3 Why External Wall Insulation? In a typical building structure, around 30 % of the energy used to heat or cool a house is wasted due to poorly insulated walls. External Insulated walls significantly cut energy loss by wrapping the building with thermally resistant envelope, helping to reduce energy bills and CO 2 emissions. They also provide life time protection for the building and comfort to occupants. Insulation can be installed in new as well as existing building which will increase the thermal and acoustic comfort of the building. As Glass mineralwool insulation is non-combustible that drastically reduces the fire risk of the building. Apart from these performances, external wall insulation also increases the life and value of the building.

4 Thermal Insulation Loss through Walls 25% - 30% Roof Loss 25% - 30% Around 60 % of the total heat loss / gain is through walls and roofs, hence insulating the building is an important factor to achieving thermal comfort for its occupants. Insulation reduces unwanted heat loss or gain and can decrease the energy demands of heating and cooling systems. Regardless of the temperature/season outside the building, occupants will always enjoy the comfort inside the building when it is insulated with KIMMCO Glass Mineralwool. Floor Loss 7% - 10% Door Loss 15% - 20% Window Loss 10% - 15% Thermal Bridges Thermal bridges are weaknesses within a building's structure where heat and/or cold is transferred at a substantially higher rate than through the surrounding envelope area. It is advisable to eliminate thermal bridge by using suitable fixtures, which will result to increase the comfort and Energy saving in the building. Product K Value (W/m.k) at 25 o C Mean Temp.

5 Thermal Insulation Thermal Resistance (R-value) An R-Value is the measurement of a material capacity to resist heat flow from one side to other, in simple terms, it measures the effectiveness of insulation. The higher number of R-value will represent more effective insulation i.e. more energy savings. For example, the following table shows the thermal resistance (R) of KIMMCO insulation for each standard thickness at 25 C (77 F), according to S.I. and IMPERIAL Units System. If you insulate 20,000 villas, it will eliminate the need of 2000 Million watt of Power station Product KIMMCO Safe Façade Insulation 035 Thermal Resistance (ft 2.h 0 F/Btu) at 77 0 F Mean Temp Thermal Resistance (m 2.K/W) at 25 0 C Mean Temp. 50 mm 100 mm 50 mm 100 mm KIMMCO Safe Façade Insulation KIMMCO Safe Façade Insulation

6 Fire Safety Most of the building codes insist on using non-combustible insulation material for the Façade application. Beside non-combustibility, it is also important to consider fire resistance of the building components. Fire protection has always been a big concern for building occupants, fire fighters, building owners and people living in the vicinity. Fast innovative construction and availability of variety of material in the market always create a confusion in selecting the suitable product for its application. KIMMCO products are made from recycled glass and sand which are naturally non combustible and do not support flame spread nor release toxic smoke Passive Fire Protection Design It is very essential for the consultant/ designers to choose passive fire protection materials with great care and attention to detail. As in many cases active fire protection systems can be added at a later stage but passive systems has to built during the time of construction. Insulation products are one of the key component of passive fire protection systems. Non-combustible Insulation products should always be chosen with the best fire protection properties likewise Glass Mineralwool insulation when tested in accordance to ABS certification, ASTM E 136 & BS 476(Part 4).

7 Fire Safety Reaction to Fire The reaction of material to fire is defined using the European classification system in Euroclasses A1 to F. The classification is based on the properties of the material under the influence of fire, smoke production and burning droplets. Using the classification system, a material's contribution to the spread of fire and smoke can be established, including if the material has a tendency to contribute to a flashover. Non-combustible materials and products (A1 and A2) do not cause flashover. For example: KIMMCO Glass Mineralwool products without a facing are classified as Euroclass A1, products with a facing of aluminum foil or glass facing tissue are classified as Euroclass A-2s1d0 or B-s1 d0. Where products are exposed to an impact of fire, the fire safety requirements must be met with respect to ignition, flame spread, smoke development and burning droplets. KIMMCO's products meet the most stringent requirements for surface layers, which means that they can be used in all parts of a building applications. Apart from European standards, KIMMCO Glass Mineralwool products are classified as non combustible according to the American standards ASTM E136, British Standards BS 476 (Part 4), and French regulations.

