NatureWall Internal Wall Insulation

NatureWall - A safe, simple, effective internal wall insulation system combining the capabilities of natural wood fibre insulation with the speed of modern methods.

The NatureWall internal wall insulation system uses natural wood fibre insulation to provide unrivalled insulation, moisture control and heat retention. Wood fibre insulation, well known for its breathable properties, is ideal for use on solid-walled stone and brick properties as well as more modern brick or block cavity walls.

To provide very high levels of airtightness and to improve suitability over a much greater range of properties, we have included and airtightness membrane within the system. This gives us a range of membranes to choose from to ensure the correct functioning of the system in every individual project.

A battened service zone is included with the system to allow services to run through the walls without breaking through the airtightness layer. Even in commercial spaces, it is easy to get high levels of insulation without impacting practicality.

NatureWall can be finished with either standard plasterboard or Fermacell, depending on the level of robustness required. Both are highly breathable and low embodied energy products, complimenting the low carbon nature of the system. With this simplicity, a wide range of tradespeople can use the system with their existing skills.

Using the latest Heat and Moisture Modelling software (WUFI), we ensure that the correct amount of insulation is used on each project. This avoids issues such as building damage, moisture issues and mould growth that arise from a 'one-size-fits-all' approach. The NatureWall Suitability Confirmation (NSC) document lists all of the materials required for each project so installers know what is necessary.

Naturewall has been fire tested by Warrington Fire and confirmed as having a rating of B-s1,d0, well within what is required by the UK Building Regulations. The system is in the process of acquiring a third-party KIWA BDA Agrement certificate to confirm its suitability and its compatibility with PAS2030/2035.

How much does NatureWall reduce energy costs?

Even the thinnest layers of the NatureWall system will reduce conductive heat loss through uninsulated walls by more than 65%, dramatically improving comfort and indoor air quality, with the thicker layers reducing heat loss by up to 85% or more.

Exactly how much this will reduce your energy bills by depends on how you heat your building but the typical payback period would be between 5 and 10 years, depending on whether you use gas or electricity to supply your heat.

Because of the way the system is detailed around openings and penetrations, it also makes your walls much more airtight, again reducing your heat loss and saving on energy costs.

Assessing, designing and installing NatureWall IWI

To ensure designers and installers know exactly how to assess the project, design the system in and install it correctly, we have created a NatureWall Installation Course on our free, online training platform. Fibres Academy runs through the procedures and tests course participants knowledge to make sure they understand what is required.

Having an online training resource allows access to all the necessary design and installation guidance, whether at home or on site, enabling users to learn and up-skill whenever and from wherever it suits them.
