Building Compartmentation Specialists

Compartmentation is a critical aspect of fire safety design. Our team conducts compartmentation surveys for residential and commercial properties to prevent the spread of smoke and fire. We scrutinise varying structural elements, including walls, roof voids and cavity barriers, and apply fire-resistant materials to rectify any instances of non-compliance.

Fully-Compliant Penetration Sealing Systems

Major construction projects utilise a wide range of third-party specialists for the provision of basic services such as electricity, plumbing and broadband. For these services to be installed, teams will create service penetrations in walls, floors and ceiling voids. This will often involve the passage of wires, pipes and ventilation ducts through compartment walls or floors.

It is critical that any gaps or openings caused by service penetrations are protected using an acrylic sealant. Otherwise, the smallest amount of air leakage can facilitate the passage of smoke and jeopardise the compartmentation system. Our team implements quality penetration sealing systems, helping to contain the spread of fire for enhanced building safety and risk management.

Fire Protection Compliance Surveys

We are regularly hired by leading construction companies to carry out professional fire risk surveys. Our team operates with high standards of professionalism, with the ability to quickly identify non-compliant installations and make specialist fire protection recommendations.

We play a vital role in improving standards across the fire protection industry. Clive Miles, our founder and CEO, belongs to the Association for Specialist Fire Protection (ASFP). We are also accredited by FIRAS, a certification body that is highly regarded in the passive fire protection and firestopping industry. Finally, we offer Continued Professional Development (CPD) to project managers, building owners and site teams, helping us spread knowledge on passive fire protection best practice.

Expert Project Management and Procurement

At CLM Fireproofing, we pride ourselves on not only our technical expertise but our ability to manage major commercial projects. We look to engage clients as early in the project timeline as possible, helping us to cater to their unique needs. This allows us to suggest appropriate timescales, select quality products and ultimately deliver market-leading passive fire protection systems on time and within budget.
