The new version fixes up a few bugs that have been detected over the last month or so:
Fix problem that you could not alter thickness of cavity infill
Fix problem with copy and pasting results.
Copy illustration now saves the picture/illustration to a file in the users Appdata folder
Fixed illustration where cavity absorber is vertical instead of horizontal
Fixed problem with SonArchitect export
Fixed problem with adding porous absorber to ISPL and rain noise calcs
Fixed problem with floor cover selection for light weight constructions
Improved combo box selection functions in Materials Editors
Updating chart legends for rain noise and ISPL calculations
Updated description for Floor constructions, so the floor cover is listed first
added CDM HR 50 flaoting floor and some AcoustiCork floor underlays
CertainTeed materials modified Young’s Modulus for some boards

* Re-worked Glazing algorithms to try and get the best empirical match between available data and INSUL * Add 0.75mm BMT steel studs * Beginnings of Chinese Translation (early days) * Adding joist and stud dimensions to print outs * Fixing bugs with entering cavity dimensions * Minor additions to the Materials database * Updated calculations for leak predictions * Fixed minor bugs on Leaks tabs * Added leak details to printouts * Improved reliability of filtering functions in the Materials Editor * Updated string handling in search boxes to manage empty strings * Fixed an open-file bug which occured when using comma as the decimal separator * Updated rating methods for rain noise calculations * Fixed printing bug (no construction details printed, only leak stuff)

New! New features in Iris

IRIS currently allows consultants to accurately measure a range of acoustic parameters including many which have traditionally been very difficult to obtain, such as lateral fraction. Recently, our development team has been working behind the scenes to expanding IRIS’s toolbox even further.

The latest version is nearly complete and new features will allow users to measure intelligibility metrics.

New IRIS tools will measure:

• speech intelligibility (STI according to IEC 60268-11 Ed. 4)
• spatial decay rate (D_2,S)
• level of speech at 4 m from source (L_p,A,S,4m)
• distraction distance (r_d)
• privacy distance (r_p)
• VDI 2569 room acoustic class

These new metrics are calculated according to procedures detailed in two recently published office acoustics standards, ISO 3382-3:2012 Acoustics — Measurement of room acoustic parameters — Part 3: Open plan offices and VDI 2569:2016-02-Draft Sound protection and acoustical design in offices.

We have just released the latest update of INSUL. This can be downloaded and installed using the “check for updates” feature in the About screen. Or downloaded and installed from this link http://www.insul.co.nz/media/31135/Update90r08.exe The list of new features and bug fixes is as follows: Release 9.0.8 February 2018 * Added some decimal places to English units display. * fixed crashing when selecting Mini-orb roofing * In Outdoor to Indoor calculator fixed mucked up grid when switching between octave and 1/3 octave * Added 28mm Furring Channel (Australian and New Zealand connections lists) * fixed problem in SonArchitect export for glazing * Added Israel as a region * add check box to force cavity width to remain constant (stud sizes adjust to maintain cavity width) * Partition dimensions now showing in OSX * Altered colour of buttons etc to make selections easier to see * improvements to Glazing section (add check box for timber sash windows, improved triple glazing algorithms for normal aluminium frames) * Added CertainTeed materials * Made most woods orthotropic. * Printing function added to the Materials Editor * Undo and Redo functions added to the Materials Editor * Undo and Redo functions added to the Composite TL Calculator * Added an underlay selection box to the Materials Editor Floor Covers tab * Updated Composite TL Calculator to better handle very small element areas * ‘All regions’ searching option added to the Materials Editor search window * Revised styling for buttoms on the main INSUL window, including options in the View menu to change Style and layout * Revised styling for the Materials Editor search window, using expander lists * Updating Materials Editor form size for improved display on Surface Pros * Add STC/Rw single panel rating to Properties display. * Can now select and show a frame for a single panel, useful for getting the illustration more correct in some situations * As a consequence of last item we have changed the way you add a porous facing, now added in Frame 1 (no longer on the porous page).

Hopefully got on top of printing issues (previously only 600 dpi really worked properly) * Add Cold formed steel joists as option for ceilings and floors * Add load bearing steel studs with resilient rail (1.0-1.6mm or 20g to 16g) * Add prediction of impact sound for plastic foam underlays. * Fix incorrect addition of impact sound levels for octave band display * Re-instate transmission loss for specific angles of incidence for free field on source side * re-enable display and entry of dynamic stiffness (metric units only) * added panel information to 2D display * Fixed illustration of batten and cradle spacing for 400mm etc * minor translation fixes * added margin of error to printout * correctly set, and store and recall setting of frequency ranges for C and Ci * increase length of project number and name * fix problems in SONarchitect export of floors (not export airborne and impact at the same time) * added EVA as a glazing interlayer option * added GTEC resilient acoustic stud as a frame option * many small improvements to the French translation * beginnings of Polish and Chinese translations * fix bug in Impulse reponse generator in Auralisation (didn’t affect the main auralisation part) * fix bugs in English units for surface mass dimensioning of glazing constructions

Insul version 9.0 

Marshall Day Acoustics are delighted to announce the release of version 9.0 of INSUL.

This new version presents a major over haul of the user interface to provide a new foundation for the next 10 years development of this world leading software.  The most obvious feature to the thousands of INSUL users will be the 3 D illustration of the partition to be calculated.  This can be rotated, zoomed and an X ray view displayed.  This makes the communication with an end user of the calculations easier and provides a degree of confidence that the prediction is based on the users actual partition design.  A trial version can be downloaded from the download page on this website and a trial key obtained from your local distributor.

A short list of new features compared to version 8

• New user interface design with 3 D illustration of the construction that can be zoomed and rotated.
• Better utilisation of small or big screens. (Elements of interface can be re-arranged for personal preference)
• Prediction of floating floors using polystyrene or mineral wool with concrete screed on top.
• Double absorptive blankets can be selected (means illustrations can be more realistic)
• Prediction of external cladding systems using PIR or Polystyrene insulation
• Better auralisation with a user expandable library of sounds.  Ability to record auralisations for later replay without INSUL
• New types of connections and improved illustrations
• Thermal insulation of glazing (according to EN 673)
• Database of steel or timber studs (standard sizes selected from menu).
• Pitched roofs can now be predicted
• Multi-platform (Windows, Apple Mac Os) (this may be a couple of months away)
• Better search through materials files.
• Filtering lists by category or manufacturer.
• New types of frames/connections such as Batten and Cradle isolation pads
• Add copy and paste functions to composite TL calculator, and to outdoor-indoor calculator (so you can transfer results).
