Applications
Moisture can potentially build up under metal roof sheeting and cause structural damage and corrosion of the roof sheet and fixings. ProctorGeo HC20 EnkaVent is used to provide permanent drainage and an air movement pathway between the roof sheeting and roofing underlay to assist in removing moisture. ProctorGeo HC20 EnkaVent also offers significant sound reduction from rain impact noise. When used in conjunction with Proctor underlays and tapes, the HC20 EnkaVent offers a condensation management solution for commercial and residential metal roofing.
HC20 EnkaVent can be used to meet the NCC 2022 deemed to satisfy requirement [Vol 1 (F8D5) 1(b) & Vol 2 (10.8.3)] to maintain a ‘roof space’ that has a height of not less than 20 mm. The ProctorVent VB20 vented batten may be needed to address compression of the ProctorGeo HC20 at the purlins/ roof battens.
Installation
ProctorGeo HC20 EnkaVent should be installed in accordance with the product installation guide.
