...:::... SHAPEMATE IB For External Wall Application ...:::...




SHAPEMATE* IB is used on the outisde surfaces of walls by bounding and dabbling. The boards are produced with rugged front surfaces to increase the paste power for applications from outside. On the back surfaces along its height it is grooved at 5 cm intervals with a size of 5x5 mm. To enable perfect pasting.




- For the external insulation, the boards are pasted to the external face of the wall using cement based pastry mortar without solvent content. (If on the back face there is some kind of painting etc. that is preventing ease of pasting, the surface is to be abrades and thus prepared for pasting).

- The pastry mortar is left drying for a while and the boards are fixed to the surface at the back in rows of 6 for every m2 using plastic nail insulation dabbles. (The dabbling process is very important and if the back face is not right for the process a rough plastering of 2 cm. Thickness is to be provided).

- Cement based plaster with added latex is applied directly onto the surface of the boards in thickness of a few mms. Alkali proof glass fleece plaster rigger filet is pasted onto the plaster surface (before it is dried) using steel trowel. And later a few mm. Of plaster is applied and then left for drying. The most important matter in this process is that the plaster rigger fillet is placed in the middle of total external plaster layer or close to its external face.

- Putting a final layer of cover, which is decorative without any solvent content and has a surface layer, which is rugged but windy, completes the application process.


1) External side of the walls
2) Adhesive mortar
3) Shapemate* IB thermal resistance board
4) Dabble
5) Plaster (min. 2 mm.)
6) Fibermesh
7) Pasting plaster (min. 2 mm.)
8) Plaster


- Shapemate IB thermal resistance boards can be used for the roof of cellars, bottoms of porch balconies etc, and for both columns and beams by putting into moulds as well as by applying plasters later and eliminates heat bridges due to its high thermal resistance capacity.

- The rugged surfaces of the boards tightly grab the surface where it is pasted to and also the plaster it is pasted to remains strong for the length of life of the building and keeps its thermal resistance qualities.

- External insulation protects the external shell of the building against differences in temperatures and thus against wear.

- Applications for external insulation prevent dampness by allowing condensation to occur on the external face of the building and establish a healthy living quarter.

- Applications external insulation eliminates the change of air movement due to the temperature of the wall internal surface being close to ambient temperature and fixed at the ambient temperature. Also prevents erosion of the surface layer, split of the paint and plaster.

- Shapemate IB thermal resistance boards do not require renewal work to be carried out very often and keep their thermal resistance characteristics for the length of the life of the building.

- Allows smaller and more economical use of devices for heating and cooling. Economizes on maintenance and operational work.



MATERIALS FOR THERMAL RESISTANCE (TS 11989 compatible TSE standards). For the application external wall insulation cap less porous polystyrene - extruded foam XPS boards used must definitely have rugged and/or grooved surfaces (TSE 825 standards, article number of attachment number 5 of the official gazette numbered and dated 23725 and June 14, 1999). In the case of surfaces being armored the paste resistance of the boards between paste mortar and plaster shall not be sufficient. (For this reason for the products having grooved and rugged surfaces test results carried out according to TS 11989 by TSE must be obtained from the manufacturers).

RATE OF THERMAL CONDUCTIVITY (LAMDA). It must not be larger than 0.031 W/m.K for aging at 10 C for 90 days. (For boards with both of the surfaces being rugged test results carried out at the laboratories of TSE must definitely be obtained from the manufacturer).

DENSITY. Must not be at lower than 25 kg/m3 density. Although under TS 825, article number of attachment number 5 the lower limit of density is given as 20 kg/m3 for the boards with rugged surfaces we propose values of 27-28 kg/m3 density to be used to be able to reach the value of 0.031 W/m.K.

a) Change of dimensions in the length and the width must be zero at 60 C and 90 % relative humidity.
b) Change in dimensions must not exceed 2 % under 20-kPa stresses and at a temperature of 80 C.
c) Must not exceed 2 % under 40-kPa stresses and at a temperature of 70 C.
Size determination is one of the most important factors especially for the wall applications. Size changes occurring due to differences in temperatures might create problems on the frontal surfaces. The sizes of the cells, their placements and their balances in three directions are very important regarding paste resistance and size dimension involved.

WATER ABSORBTION. The water absorption rate for prolonged periods using full dipping method must not exceed 0.5 % in volume. Otherwise, the thermal resistance material absorbs the water of the paste mortar or pasting plaster it is in contact with and changes the rate of thermal conductivity (lambda) and the building will start to consume more energy than anticipated at the beginning. In addition, as the result of freeze thaw circle of the absorbed water cracks might occur in the plaster.

THE PASTING RESISTANCE TO THE PLASTER. The pasting resistance of the thermal resistance boards to paste plaster must not be lower than 80 kPa. The preferred rates are larger than 100 kPa.

WATER VAPOUR DIFFUSION RESISTANCE. It must be between 90 and 110. The values must remain at these levels so that no condensation occurs at the wall cross-sections and at the same time the building can take wind. However, a test for condensation at the wall cross sections must be carried out under any circumstances (please refer to TS 825 standards given in the official gazette numbered and dated 23725 and June 14, 1999).

PRESSURE RESISTANCE. Must not be lower than 200 kPa (TSE 11989, class C2).

RESISTANCE TO FIRE. Must pass the B2 test first, then must be proven that it has passed B1 class by applying furnace tests and that it has not been dripping. Besides the documents obtained from TSE there must also be certificates granted by the test institutes in Germany.

CAPILARITY. Must be zero.

SPECIFICATIONS OF THE SURFACE. For the application of thin layer pasting, the external surfaces where plaster is applied must only be rugged (not grooved), the back face pasted to the wall must be rugged as well as grooved. Thus, better pasting to the back face shall have been obtained and a relatively more homogenate plaster surface would have been obtained on the external side.


SIDE PROFILES. The long sides being tongued would prevent the work of heat bridges.
