Fastwrap Wall for Transportable Charity Home Project

PI_2

Company: Paul Industries

With its ‘go anywhere, do anything’ credentials, Fastwrap Wall Underlay was an obvious choice for the Kapiti Mitre10 Mega Charity house project for the Kapiti Youth Achievement Trust. Supplier Paul Industries jumped at the chance to support this community initiative.

“It’s such an exciting and worthwhile project” enthused Ben Lloyd, GM Sales & Marketing for Paul Industries. “The home will be built by volunteers using donated materials and expertise then sold at auction, with the proceeds going to the Kapiti Youth Achievement Trust. It will also provide an opportunity for students at Whitireia and the general public to improve their understanding of current building codes and some of the newer products on the market.”

Award winning architectural practise, AD Architecture, who designed the home and are overseeing the build, felt that Fastwrap Wall Underlay was a natural fit for the project. “We use Fastwrap Wall as the ‘go to’ synthetic wall underlay for all our projects” said Peter Davis, Director of AD Architecture.

“We see it as a specify-and-forget product because it’s appraised for use in all areas and all applications – we know we can use it on any job, in any location”.

Other Paul Industries products to be used on the project include Fastwrap FlameSpec Roof Underlay, Kiwimesh Roof Safe Mesh and Pauloid DPC.

The charity house project uses an innovative modular design by AD Architecture and has the advantage of being fully transportable. “Portability is a key element for this project as the owner can simply pick the completed house up and move it to a site of their choice. This meant that specifying products that will stand up to all NZ conditions, including the highest wind zones was essential” added Peter.

The modular design concept means that additional rooms can easily be added at a later stage and reflects AD Architecture’s commitment to providing smaller, smarter housing solutions. There is also careful consideration given to living comfort and energy efficiency and it’s expected the home will rate well with Homestar.

Colt Products and Systems Recently completed Auckland’s Devonport Library

Colt_1

Company: Colt Products and Systems

The recently completed Devonport Library was designed by Athfield Architects. When it came to specifying ventilation, Colt Products and Systems were the obvious choice.

Nestled amongst the palm trees with views out to the harbour, this beautifully crafted library pavilion incorporates floor to ceiling Coltlite glazed natural ventilators for both natural light and ventilation. Coltlite’s European high standard of craftsmanship supports the light airy aesthetic, without detracting from the views, and provides controllable natural ventilation throughout.

The specified control system modulates the louvre blades, to regulate the airflow by varying the degrees of open/closed. The CLT Louvre system, controlled by the BMS, also allows for automatic control for changing weather conditions and connects to a rain, wind and temperature sensor for natural ventilation.

Of particular interest to the designers was the reliability backed up by extensive testing to EN 12101-2 as a dual purpose Smoke Heat and Exhaust Ventilator, backed by CE marking.

Coltlite ticked all the boxes for reliability and with the outcome – naturally ventilated atmosphere that has surpassed expectations.

PATAKA Art + Museum Reclad with James Hardie Stria® Cladding and CLD® Structural Cavity Batten

JH_1

Company: James Hardie

Project Overview

North of Wellington, PATAKA Art + Museum is a leading regional centre for art and culture and is the cultural heart of Porirua City. Owned by Porirua City Council, the Museum opened in 1998 in a building named Te Marae o Te Umu Kai o Hau. Poor installation of the existing cladding has caused weathertightness issues and two-thirds of the building’s exterior needed to be reclad. The remaining third of the building comprises aluminium joinery and external louvres configured into a basket weave pattern, which screen north facing windows.

The Solution

James Hardie Stria Cladding on a CLD Cavity system was specified by local designer and project architect, Rory Hocking of Ergozign Design Ltd. The products were supplied and installed by Nick Jenness of LNA Cladding Services Ltd, a Recognised James Hardie Installer.

“Stria Cladding was an apt choice for this reclad project. It provides crisp, clean lines, which contrast nicely with the external louvres and also match the contemporary feel of this much- loved community facility,” says Jenness.

LNA’s core business is installing cladding solutions to both residential and commercial buildings, so Jenness is well aware of the benefits of James Hardie cladding products.

“Stria Cladding is easy to install and the wide panel format allows you to cover the wall height quickly,” explains Jenness.

The reclad was completed quickly in less than 140 working hours, despite the challenge of working on the second storey and off the existing roof. Cranes lifted the sheets onto the roof, and from there, the sheets were fixed to CLD® Structural Cavity Battens.

