DETAILS OF MECHANICAL FIXING OF INSULATION BOARDS

Mechanical fixing elements are required to prevent the effects of wind and turbulence loads and to ensure o long-term performance of the insulation system. Mechanical fixing anchors shall be fixed at least 24 hours after adhesion.

The type, size and number of anchors are determined depending on the height of the building, surface characteristics, the settlement area where the building is located and the type of thermal insulation boards.

The number of anchors are particularly important at edges due to traction force of the wind load. The width of the edge area must be not less than 1 meter at both corners of the building.

If the height of the facade is higher than its width, the width of the edge area must be equal to 10% of facade width. If facade height is equal to or smaller than facade width, the edge area must be calculated as 10 of the height.

• Land structure 1: Settlements of low density away from center, such as lake side, hills, etc. where 2-3 storey buildings are located.
• Land structure 2: Medium density settlements with elements preventing the wind such as tall trees.
• Land structure 3: High density settlements with high elements preventing the wind, where multi-storey and adjacent buildings are located.

	Generally, 6 anchors per sq.m. are used in applications. Anchors are applied at the center of the insulation board and along all joints where the panels unite.
	At edges and corners, application must be made so that the distance between anchors will be not more than 40 cm horizontally and not more than 25 cm vertically.
	The following order of installation must be used, as given in the diagram, at the sides of windows and clearances.

* Consult to the Technical Service for the type, number of anchors and location diagrams and for more detailed information regarding to the special applications.
