Aluminium Flashings

The patented Flashclad extruded aluminium mechanical flashing system was introduced in 2006 as an alternative to the problematic building practice of relying on sealants and paint to keep the water out. 

Our designs focused on all the critical junctions between the cladding and the joinery without relying on “Sealants”.

Build Magazine 166 – Experts’ highest-priority quality defects

In general, high-priority issues related to practices that allowed moisture to penetrate the building envelope. Problems were also reported with incompatible materials being used together, poor-quality materials or workmanship and poor installation practices. 

Watertightness remains an issue that the New Zealand construction industry must address. Inappropriate sealant use was identified as the highest priority issue. It was felt to be occurring on many building sites and having a major impact on the long-term quality of the building.

Head Flashing

  1. Extruded aluminium head flashing with a combined cavity closure.
  2. Machined aluminium stop ends butting up against the jamb fin.

Jamb Flashing

  1. Revolutionary extruded aluminium Jamb providing back up in the event of water penetrating behind the cladding or joinery frame, managing any water directly on to the sill below.

Sill Support Flashing

  1. The Flashman extruded aluminium sill diverts all the dirt wash and rain water from above protecting the cladding below at the critical joinery base junction.
  2. Our strong sill design incorporates full joinery support eliminating the need for Wanz bars.

Suitable for a wide range of cladding types

Flashman Flashings are suitable for most cladding types. ie: weatherboard, plywood, monolithic and solid plaster.

Flashman can provide sills and jambs in a range of sizes to accommodate the different cladding thicknesses.

AS/NZS 4284

AS/NZS 4284 tested using Flashmans Flashing system in conjunction with Flashclad’s cladding systems. Our test was conducted without the reliance on sealants, foams or plastic back flashings achieving 4.500 kPa = 312 kph wind speeds.
