Yes absolutely! The surface area of the uneven sections will dictate which option is the most cost-effective. Sometimes clients have old buildings where the ceilings are just not that level, typically we will measure the panels of glass individually and allow for the discrepancies in height. Alternatively, we will install a deeper perimeter channel that holds the glass as this will absorb the undulations of an older ceiling. During a phonecall/survey our team can talk you through the options.
Often modern offices have services exposed on the ceilings, these can be cables for lighting or larger services such as air conditioning units. Typically in these instances, a drywall bulkhead is built to consume the service, the glass is then joined against the level underside of the bulkhead.
