The HAPRI Insulation System provides you with the best insulating solution to insulate your External Walls; it is designed to provide thermal insulation with strength and aesthetic appearance. The system is comprised of number of components, when the specified components are combined in the prescribed manner a strong, durable and attractive insulating wall structure will result. This catagloue provide detail on the specification of the components and on the application of these components, including the drawings which further illustrates the correct fixing techniques. The performance of the system is warranted for 15 years- against the full system as long as the integrity of the system is maintained. This means that all the components must comply with Dubai Municipality requirements (see the attached Guarantee certificate) HAPRI-Insulation offers Supply & Apply for the Thermal Insulation System with its accessories & it also offers product for Roof Insulation.

Save Energy Costs upto 40%! There is no alternative! HAPRI Thermal Insulation System Unique Amongst Insulation Systems But in many ways of use. HAPRI wall insulation element has a polyurethane (PUR) high-resistance foam core free of FCKWs (ozone destroyer), which provides the highest possible energy saving with its insulation value ranging from 0.0280-0.0214 W/m.K. The PUR-core is covered with an aluminum foil on the underside to enhances the U- value. The Fleece-coated side, on which the various coatings are applied, such as various kinds of plasters, closers made of natural material, Brick slips or other forms of wall design are just easy to apply, extremely high tensile strength and outstanding coefficient of adhesion. The fiber mesh also gives advantage of more reinforcement to the whole area of where the plaster is going to be applied and the insulation fixing (Poly Porpylene Plugs) is used as a mechanical fixing to fix the board to the wall. Technical Data and Details: HAPRI Insulation board is made of Rigid Expanded Polyurethane, with Aluminum foil on the underside as finish, And top side is covered with a special Polyester Material of high tearing strength and excellent adhesion properties which is designed to hold additional covering layers such as rendering, facing bricks made from natural material etc. • Density: 40-45 kg/m3 (According to ASTM C 303: 2002). • Water Absorption by Volume: 0.03% (According to ASTM C 209: 1998). • Thermal Conductivity Group: k=0.0281-0.0214 W/mK (According to ASTM C518: 2002) • Characteristics in Fire: Building material group, According to DIN 4102 -1/B2 • Temperature Stability: Upto 250°C in short term, constant from -50°C until +110°C • Pressure load: 0,1 N/mm2 oder 10 t/m2, Visco plastic and can be walked on. • Volume Weight: 30-35 kg/m3 • The standard size of Hapri Board is 2mx0.5mx0.04m and the length can be decided according to customers requirements • Hapri Board of 4 cm thickness is laminated with aluminum foil of 14 micron & polyester of 300 g/m2. There is only one insulation material with these good characteristics. HAPRI Insulation Board has 15 years of functional guarantee.

METHOD OF APPLICATION 1.Fixing of Aluminum/ Render Profile: Starting from the walkway level by 25 cm above, fix the aluminum profile, using steel nails, which acts as the base of the system. This profile must have a width of 43 mm for an insulation board of 40 mm, a gap of 3mm is provided for fixing the plaster profile (refer fig-3) later on. The aluminum profile and plaster profile is used for every floor.

2. Leveling the surface of the wall and fixing the Insulation board: Mix Insubond Plaster with water thoroughly to form a paste, (refer technical data of Insubond-conmix plaster). Level the wall by applying Insubond over the surface of the wall & work it out using a threaded trowel. The minimum amount of 1.5kg/m2 of insubond is applied over the first layer. After 5-10 minutes, apply Insubond over the surface of the insulation board (the aluminum foil side) & work it out by threaded trowel, fix the insulation board in a Staggered Method (ref fig-7).

3. Fixing of Plaster Profile, Fiber-Glass Mesh: A plaster profile of width 5-mm is fixed in front of the aluminum profile (ref fig-1) this profile is used as starter for Insubond plaster. To identify the place to be used for fixing the insulation board using Plugs, a certain area is marked using 5mm thick insubond. Over this marked area, and alkaline resistant Fibre Glass Mesh (min 180-200 g/m2) is embedded using a trowel.

4. Mechanical fixing of Insulation Board, Corner Profile: The insulation board and fibre glass mesh are fixed using Propylene Plugs with reinforced Nylon Nail over the marked area. To fix an insulation board of lm2, 10 insulation fixing is needed.(ref fig-7) The method of fixing the plug is shown in the fig-8. Drill the hole of required thickness using 8mm drill-bit, fix the plug & hammer the nylon nail using a mallet (ref fig-7-8). Then apply a prime thin layer of insubond plaster, press gently mesh with the trowel and fix the Corner profile over the corners which gives straight edges for the building (ref Technical data of fiber mesh). After these application the wall is cured for 48 hours.

5. Applying final layer of Insubond: After curing the wall for 48 hours the final layer of Insubond-conmix plaster of thickness 3-5 mm is applied over the area and again the wall is cured for 48 hrs.

6. Decorative Plaster Coating: After the final layer of Insubond is cured and dried, the required finishing coat can be applied either by trowel, roller or spray. The coating can be of different colors & thickness as per the customer's requirements. The decorative layer should not be more than 15mm and it is recommended to use light colored plasters, since it absorbs less heat. Possible options for the final wall designs are: • Trowelled rendering • Float Finish • Variegated stone/ pebble rendering • Plastic flat facing bricks • Facing bricks of natural material • Common cement-lime plaster.
