Kalzip® Accessories for roofing systems

Kalzip® E type clip

The patented E-Clip by Kalzip represents a significant innovation in the design of energy-efficient roofing systems. This product is specifically developed to optimize thermal insulation and significantly reduce thermal bridges, leading to a substantial decrease in energy losses. The E-Clip forms a highly insulating layer, thereby improving the overall energy efficiency of the building.

Introduced over 20 years ago, the current version of the E-Clip offers an enhanced combination of increased load-bearing capacity and stability. This improvement is achieved through a steel insert, which provides additional strength. A notable feature is the UV-resistant, fiberglass-reinforced polyamide coating surrounding the metal core, made entirely from recycled material, which exhibits a significantly lower thermal conductivity compared to its fully metallic predecessors.

The E-Clip is instrumental in creating various roof geometries that not only comply with legal requirements but also consider aesthetic aspects of architecture. In an industrial double-layer standard roof construction, the E-Clip achieves a U-value of less than 0.17 W/m·K. With specialized roofing systems such as Duo Plus E and Duo E, these values can be surpassed, with thermal conductivity reaching an exceptionally low U-value of 0.13 W/m·K. Compared to conventional metal clips, the thermal transmittance value of the E-Clip is about 30 percent lower in almost all constructions.

Moreover, the development of the E-Clip has taken ease of installation into account. The metal core not only ensures a stable clip and high load-bearing capacity in the overall construction but also provides safety during installation. The torque-oriented SDK screws engage only with metal, allowing an easy and secure installation of the E-Clips on various substrates. The symmetrical clip head enables quick and error-free laying of Kalzip profile panels. The plastic coating on the clips permits the profile panels to move more easily over them, enabling unhindered expansion and thus safer laying of long profile panels. The E-Clip also meets the DIN 18234 standard for structural fire protection of large-scale roofs.

Kalzip® Bending of flat aluminium sheets

Minimum bending radii must be adhered to when bending flat sheets, depending on the strength and condition of the material. Bending below these minimum values may cause cracks in the material. The following illustration shows the recommended minimum bending radii for the aluminium alloys approved by Kalzip.

Kalzip® Lightning protection

Kalzip^® Lightning conduction and protective screening of buildings protection

Kalzip roof and wall systems are flexible and adaptable to the architectural and technical requirements of industrial, private or public buildings and they offer a safe as well as effective protection against lightning strikes on buildings as well as protection against their electromagnetic impact in electrical systems.

An economic and efficient measure to protect against lightning and its effects can be taken on Kalzip profile boards in two ways:

as a reception device to protect against lightning strikes in buildings
as a building shield against the electromagnetic effect of lightning strikes.

Kalzip® Solar Reflectance, Thermal Emittance and Solar Reflectance

Increasingly there is a requirement for the solar reflectance index (SRI) of materials used for roofing to be known, in particular for buildings in warm and hot climates where the main energy concern is cooling control rather than heating control and which may have to achieve LEED (Leadership in Energy and Environmental Design) certification. The SRI value is determined from a material’s solar reflectance and thermal emittance.

Kalzip® Seam Clips

Kalzip^® Seam Clips

The Kalzip standing seam system is extremely versatile and allows a comprehensive range of Kalzip accessories, such as walkways, handrails, steps, snow guards, photovoltaic panels etc to be safely installed without penetrating the weathering layer of the roof or wall.

The penetration free connection is achieved by the use of stainless steel or aluminium seam clips which clamp over the seam of the Kalzip sheet in order to safely transmit the loading back to the substructure

Kalzip® Fall Arrest System

Kalzip^® Fall Arrest system

Kalzip fall arrest systems (for straight and tapered Kalzip sheets) have been specifically designed using advanced technology and has been fully tested and proven for use on the Kalzip standing seam system. The constant force post and base are manufactured from zinc coated mild steel with the domed cap of the post and all internal performance components made from 316S marine grade stainless steel.

In performance terms the post has an integral high capacity energy absorbing coil which is designed to reduce loads in a fall situation to a maximum of 10kN.

This means that the post nearest to the incident absorbs the impact without transferring the load across the rest of the fall arrest system or onto the roof structure itself. This advanced capability
allows up to three people to be linked to the system at any one time.

Kalzip fall arrest systems are custom designed for each project, using computer design software. This unique Windows® software package models and calculates loadings to determine optimum spacing for the posts

Kalzip® Snow guard system

Kalzip^® Snow guard system

Whilst snow sliding from metal roofs will reduce the loads on them, it can also cause considerable damage to gutters and other roof accessories.

Kalzip’s high performance snow guards are designed and manufactured to
meet customers’ specific requirements and can include two, three or four specially-designed fingers to suit the pan of the roofing sheet.
The snow guards are secured to the roof surface with specially designed Kalzip seam clips, removing the need for roof penetrations, thereby maintaining the roof system’s integrity.
