External fire boards from Aestuver offer top-tier weather resistance for outdoor use. Freeze-thaw proof, water-resistant, Type X certified—ideal for exposed steel beams, tunnels, and buildings with lasting fire protection.

Cement fire boards from Aestuver range excel as the top fire protection solutions. Offering 2-hour fire rated cement board performance, superior durability, and proven fire resistance for tunnels and buildings.

Fire resistant service enclosures provide an unmatched solution for fire protection of electrical and mechanical installations. Electrical cables and services which don’t have sufficient fire protection will fail in case of fire and won’t maintain their circuit integrity for life safety and fire-fighting purposes. Numerous electrical cables are required to function during fire evacuations to ease the escape of people by activating emergency signage, signals or smoke extraction systems.

Fire protection systems for tunnels must withstand not only the threat of intense fires - often fueled by hydrocarbons from vehicle accidents - but also harsh climatic conditions like high humidity, temperature fluctuations, water ingress, and chemical exposure from exhaust fumes and road salts.

This guide provides a comprehensive overview of the installation process for Aestuver tunnel fire protection system focusing on best practices, essential tools, and key considerations. Whether you're a seasoned professional or new to the field, this article will equip you with the knowledge needed to effectively install these vital systems. At this point we assume that you already selected a suitable Aestuver fire board based on the project specifications and tunnel fire curve.

Concrete fire protection is a topic that is often discussed in relation to upgrades of existing structures. The rise in interest for concrete fireproofing may be caused by a new regulation or change of building purpose or simple by degradation of concrete beams, columns or slabs.

Time-temperature fire curves are commonly used in tunnel fire protection. Fire safety in tunnels is a critical aspect of civil engineering and fire engineering. Tunnels, whether for road or rail present unique challenges due to their confined nature and the potential for high heat and smoke accumulation. One of the key tools in designing effective fire protection systems for tunnels is the time-temperature fire curve. This article will delve into the importance of these design fire curves, their types, and their application in tunnel fire protection.

Aestuver fire protection panels stand out as the premier choice when it comes to ensuring the highest level of safety and durability in tunnel and building construction. The material itself was manufactured for the first time already in 1981. Due to continuous development and unique product composition, there are numerous projects worldwide with fire protection systems using Aestuver boards. In this short summary we would like to present why Aestuver fire protection boards are the optimal solution for your fire protection needs.

Concrete spalling is a critical issue in tunnel fires, posing significant risks to structural integrity and safety. It's essential to understand the mechanisms behind spalling, the chemical transformations involved, and the measures to mitigate its effects. This article delves into the processes and temperature ranges at which these transformations occur.

Tunnel fire protection is often unjustly criticised for its costs. However, such an opinion without solid numbers can be completely misleading. A few years ago the Aestuver team together with STUVA carried out possibility study that dived into the details of costs of tunnel fire protection. This study not only shows the costs of installing these fire barriers but also highlights the benefits. For example, using fireproof boards in a tunnel can be a cost-effective solution.