8 Acoustic Insulation Acoustic Performance We are living in a noisy world where we are continuously exposed to several kinds of low to high frequency noises that we do not want. Noise from outdoors such as traffic, aircraft, voices often affects our peaceful and quiet living atmosphere at home or office. Similarly, noise from equipment, machinery, telephones, ventilating systems divert our focus and make us less productive day by day. Sound Reduction Sound reduction is defined as a sound that passes between two spaces separated by a dividing element. In transmitting between two spaces, the sound energy may pass through the dividing element (direct transmission) and through the surrounding structure (indirect or flanking transmission). In designing for sound insulation, it is important to consider both methods of transmission. The walls or floors, which flank the dividing element, constitute the main paths for flanking transmission, but this can also occur at windows, heating or ventilation ducts, doorways, etc. The acoustic environment of the room and/or the building and the ability to reduce or eliminate air paths in the vicinity of the sound reducing element, e.g. Roof insulation (under deck & suspended ceiling), cavity walls, Curtain walls, ductwork, etc, will have a significant effect on its performance. Acoustic Insulation The elastic structure of the Glass mineralwool permits the separa tion of the two elements of a double wall, thus assuring the noise coming from outside is acoustically reduced. The low dynamic stiffness of the Glass Mineralwool insulation permits the use of the "mass-spring-mass", system in place of the "mass law", which is limited as the weight becomes quickly an obstacle in construction. mass m spring mass wall GW wall r m m r m

9 Façade Insulation Façade - The meaning of Façade is the a front face of a building / External wall of a building. Façade is the most important aspect from design point of view, as it gives the first impression of the building but it also provides a great importance due to the impact on energy efficiency and fire protection. In general the Façade of the building should function as a climate barrier and shall protect against heat, cold, noise & fire, which also will provide comfortable indoor environment in terms of Thermal & Acoustic performance to the occupants.

10 Façade Wall Cement Block Vertical Channel Safe Façade Insulation Fastener Air Gap Aluminum Composite Panel Curtain wall systems are a non load bearing systems for the external walls of the buildings. They are generally associated with large, multi-storey buildings. Curtain walls separate the interior from the exterior, but only support their own weight and the loads imposed on them (such as wind loads) which they transfer back to the primary structure of the building. Curtain wall can be installed in existing buildings as well as new buildings. KIMMCO Safe Façade Insulation products are available in BGT facing & FS facing.

12 Cavity Wall Insulation A cavity wall is made up of two walls with a gap in between, known as the cavity; the outer leaf is usually made of brick, and the inner layer of brick or concrete block, Cavity is usually filled with Insulation to get an excellent Thermal & Acoustic comfort. KIMMCO s Safe Cavity insulation range achieves best thermal, fire, acoustic and easy to install performances. The products are named and classified according to their comfort efficiency. Cement Brick Wall Tie Safe Cavity Insulation Cement Block Screed/ Plaster If the cavity is left empty, air movement constantly heats up the inner leaf. As the outside temperature heats up, more and more energy is lost. Filling the cavity with the KIMMCO insulation material reduces the heat gain during summer and het loss during winter through the building.

13 Do s Do cut the insulation using a sharp knife and straight edge. Do fit small pieces of insulation with the fibres running horizontally to the wall to ensure fully-fitted. Do keep the top edges of the insulation clean of mortar by using a cavity board. Do protect all exposed areas of insulation with a weatherproof material or board when work is suspended or during rain. Don'ts Do stagger vertical joints and ensure they are tightly butted. Do not pierce the insulation with wall ties to prevent tearing the insulation, creating a potential themal bridge. Do not push insulation down into the cavity as a tightly butted horizontal joint cannot be ensured. Do not bend insulation around corners as this creates air pockets within the cavity.
