The Ultimate Solution for Insulating Pitched Roofs at Rafter Level
A new product from Knauf Insulation is changing the way
we insulate rooms in the roof. Room-in-Roof Roll ensures easy and
quick installation as well as excellent thermal performance.
The product recently forced a change of specification on a
residential development at a prestigious location in
Chester.
Springfield Residential Development Company
produced a brief which aimed to ‘create a landmark house,
with a range of features to attract a discerning homebuyer.’
The developers were aware of the increasing need for economic,
sustainable housing and every element of the construction was
considered with this in mind.
Room-in-Roof Roll is a glass mineral wool roll
with an integrated, overlapping foil faced layer, which is
manufactured using recycled bottles and is classified as Zero ODP
and Zero GWP. The product therefore contributed positively to the
project’s aims, particularly with respect to its contribution to
the total number of credits that would be awarded under the Code
for Sustainable Homes.
Insulating pitched roofs has long been an
intricate and complex job, however the problem was intensified in
Chester because of the unusual nature of the roof. Access was only
possible from scaffolding as the roof was located above an open
plan galleried entrance hall.
The exposed design meant that a durable
insulation with excellent thermal performance was key. For
optimised thermal efficiency it was essential that there were no
air gaps left between the insulation and the rafters.
Room-in-Roof Roll is designed to ‘friction fit’ between the
rafters, ensuring all spaces are filled, eliminating heat loss via
air gaps (which are commonly associated with rigid foam boards in
this application) and thereby maximising the thermal performance of
the roof.
Stuart Brown of Springfield Residential
Development Company commented, “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.”