CLD Structural Cavity Battens are an alternative to traditional timber battens used with the installation of Stria and other cladding products. Due to its composition and stability, the batten acts as a structural element when fixed to the framing to deliver enhanced durability.

“Stria on a CLD Cavity system was a practical solution for this reclad project, and provides both a beautiful and durable outcome for the Council and the local community.

While Stria Cladding is well-suited to commercial applications such as this, I would definitely consider using it in my own home for a high impact modern look,” concludes Jenness.

International Best Practice – Separating the wet and dry zones in the building envelope

ARIDON1

Company: ARIDON

Uncontrolled rain water penetration remains the most fundamental threat to the structural integrity and performance of the building enclosure. The essential 4D’s of weather protection (Deflection, Drainage, Drying and Durability) need to be considered when specifying the building envelope. Claddings do the job of deflection but how good are the layers in behind the cladding at dealing with the other 3 D’s?

The Claddings Institute of New Zealand undertook a study tour in 2000 to the USA and Canada and identified the key findings:
1. http://www.cinz.org.nz/newsweathermay02.htm

  •  All buildings leak – More rain means more rain control is needed.
  • Moisture penetration is deceptive in its apparent simplicity.
  • The building envelope must have drying potential.
  • Greater building complexity leads to lower building performance.
  • The envelope is a climate transition zone that can provide ideal micro-ecological niches for destructive organisms.
  • The creation of energy efficient buildings has resulted in tight, cold and unforgiving claddings.
  • Scientific research is needed to better understand the building envelope and its role with moisture – Such understanding will eventually lead to a rational approach for the development and design of exterior wall systems.

International best practice has identified that wall constructions should be separated into the “wet zone” and the “dry zone” within the envelope. The wet zone is intended to be exposed to short and long term effects of rain water penetration and/or moisture ingress.

Think of the wet zone as two layers of defense – the cladding is like an umbrella and it blocks the majority of rain – however sometimes driving rain can get past your umbrella. This is where we need a strong second line of waterproof defense that can not only block the rain and ensure it is drained away from the frame (the dry zone) but also block the wind – as wind can drive moisture into the dry zone.

Finally a supplier has developed an exterior insulated weather-proofing wall system which suits any cladding type and provides superior protection for the frame against rain, condensation, wind and snow.

AridonB

Figure 2: SMART WALL – PANEL TOP:

Rain is deflected down the panel and out the base. Compressible ‘V-Rib’ air and moisture seals prevent moisture moving into the framing cavity.

 

The ARIDON® SMART WALL comprises rigid interlocking panels which form a continuous weather resistant shell around the building wall frame before the claddings are installed. There is no reliance on thin skins, tapes or sealants for water proofing. The SMART WALL system includes all the flashings required to provide peace of mind from external moisture problems no matter how complex the building is.

The ARIDON® SMART WALL is the solution the NZ building industry has been looking for.

AngelStep® GOLD 4 – Premium Acoustic Flooring Underlay

Advanced_Acoustics_1

Company: Advanced Acoustics

Apartment dwellers have long complained about impact noise intrusion due to footsteps and clatter of utensils and articles dropped on to the floor in apartments overhead. In addition to this impact noise, many occupants have also endured excessive airborne noise transmitted from powerful TV and audio systems.

AngelStep GOLD 4 was initially designed for use in prestige apartments, townhouses and professional office and consulting suites where discerning buyers expect performance beyond that mandated by the minimum requirements of the NZBC. Today, as occupier expectations for mitigating noise transmission have moved ahead of regulations, AngelStep GOLD 4 has found favour in the mainstream market due to the modest additional cost to achieve premium performance and peace of mind of building residents.

Field tests have achieved the ultimate 5 Star rating – streets ahead of the NZBC minimum standards. Angelstep GOLD 4 under 15mm laminated timber achieves a rating up to IIC 66 which far exceeds the standard IIC 55 required by the NZBC G6 code of compliance.

The unrivalled performance of AngelStep GOLD 4 is due to its unique construction – a resilient “cross linked” microcellular foam to form a 4 mm thick tile.

AngelStep® GOLD 4 is water resistant, suitable to combine with floor heating systems and will last the life of the building.

