 Introduction

Exterior Insulation Finishing Systems (EIFS) can be defined as an

energy efficient thermal wrapping applied to the exterior surfaces of
a building which are then finished with a long-life, decorative and
protective wall coating. In the industry these systems are referred
to as EIFS, ETICS, or EWI.

Terraco has been pioneering the development and production of

Exterior Insulation Finishing Systems since the 1980's. Terraco
EIFS combines continuous exterior insulation with design-flexible
aesthetics that ensure indoor comfort and improved energy
efficiency in a single high quality wall system using sophisticated
decorative finishes.

Terraco EIFS has numerous international EIFS quality certifications

and approvals - EOTA (European Technical Approval), BBA
(British Agrément), the US FED Specification Certification, as well
as certification from Ireland, Russia, Turkey, China, Korea and the
UAE.

In many markets, sustainable building and in particular energy

efficiency in buildings, has become a key benchmark of successful
building designs. Today, architects are quick to see the benefits
that these sustainable EIFS building systems give, in both cold
and hot climates. EIFS not only allow designers a very large
degree of design flexibility, but also typically generate an excellent
Return on Investment (ROI) and provide a compelling cost-to-benefit
rationale for the customer.

One of the distinguishing benefits of EIFS is that it can be used for

renovation projects. Terraco EIFS is a preferred choice to make
older buildings more energy efficient, while simultaneously
allowing these buildings to be rejuvenated and given a facelift that
will stand the test of time.

The versatility and durability of Terraco EIFS makes it ideal for new
build as well as renovation projects.

Terraco's three primary Exterior Insulation Finishing Systems use various insulation
materials to meet different climatic conditions and the energy efficient building
requirements of today’s modern society.

Uses Expanded Polystyrene (EPS) as the insulation material in the Exterior Insulation Finishing System. Also includes graphite
enhanced G-EPS.

This system is based on using Extruded Polystyrene (XPS) as the insulation material in the Exterior Insulation Finishing System.

This system is based on using Mineral Wool (MW) as the insulation material in the Exterior Insulation Finishing System.

In addition, Terraco also offers a system for Insulated Concrete Forms (ICF).

ICF is a construction system using expanded polystyrene ‘blocks” (ICF) to provide insulation for both the exterior and interior
walls which are finished using basecoats, reinforced with mesh, and various decorative finishes.

4
 System

Terraco’s best selling EIFS Alpha System is often specified by architects and consultants alike for new and renovation projects.

This EIFS system is based on using EPS (Expanded Polystyrene) as the insulation material. The principal reason for Terraco EIFS Alpha
utilising EPS is because expanded polystyrene is typically the most cost effective insulation board used today, while Graphite Enhanced
Expanded Polystyrene (G-EPS) offers approximately 10% more thermal efficiency and is especially suited to renovation work as thinner
boards can be used.

Terraco EIFS - Alpha System

EPS insulation board G-EPS insulation board

The EPS / G-EPS boards are fixed to the substrate using a combination of adhesive (Terraco Styrofix) and mechanical fasteners, then
reinforced with a basecoat (Terraco Styrobond) and glass fibre mesh, and finished with a primer and decorative wall coating.

Of particular importance to architects and building owners is the decorative finishing coat, both from an aesthetic and a durability
perspective. Terraco offers a comprehensive range of finishing options from long-life acrylic and silicone renders (Terraco Terracoat
range), stone effect coatings (Terraco Terralite range) and breathable mineral renders (Terraco Terol range).

 System

The popular Terraco EIFS Polar System uses XPS (Extruded Polystyrene) board as the insulation material.

XPS is ideally suited to countries which, while being hot, also have high humidity and use air conditioning units inside the building where
XPS’s low vapour permeability is a distinct advantage reducing condensation.

Furthermore, because of the Polar System’s enhanced mechanical properties, it can also be used in high traffic areas or in areas where
a ‘thinner’ insulation material is required. For example, around an opening such as a window or door.

