High energy costs but a low comfort level – a growing problem.
Most of the houses in the European Union are more than 30 years old and do not offer the levels of
comfort we expect today. We speak of "thermal comfort" when it is neither too cold nor too warm – in
summer and winter.
Perception of a “comfortable temperature” results from a small difference between interior ambient air
temperature and that of the interior surfaces of the outer walls and windows. In these conditions, one
can enjoy a homogeneous air temperature throughout the whole house or flat and the absence of
annoying drafts.
Older houses were built at a time when the building mentality was very different from that of today,
and when there were no efficient thermal insulation materials readily available.
Although a lot of energy is used to heat old houses or flats, they are overheated in summer and yet
rarely become warm in winter. Despite occupants having to pay high energy bills, for cooling in summer
and heating in winter, thermal comfort is nevertheless not achieved very often.
In view of rapidly increasing energy prices, living in older houses may well become a very expensive
"pleasure", notwithstanding the high consumption of natural resources and the emissions that burden
our environment.
ISOVER dry wall solution – The OPTIMA System
Everyone looking for an efficient, yet easy and quick solution for renovating their own four walls needs
look no further than the OPTIMA System from ISOVER.
OPTIMA is a modern system for easy and rapid renovation or improvement of thermal and sound insulation.
The system solution, with its superbly matched components make assembly simple and easy.
When it is not possible to install facade or wall-cavity insulation, whether for technical, economic or
social reasons (shared ownership), then insulating inside the building is strongly recommended.
The OPTIMA System offers ideal solutions for the renovation and insulation of external walls from the
inside.

OPTIMA – The Innovative Solution
For installing thermal and sound insulation on the inside of outer walls
The Technique
The OPTIMA System consists of simple standard and economical elements:
I. Metal frame (the mechanical structure; Picture 1)
II. Insulation (the thermal and sound layer; Picture 2)
III. Vapour retarder and air tightness layer (Picture 3)
IV. Facing (the finished wall; Picture 4)
The dry lining system is very quick to install and guarantees maximum comfort. In addition, it
can be easily adapted to fit the structural complexity of a building (e.g. tall supporting walls).
Applications
• Thermal and sound insulation of walls in residential or commercial buildings (council housing,
private apartments, individual houses, hotels, hospitals, offices, …) new or for renovation work.
• Dry installation on all types of substrate, including most irregular or uneven surfaces
In short – The Advantages of the OPTIMA System.
• A dry, time-saving solution, which needs no glue mixing and no drying times
• Improved air tightness compared to traditional solutions (joints, thermal bridging/cabling that
compromises the insulation layer etc.)
• Easy cabling and ducting

I. Metal Frame
The mechanical structure
The standard elements that make up the frame ensure the system is both economical and mechanically
stable. The structure can be adapted to fit virtually every architectural situation, producing a
final superbly flat and straight wall surface by ‘absorbing’ unevenness in the original wall.
Intermediate Supports (Item 4 in the illustration on Page 5)
The intermediate supports consist of a spacer bar clipped onto a horizontal stud (OTPIMA2 Support;
Picture 2) or anchored directly to the wall (OTPIMA2 Support Reno; Picture 3). A polyamide key fastens
the insulation material and secures the vertical studs, allowing thickness adjustment with millimetre
precision.
In short – The Advantages of the OPTIMA2 Intermediate Supports.
• Reduced thermal bridges
• Easy and quick to install
• Adjustment possible after installation of insulation material and horizontal studs

In short – The Advantages of OPTIMA Studs.
Joints between OPTIMA 240 Stud and OPTIMA 30 or 50 Studs must overlap at least 10 cm. With an
OTPIMA 240 Stud and an intermediate support fixed at 1.35 m height, the maximum heights to
ceiling are 2.60 m and 2.80 m by adding an OPTIMA 30 Stud or OPTIMA 50 Stud respectively.
• The clip fastener ensures studs are firmly secured in position and will not shake loose
• Time saving during installation
• Adjustment to the nearest millimetre

II. Insulation
The thermal and sound layer
In short – The Advantages of the Insulation Material.
• High performing thermal and acoustic insulation
• Compressed products – easy to handle and install
• Improved acoustics, non-combustible

The glass wool product has to be installed between the wall and the vertical studs
(Item 5 in the illustration on Page 5). As the system guarantees a continuous layer of
insulation material thermal bridges are reduced to a minimum. Pipes and electric
cables can be integrated without degrading the insulation.
Using light weight glass wool insulation material, available in a wide range of thicknesses,
it is possible to gain optimal thermal resistance with minimum use of space.
The material’s flexibility and stiffness ensure the cavity is completely filled.
Products with the lowest thermal conductivity, λd= 0.032 W/(mK) or 0.035 W/(mK), are
preferable as they provide maximum thermal performance with minimum loss of room
area.

