What is the ThermoPin®?
The ThermoPin® is an often used tie anchor for sandwich- and element walls and is made of glass fibre-reinforced plastic (FRP). The FRP-bar conducts heat marginally and is used instead of conventional tie anchors for connecting facing and bearing shell of core insulated precast concrete elements.
The ThermoPin® pierces the insulation without being a thermal conductor. In consequence heat loss through tie anchors through the insulation is excluded.
The installation is easy. After concreting the first shell the ThermoPin® is plugged as deep as possible through the insulation into the fresh concrete until the spacer is in full contact with the insulation. The spacer ensures optimal embedment and also serves as a moisture barrier. In the case of a sandwich wall the next layer is concreted on top of the insulation. In the case of an element wall the hardened first shell is turned 180° and placed in the fresh concrete of the second shell. With its conical ends the ThermoPin® has a particularly high pullout resistance.

Horizontal anchor – ThermoPin Type H
For the manufacturing of core-insulated sandwich walls or element walls with a free-standing facing shell the following fasteners should be used to connect the facing shell with the bearing shell:
ThermoPin Type H with a bar diameter of 7,5 mm and conical widening to 10,5 mm at the ends.
The thermal conductivity is 0,5 W/mK.
The ThermoPin is made of non-corrosive, fibre-reinforced plastic material and has a plastic collar as a water barrier and installation aid.
The ThemoPin horizontal anchor is a tensile bar and compression strut in sandwich walls and triple wall systems.
The exact length as well as arrangement and number of ThermoPins results from the statical design.
Diagonal anchor – ThermoPin Typ D
For the manufacturing of core-insulated sandwich walls the following fasteners should be used to connect hanging facing shell with the bearing shell:
ThermoPin Type D with a bar diameter of 7,5 mm and conical widening to 10,5 mm at the ends.
The thermal conductivity is 0,5 W/mK.
The ThermoPin is made of non-corrosive, fibre-reinforced plastic material and has a plastic collar as a water barrier and installation aid.
For a sandwich wall with a hanging facing shell the ThermoPin Type D must be used in addition to the ThermoPin Type H.
The ThermoPin Type D is a support anchor for transferring load from the facing to the bearing shell.
In the upright wall the anchors are inclined at an angle of 45°.
The exact length as well as arrangement and number of ThermoPins Type D results from the statical design.
