One of Gentle Giant's most popular albums (although the band themselves were not happy with it at the time, being made under pressure of Phil Shulman's departure), it was available in North America only as a rare import – both LP and CD – until 2004 when a digitally remastered CD was released. This was because their US label Columbia Records rejected the album as uncommercial. As a result Columbia dropped the band from the label which contractually allowed the band to take ownership of the original master recording and all rights to it. This cleared the way for the first "official" release of the title in the United States on compact disc on the band's own Alucard label. It is the first Gentle Giant album after the departure of Phil Shulman.
The 2004 release had two live recordings from the tour as bonus tracks. The album was reissued in 2005 and distributed by Derek Shulman's DRT label with 1 bonus live track as part of the 35th Anniversary reissue series of the band's back catalogue. In 2009 "In a Glass House" became available for the first time as a digital download with bonus live recordings (these recordings differed from the original 2004 and 2005 release of the album) remastered by Fred Kervorkian under the supervision of Ray Shulman. In a Glass House received a physical release on CD as part of a 40th Anniversary series of reissues this time without any bonus tracks with plans to release vinyl versions of all the band's albums from In a Glass House through Giant for a Day in late 2010.
The album is allegedly based around the concept that "people who live in glass houses shouldn't throw stones". The record begins and ends with the sound of breaking glass.
The final track of the album is hidden. Following the song "In a Glass House", there is a delay then a brief recapitulation of every other track on the album. The album cover had a black and white lithograph of the group covered with clear plastic ("glass") on a die-cut.
