Frequently Asked Questions
What are Rockwool Flexi 50mm acoustic insulation slabs used for?
Rockwool Flexi 50mm slabs are designed for acoustic and thermal insulation in timber and metal stud walls, separating floors and pitched roofs. They help reduce sound transmission between rooms and improve overall energy efficiency.
What is the “flexi edge” on Rockwool Flexi slabs?
Each Rockwool Flexi slab has a flexible edge on one side that gently compresses as it is fitted between studs or joists. This ensures a tight friction fit with minimal gaps, improving acoustic and thermal performance and making installation easier.
Can Rockwool Flexi 50mm be used in both timber and metal stud partitions?
Yes. Rockwool Flexi is suitable for use in both timber and metal stud wall systems, as well as in intermediate floors and some roof applications. Always check the system details and follow Rockwool installation guidance for the application you are working on.
Is Rockwool Flexi acoustic insulation fire resistant?
Rockwool stone wool insulation is non-combustible and contributes to fire resistance in tested wall and floor constructions. The overall fire performance depends on the complete system build-up. Always consult Rockwool fire performance data and relevant building regulations.
Does Rockwool Flexi provide thermal as well as acoustic insulation?
Yes. While often specified for its excellent acoustic properties, Rockwool Flexi also provides effective thermal insulation. It helps reduce heat loss through stud walls, floors and roof structures when used as part of a compliant build-up.
How do I cut Rockwool Flexi 50mm slabs to size?
Rockwool Flexi can be cut using a sharp insulation knife or a fine-toothed saw. Mark the required width, cut on a firm surface and wear appropriate personal protective equipment such as gloves, long sleeves, eye protection and a suitable dust mask.
Are Rockwool Flexi slabs resistant to moisture and mould?
Rockwool stone wool does not support the growth of mould or fungi and is dimensionally stable. However, it should be kept dry during storage and installation, and the building envelope should be detailed to prevent ongoing water ingress.
Do Rockwool Flexi slabs need to be mechanically fixed?
In many stud wall and floor applications, the friction fit created by the flexi edge holds the slabs firmly in place without additional fixings. Follow the recommended installation method for your particular wall, floor or roof system.
Can Rockwool Flexi be used in ceilings and roof slopes?
Yes. Rockwool Flexi can be used between rafters and ceiling joists in some pitched roof and ceiling applications, provided there is suitable ventilation and an appropriate vapour control layer where required. Always follow Rockwool roof build-up guidance.
Is Rockwool Flexi 50mm suitable for DIY installation?
Rockwool Flexi slabs are straightforward to cut and friction fit, making them suitable for competent DIYers as well as professionals. Always read the installation instructions, wear appropriate PPE and follow good site safety practice.