Terraco EIFS - Polar System

XPS insulation board

The XPS boards are fixed to the substrate using a combination of adhesive (Terraco Styrofix) and mechanical fasteners, reinforced with
a basecoat (Terraco Styrobond) and glass fibre mesh, and finished with a primer and decorative wall coating to achieve the desired
architectural appearance.

A comprehensive range of decorative, high build, long-life finishes from acrylic renders (Terraco Terracoat range), stone effect coatings
(Terraco Terralite range) and breathable mineral renders (Terraco Terol range) allows architects and building owners to select the product

 System

Terraco’s EIFS Perma System uses MW (Mineral Wool) as the insulation material and is recommended when a higher fire rating is
required.

Mineral Wool is popular in cold and damp climates, such as in Russia, where enhanced wall breathability is required, something to
consider when insulating structures or old buildings which have high levels of moisture.

Terraco EIFS - Perma System

MW insulation board

The Perma System uses only highly vapour permeable (breathable) decorative renders such as Terracoat Sil or Terol to finish the system.

This EIFS System consists of the following components, the MW being fixed to the substrate using a combination of adhesive (Terraco
Styrofix) and mechanical fasteners, then reinforced with a basecoat (Terraco Styrobond) and glass fibre mesh, and finished using a
decorative, breathable wall coating.

The benefit to the specifier and the customer is that Terracoat Sil and Terol are available in a wide range of colours and textures which
provides them with technically advanced solutions and a high level of durability.

 System

Insulated Concrete Form (ICF) construction systems have proved popular in the United States, Europe and the Middle East for many
years. These systems reduce construction times, have good insulation properties, and reduce energy consumption in hot and cold
climates.

ICF systems use interlocked expanded polystyrene "blocks" as an insulated concrete formwork (ICF) for rapid construction of structural
walls while also providing continuous insulation to both the exterior and interior external walls.

Terraco ICF - Zenith System

When the concrete is poured into the EPS formwork and cured, the EPS exterior and interior walls are finished using a basecoat (Terraco
Styrobond DP HB), reinforced with glass fibre mesh, and finished with:
• Externally - A primer and a decorative wall coating;
• Internally - Terraco Handycoat Interior skim coat over coated with one of Terraco’s Interior Paints and / or Designer Collection products.

As the decorative finish coat is of paramount importance to architects, designers and building owners, they are able to select textures
and colours to meet their architectural requirements from Terraco’s comprehensive range of exterior decorative wall coatings, as well as
the Designer Collection and emulsion paint ranges.

1. Styrofix (Adhesive)
Terraco Styrofix is a polymer modified, dry-mix adhesive applied between the substrate and the insulation board to secure the board
to the wall in the Terraco EIFS System. It is user friendly and factory mixed, improving on site quality control. Styrofix shows excellent
adhesion between various substrates and insulation boards.

• Water resistant • Excellent adhesion • Good flexural strength • Easy to use

MIXING
Mix Styrofix on site with clean water in the ratio of approximately 4 parts Styrofix to 1 part water by weight, mixing with a high speed mixer
for 3 - 5 minutes. Allow the material to stand for 5 minutes, remix and use. Mix only enough material for immediate use.

APPLICATION
Apply Styrofix to the insulation board and ensure the correct level using a spirit level when pressing the boards into place. Do not allow
the adhesive to form a skin before fixing into place.

Spot Method
Apply Styrofix adhesive to 6 inner spots on the back side of
the insulation board, ensuring it covers 40% of the surface
area. (4 - 5 kg/m²)

Ribbon & Dab Method

Apply Styrofix adhesive to the external edges and to 8 inner
spots on the back side of the insulation board, ensuring it
covers 40% of the surface area. (5 - 6 kg/m²)

Notched Trowel Method

Apply Styrofix adhesive to the entire back surface of the
insulation board using a notched trowel. (4 - 5 kg/m²)

Styrofix PU Foam Adhesive

A one-component, low pressure, polyurethane adhesive foam for fixing EPS / G-EPS /
XPS insulation board to a substrate. It is also used for filling gaps between EPS / G-EPS /
XPS insulation boards, between the window / door frame and the insulation board, and for
fixing external window sills. It has excellent thermal insulation and adhesive properties, is
easy to use, economical, odourless, lightweight and quick setting.

