ROCKWOOL introduces new STA Certified timber frame insulation solution

26 Aug 2019

With the market for new-build timber frame housing continuing to grow, ROCKWOOL has announced the launch of a new Timber Frame Slab insulation range.

This new stone wool range is specifically designed to help developers take advantage of the many performance characteristics associated with ROCKWOOL non-combustible insulation alongside a quick-to-install, durable and sustainable solution that’s perfect for off-site and on-site timber frame construction.

James Mills, Product Manager at ROCKWOOL explains: “The new Timber Frame Slab range from ROCKWOOL is an easy to fit, long-lasting insulation range that delivers high performance thermal and sound insulation for homes. It’s also non-combustible, water repellent and vapour permeable, making it the perfect choice for fast, predictable and reliable timber-frame projects.”

According to the Structural Timber Frame Association (STA), testing has shown that different insulation types can significantly impact the spread of fire, including stopping or slowing it down, undergoing chemical changes, and even adding fuel to a fire and losing volume and creative voids for fire to spread.

From full-scale tests three categories have been established; Type FI Build 1 – Melts under heat and has combustible gases, Type FI Build 2 – Shrinks under heat and may have combustible gases and finally Type FI build 3 – Maintains volume and does not combust. ROCKWOOL stone wool insulation is the only insulation type to achieve Type FI build 3. The STA goes on to provide design guidance to significantly reduce separating distances by using fire-resistant materials and constructions including ROCKWOOL insulation and Norbord OSB.

ROCKWOOL Timber Frame Slab is designed as safe, fast and high-quality external wall insulation. The range offers enhanced thermal performance of 0.034 w/mK at an installation optimal density, which can meet and exceed the requirements (thermal) of Part L of the Building Regulations. ROCKWOOL Timber Frame Slab is an engineered density product designed to provide a tight friction fit which speeds installation and minimises waste.

Available in 570mm widths it will friction fit into standard 600mm centres frames with no gaps, without the need for cutting. As ROCKWOOL Timber Frame Slab is manufactured from stone, any waste can be collected and recycled by ROCKWOOL to off-set the cost of landfill and help builders enhance their sustainability credentials.

ROCKWOOL insulation is a Euroclass A1 Fire Rated (non-combustible) product, it does not burn, makes no contribution to fire growth and presents no smoke hazard. This fire resilience helps enhance building safety both during the more vulnerable construction stage, and when the property is -built and occupied. It can also allow housebuilders to reduce separating distances between properties on a development to maximise space utilisation on a site.

With its dense, non-directional fibre structure, ROCKWOOL’s Timber Frame Slab will provide excellent sound insulation performance. It effectively traps sound waves and dampens vibration, reducing external noise and acoustic intrusion from between rooms within the same property.

Once installed, ROCKWOOL Timber Frame Slab, will hold its shape, ensuring that the insulation always performs to specification for the lifetime of the home. This product range is also lightweight, making it more efficient to transport and easier to handle on-site.

In addition, the range is both water repellent and vapour permeable to help properties to breathe and counter moisture uptake issues, ultimately reducing the risk of condensation and mould.
