Separating Party Wall Insulation

ROCKWOOL party wall insulation harnesses the power of stone wool. We offer high density products, for a rigid fit in solid walls, and low density slabs easily placed in wooden or metal framed constructions. Our solutions provide all-round safety and comfort.

Key benefits:

• Fire resilient – non-combustible and able to withstand temperatures exceeding 1000°C, boosting party wall fire stop ROCKWOOL insulation retains lifetime fire performance³.
• Temperature regulating – captures natural air in between stone wool fibres helps to maintain a steady temperature, reducing cooling costs⁴.
• Acoustic performance – our party wall sound insulation improves resistance to airborne sound⁵.
• Water repellent – stone wool repels water, stopping it from penetrating the product and letting moisture pass through. This helps keep party wall spaces warm and dry⁶.
• Natural & sustainable – produced with zero waste water discharge⁷ and can be recycled repeatedly, without any quality loss⁸.

There are different approaches to installing our party wall insulation products, depending on whether you are working on a new build or a renovation.

During a new build, you can easily incorporate one of our various solutions to improve the thermal, sound and fire resistant properties of a seperation party wall.

When renovating a party wall, to inmprove its performance, a good solution would be to construct a dry wall solution against thr separation wall. Alternatively, you could have your wall inspected by an installer and a insulated with our granulate solution.

in some countries, products are available that can be placed at the rafter line or adjacent outer wall - to avoid heat loss at the edge of the construction.

Installation guides can be found on our individual product pages.

Key tips:

• Measure out space before installing – make sure you have the right amount of insulation needed for your party wall.
• Don’t leave any gaps – ensure all voids or gaps are covered, to avoid remaining heat or sound passing through cavity spaces.
• Choose the correct insulation – select your insulation based on thermal, acoustic and fire performance, to ensure optimal performance.

Our stone wool products can help reduce energy bills and nuisance noise, improving the lives of those living and working in buildings with ROCKWOOL insulation.

Stone wool insulation is:

• Healthy for the environment
• Robust and durable
• Carbon footprint-reducing

Once our products have been used, they can also be recycled – ensuring those resources aren’t wasted¹¹.
