NOTION_flo X Weathertightness & Cladding

March 31 @ 10:00 am - 4:00 pm

Keep the outside out and the inside in with this event that focuses on how to design assemblies that are durable, redundant and weathertight for the duration.

10am – 10:15am

Welcome by Peter Raimondo, Oculus Architectural Engineering Ltd as MC

10.15am – 11.15am

Antoni Rajwer

DuPont ANZ Ltd 

Identifying and resolving weather barrier problems that can affect long term building durability is key to designing and building robust, weathertight buildings. Find out the various mistakes that happen in builds that prevent weathertightness.

Weather barrier overlaps not taped or sufficiently lapped. Just like unzipping your jacket on a cold, wet, windy day, both moisture and wind-washing can significantly affect insulation performance.Flashing tape incompatible with weather barrier. The flashing tape does not stick effectively and allows bulk water to enter the wall cavity.

11.15am – 12.15pm

Omega Windows and Doors

A thermal break is a non-metallic resin or plastic material installed in the metallic windowframe that physically separates the interior part of the window from the exterior part. Hence the pathway for heat energy to be transferred or conducted through the window frame is “thermally broken – how can specifying the right joinery impact weathertightness in the build.

Break – 12.15pm – 1pm

1.00pm – 2.00pm

Jon Davies

Oculus Architectural Engineering Ltd

Along with the Oculus team he’s working on a testing rig for testing building facades to AS/NZS 4284. Architect should be really interested in this because it’s a critical test for checking that a cladding system is actually weathertight. The test should be done more often than it currently is. There are only a handful of places where the test can be done in New Zealand, and it’s great news that Auckland will soon have another facility for this purpose.

2.00pm – 3.00pm

Jackson Powell

Premier Brick

The biggest difference between brick veneer and solid brick is the main building support. Solid masonry is the structural support of the building. With brick veneer, the structural support comes from the concrete, steel, or wood that makes up the backup wall, and the brick is on the exterior for aesthetic purposes.

3pm – 4pm

Reducing Energy consumption and carbon emissions with High performance windows

The building envelope plays a significant role in the energy performance of buildings and windows are a key element in transmitting heating and cooling between the indoor and outdoor environment. Currently, focused efforts are being made to determine the influence of windows on the energy consumption and economy of buildings. Certain window designs and appropriate glazing systems reduce energy consumption for heating and cooling and contribute to building economy. This presentation explores the effective strategy of utilising high performance windows in building design to reduce energy consumption and costs and deliver real reductions in greenhouse gas emissions.
