Internal Timber Frame Insulation Solutions

INSULATING A TIMBER FRAME FROM THE INTERNAL.
Insulating a timber frame from the internal side is the most common method of insulation, particularly for retrofit, refurbishment, conversion, and new build projects.
This method of installing timber frame insulation allows you to significantly reduce the overall depth of the timber stud, maximise the internal floor footprint and reducing the overall cost of the timber frame. Using our highly reflective, thin profile insulation offers great benefits, whilst achieving U-Values which will ensure you comply with Building Regulations and have a space which is comfortable for its occupants.
The recommended insulation for this method of construction is shown below.
SuperQuilt Internal Side Of Timber Frame


Our internal timber frame solution is a quick and efficient method of insulating your new build or existing timber frame project.
Installing a layer of SuperQuilt internally removes the need for a vapour control layer, increases the overall thermal efficiency of the timber frame and increases the internal space available due to its ultra-thin profile.
SuperQuilt can be used on its own or with traditional insulation such as PIR or mineral wool between the timber stud.
Alternatively, multiple layers of SuperQuilt can be used to achieve your desired U-Value, for more information speak to our technical support team on 01909 726 025
Using SuperQuilt can significantly reduce the overall depth of your timber frame, when compared to traditional insulation solution, saving you valuable money, time and space.
Once SuperQuilt has been taped and sealed on all overlaps and perimeter, it also works as a high performing VCL (vapour control layer).
This solution is suitable for dormer cheeks / dormer walls.

SuperQuilt Internal Side of a Dwarf Wall (Loft Conversion)


Our internal dwarf wall solution is a quick and efficient method of insulating your vertical timber stud section (that connect your rafters to your floor joists) when carrying out a loft conversion.
Installing a layer of SuperQuilt internally removes the need for a vapour control layer, increases the overall thermal efficiency of the timber frame and increases the internal space available due to its ultra-thin profile.
