Stud wall Insulation
Stud walls are commonly used to partition rooms or add internal insulation to a property. They’re a great method of creating a flexible, liveable building that works how you want it to. However, if you install a stud wall, it’s vital that you consider how to insulate it properly. STEICO insulation between studs in a timber stud wall offers a range of benefits, including thermal and acoustic insulation in a single layer.
What is stud wall insulation and how does it work?
Stud wall insulation is installed between the joists of a stud wall. The two main types of stud wall insulation are:
- Flexible batt insulation
- Air-injected insulation
Without insulation, heat and noise can travel through that space and negatively affect your building. That’s true whether you are building a partition or are using a stud wall as a frame for interior wall insulation. The solution is to install stud wall insulation as part of the internal stud wall system.
When specified and installed correctly, it can help make your home more energy efficient, contributing to improved acoustic performance.
What are the important considerations when installing stud wall installation?
To get the most out of your stud wall insulation, it needs to be specified correctly for your system. Some key considerations include:
- Thickness and performance – The required thickness of your stud wall will depend on its application. If the stud wall is being used for internal wall insulation, it must achieve a u-value of at least 0.7 W/m2K in line with Part L of the Building Regulations.
- Acoustics – Your chosen insulation must provide acoustic performance in line with Part E of the Building Regulations.
- Extras – Do you need to install an additional vapour control barrier with your insulation to complete the stud wall?
What are the features and benefits of STEICO stud wall insulation products?
STEICO offers stud wall insulation products to suit both partition stud walls and interior wall insulation projects. Firstly, flexible wood fibre insulation like STEICOflex:
- Bulk density of 50kg per cubic metre.
- Can help you meet your required acoustic rating,
- Diffusion-open wood fibre allows moisture to be absorbed, distributed and quickly dried through evaporation, reducing the risk of condensation, mould, and potential structural and health risks associated with excess moisture.
- Binds 82kg CO2eq during Life Cycle Stage A1 as defined in EN 15804+A2.
- Responsibly sourced from PEFC accredited timber (PEFC/04-31-2550).
- Can help to regulate internal air quality and independently tested and approved by the German Institute of Building Biology in Rosenheim.
Secondly, STEICOzell air-injected insulation:
- Binds 71kg CO2eq during Life Cycle Stage A1 as defined in EN 15804+A2.
- Low density due to three-dimensional interlocking of the wood fibres.
- Diffusion-open wood fibre allows moisture to be absorbed, distributed and quickly dried through evaporation, reducing the risk of condensation, mould, and potential structural and health risks associated with excess moisture.
- Responsibly sourced from PEFC accredited timber
- Can help to regulate internal air quality and independently tested and approved by the German Institute of Building Biology in Rosenheim.
