energy efficient
Icopal is the world's leading producer of
membranes for roofing. We have 29
manufacturing plants in Europe and America
and distribute our products through 79
subsidiaries in Europe, America, the Middle
East and Asia.
From our UK head office in Manchester, and
through a national network of 2,200
distributors, we offer the UK construction
industry the most complete range of
construction membranes backed by support
services and insurance-backed guarantees.
We combine the resources of an international
company with intimate knowledge of the
requirements of local markets. We work with
construction industry professionals to identify
problems and develop solutions for better
buildings - solutions which are innovative,
sometimes unique.
Icopal has pioneered the use of membrane
technology to improve building performance
by controlling the movement of water, air and
heat. Designers can rely on Icopal membrane
systems to produce energy efficient,
sustainable buildings.
Vapour open membranes
Icopal has produced vapour open membranes
since the 1970s, when we pioneered the
concept of membranes which are vapour
open, watertight and airtight. Monarperm 700
is the latest addition to the Icopal family of
membranes.
Monarperm pitched roof systems
The construction of efficient pitched roofs
requires consideration of the performance of
all the materials involved and their interaction;
it is not sufficient to rely solely upon any one
component. In order to assist designers in the
creation of high performance pitched roofs,
Icopal offers several pitched roof systems.
Each system comprises membrane and
accessories which give the best performance
for any given roof type. The following pages
provide details of those materials and
accessories and describe the key design
considerations for each type of roof.

Airtight: Monarperm 700 helps prevent
the displacement by the wind of roofing
tiles and slates.
Watertight: Any wind-driven rain or snow
which penetrates the tiles or slates is
stopped by the Monarperm 700 underlay and
drains safely down to gutters.
Vapour open: Monarperm 700 allows
water vapour arising from the occupied
space to diffuse safely to atmosphere;
it prevents the build up of high concentrations
of water vapour, so reducing the likelihood
of harmful condensation.

The performance of Monarperm pitched
roof systems can be enhanced by the use
of Monarperm air leakage barriers (ALB):
they are:-
Airtight: Monarperm air leakage barriers
reduce air movement through the roof,
cutting convection heat losses resulting
from air infiltration. Such heat losses can
represent as much as half the total heat
loss through the roof.
Vapour tight: Monarperm air leakage
barriers reduce the transmission of water
vapour from the occupied space into the
roof structure.
By preventing the build up of moisture
within the roof Monarperm air leakage
barriers minimise the risk of interstitial
condensation.
Heat reflective: When fixed on one face
of an unvented cavity Monarperm HLB
200 reflects much of the heat radiated
across that cavity. The reduction in
radiation heat transfer can make a 10%
improvement in the thermal performance
of the roof.

Monarperm Eaves Guard
Monarperm Eaves Guard is designed to prevent
ponding behind a fascia board (see BRE Defect
Action Sheet 9); and to eliminate the need for a
tilting fillet. It also protects Monarperm 700 from
prolonged exposure to UV light at eaves.
Monarperm Eaves Guard EG300 is suitable for
roof pitches down to 12.5º. Monarperm Eaves
Guard can be installed before or after the gutter.
Monotape
Monotape is a double sided acrylic tape for
joining laps in Monarperm 700 to form a
continuous vapour open underlay.
Monobond
Monobond is a permanently flexible butyl strip
designed to remain flexible at temperatures down
to -40ºC with an application temperature of +5˚C
and above. It is ideal for joining polyethylene
membranes - such as Monarperm 700 and
Monarperm ALB 200. It should be used to seal
laps to form vapour control layers and air leakage
barriers and to seal them to adjoining elements.
Monosleeve
Monosleeve is a flexible sleeve designed to seal
service penetrations through Monarperm ALB
200 and Monarperm HLB 200. The rubber sleeve
fits tightly around the pipe or cable whilst the self-

