Head Elements
Single-Head and Double-Head Elements are expansion compensating elements, available in different lengths and with single-sided as well as double-sided vulcanisation. These kind of expansion joints are designed for use on flat roof skirting, wall junction plates and metal covered eaves.
Single-Head Elements must be at least 50 cm longer than the width of the adjoining wall plate or roof sheeting. For example wall plating with a width of 30 cm will require a Single-Head Element 80 cm long.
Double-Head Elements are especially designed expansion compensating elements for bonded inlet type gutters and for graduations in level on buildings.
