Movement | IKO Permaphalt LI 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 LI 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.
