“It was difficult in the past to get
the perfect finish with rigid foam boards; generally two layers
would be needed and as well as being time consuming to cut it’s
also very difficult not to leave air gaps between the rigid foam
boards and the rafters. As Room-in-Roof Roll friction fits into place and
only requires one layer, it was installed 4 times quicker than
rigid foam boards and has provided a better solution for the
homeowner. From now on Room-in-Roof Roll will always be our first
choice.”

CHALLENGE
Insulating pitched roofs at rafter level has long been an
intricate and complex job and the private developers on this
project in Chester were looking for a solution which was not only
cost-effective but more importantly easy and quick to install.
The installation procedure would be a difficult one due to the
unusual nature of the roof. Access would be from scaffolding as the
roof was located above an open plan galleried entrance hall.
As well as simplifying the installation, the insulation would
need to provide reliable long term performance – this requirement
being intensified by the exposure of the roof to the main living
space.
SOLUTION
Knauf Insulation proposed 200mm Room-in-Roof
Roll 37 as a cost-effective and easily installed method of
achieving the project requirements.
Room-in-Roof Roll is a brand new foilfaced
glass mineral wool roll which is far more cost-effective than
traditional rigid foam board solutions as well as being inherently
sustainable as it is manufactured using a high content of recycled
glass bottles.
The integrated foil facing acts as a built in vapour control
layer and the overlapping facing is quickly stapled into place
while friction fitting reduces the need for time consuming cutting
and fitting commonly associated with the installation of rigid foam
boards.
The developers commented that the product was actually 3-4 times
quicker to install than rigid foam boards.
Friction fitting of the product allows the rafter space to be
completely filled, eliminating heat loss via air gaps and thereby
maximising the thermal and acoustic performance of the roof. As a
comparison rigid foam boards are susceptible to air gaps which are
often hidden by covering with foil tape or partially filling with
expanding foam.
Thanks to its speed of installation, costeffectiveness and
thermal efficiency, Room-in-Roof Roll is set to become the
ultimate solution for insulating pitched roofs at rafter level.
