Construction Fixings

A new high-quality, die-cast zinc screw, featuring a pre-mounted EPDM seal, and specifically designed for direct fastening to insulated façades, has been launched by international fastener and fixings maker CELO. 

CELO states that the new IPSZ insulation screw is versatile and compatible with all common types of insulation and offers optimal performance when secured through standard 8mm through-holes. The company reports that the screws are also ideal for installing light loads, such as wall connection profiles, plinth protection strips, signs, or lamps on insulated and plastered façades. They can also installed directly in ETICS and wood fibre insulation without pre-drilling – due to the sharp drill tip of the screws, in turn saving time.

The new screws include two different lengths in order to cover a wide variety of insulation materials. The IPSZ 80 screw, for example, offers secure holds on ETICS insulated faÇades of 80mm thickness and with materials including EPS, mineral wool, polystyrene foam boards, rigid foam boards or polystyrene boards. The IPSZ-H 55, on the other hand, is the shorter version and suited for use with wood fibre insulation boards and perimeter insulation of 60mm thickness.

CELO also points out that the IPSZ screws are energy efficient, as they prevent thermal bridges and the penetration of moisture into the façade. In addition, their TX drive ensures good power transmission – with the right bit size and means they can be installed with a standard cordless screwdriver. Their pre-mounted EPDM sealing ring also means that no subsequent sealing is necessary, thus reducing the amount of insulation steps required on a job. The strength, durability and corrosion resistance of the new IPSZ screws is also ensured through their zinc die-cast construct.