III. Vapour retarder and air tightness layer
To avoid condensation damage in the structure, the vapour retarder and air tightness
layer needs to be installed on the inner facing surface of the insulation layer (= the
warm side; Items 6, 7 & 8 in the illustration on Page 5). This barrier prevents water
vapour passing from the room into the construction.
VARIO KM & VARIO KM Duplex UV –
The intelligent vapour retarder and air tightness membrane
outside inside
In winter, ambient relative humidity outside is lower than inside
a building. VARIO KM / KM Duplex UV closes up to prevent the
penetration of water vapour into the construction (Picture 2).
In short – The Advantages of VARIO KM / KM Duplex UV.
In summer, ambient relative humidity outside is greater than
inside a building. In this case VARIO KM/KM Duplex UV opens up.
In this way any moisture in the construction can move into the
interior of the building (Picture 3).
• Dual functionality – humidity regulation: improved and faster drying out in summer, and secure
barrier in winter
• Reliable functionality with matched components
• Vario KM Duplex UV – ease of work: printed guidelines for easy accurate cutting, and fleece surface for
better adhesion to substrate

VARIO – System Components
To ensure minimal energy costs and a comfortable living environment requires not only that a building
should be well insulated but also the building envelope is air tight. The breathable active VARIO KM/
KM Duplex UV membrane represents a new milestone in building technology. The result of its special
structure, the polyamide film boasts a property unique worldwide: In winter when humidity is
relatively low, the pores close, preventing interior water vapour penetrating into the construction.
In summer, with relatively high humidities, the pores open, allowing any moisture that might have
found its way into the structure to dry out. There is no risk of mould formation.
Whereas, standard films do not allow drying out, trapping moisture in the construction, VARIO KM/
KM Duplex UV film is clearly ideal for creating air tight sealing in wall constructions.

OPTIMA System – Solutions for ISOVER Multi-Comfort House*
Today’s modern housing needs to provide much more than basic shelter from the elements – it must offer high standards of quality and
safety throughout. Just as high standards of energy efficiency have now become the norm, families today require a comfortable thermal
environment all year round, and excellent acoustic protection from both internally and externally generated noise. Equally important are
issues such as fire protection and the longevity of the property – and, of course the quality of the internal air within the building.
To address these challenges, ISOVER has developed and refined its Multi-Comfort House concept to offer the ultimate combination of
solutions to meet the demands of modern living.

OPTIMA System – An efficient sound insulation
For acoustic comfort indoors, a house needs to be well insulated against the noise outside. The
OPTIMA System, based on the mass-spring-mass principle, achieves ISOVER Acoustic Comfort
Classes, which generally exceed standard requirements for sound insulation. The OPTIMA System
safeguards personal privacy in the home, maintaining the well-being of its occupants.
Acoustic insulation of a construction is determined by the (weighted) sound reduction index Rw,
expressed in dB: the higher the Rw, the better the sound insulation.
The table below shows some examples of sound reduction for different types of support walls,
insulation and facing materials. Important: sound reduction of 10 dB causes 50% reduction of the
parceived noise!

Sound absorbing elements installed on the walls (Picture 1) and ceilings can significantly reduce echo
in hallways. The OPTIMA System, with a perforated facing is ideal for such situations.

