Insulating a Pitched Roof Below & Between Rafters
Insulating a pitched roof between and below the rafters is a very common roof insulation choice, particularly for retrofit and refurbishment projects.
This method of installing roof insulation allows you to maximise the headroom by using a thinner layer of insulation beneath the rafters, whilst achieving U-Values which will ensure you comply with Building Regulations and have a roof space or loft which is comfortable for its occupants.
The recommended roof insulation for this method of warm roof construction is shown below in the possible solutions.
Ventilated Cavity & Non-Breathable Membrane
Un-ventilated Cavity & Breathable Membrane
Our internal pitched roof insulation solution is a quick and efficient method of insulating your pitched roof project.
Installing a layer of SuperQuilt internally removes the need for a vapour control layer, increases the overall thermal efficiency of the pitched roof 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 rafters.
Alternatively, multiple layers of SuperQuilt can be used to achieve your desired U-Value.
Using SuperQuilt can significantly reduce the overall impact to head height, 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).

Our 2 layer internal pitched roof insulation solution is a quick and efficient method of insulating your pitched roof.
Two Layers Of SuperQuilt Under Un-ventilated Rafters
Properties with smaller rafter depth can be an issue when specifying traditional insulation like PIR & Mineral wool due to the high thickness of insulation required.
Recessing a layer of SuperQuilt between the rafters and a layer of SuperQuilt internally removes the need for a vapour control layer, increases the overall thermal efficiency of the pitched roof and increases the internal space available due to its ultra-thin profile.
SuperQuilt can be used on its own or in conjunction with an insulated plasterboard, giving you a hassle free installation, saving you valuable money, time and space.
For projects with larger rafters, traditional insulation like PIR and mineral Wool can be used between rafters, removing the need for an insulated plasterboard.
Once SuperQuilt has been taped and sealed on all overlaps and perimeter, it also works as a high performing VCL (vapour control layer).
BreatherQuilt Over Rafters
Our over rafter insulation solution is perfect for any type of application where there is access over and between the rafters.
BreatherQuilt removes the need for a separate breather membrane as it built into the product.
Using our draped installation detail keeps the overall roof profile height down to a minimum, by allowing the BreatherQuilt to expand between the rafters.
BreatherQuilt can be used on its own or in conjunction with traditional insulation like PIR or Mineral Wool between the rafters.
BreatherQuilt gives you a hassle free installation, saving you valuable money, time and space.
The low vapour resistance of BreatherQuilt allows the rafters to breath and its W1 rating keeps the external elements out.
