SOUND INSULATION SLAB Acoustic insulation for internal walls and floors

SOUND INSULATION SLAB SOUND INSULATION SLAB ROCKWOOL Sound Slab is used to create quiet, peaceful and comfortable spaces in both residential and commercial environments. Being made from stone, ROCKWOOL insulation absorbs sound waves and reduces vibration due to its density, a non-directional fibre orientation and an open porous structure; trapping and preventing sound waves from traveling through it. ROCKWOOL insulation is also non-combustible, able to withstand temperatures in excess of 1000°C.

SOUND INSULATION SLAB Provides noise reduction - Quiet Mark™ approved Non-combustible stone wool with a Euroclass A1 fire rating Water repellent and vapour permeable resists rot and mould Patented FLEXI Edge® for friction fitting ROCKWOOL Sound Insulation Slab has been designed for use in internal and separating walls and floors, reducing noise from adjacent properties, and from other rooms within the same dwelling. Quick and easy to install, no gaps and minimal waste Dimensionally stable and durable, maintaining performance over time Produced from sustainable, renewable volcanic rock Noise...

SOUND INSULATION SLAB Performance Building regulations – Acoustics: Approved document E Approved document E (resistance to the passage of sound) was introduced to the Building Regulations in 2003 and sets out acoustic performance for new build residential housing, schools and other construction types. Part E also brought about pre-completion testing. For new buildings, the separating wall build-ups in this section comply with Robust Details, which avoids precompletion testing, each of these systems carries a robust detail reference. Overview of requirements The diagram below summarises the...

SOUND INSULATION SLAB Protection against sound within a dwelling-house (England & Wales Only) Internal walls between a bedroom and other rooms, as well as internal floors, should be designed and constructed to provide a reasonable resistance to sound. The minimum required performance standards are given in terms of laboratory values. Pre-completion site testing is not required. Note that this requirement does not apply to: 1. Internal walls that contain a door 2. Internal walls that separate an en-suite from the associated bedroom 3. Existing walls and floors in a material change of use....

SOUND INSULATION SLAB Installation ROCKWOOL Sound Slab applications This guide gives an overview of the key constructions for domestic sound proofing. Where appropriate, references for robust details are included, and system performance will meet or exceed those of the building regulations listed above.

SOUND INSULATION SLAB Party Wall Thermal Bypass achieving zero U-value heat loss Approved Documents L1A & L2A of England and Wales’s Building standards recognise that where party cavity walls between connected buildings are untreated, considerable heat can escape through them. A key feature of the SAP calculation is that party wall cavities should have a zero heat loss (U-value 0.0W/m2K). If these cavities are left unfilled and unsealed, a U-value of 0.5W/m2K will automatically be applied making it extremely difficult to meet the TER compliance. The following table shows the different...