A dry system, easy to install
The OPTIMA System is quick and easy to install, clean and dry. In contrast to traditional dry lining
solutions, adhesives and glues are not needed, allowing installation in unheated rooms or during
periods of frost.
1. Installation of OPTIMA Floor and Ceiling Studs
The position of the OPTIMA Floor and Ceiling Studs is determined by the width of the window frame
(Picture 1, point T) minus the thickness of the facing. Check the frames reference points to ensure
correct positioning of the OPTIMA Floor and Ceiling Studs and correct any possible misalignment.
Mechanical Installation according to the support:
• Pistocelling (ideal for concrete slabs)
• Plugs to be hammered (screw + plug)
If the ceiling is made of concrete blocks, the upper corners can be attached with expansion plugs. To
ensure the joint between the OPTIMA Floor and Ceiling Studs, and the support is air tight VARIO DB
band should be used (Picture 2). Installation in humid rooms requires the necessary protection for
such joints.
(A) OPTIMA Floor and Ceiling Studs
(B) VARIO DB
(C) OPTIMA 240 Stud (horizontal)
2. Installation of OPTIMA 240 Studs and OPTIMA2 Support
In new buildings, horizontal OPTIMA 240 Studs are installed a maximum of 1.35 m from the floor
(Picture 3). Depending on the facing and on wall geometry intermediate OPTIMA2 Supports are clipped
every 60 cm (Picture 4). For renovation work OPTIMA2 Supports Reno are fixed directly to the wall.

3. Cutting and installing the insulation material
The insulation material should be cut to the height floor-ceiling plus 1 cm, and installed
such that the OPTIMA2 Supports pierce the material; panels joints should be tight
and flush (Picture 1).
4. Installing the keys of OPTIMA2 Supports
Locate the key on the projecting end of the OPTIMA2 Support or OPTIMA2 Support
Reno supports (Picture 2 point F).
5. Installing the vertical studs
Insert the OPTIMA 240 Stud in the OPTIMA Floor Stud (Picture 3). Depending on the
height required, affix either an OPTIMA 30 or 50 Stud and slide the extended stud into
position in the OPTIMA Ceiling Stud from the side.
Vertical studs are locked in position by the keys of OPTIMA2 Support or OPTIMA2
Support Reno pieces, first making sure studs are vertical using a spirit level (Picture 4).

6. Installation of the vapour retarding and air tight layer
Once the metal studs are securely located, VARIO KM or VARIO KM Duplex UV can be
applied as a vapour retardant, air tight layer. VARIO accessories, such as VARIO DS,
an adhesive sealing compound, and VARIO ProTape, an adhesive tape, are used to fix
the membrane to the studs, floor and ceiling. The construction is only air tight if
VARIO KM / KM Duplex UV are bonded well to the floor and ceiling. Each membrane
seam should overlap by a least 10 cm (Picture 1).
Applying single-sided VARIO KB1 tape to all membrane seams ensures a reliable, tight
seal. Overlapping the seams by at least 10 cm, and the tape’s powerful bonding
strength avoids leaks in the system (Picture 2).
Cable penetrations are made airtight with VARIO MultiTape SL. VARIO Stos or Mangete
Passelec are also ideal for sealing off various other installations (Picture 3).
7. Cutting and fixing the facing
The facing material should be cut to a length of the floor to ceiling height minus 1 cm.
Hold the board flush to the ceiling and screw it directly to the studs (Picture 4), at
30 cm intervals, leaving a minimum of 1 cm perimeter from the edge of the board.

Dealing with specific issues
Integrating ducts
Standard electrical appliances, home automation and multimedia have led to an increasing in cabling
and ducting that need to be included in buildings (Picture 1).
The OPTIMA System allows the integration of such networks in the lining without compromising
insulation. They are run between ISOVER glass wool and plaster boards. VARIO MultiTape SL is used
to ensure breakout points are both vapour and air tight.
The OPTIMA Connector
This accessory is used to construct
T-joints between OPTIMA transverse and
perpendicular studs, for instance to accommodate
a window frame (Picture 2).
Window sill
The position of the windows has to be taken into account. If it is in the inner surface of the wall,
the length of OPTIMA2 Supports are chosen according to the depth of the window sill.
Humid rooms
In humid rooms (bathroom, garage, non-heated basement), plaster board facings have to be waterrepellent.
Irrespective of whether the floor is rough or finished, an impregnated foam strip needs to
be installed as a central joint (Picture 5 point A) between the bottom wall plate and floor.
Installations on rough floors require additional protection in the form of a polyethylene film overlapping
the floor by at least 2 cm (Picture 5 point B).
