THERMAL INSULATION CAVITY BATT Thermal protection for masonry cavity walls

THERMAL INSULATION CAVITY BATT THERMAL INSULATION CAVITY BATT ROCKWOOL Thermal Cavity Batts are a semi-rigid full fill insulation solution for use in external and party masonry cavity walls. The batts are quick and easy to cut, and provide a great fit, reducing installation time, avoiding gaps and cold spots, and maximising long-term performance. Water repellence stops the transfer of moisture from the outer to the inner leaf of the wall, preventing rot and mould. The batts are Euroclass A1 non-combustible.

Advantages • Non-combustible - Euroclass A1 • British Board of Agrement approved for use in all exposure zones • Water repellent • Quick and easy to install without gaps • Does not require the use of cavity barriers Description The batts provide thermal insulation for external walls as well as thermal and acoustic insulation for party walls, to meet with Part L and Part E of the Building Regulations. The batts are quick and easy to install, providing a tight fit, without gaps, to maximise performance. Water repellence means that any moisture from the external leaf will not transfer to the...

Performance Building Regulations Part L (Conservation of fuel and power) Approved Document L 2013 edition came into force on 6th April 2014 and set out performance requirements for England. Scotland and Wales now have separate requirements, also shown in the table below, which states performance standards required for extension and thermal upgrade external wall applications. Constructions to meet Building Regulations Construction 1 102mm Facing brick outer skin, ROCKWOOL Cavity full fill, 100mm internal concrete block (various densities). Internal finishes: light plaster or plasterboard on...

Construction 2 Render on 100mm medium dense block outer, ROCKWOOL Cavity full fill, 100mm internal concrete block (medium dense or Standard Aircrete). Internal finishes: light plaster or plasterboard on dab. The U-values shown in the constructions above are based on the following: • Internal face of walls lined with either plasterboard on dab or 13mm lightweight plaster • Block sizes assumed to be 440 x 215mm, mortar joints assumed to be 10mm wide • Wall ties are stainless steel with a cross-sectional area of 12.5mm2 Party wall thermal bypass - achieving a zero heat loss Building standards...

Party walls - Achieving Part E of the Building Regulations (resistance to the passage of sound) As well as delivering the required thermal performance for extensions and thermal upgrades in external cavity walls, ROCKWOOL Thermal Cavity Batt also achieves a zero U-value heat loss in party walls, and helps to achieve the required airborne sound reduction of 45dB to achieve Part E of the building regulations. Robust detail approval for use as acoustic insulation in masonry party wall constructions Robust Details Limited was formed in December 2003 in response to the housebuilding industry's...