Back to basics
A fundamental requirement of any building
is that it should provide a suitable internal
climate for the occupants and their
activities: that will usually involve keeping
the weather out, keeping heat in, avoiding
a build-up of moisture and providing
sufficient fresh air. Building Regulations
stipulate the following requirements:
� Part L in England and Wales
(Section 6 of the Technical
Handbooks in Scotland, Technical
Booklet C in Northern Ireland)
- designers must limit carbon dioxide
emissions by conserving energy. In
addition to addressing heat losses by
conduction through the building
elements, designers must consider
thermal bridging at junctions and the
effects of air infiltration upon overall
building performance.
� Part C in England and Wales
(Sections 3.10 and 3.15 in Scotland,
Technical Booklet C in Northern
Ireland)
- buildings must be designed to resist
water penetration and avoid damaging
condensation.
� Part F in England and Wales
(Section 3.14 in Scotland, Technical
Booklet K in Northern Ireland)
- there must be sufficient ventilation for
the building occupants.
Conventional methods
The conventional approach has been to tackle
those requirements separately, and accept the
resultant inefficiencies. For example, the
conventional solution to harmful condensation
in pitched roofs has been to vent the airspace
beneath the impermeable underlay. Whilst that
does prevent condensation it also increases
the rate of heat loss through the roof and
encourages air infiltration into the occupied
space.
As the requirements of the regulations are
tightened such a piecemeal approach will not
suffice: specifiers must adopt a holistic approach
to the management of heat, air and moisture.

Monarperm Pitched Roof SystemsDesign considerations
Monarperm 700 30/6/06 2:25 pm Page 8
Holistic design
The key to achieving holistic solutions for
pitched roofs is to identify the external and
internal control planes for each building
element and use materials with the right
combination of properties to form those
planes.
The external control plane on a pitched roof
should:
� Protect against water ingress - a
waterproof membrane is required
behind discontinuous roofing units
such as slates and tiles.
� Reduce unnecessary air movement
from outside to inside, so improving
the thermal performance of the
roof.
� Allow any moisture which does
diffuse from the occupied space
into the roof to pass safely into
atmosphere.
Those requirements can best be met by
using Monarperm 700 watertight / airtight /
vapour-open membrane.
The internal control plane should prevent air
filtration through the construction in order
to:
� Reduce convection heat loss
� Prevent vapour transfer by diffusion
Those requirements can best be met by
using Monarperm ALB200 vapour-tight
airtight membrane.
The use of Monarperm HLB 200 to form
the internal control plane will also:
� limit radiation heat loss
The figure below shows the balance of properties required in a roof construction.
Adopting membranes to form control planes, and correctly detailing their
junctions, enables designers to create weatherproof, draught-free buildings
which will be energy efficient and free from condensation.
Once air infiltration has been addressed, designers can set about providing
correct levels of ventilation.

Eaves
Insulation
Monarperm 700
MonarflexEaves Guard
CounterbattenThe Monarperm warm
pitched roof system
In warm pitched roofs
insulation is installed in
the plane of the rafters:
over and between the
rafters, wholly between
the rafters, or between
and beneath the
rafters. Warm pitched
roofs may be used to
provide an additional
storey, to form a
cathedral roof or to give
a conditioned roof void.
The Monarperm warm
roof system uses
Monarperm 700 to form
the external control
plane and Monarperm
ALB 200 or Monarperm
HLB 200 as the internal
control plane.
In the Monarperm warm roof system
Monarperm 700 prevents water
penetration, reduces air infiltration and
allows any water vapour within the
structure to escape. To obtain maximum
benefit from the system all laps in
Monarperm 700 should be sealed with
Monotape; junctions between the
membrane and adjoining elements should
be sealed with Monotape or Monobond.
Monarperm 700 is fixed by
counterbattens: they allow water to drain
from the roof and form a deeper air space
to aid the dispersal of water vapour. The
gaps between tiles and natural slates
provide sufficient air paths for water vapour
to disperse to atmosphere: for tighter
coverings it may be necessary to vent the
batten space at the top and bottom of
each slope (see BS 5250 section 8.4.2.1.2
for guidance).
Monarperm ALB 200, or Monarperm HLB
200, reduces air infiltration and prevents
water vapour generated within the
occupied space entering the roof. Icopal
recommends the membrane be fixed to
the underside of the rafters with battens.
The voids formed by the battens enable
services to be installed without penetration
of the membrane and, if used in
conjunction with Monarperm HLB 200,
reduce radiation heat loss.
All laps in Monarperm ALB 200 or
Monarperm HLB 200, and junctions
with other elements should be
sealed with Monobond. Service
penetrations should be formed
with Monosleeve.

