Firestop in sandwich panels

Speed up your project with our certified solutions

Obtaining approval for firestop in sandwich panels can be frustrating, time-consuming and expensive. To help streamline the certification process and get your project off the ground quickly, Hilti has joined forces with two major European manufacturers to certify cost-efficient sandwich panel design solutions for a wide range of applications. Work with Hilti to get expert advice and support throughout the design and approval process, helping save you time, money and stress caused by delays and costly rework.

Benefits of sandwich panels

The use of sandwich panel wall systems can speed up construction cycles for large commercial and industrial projects. The light, prefabricated panels can be easily transported and quickly erected on site, allowing other trades to begin work immediately. In facilities such as data centers where every additional day of uptime counts, these fast-track construction methods can help improve and accelerate return on construction investment. However, while sandwich panels with mineral wool cores exhibit excellent performance during wall-certification fire testing, adding building service penetrations greatly impacts their fire performance and requires separate test certifications.

Passive Fire Protection

Lack of standardized testing for sandwich panels

Fire tests of sandwich panel penetrations have confirmed that these wall types perform quite differently than standard drywall or concrete wall constructions. Unfortunately, the absence of standardized test methods and the huge variety of panel systems on the market has led to an industry-wide lack of testing for these wall types. This lack of testing means owners, designers and contractors have struggled with extensive schedule delays due to time-consuming engineering judgments and strict approval processes with local authorities.

Cooperative testing

Benefit from cost-efficient design

To help make commissioning faster and more reliable, Hilti’s Firestop team has worked with Paroc Panel System and Rf-Technologies (fire dampers) to provide tested and certified solutions for a wide range of applications. Coordinating densely packed services within tight technical areas is always a challenge. However, by combining the engineering power of three leading manufacturers, we can consider the structural requirements of sandwich panels alongside the spacing limitations of these certified fire penetration solutions. For the most cost-efficient design, contact us early in the design process - especially for firestop and fire dampers: by considering the parameters of tested systems early, you can help reduce time-consuming engineering judgements as well as costly rework, construction delays or commissioning problems.
