The Hermes Royal HRT 15 Thermal Anchor

Thermo-Anker/Thermal Anchor HRT 15

The patented Hermes Royal HRT 15 Thermal Anchor lets you attach heavy components with a maximum permitted weight of up to 40 kg (Vzul) per anchor to thermally insulated exterior walls of up to 25 cm thermal insulation compound systems. Whether awnings, balconies, railings, grilles, canopies, conservatories or other constructions, the HRT 15 Thermal Anchor is the perfect heavy-duty attachment for thermal insulation compound systems.

The HRT 15 is inserted into the masonry by means of injection mortar through the insulation and, due to its universal form, forms a tight seal to the outer façade. It is not necessary to use any additional sealing - e.g. with special silicone etc. - which could potentially allow water penetration in future, thus saving you additional expenditure in material and time.

building inspectorate approval

Its building inspectorate approval not only guarantees the safe attachment of loads but also dispenses with thermal bridge effects on thermal insulation compound systems with its heat transmission coefficient (U-value) of ~0.2W / (m2.K). The HRT 15 is available in stainless steel or galvanised steel in two lengths, each with a M10 or M12 threaded mount.
