There are a number of key changes to insulated panel design from CCB to LLD
For Bondor panels we are utilising Bondors fixing method
CCB uses pan fix methods
LLD uses Bondor recommended fixing method
Non Cyclonic is rib fixed
Cyclonic is rib and pan fixed
Gable Structures
CCB uses the top skin as support and the insulation and ceiling are inside the beam, sheet overhang is not possible.
LLD the ceiling sheet sits on top of the beam and the sheet can extend past the beam for an overhang
Bondor Solarspan and Insuroof spans have changed to meet the new NCC requirements. As part of this change, LLD will show the allowable span for
a. Wind Classification Single Span
b. Wind Pressure Single Span
c. Wind Pressure Double Span
For the selected roof sheet, LLD will use the optimum single span, if this span is not suitable for the frame width , LLD will add a purlin and use the Double span data.
If LLD inserts multiple purlins then you will need to change your roof sheet to accommodate double or single span or adjust your design. LLD cannot provide Engineering for Multispan.
4. Panel Thicknesses
a. LLD has more available panel thicknesses than CCB to choose from
i. For Non Cyclonic , up to 200mm
ii. For Cyclonic up to 150mm
