CHALLENGE
First opened in 1957, the prefab house that was previously home
to the Ide Hill Scout Group was no longer big enough for the
expanding group’s needs. Urgently requiring new premises, Ian
Courtneidge, Chairman of the Scout Group and member of Riley
Consulting, who project managed the build, turned to Adrian Rigby,
from BHD Architects to design a new structure on the site of the
previous building.
The result was a purpose-built centre, delivering 30 per cent
more space than the original premises. With a tight budget gathered
by almost four years of fundraising by the scout group, specified
products needed to be cost effective and easy to install.
SOLUTION
Simplifying the process of upgrading solid masonry walls, Knauf
Insulation’s Iinternal Wall Insulation (IWI) System is a highly
cost effective solution for achieving increased energy efficiency
in any type of property. Easy to install, a competent builder can
fit and finish the system using a traditional plaster skim finish
or dry lining techniques. No scaffolding is required and the system
can be installed on a room-by-room basis or as part of a whole
house refurbishment plan, as seen here on the Ide Hill build.
The system comprises EcoStuds - extruded polystyrene laminated
to Oriented Strand Board (OSB), which are mechanically fixed to the
internal wall. Earthwool EcoBatt (75mm thick) water repellent, high
performance, glass mineral wool slabs are friction fitted between
the EcoStuds and faced with a vapour check plasterboard sheet.
Earthwool EcoBatts fully fill the insulation zone and are in
intimate contact with the EcoStuds and plasterboard, thereby
preventing any air or draught movement through the system.
To complete the specification of the scout hut, Knauf Insulation
Rafter Roll 32 was fitted in the roof space and Polyfoam®
Floorboard Extra 75mm was used to thermally seal the floor.
Combining high thermal and acoustic performance, Rafter Roll 32 is
a semi-rigid glass mineral wool roll designed for friction fitting
between rafters, while Polyfoam Floorboard is an extruded
polystyrene board that offers excellent energy saving performance,
as well as the strength and durability needed in a flooring
product.
Adrian concluded: “The professional service and knowledgeable
advice we received from Knauf Insulation really helped this project
go smoothly. The Technical Advisory Team was able to recommend the
most appropriate solutions for each aspect of the build, making it
much easier for us to drive the project forwards on schedule.”
