Extruded Polystyrene Panels for ETICS
Initial Arrangement of EPS BOARDS
The initial arrangement of the facade is done through applying of a plinth profile with a drip-edge profile. Choose the profile according to the thickness of the thermal insulating material. The profile is levelled by means of a level and is secured with screw anchors. The purpose of the profile is not only to give a correct horizontal level to the thermal insulation but also to fix and connect the plinth thermal insulation and the thermal insulation system.
Striking the Thermal Insulation Boards
Use Saveto Vetotherm Flex as an adhesive applied over bottom sides of Vetotherm XPS boards. The adhesive is applied as a continuous framework along the edge of the insulation board and in the form of three or four balls in the middle of the board. he boards are stuck to the wall as their adjacent vertical joints should be interchanged like brickwork. Do not leave joints between the boards, and if you get greater gaps, fill them with the insulation material or construction foam, but not with adhesive.
At external edges, the boards should be interchanged. Around the corners of windows and doors you must put whole thermal insulation boards, cut on site along the contour of the hole - so called “gun”. After the complete drying of the adhesive (min. 48 hours), start to grind rough places at the connections between the boards with a special tool.
Start anchoring Vetotherm XPS boards minimum 48 hours after sticking the boards in order to allow the adhesive to dry completely. The dowels should be mounted according to a diagram depending on the height of the building, the region and the strength of the wind.
If Vetotherm XPS have a thickness exceeding 8 cm, you need to make previously a hole of 2 cm depth with a cutter and then, in this hole, to drill an opening for the screw anchor. After the mounting of the dowels, the hole should be filled with a polystyrene cap.
After the completion of the anchoring, cover the heads of the dowels with Saveto Vetotherm Flex to flush with the level of the boards.
Additional reinforcement of the loaded areas
Apply ready to use angle profiles Vetotherm ACP to reinforce external angles. Apply Saveto Vetothem Flex along the edge, place the profile and press it tightly.
Corners around doors and windows should be strengthened by applying adhesive on the base, then place on the adhesive pieces of fibreglass mesh with minimum dimensions of 20х50 cm. Apply more adhesive to cover the mesh completely.
Before continuing to reinforce the entire surface, wait 24 hours to allow these areas to dry.
The substrate should be sound, clean, free from loose material, grease, laitance, dirt, curing compound, etc. Crumbling areas should be removed and the holes must be filed up until reaching a stable base. Uneven base - if deviations are greater than 1-2 cm, the facade should be evened.
Vetotherm XPS is a non toxic material. it is free from Freon gas and it is non-flammable as it contains non retardant material.
