Plastic styrofoam anchors – reliable fastening for thermal insulation

Plastic styrofoam anchors, also known as façade anchors, are a key element in building thermal insulation systems. They are used for additional mechanical fastening of already glued insulation boards, most often made of EPS or mineral wool, ensuring the durability and stability of the façade system.

One of the main advantages of Styrofoam anchors is their simple and quick installation. The installation process involves drilling a hole with a 10 mm drill bit, inserting the anchor into the opening, and hammering it until fully set. The anchor head, also known as the “mushroom,” holds the board firmly against the surface, while the spiral or fins prevent the anchor from coming out of the wall.

You need to drill a 10 mm hole, then insert the anchor (image 1) and hammer it in until fully seated (image 2).

During installation, the average anchor consumption is 4 to 6 pieces per square meter for flat, wind-protected surfaces. In areas exposed to strong winds – such as building corners – it is recommended to install 10 to 12 anchors per square meter to ensure additional security and prevent the insulation from detaching.

Styrofoam anchors are available in different lengths, depending on the thickness of the insulation layer and the type of substrate, making them suitable for a wide range of construction applications. Their use contributes to the energy efficiency of the building and preserves the structural stability of the façade over time.

Whether renovating existing buildings or constructing new ones, quality Styrofoam anchors are an essential part of every reliable thermal insulation system.
