Heavy Glass Installation
Robust glass solutions for high-demand architectural applications.
Some projects need more than a window. Heavy glass — 3/8", 1/2", 3/4" and thicker tempered or laminated panels — is what you use for frameless shower enclosures, glass railings, structural glass walls, large storefront lites and oversized doors.
RPM Glass has the lifting equipment, vacuum cups and crew to move and set oversized and heavy glass safely, from a 500 lb lobby lite to a full run of frameless deck railing. We fabricate with polished edges, notches, holes and cutouts to match your hardware.
Heavy glass is also the backbone of frameless shower doors and glass railing systems for residential projects — one of the most requested upgrades from homeowners across MetroWest and Worcester County.
What's included

Frequently asked questions
How thick does railing glass need to be?
Most residential railings use 1/2" tempered or laminated glass; commercial guardrails often require laminated tempered glass per code. We size it to the application and local code.
Do you install frameless shower doors?
Yes — measured, fabricated and installed with polished hinges, clamps and header options.