In the Monarperm sealed cold roof system
Monarperm 700 prevents water
penetration, reduces air infiltration and
allows any water vapour within the
structure to escape. To obtain maximum
benefit from the system the membrane
should be laid taut and all laps in
Monarperm 700 should be sealed with
Monotape; junctions between the
membrane and adjoining elements should
be sealed with Monobond.
Monarperm 700 is fixed by
counterbattens; they allow water to drain
from the roof and form a deeper air space
to aid the dispersal of water vapour. The
gaps between tiles and natural slates
provide sufficient air paths for water vapour
to disperse to atmosphere: for tighter
coverings it may be necessary to vent the
batten space at the top and bottom of
each slope (see BS 5250 section 8.4.2.1.2
for guidance). There is no need to maintain
ventilation paths at eaves; they may be
packed with insulation to reduce thermal
bridging.
Whilst the system will work satisfactorily
with a well sealed ceiling (see page 12), its
performance may be enhanced by forming
an internal control plane with
Monarperm ALB 200, which will
reduce air infiltration and prevent
the transfer of water vapour to
the loft by diffusion.
10
Monarperm Sealed Cold Roof System
The Monarperm sealedcold roof system
In cold roofs insulation is
laid at ceiling line, between
and above the joists, with
the loft and roof structure
outside the insulated
envelope giving rise to a
risk of harmful condensation.
The Monarperm sealed
cold roof system eliminates
that risk by using
Monarperm 700 as a
vapour open external
control plane and
Monarperm ALB 200 as a
vapour-tight internal control
plane. There is no need to
vent the loft to atmosphere.
With no ventilation, the air
in the loft forms a buffer
which reduces air infiltration
to the loft both from outside
and from the occupied
space; that, in turn,
reduces moisture transfer
into the loft and cuts
convection heat loss.
The Monarperm sealed
cold roof system is suitable
for use with board sarking
with at least 5mm gaps
between boards (for sheet
sarking see page 12).

Monarperm Vented Cold Roof System
The Monarpermvented cold roofsystem
The Monarperm vented
cold roof system offers a
conventional solution to the
control of condensation in
the roof.
Whilst ventilation of the loft
will generally prevent the
occurrence of harmful
condensation it also results
in unnecessary heat loss
through air infiltration and a
reduction in the
effectiveness of fibrous
thermal insulation in the loft.
Monarperm 700 may be
used in exactly the same
way as 1F felt, but is easier
to install as it is lighter and
handles better on the roof.

Well sealed ceilings
The following measures are essential for
achieving a well sealed ceiling:
� access hatches should be adequatelysealed and not sited in kitchens orbathrooms;
� the heads of wall cavities should besealed;
� the ceiling should be sealed to the externalwalls;
� penetrations for services should bepermanently sealed with Monosleeve;
� recessed light fittings should be airtight or be hooded or boxed.
(see BS 5250 section 8.4.1.2 for furtherguidance)
In the Monarperm vented cold roof system
Monarperm 700 should be draped over
the rafters leaving a minimum 25mm gap
between the membrane the underside of
the tiling/slating battens to allow water to
drain from the roof.
The Monarperm vented cold roof
system is suitable for roofs which
include board or sheet sarking. In
a conventional sarked roof the
slates would be nailed to the sarking,
puncturing the membrane in many
places: that may be avoided by fixing
counterbattens and slating battens to
the sarking and then slating the roof (see
page 13).
Ventilation should be provided in
accordance with BS 5250 section
8.4.2.2.3 (summarised in the figures on
page 13). The depth of insulation required
to meet Part L - approximately 300mm -
can make it difficult to maintain a clear air
path at eaves: designers should consider
alternative locations for vents, such as
gable walls.
A well sealed ceiling is recommended to
minimise the transfer of water vapour into
the loft by air infiltration. The installation of
Monarperm ALB 200 between the ceiling
and the insulation would reduce further the
amount of water vapour reaching the loft.
