no more cracks or discolouration
The Evo-Blade was designed following a project meeting where an architect and contractor had specified a razor edge trim for use in both a standard plaster and acoustic plaster ceiling. The dry lining company knew it would crack their plaster, and we knew the cracking and air filtration issues it would cause to any acoustic plaster.
The Evo-Blade is designed to avoid these problems by uniquely enabling the installer to position the plasterboard in different places to accommodate different depth finishes. Unlike typical razor edge trims where cracks can develop in the skim layer of plaster or bands of discolouration caused by sudden depth changes between trim and acoustic plaster, the Evo-Blade allows plasterboard to run right up to the ceiling edge. This ensures a smooth and flawless finish every time.

All acoustic finishes are inherently air porous due to the fact they need to absorb sound. This means that when a room’s air pressure increases due to a door or window opening/closing, a gust of wind through an open aperture or a ventilation system starting up, air will be forced into an acoustic product, which over time will filter out any dust in the air.
This is not normally a problem, but when most of the acoustic ceiling is, for example, 27mm thick and the part over the razor trim is only 2mm thick, the air movement rates will be different, meaning one will change colour compared to the other over time. It’s worth noting that this can take years, but in extreme cases it can take weeks.
An incredibly versatile solution, the Evo-Blade plasterboard trim works with a variety of configurations, from regular to acoustic plaster like Oscar Elite and acoustic sprays like SonaSpray.
Oscar Evo-Blade benefits include
- Creates wafer-thin ceiling edges.
- A shallower angle means it is hidden from further back, creating an infinity edge illusion.
- Doesn’t restrict the designer to use of a particular lighting system.
- Multiple aligning slots achieve perfect corners and straight runs.
- Aluminium finish can be powder-coated in any colour.
- Does not crack or discolour ceilings like other profiles.
- Works with both acoustic and non-acoustic products for a long-lasting finish.
- Minimises shadows and reflections when used as part of a feature lighting channel.
- Designed and manufactured in Great Britain.
