External Wall Insulation
For Existing Housing
Sto Refurbishment Systems for Social Housing
Robust and sustainable
The UK Government’s target to reduce carbon
emissions by 60% before 2050 is driving
today’s construction policy.
While new build housing projects are already
covered by the Code for Sustainable Homes,
this alone covers a fraction of the homes that
will exist between now and 2050. Meeting the
Government targets will chiefly depend on
improving the insulation of existing homes.
35-40% of the heat in a home is lost through
the walls. There are an estimated 7 million
hard-to-treat homes with solid walls in the UK
that require some form of solid wall insulation
to reduce heat loss.
Sto has developed three external wall
insulation systems for the social housing
refurbishment market.

StoTherm Classic Rapide
A premium system for low to medium
rise buildings. The entirely cement-free
components provide extremely high crack
resistance and the largest colour range.
• Time-saving and compact foam adhesive Sto-Turbofix
for high application speed.
• High performance grey EPS tongue-and-groove
insulation board.
• Finish options: Synthetic silicone resin or acrylic renders.

StoTherm Vario Robust
A low to medium rise system with a modified
mineralic render finish for high levels of
weather protection and longer life than
traditional renders.
• Time-saving and compact foam adhesive Sto-Turbofix for high application
speed.
• High performance grey EPS insulation.
• Finish options: A cementitious dry dash render finish or acrylic / silicone resin
render. If acrylic / silicone resin render is used, a primer will be required.
Resin Brick Slips or Resin Terracotta Tiles also available.

StoTherm Mineral Protect
A high rise system designed to meet strict fire
protection requirements and the widest range
of design options.
• The mineral fibre insulation is non-combustible, for outstanding fire
performance.
• Finish options: A cementitious dry dash render finish or acrylic / silicone resin
render. If acrylic / silicone resin render is used, a primer will be required.
Resin Brick Slips or Resin Terracotta Tiles also available.

Sto-Turbofix
The time-saving, compact foam adhesive
A single component, polyurethane-based
foam adhesive for fixing EPS insulation.
Sto-Turbofix has many advantages over
traditional adhesives.
Quick set
Sto-Turbofix sets in about 10 minutes
and cures in 2-3 hours, ready for
overcoating. This is a significant time
saving when compared to the 24-48
hours curing time for cement-based
mortars.
Rapid pistol application
The pistol and hose allow for quick,
clean and easy application of the
adhesive.
Goes much further
Each 10.4 kg canister of Sto-Turbofix
foam adhesive can fix 50-70 m2 of
insulation, the equivalent of 9-12
sacks (around 270 kg) of cementbased adhesive mortar.
• Easy to handle and store.
• Significantly cuts the amount of
packaging and subsequent waste.
• Less volume cuts down on
transportation requirements and
ensuing carbon dioxide emissions.
Ready-to-use – No water
consumption
Cement-based adhesive mortar has
a heavy water consumption. This is
avoided by using ready-to-use StoTurbofix.

Thermal performance
As a foam adhesive, Sto-Turbofix
has a thermal performance close to
the insulating properties of the EPS
boards.
Colour Visualisation Service from Sto
For enhanced design in the built environment
Architectural drawings or images of a building
can be modified to show a selection of
possible colour combinations that could be
applied. The designs and colours selected can
make a dramatic difference to the aesthetics
of a building.
This colour design service is particularly helpful
for refurbishment projects such as social housing.
Colour combinations and where they are applied
can make a building appear longer, shorter, wider,
as one building or as several. The appropriate
selection of colours on a building facade can
also have a positive effect on the well being of
occupants.
Speak to Sto about our StoDesign services for your
next project.
Render Finishes
For every climate and design aspiration
The choice of finish can depend on a number
of variables: from planning authority policy,
weather conditions to location of the building
and the surrounding environment. Whichever
finish is selected, it can significantly change
and, in the case of refurbishment, enhance the
aesthetic of the building. All Sto render finishes
are sprayable as standard.
The stippled K finish is available for acrylic, silicone and StoLotusan renders in a range of grain
sizes and over 800 colours.
Acrylic render finish
Tintable to a wide
range of colours from
the StoColor System,
acrylic finishes are
vapour-permeable,
highly colour stable and
help to reduce facade
maintenance.
Dry Dash
For a more traditional
look, the Sto Dry Dash
finish copes with almost
any weather conditions.
There is a choice of the
following Sto-Spar Dash
aggregates:
Silicone render finish
Provides high levels of
vapour-permeability
and water repellence.
Ideal for areas exposed
to harsh weather
conditions.
StoLotusan render
finish
A unique, self-cleaning
facade render that
uses patented LotusEffect® technology,
allowing the coating to
shed water with ease,
washing away dirt every
time it rains.

Sto Resin Brick Slips & Resin Terracotta Slips
To achieve a classic streetscape
Sto Resin Brick Slips are flexible, lightweight
and made from acrylic render which simulates
brickwork. They come in standard 215 x
65mm brick size or can be custom-designed to
other sizes, including Resin Terracotta Slips.
Used in conjunction with a Sto external wall
insulation system, they allow for excellent
thermal insulation without having to forego
the appearance of a characteristic brick facade.
