Walls
Energy saving refurbishment with
Remmers IQ Therm System
The listed 19th Century former
Schoolhouse overlooking the
Dublin mountains was renovated
and extended to create a new
energy efficient residential family
home.
So that the exterior facade of the
existing property was not altered
in any way, internal insulation was
installed to the interior of the stone
walls of the original house.
Due to the build up of condensation
behind conventional insulation
when applied to single leaf
construction, it became apparent
that a ‘breathable insulation
system’ would be required.
REMMERS (UK) LTD

Capable of
waterproofing and

it has the highest level of insulation
for given thickness of breathable
systems.
is approved for use in portable
water applications.
It also provides an effective barrier
to the transmission of salts or other
contaminants from the substrate.
The original U-value of the wall
was approx 3.3W/m2K and was
improved to 0.33W/m2K.
It is a high performance
polyethylene membrane which
is extruded into a series of studs
which create a continuous air gap
behind the waterproof membrane.
Remmers IQ Therm is a complete
system of fixing/insulation and
finishing available in 3 board
thicknesses.
On the face of the membrane is a
welded mesh that allows plasters
and renders to bond efficiently to
achieve dry and durable finishes.
The renovation was followed on
RTEs ‘Room to Improve’ house
renovation show with Architect
Dermot Bannon.
