Build with Confidence: The Importance of BBA-Certified Cavity Closers

Date Posted: 09th April 2025

Ensuring the quality and reliability of building materials is critical for safety, efficiency, and long-term durability in construction projects. A product where such assurance is vital is cavity closers.

These components play a crucial role in preventing thermal bridging, improving fire resistance, and maintaining the structural integrity of a building, so guaranteeing their performance is essential.

That’s why BBA certification matters.

Certification from the British Board of Agrément (BBA) is an assurance of excellence for the product in question. BBA certification is a testament to the quality, performance, and compliance. It is a mark of excellence that demonstrates a product has undergone thorough testing, assessment, and ongoing surveillance. For cavity closers, this means they have been rigorously examined for their thermal performance, fire resistance, and overall durability in real-world conditions – giving you peace of mind and your customers a superior build.

The key factors assessed for BBA certification are:

  • Mechanical resistance and stability
  • Safety in case of fire
  • Hygiene, health and the environment
  • Safety and accessibility in use
  • Protection against noise
  • Energy economy and heat retention
  • Sustainable use of natural resources
  • Durability

The testing process from BBA ensures the products are certified as fit for their intended use provided they are installed, used and maintained as set out in the Agrément certificate. The following cavity closers available from Timloc Building Products are all BBA certified:

  • Thermo-loc Platinum Multi
  • Thermo-loc Platinum+
  • Thermo-loc Platinum+ FX
  • Thermo-loc FR30
  • Thermo-loc FR60
  • Thermo-loc FR60+

The construction industry is constantly evolving, with stricter regulations and higher expectations for safety and performance. Using BBA-certified cavity closers provides assurance that products meet these high standards. Without proper testing, subpar products can lead to various issues including increased energy loss, fire safety risks and structural failures.

When selecting cavity closers, it is vital to prioritise products that have been independently tested and certified; investing in certified products is an investment in quality, sustainability, and peace of mind. By choosing Timloc Building Products’ BBA-certified cavity closers, you can be confident in the knowledge that the products contribute to safe, energy-efficient, and long-lasting buildings.
