Technical details

As stated previously, the Alcomij Slimline gable system offers the contemporary look that many growers want. We supply the gable as standard with white PVC strips. But you can also opt for a finish with rubber.

Double pins in the gable connect the glass support profiles and the wall bars. Double pins prevent the gable glass support profiles from tilting. Slimline system grooves are of sufficient depth to absorb scoring of the gable as a consequence of the system’s thermal expansion and shrinkage.

A two-part top bar provides a perfect connection to the side gable at the side of the gutter, ensuring a durable construction.

The insulating gable system

As well as offering optimum insulation and waterproofing, the Alcomij insulating gable system also has the desired presentable and high-quality look.

Suitable for insulating glass

The screw strip ensures that the horizontal bars and vertical stacking profiles provide a precise connection and are finished in an anodised or RAL colour powder coated aluminium end strip. The Alcomij insulating gable is suitable for 6 mm laminated glass or 16 mm insulating glass.
