Bradford Insulation has recently launched the new Ashgrid Spacer for commercial metal roofs, allowing building contractors to meet the latest BCA (Building Code of Australia) requirements, which became effective as of May 2009, without compromising the roof system or reducing productivity of installation.
In the past it was typical to install insulation in commercial metal roofs directly under the metal roofing, but this resulted in the insulation being compressed between the roof and the purlins.
While safety wire mesh was allowed to sag in between the purlins to help the insulation to recover to its full size, this practice was not seen as ideal by WorkCover NSW from a safety point of view.
The BCA then introduced Energy Efficiency provisions under Section J, which insisted on minimum R values (effectiveness measure of insulation) to maximize thermal comfort and the energy efficiencies of the buildings. To meet these new criteria adequate space had to be created above the purlin line for the insulation blanket to recover to its full nominal thickness.
Bradford Insulation’s Ashgrid Spacer has solved this problem while allowing for fast and secure installation that is compatible with both pierce fixed and conceal fixed roofing systems without the need for endcaps or plugs.
This new Ashgrid Spacer system is delivered pre-assembled to the site for simple installation and consists of a bar and two supporting brackets, which can be easily repositioned to suit fittings. Ashgrid brackets are 80mm high to allowinsulation to recover to its full design thickness.
The system uses an innovative Safe-Loc feature to prevent bars from separating providing stability and piece of mind at the click of a tab.
Roger Pecnik, Bradford Commercial Marketing Manager, said he couldn’t be happier that Bradford Insulation has brought Ashgrid Spacer to the Australian market, with success already proven in Europe where it has been used extensively.
“The Ashgrid Spacer requires no need to change the method of fixing roof panels and accredited testing and extensive use proves it does not diminish the performance of roofing systems,” said Roger.
