DCT-W07-2
Externally insulated rainscreen masonry wall (DCT VulcanWool)
Description:
A single skin masonry wall externally insulated with a non-combustible DCT VulcanWool insulation, protected by a rainscreen cladding supported by the Nvelope engineered helping hand sub-framing system. The insulation is mechanically fixed directly to the exterior face of the masonry with minimal thermal bridging, to form a continuous insulation layer. As the stonewool insulation is deemed non-combustible per AS 1530.1, this solution is recommended for type A or B non-combustible wall construction provided the waterproof membrane is not required to be non-combustible.
Section J (NCC 2019) R-Value Calculator
DCT VulcanWool is a non-combustible high density mineral rock fibre stonewool insulation for use internally or as an external grade insulation with water shedding characteristics, designed for use in ventilated rainscreen facades and other thermal and acoustic wall, roof, floor and ceiling applications in residential and commercial buildings.
The insulation shall be DCT VulcanWool thickness [… mm] & density [… kg/m3] non-combustible (AS 1530.1) with a low (<1kg/m2) moisture absorption (EN 1609.) DCT VulcanWool Stonewool is manufactured under licence for DCTech.
Nvelope Rainscreen Back Framing simplifies the complexity of modern building facades using a unique ‘helping hand’ bracketing system which is fixed to the substrate at set vertical and horizontal separations. Suitable for the most demanding facade materials, our range of Nvelope brackets, rails and rainscreen support systems are safe, economic and effective.
DCT Nvelope engineered helping hand sub framing system for mechanical & concealed fixation of cladding panels. Manufactured from 6005a-T5 extruded Aluminium to AS/NZS 1866:1997. Engineered to AS/NZS 1664.1-1997 and compliance to section BP1.1(a),(b)(i)&(iii) from 2019 NCC Volume One for relevant project wind loads. Suitable for use in C1-C5 corrosive zones as defined in AS 4312-2008 & AS/NZS 2312-2014.
