Three local Gisborne Schools have recently undergone a much-needed retrofit of their older kit-set classrooms as part of the Ministry of Education’s Modern Learning Environment programme. This project was initiated when it was identified that these types of buildings had potential structural failings, and an upgrade of the structural integrity would extend the building life a further 20 years. A requirement of this project was for the building envelope to be left uninterrupted, while the thermal and acoustic properties were refreshed. Property services group, School Support Limited, took on this challenge and were very pleased with the finished results.

 

Solution - Product & Installation

With more than 600 of these traditional prefabricated classrooms in the Hawkes Bay/Poverty Bay region, Gisborne Central School, Tiniroto Primary School, and Ohuka Primary School were lucky to receive the first round of upgrades.

Developing the existing classrooms to extend their building life was considered highly cost-effective, compared to building a new classroom. As the buildings had no external building paper or insulation, encapsulating or insulating walls internally was not an option – prompting School Support Ltd to seek out an alternative solution.

Aware of the high performing acoustic properties of 50mm Quietspace® Panel, Project Manager Phil Elms was pleased to learn that it also achieves an R-value rating of R1.48. While enjoying the acoustic benefits of Quietspace Panel, the thermal properties have helped lift the total performance of the building envelope. Custom cut and slotted into aluminium joists, the Quietspace Panels laminated with Atlantis coloured Vertiface provided a great cost-effective solution for the building retrofits.

Autex Products

Other products used in the project were Autex Composition® acoustic fabric and GreenStuf® polyester insulation. Koala coloured Composition was used to transform walls between classrooms into acoustic notice boards, increasing overall acoustic performance and reducing noise bleed. Made from 100% polyester fibre, Composition won’t stain, rot, or break down, making it a safe, non-toxic, long-lasting and sustainable acoustic wall treatment.

To complement the thermal performance of the 50mm Quietspace Panel, the R3.6 rated GreenStuf insulation was installed into the ceiling space. Not only was GreenStuf in roll form easy to install because it was pre-cut to joist widths, it also requires no safety gear because of the non-toxic nature of polyester insulation.  This was a deciding factor when installing GreenStuf as its non-toxic, non-irritant attributes make it a safe choice for young children who could be exposed to airborne particles. GreenStuf is the only insulation accepted into Asthma New Zealand’s Breath Easy programme as a product considered safer for New Zealanders living with asthma.

 

Benefits & Feedback

Teachers had nothing but positive feedback on their freshly renovated teaching environments and believe that all schools would benefit from the upgrade. Prior to installation, several teachers commented on how cold the classrooms were – especially in the mornings – and how easily students were distracted by both internal and external sources of noise. Now, classrooms are warm and cosy and there is no longer a need to turn on heat pumps – which will be very cost effective in the long term. Teachers also loved the finished look of the classrooms – in particular the colours and the overall calming effects the retrofitted rooms evoked.

 

Future Projects

Due to the complete success of the trial upgrade, future projects are in the pipeline with the next stage set to kick off in October 2015.

All students deserve to learn in a warm, calm, and nurturing environment. Autex is looking forward to working with School Support Ltd on future retrofit classroom projects.
