Multifoil Insulation 

For Timber Frame Walls

Timber frame homes, extensions, loft/barn conversions, dormers and many more constructions are becoming increasingly more and more popular with end users, construction companies and developers for both residential and commercial properties. Timber frame boasts quality in off-site and on-site fabrication and speed of assembly on site, all whilst reducing the on-site build costs and time.

INSULATING A TIMBER FRAME WALL INTERNALLY WITH MULTIFOIL

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

SuperQuiltSuperQuilt

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.

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.

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, which can be used to achieve your desired U-Value.

Using SuperQuilt can significantly reduce the overall depth of your timber frame, when compared to traditional insulation solutions, saving you valuable money, time and space.

INSULATING A TIMBER FRAME WALL EXTERNALLY WITH MULTIFOIL

Insulating a timber frame from the external side is a lesser widely used method of insulation, this is due to the requirement for a breathable membrane in this location. Standard breathable membrane does not offer thermal performance, however they do allow the timber frame to breath.

Our patented 2 in 1 reflective foil insulation and venting membrane (BreatherFoil) is changing this and is quickly becoming the timber frame external insulation method of choice.

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 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.

Our external solution is perfect for applications where there is access to the external side of the timber frame.

Installing a single layer of Breather-Foil externally removes the need for a standard breathable membrane, increases the overall thermal efficiency of the timber frame and increases the internal space available due to its ultra-thin profile and reduction in timber frame depth.

Breather-Foils unique venting design enables the timber frame to breath meeting building regulation requirements.

BreatherFoil can be used in conjunction with traditional insulation (between the timber frame) or on its own.

Alternatively avoid the use of traditional insulation all together by using BreatherFoil & SuperQuilt, which can be used to achieve your desired U-Value.

This solution is suitable for dormer cheeks / dormer walls.

INSULATING A TIMER FRAME WALL EXTERNALLY & INTERNALLY.

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.

SuperQuilt, BreatherFoilSuperQuilt, BreatherFoil

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.

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.
