New release (8.0.4)
14 May 2015
The new release has been put online today (14 May 2015). There are a number of bug fixes and minor improvements. The main improvements are as follows:
- Added new “double masonry” connection type to model double masonry walls tested in laboratories where there is a small trace of flanking. Note this may over predict results from older laboratories where the two masonry walls are not so well isolated from each other.
- Fixed small non-reciprocity for non-symmetrical lining of timber stud walls.
- Restored some missing materials
- Minor changes to printouts of ceilings and floors
- Outdoor to indoor calc page can now be open at the same time as the main INSUL window
- Added some Porotherm Bricks, and Austral Verticore bricks
- Tidied up Fletcher Insulation absorption products
- Added a new connection “Steel spring hanger” to model a ceiling hung via steel hangers such as Mason W30 , or Kinetics ICC-50.
- The illustration for timber joists can be changed amongst 4 different possibilities (calculation is unchanged, just the picture)
- Added new joist option (resilient strip or batten on top of joist, with resilient rail underneath). This is modelled on the James Hardie QStrip.
- Previously one could have a different absorber in a wall cavity to a ceiling cavity, so if you switched between wall and ceiling the absorber changed. I decided this was confusing and so now the absorber is the same.
- Added overall D2m,nT to Outdoor to Indoor calculation display.
- Added ability to calculate and display the difference between two R or Ln spectra (see “Table” page). Changed the behaviour of the “Set Comparison” buttons (and replicated them on the table page).
- Replaced “Set Reference” check boxes with buttons above the relevant columns on the table.
- Ctrl C and V work in the table page as per usual Windows behaviour (sorry it’s taken so long)
- Fixed some translation issues, (improved layout, but some translations still to catch up with sorry)
- After extensive comparisons between lab data and predictions we have increased the low frequency cavity damping by 35%. This reduces the depth of the low frequency dip.
- Minor change to cavity damping for double glazed windows that use laminated glass.
- Fixed bug where changing insulation in floor cavity did not get changed in the “Description” tab.
- Added search/filter function for cavity insulation, can search on fragment of text in the absorber description
- Added the variable Impact anisotropy for Impact Sound Pressure Level (ISPL)calculations, which supersedes an empirical correction in previous Insul versions and is particularly relevant for light weight timber flooring
- Fixed minor bugs for floor cover calculations, associated with updating predictions to reflect changes in damping and other variables
- added a calculator flow resistivity to Absorber properties form
- changes to Ortech properties
- changed Nuralite roof properties in New Zealand materials file
- added Lexan (Polycarbonate)
- updated CSR Boral materials and also Boral materials list