The appropriate insulation board and Terraco Exterior Insulation Finishing System should be chosen to suit the requirements and the
project at hand as described earlier.

In order to determine the thickness of the insulation material chosen, the architect needs to know which U-Value is desired for the
building. A U-Value is a measure of energy loss in a building element such as a wall, floor or roof. The higher the U-Value the worse the
thermal performance of the building envelope. Likewise, a low U-Value usually indicates high levels of insulation.

Note: Be sure to use fire retardant boards that comply with applicable national regulations.

11
 System Components

To determine the U-Value of a building element, e.g. a wall, the architect needs to know the different elements and thicknesses that make
up that wall. Each element in that wall has a certain thermal resistance (R-Value) which is derived from that material's thermal conductivity
(K-Value) and its thickness (d).

This data is then entered into the following formula: R-Value = (1/K) x d

These Thermal Resistance (R-Value) values then need to be added up to give you the combined U-Value of that wall.

Thermal transmittance (U-Value) = sum {1/R-Value}

There is a simple rule. The higher the K-Value, the higher the U-Value, and vice versa. Therefore an insulation board with a lower K-Value
can be applied in a lower thickness to achieve the same U-Value as a board which has a slightly higher K-Value.

Please see the table below for an overview.

5. Styrobond (Basecoat)
Terraco Styrobond DP is a basecoat in the Terraco EIFS System. It provides an excellent basecoat for embedding Terramesh glass fibre
mesh on top of which the primer and EIFS finishing coat are applied. It can also be used in place of Styrofix as an adhesive.

• Water resistant • Excellent adhesion • Good flexural strength • Good impact resistance • Easy to use

MIXING
Mix Styrobond DP on site with clean water in the ratio of approximately 4 parts Styrobond DP to 1 part water by weight, using a high speed
mixer for 3 - 5 minutes. Allow the material to stand for 5 minutes, remix and use. Mix only enough material for immediate use.

APPLICATION
Apply a coat of Styrobond DP to the insulation board using a stainless steel trowel at a thickness of 1.5 - 2.0mm and immediately embed
the Terramesh into the surface by trowelling outwards from the centre to avoid any wrinkles. All edges of the Terramesh must overlap by a
minimum of 10cm at all edges. When set (but still plastic), apply a final coat of Styrobond DP to achieve an overall thickness of 3 - 5mm.
Styrobond DP should be allowed to cure for 72 hours before applying the primer and decorative finish.

When used as an adhesive, apply to the insulation board and press into place using a spirit level. Do not allow the adhesive to form a
skin before fixing into place.

6. Glass Fibre Mesh

Terraco Terramesh is used as a reinforcing mesh to enable the EIFS to withstand up to 10 joules of impact. This is equivalent to dropping
a 1 kilogram steel sphere from a height of 1 metre without cracking the surface.

Terramesh is embedded into fresh Styrobond DP basecoat. It is also recommended to:

• Use Terramesh to reinforce corners of all openings such as doors, windows, and recessed features by applying a second layer of mesh
diagonally.
• Apply a second coat of Terramesh and Styrobond DP basecoat to surfaces exposed to high traffic to increase the impact resistance of
the system.

8.3. Terol Mineral Based Renders

Terol is a range of polymer modified mineral renders designed for the finishing of EIFS substrates. Traditionally
Terol, as a decorative finish, is available in the grades: Terol Decor, Terol Granule, and Terol Sahara. These are
typically produced in a white colour and topcoated with Terracoat Stain to achieve the required colour.