For more information, visit us at Buildnz at stand number 523 or contact us at www.advancedacoustics.co.nz

June Guest Article

GuestArticle_June

At Productspec we are proud to host and provide BIM data for a portion of our clients. Building Information Modelling (BIM) and the software driving this data revolution are now more accessible than ever and it is well and truly time to assess the why and how of getting involved. A question that was raised 20+ years ago with CAD but has a different answer with BIM.

Historically CAD objects were created either as 2D or 3D objects. These files were saved with a simple file name and limited referring info, UA4528.dwg or Exit Sign.dwg was anyones best guess? And in some cases numbering in the 10s or 100s of individual files representing iterations of the product. This is/was a nightmare for everyone involved, for specifiers and suppliers alike. Selecting the correct product and the file related to that product requiring blind luck or insider knowledge. And with no standard approach to govern the creation of this content there was no guarantee that they would work smoothly with other content, which often meant editing or tidying the file up before use. Often this process resulted in the architects and designers creating the objects from scratch potentially missing vital information and saving it to the office library (Door2.dwg or drawing1.dwg?). All of these steps fraught with error and peril in the search for one important piece of certainty, dimensionally accurate content.

The reasons for accurate content are obvious in the built environment. Does object X fit with object Y’s dimensions A and B? And the CAD object could answer that question. But now we have BIM; and this allows us to answer so many more questions. At Productspec we look at each product and/or range of products that requires BIM and look at the practical implications for both the specifier and manufacturer. I’d like to give you an insight into our process and approach.

We have helped our clients create BIM objects from varying levels of current information. Some have a data sheet or brochure, some just the product and others the dreaded 10s or 100s of CAD files created overseas or years ago with a short obscure file name. Thankfully computer software has advanced to allow file names longer than 9 or 11 characters! Which is a start to finding the right object, but there a more significant advancement worth mentioning. The introduction of information rich databases. Which is basically what BIM is at it’s core, a database with 2D and 3D visual representations of a building. And this is where things get really interesting.

As Chris Welch mentioned in his article in May, BIM objects can be parametric. This starts to solve the iterations of files for every product. Dimensional values are now stored and can be changed on the fly for each product of a similar grouping. This means that for many of our clients having only a handful of files that represent an entire range of objects and their dimensions and properties. This means the specifier can select the appropriate product and also have the ability to try other options or recommendations. We also have the ability to design the content to have real world limits, further driving the correct specification of products. Examples of this include limiting a product to its available sizes, like we have created for some of our piping suppliers. Or change elements in response to user inputted dimensions, as we have done many times for Holyoake and our garage door suppliers.

The next opportunity we have is to include more information or metadata. In the leading BIM software packages we can now store further information like website links, important or critical product data, SKUs or product codes, material data and so much more. Previously this detail or data that was often stored on datasheets, external documents (brochures, PDFs, etc) and your website. This required the users to search and seek out the additional data, which is made easier with both Productspec and Smartspec, but we also advise bundling this information within the content. Chris Boyle has written a great article about the metadata initiative that Productspec will continue to support and be directly involved with. At the end of the day the more we convey about a product the better informed everyone will be.

Potentially everyone has something to gain from this information. The architects and engineers already benefit by sharing their models and utilizing the information both 3D modelled and the metadata. This collaboration is now the expected norm on larger projects and will only continue to grow. And now we are seeing more and more of this sharing filtering throughout the project team; from construction, quantity surveying, the client, and right through to facilities management.

Ultimately what this has meant is that everyone expects a certain level of information about objects. Where as before generic objects may have had their place, we see the requirement of manufacturer specific information or objects to be stored in BIM. In practice this means that placeholder objects from the early design stages are replaced by manufacturer specific objects or approximations as the project develops. There are varying requirements that demand this process; from obtaining a better understanding of the design, or providing as-built information about the building for asset and facilities management.

Some practices have committed individuals to creating these objects as best they can, or just running with the out of the box content. Both situations, depending on the user, don’t provide that level of detail that is being asked for more and more. Also this content has many of the shortcomings present with the old CAD files, lack of information and potentially inaccurate dimensions. This is where we find that working closely with our clients in creating accurate and meaningful digital assets or content of their products is the best outcome.

Many of the firms I deal with on a daily basis jump on Productspec regularly to download our existing content for their current BIM projects. If you’d like to find out more about reaching this audience with information rich and accurate BIM content contact us for advice on your product. And we will work with you updating that old CAD library, distilling your datasheets into BIM, or creating new content.
