The patented Flashman Window and Door Flashing System is proudly NZ owned. The System was designed by New Zealanders for our unique and demanding climate. Flashings are factory fabricated to precisely fit each individual window or door and then installed exclusively by Flashman Distributor/Installers, providing an advanced flashing system far superior to the NZ Building Code Minimum standard requirements. Flashman ensures Best Practice. Best Practice protects everyone including the Architect. For the first time since the introduction of aluminium joinery in NZ approx 40 years ago, there is now a robust, good looking, long term Complete Flashing System, specifically designed and Branz Appraised to overcome the problematic aluminium joinery to cladding junction. The Flashman Flashing System is supplied and installed only by Flashman distributors who provide a 15 year product warranty, 10 year installation warranty and a Producer Statement. The System is tested and approved up to hurricane wind speeds of 232 kph (Very high wind speed in NZS 3604 is180Kph.) When you specify Flashman it is not an added building cost. The System also saves time and money. The cost of designing, measuring, ordering, delivery, installation of flashings and flashing tapes, Wanz support bars and labour costs associated with flashing windows and doors are often overlooked by all parties. The Flashman System does not cost it saves! The Flashman System has been developed to fully integrate for the first time, the aluminium window and door manufacturing industry with the cladding industry. Flashman is a proven System which provides Architects with litigation protection by greatly reducing the possibility of involvement with troublesome flashing detailing around windows and doors. Can you rely on “tradesmen” to bend up and install flashings around windows and doors? The Flashman System is only installed in cavity construction and thus provides essential risk management value to architects. Unfortunately the building industry often treats the cavity as an internal downpipe. This is dangerous practice which has caused failures already. Conversely the Flashman System does not allow water to enter into the cavity at any time. The Flashman Sill provides full window and door support and also provides neat, clean claddings lines at the bottom of all full height windows and doors. There is no need to install unsightly Wanz Support bars that create an ugly detail below windows and doors. The flashings are powder coated to match or contrast with the windows or doors. There are detail specific drawings for the most cladding types on our website for instant download. Specifications are available on Masterspec. The Flashman System replaces PVC plastering mouldings (masquerading as flashings) buried under a thin layer of plaster in monolithic claddings. Buried PVC mouldings have proven to be the cause of many leaky buildings. PVC mouldings are still being used as flashings today. The problem with PVC flashings is that plaster does not adhere well to them and they contract and expand at different rates to the timber and glass and aluminium they interact with. |
Clean lines to weatherboardWhen the Flashman System is installed facings and scribers are not needed with weatherboard cladding. Architects can now choose to have a clean line around the windows and doors as an alternative to facings and scribers, creating a new, sharp, modern look. Installation of the cladding is faster and easier. Faster enclosure provides a significant cost saving for the builder or developer. The Sill acts as an excellent drip edge avoiding grime and staining to the building. Flashman is specified on new homes, leaky home remediation projects by weathertightness experts and contractors, apartment blocks, rest homes, hospitals, commercial buildings, schools and high rise tower blocks. Flashman are pleased to partner with Architects because together we can raise industry standards and avoid the costly mistakes of the past. The leaky home syndrome has highlighted serious issues with window and door flashings. 50% of leaks in leaky homes and buildings occur around the window and door cladding junctions. One of the main reasons for so many leaks at the cladding to window junction is the widespread misuse of sealant. Sealant should only be used on a 2:1 ratio of width to depth and then only with a bond breaker such as a PEF rod to prevent shrinkage and inevitable leaks. In reality this never happens at the critical cladding to window junction. It should also be noted that sealant does not adhere well to powder coated aluminium. Sealant has failed dismally as an alternative to a long term full metal flashing system but buildings are still being constructed today using sealant as the main method of flashing around windows and door openings. Such detailing will fail in the same way as it has in the past. To add to the problem of incorrect use of sealants (as a main window and door to cladding flashing detail) trade skills have diminished markedly over the last 15 years. Poor flashing practice on the site exposes architects to litigation. Flashman was invented to specifically overcome poor window and door flashing practice and adheres to all four principals of the 4 “D’s”; Deflection, Drainage, Drying and Durability. Flashman employs all 4 D principles but ensures excellent Deflection so that drainage and drying should never be called upon. Extruded aluminium flashings ensure a 50 year serviceable life. The Licensed Builders Practitioners scheme is designed to ensure Architects are liable, responsible and accountable for all weathertightness detailing for a minimum of 10 years. To ensure Best Practice and not Minimum standards Architects are specifying Flashman. |
