Roof penetration for clay roof tiles: Material compatibility

Clay Roof Tiles and Roof Bushings: What Matters Most

Clay roof tiles are among the most popular roofing materials in Germany. Their natural surface structure, thermal expansion, and glazed or engobed surface place special demands on roof bushings for solar cables.

Challenge of Material Compatibility

Not every sealing material is compatible with clay tiles. Hard plastics can cause stress cracks during temperature changes. EPDM cuffs lose their sealing effect on rough surfaces. The result: leaks that only become visible after months or years.

Why TPU is the Ideal Solution

NEXCAPE roof bushings are made of TPU (Thermoplastic Polyurethane). This material combines crucial advantages for use on clay roof tiles:

  • High Elasticity: TPU adapts to the tile contour without hardening.
  • UV Resistance: No material degradation due to sun exposure.
  • Chemical Neutrality: No reaction with glazed or engobed surfaces.
  • Temperature Resistance: Functions reliably in extreme heat in summer and frost in winter.

Suitable Variants for Every Roofing Project

Variant Cables Available Lengths
2 PV 2 solar cables 105 mm, 125 mm, 150 mm
2 PV+PE 2 solar + earthing 105 mm, 125 mm, 150 mm
4 PV 4 solar cables 105 mm, 125 mm, 150 mm
4 PV+PE 4 solar + earthing 105 mm, 125 mm, 150 mm
6 PV 6 solar cables 105 mm, 125 mm, 150 mm
6 PV+PE 6 solar + earthing 105 mm, 125 mm, 150 mm

Effortless Installation

Another advantage: NEXCAPE bushings can be installed without tools. The MC4 connector does not need to be removed. This saves time and reduces the risk of installation damage to the sensitive clay roof tiles.

Professionally Completing Clay Roof Projects

Those installing on clay roof tiles need material that remains permanently elastic and adapts. NEXCAPE's TPU roof bushings offer exactly that, Made in Germany and manufactured using 3D printing.