New coloured additions to the Terol range are Terol Ultra and Terol Mono. These are revolutionary products that
enable faster application as well as allowing for finishing to be completed in adverse weather conditions. Ter-
raco leads the way in developing new innovative products with the introduction of these new finishing systems.

MIXING
Mix Terol on site with clean water in the ratio of approximately 4 parts Terol to 1 part water by weight, mixing
with a high speed mixer for 3 - 5 minutes. Allow the material to stand for 5 minutes, remix and use. Mix only
enough material for immediate use.

APPLICATION
To create a uniform finish ensure that the water content and mixing time are consistent. Prepared material should be used within 1 hour
of mixing.

Terol Ultra
This product can be applied during the day at low temperatures without having to worry about wash-outs
and night-time sub-zero temperatures. It is designed for application even at low temperatures (4°C to
6°C) and high humidity conditions, in which other ready-mixed renders will not perform because they
need extended drying times. Terol Ultra has a controlled setting time to ensure early rain resistance
and to avoid problems associated with wash-out. Terol Ultra is available in a selected range of fade
resistant shades. Apply Terol Ultra by trowel to achieve a thickness of 2 - 3mm. Clean tools and
equipment with water after use.

Terol Mono
This product is a one-product finishing system for Terraco EIFS. It replaces the basecoat, primer and
decorative finish and allows for all “above-EPS” work to be done on the same day. Terol Mono is a
unique finishing system which can be either a monocouche finish, dry dash finish or a spray finish. It is
a fully pigmented, polymer modified and set-controlled render. It has excellent dirt pick-up resistance
and is extremely stable against UV light even in severe climatic conditions. It can either be applied
manually or by machine and is available in a range of standard colours. Terol Mono is ideal for use on
small fast track projects.

Terol Mono is designed as a one-product finishing system:

Embedding Mortar Apply a coat of Terol Mono direct to EPS surface and use a notch trowel to ensure application is even at
5 - 6 kg/m2. Immediately embed the mesh and trowel into surface.
Finishing Allow material to set for 2 - 4 hours and apply the finishing coat at 7 - 8 kg/m2 by steel trowel. Bring the
surface to a reasonable level and finish according to the desired pattern.

Terol Mono offers the following choice of finishes:

Monocouche finish Allow to set-up for 2 - 4 hours and use a scratch-trowel to remove the top layer of material to create a classic
monocouche finsh.
Dry Dash Finish Once the Terol Mono surface is level, apply decorative stone to the surface by spray or by hand at a rate of
5 - 6 kg/ m2 to create a classic dry dash finish.
Spray Finish Apply a fine spray coat of Terol Mono by hopper gun to create a spray finish pattern. Allow the surface to cure
overnight.

9. Topcoats

When enhanced dirt pick-up resistance is required, Terraco has the perfect solution in its range of specifically formulated topcoats to
ensure enhanced long life finishes.

Terracoat Stain
A ready-mixed, elastomeric pigmented coating, especially designed for application as a topcoat for
cementitious acrylic based textured coatings used in Terraco EIFS, such as Terol.

It has excellent dirt pick-up resistance and is designed for use in areas where atmospheric pollution
is a problem.

Terracoat stain is a low profile coating imparting colour to the surface with minimum film build, thereby
retaining the original texture of the Terracoat textured coatings.

Kode 10
This is a new generation clear topcoat to enhance the dirt pick-up resistance of exterior wall coating
systems. It is ideal for use as a topcoat for organic-mineral renders such as Terracoat and Terralite.

Kode 10 is a film forming coating with excellent durability due to its outstanding hydrophobicity. This
prevents the ingress of waterborne contaminants which cause discolouration and limit the life of such
renders. Kode 10 is based on a novel flouro-acrylic polymer which ensures excellent dirt pick-up
resistance without any of the side effects of conventional hydrophobic treatments.
