Drywall Installers: How the DeltaSuit is a Game Changer
Drywallers are among the workers most exposed to shoulder injuries. Discover how the DeltaSuit reduces muscle fatigue.
Ask any drywaller what hurts at the end of the day. The answer is always the same: their shoulders.
This is not a coincidence. It is the mechanics of the trade. Installing panels on the ceiling, screwing overhead, holding a sheet at arm's length while a colleague fastens it—these actions are repeated hundreds of times a day, often during eight to ten-hour shifts. Over time, the shoulders, neck, and upper back absorb cumulative stress that inevitably leads to musculoskeletal disorders (MSDs).
35% of drywall installation workers complain of shoulder pain. This figure surprises no one in the trade, but it should alert employers and health and safety managers.
The specific problem of drywallers
Unlike other construction trades, drywallers work in a particularly restrictive position: their arms raised above their heads, often extended, with a constant load.
When you hold a 25 kg drywall sheet against a ceiling while fastening it, your shoulders do intense static work—the worst type of effort for muscles. No movement, no recovery. Just a sustained contraction, over and over again.
It is precisely these static and repetitive efforts that cause:
Rotator cuff tendinitis
Inflammatory shoulder bursitis
Chronic neck and trapezius pain
Prolonged sick leave and, sometimes, premature career endings
For an employer, each WSIB/CNESST claim related to shoulders represents weeks of absence, a replacement that is difficult to find, and lost field expertise.
What the DeltaSuit does
The DeltaSuit is a passive shoulder exoskeleton developed by Auxivo and distributed in Canada by Exosquelettes Canada. Passive means it has no motor, battery, or electronics. It works using integrated elastic elements that store the energy from the downward movements of the arms to restore it during upward movements.
In simple terms: when the installer raises their arms to the ceiling, the exoskeleton helps. When they lower them, it recharges. It is a continuous, discreet, and completely autonomous mechanical system.
The numbers that matter
Up to 65% reduction in muscle activity in the shoulders and neck, measured in real-world conditions
2 adjustable assistance levels: 5.2 Nm for moderate tasks, 6.6 Nm for more demanding work
Only 2.15 to 2.25 kg, the worker practically does not notice the weight of the device
Two sizes available (S/M and L/XL) to adapt to different body shapes
What it changes on the job site
At the end of a shift, workers wearing the DeltaSuit report significantly less muscle fatigue in their shoulders. On high-volume panel days, such as ceilings of an entire floor, the difference becomes particularly noticeable.
Maintenance is also designed for job site reality: the technical textiles are machine washable, which avoids hygiene problems when shared among teams.
"Can we work normally with this?"
This is the first question drywallers ask, and it is the right one.
The short answer: yes. The DeltaSuit is designed for working at heights, not for restricting movement. It does not interfere with panel installation, screwing, or moving around the job site. The worker maintains complete freedom of movement; it is only when raising the arms that the support activates.
It is not a cumbersome piece of equipment to avoid. It is PPE like any other that you put on in the morning and take off at the end of the day.
The calculation that adds up
A DeltaSuit costs about $3,000 to $4,000. A workers' compensation claim for a shoulder injury (surgery, benefits, replacement) can easily reach $20,000 to $50,000, not to mention the impact on the team and productivity.
For an employer with two or three drywallers on an intensive site, a single prevented incident offsets the cost of the entire program.
And beyond the financial calculation: workers ending their careers with their shoulders intact is a possible reality. Not a luxury.
Who is the DeltaSuit the right choice for?
The DeltaSuit is particularly suitable if your drywallers:
Regularly work on ceilings or high walls
Work shifts of 8 hours or more with their arms raised
Have already experienced episodes of shoulder or neck pain
Are approaching mid-career and looking to extend their longevity at work
It is less suitable for work exclusively at low wall heights, where the shoulders are not particularly strained.

Because a drywaller with healthy shoulders is a drywaller who will still be there in ten years.
