalok has always showcased an enviable product range, coupled with fine quality accessories, as the world's sole manufacturer of BBA-approved cavity closer systems that are made from 100 percent post-consumer recycled PVC-u. Further, Cavalok products adhere to the Building Regulations requirements and go further in meeting Accredited Details and compliance with the Code for Sustainable Homes.

Cavalok offers a core range of products that assist house construction and commercial construction. Cavalok also introduced the Big Blok system for wide cavity walls to demonstrate the company's positive response to regulatory changes proposed by the Code for Sustainable Homes.

The Code pushed forward to set targets to improve energy efficiency in new structures spanning a period of ten years. Builders who chose to use products that are sustainable and energy efficient were to be rewarded with credits. In this context, Cavalok emerged as the first and only sustainable cavity closer to offer 100% post consumer recycle materials, constituting a 'responsibly sourced' sustainable building material.

As more stringent eco requirements were formulated, building designers sensed the need to have wider cavities that offer more insulation and deliver better U-values. To address this need, the Big Blok cavity closer was designed. Today, the Cavalok product range features Big Blok cavity closers for 125mm, 150mm and other large cavities. Incremental cavity sizes can be produced to special order. The 300mm Big Blok system has helped achieve Code Level 6 zero carbon requirements. This means that Big Blok system suits all code levels.

Significantly, the use of insulation on all Cavalok cavity closure comes with zero reading of Ozone Depletion Potential. Further, the Global Warming Potential of Cavalok cavity closures are below five. No wonder, architects, contractors, housing developers and engineers believe that using a Cavalok cavity closer enhances a building's energy efficiency and sustainability.
