Frameless Glass Partitions, UK-Wide
A frameless glass partition joins pane to pane with a silicone or gasket seal instead of a visible aluminium profile, so the wall reads as continuous glass rather than a series of framed panels. Weldholm builds this two ways: WH-EXPO's fully frameless structural glazing, and WH-78EI's 4mm fire-rated joint that holds an EI30/EI60 rating without a frame.
What "frameless" actually means
| Aspect | Framed construction | Frameless construction |
|---|---|---|
| Glass-to-glass joint | Visible aluminium profile holds each pane | Silicone joint or glazing gasket, no visible profile |
| Sightline | Broken into panels by the frame | Reads as one continuous surface |
Weldholm builds frameless two ways — WH-EXPO's structural glazing with invisible gaskets on both sides, and WH-78EI's 4mm silicone joint that holds a fire rating without a frame.
Where a frameless look gets specified
Anywhere the glass is meant to disappear rather than be framed:
- Reception areas and boardrooms where an unbroken glass sightline matters more than cost
- Showrooms, exhibition stands, and retail spaces built to be seen through, not framed
- Fire-compartment lines that still need to read as open, uninterrupted glazing
- Any space where a visible aluminium profile would break up the design intent
Structural glass, not glazing in a frame
WH-EXPO's tempered glass panes are structural elements in their own right, not decorative infill held inside a profile — glazing gaskets stay invisible on both sides, so nothing but glass and a hairline joint is visible. WH-78EI takes the same idea into a fire-rated wall: a 4mm joint filled with firestop intumescent material and non-flammable silicone replaces the aluminium or steel profile that most fire-rated glazing relies on, available in black, grey, or white to match the fit-out.

Frameless glazing, asked and answered
What does "frameless" mean for a glass partition?
It means panes join to each other with a silicone seal or glazing gasket instead of a visible aluminium profile, so the wall reads as one continuous glass surface rather than a series of framed panels.
Can a frameless partition still be fire-rated?
Yes — WH-78EI holds an EI30 or EI60 fire rating using a 4mm silicone joint instead of a visible frame, so a fire compartment line doesn't have to look like framed glazing.
Is WH-EXPO's glass actually structural, or is it held inside a hidden frame?
Structural. The tempered glass panes themselves carry the load, with invisible glazing gaskets on both sides — there's no hidden frame behind the glass.
What colour options exist for a frameless fire-rated joint?
Black, grey, or white, matching the WH-78EI joint options used across the rest of the range.
