Movement

IKO Permaphalt is thermoplastic and is capable of accommodating normal movements encountered in well-designed building structures.

Guidance for specification option:

Structural movement joints within the roof will require the incorporation of a proprietary expansion joint which is compatible with a mastic asphalt roof waterproofing system.

Surface protection

With the exception of vertical and steeply sloping work, the finished IKO Permaphalt must be sand rubbed to reduce the incidence of crazing. A protective surface should be applied to all flat areas using a suitable solar reflective paint, stone chippings or promenade surfacing.

Guidance for specification option:

A protective surface should be applied to all flat areas using a suitable solar reflective paint, stone chippings or promenade surfacing.
