New ROCKWOOL Red Book Released

Definitive interactive guide to acoustic, fire and thermal insulation for specifiers updated for 2021.


A 2021 version of the ROCKWOOL Red Book has now been released, capturing a series of key technical updates to ensure that this interactive guide to stone wool insulation will continue to save specifiers’ time and make it simple to identify the right product for facade, wall, floor, and roof applications.

Launched last year in an all new interactive format, the ROCKWOOL Red Book is a powerful digital tool which provides access to technical data, product certification and a wide range of specification support materials across the ROCKWOOL product range.

One of the major updates for 2021 is the inclusion of British Board of Agrément (BBA) certification for the ROCKWOOL HARDROCK® range of flat roofing products. ROCKWOOL HARDROCK® Multi-Fix (DD) and Tapered were recently certified by the BBA following rigorous testing of their durability, thermal and fire performance. This independent accreditation validates the suitability of these products in a flat roof application. Useful interactive links to this certification can now be accessed directly through the ROCKWOOL Red Book.

External Wall Insulation Dual Density Slab has been added as a new product, providing specifiers with information on its use in ETICS external wall systems. Made with ROCKWOOL dual density technology, the upper layer has a distinctly higher density which provides a robust outer surface for applying render. Thermal and acoustic performance data for this new product can be easily accessed from the ROCKWOOL Red Book, as well as relevant NBS clauses.

The timely update for the latest edition also includes updated digital links to approved documents and regulatory guidelines, as well as new content on the aged performance of stone wool.

In response to customer feedback, extended U-value data is provided for floors, and imagery and technical drawings have been updated and improved throughout the guide.
Application-driven, the ROCKWOOL Red Book provides detailed guidance for designing ROCKWOOL stone wool insulation into all types of buildings.

“Our customers tell us that the ROCKWOOL Red Book is their go-to guide to specify insulation. We’re continually improving this as a practical guide that’s easy to use and saves customers’ time. We want to ensure it remains relevant and accurate,” commented Paul Barrett, Head of Product Management at ROCKWOOL.
