External & Internal Timber Frame Insulation Solutions

INSULATING A TIMBER FRAME FROM THE EXTERNAL AND INTERNAL.

Insulating a timber frame from the external and internal side is an effective method of insulation, particularly for loft conversion (dormer cheeks), extensions and new build projects.

This method of installing timber frame insulation offers a complete reflective foil insulation solution, allowing you to significantly reduce the overall depth of the timber frame, maximise the internal floor footprint and reduces 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.

BreatherFoil External And SuperQuilt Internal Of Timber Frame

Our external and internal solution is perfect for new build applications or refurbishments and conversions where there is access to the external and internal side of the timber frame.

Installing a single layer of BreatherFoil externally and SuperQuilt internally removes the need for a standard breathable membrane and vapour control layer, increasing the overall thermal efficiency of the timber frame and internal space available due to their ultra-thin profiles.

Both products can be used in conjunction with traditional insulation (between the timber frame), alternatively avoid the use of traditional insulation all together by using Multiple layers of SuperQuilt , which can be used to achieve your desired U-Value, for more information speak to our technical support team on 01909 726 025

Using BreatherFoil and SuperQuilt together can significantly reduce the overall depth of your timber frame, when compared to traditional insulation solutions, 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.
