Tips for Glazing a Vinyl Sash

Since most of the hard work was done getting the old glass out, putting in the new glass is fairly straightforward, however there are a couple things to keep in mind.

  • There may still be remnants of existing sealant on the sash after removing the old glass unit. Make sure to use turpentine or lacquer thinner to clean the area where the new glass will be installed
  • Unless the pre-existing set blocks are in amazing shape, replacing them will help keep the insulated¬†¬†unit secure.
  • If you’re not going back in with double-faced glazing tape, silicone is the preferred sealant.
  • The same gap should exist between the new glass and sash as the old one, however 1/8″ should be acceptable for any expansion or contraction that may occur
  • Take care when re-installing the glazing beads. Those are not generic parts.
