Shutting the sash,
made simple.

Shut the Sash Alarms keep fume hoods closed — helping labs achieve their sustainability goals, save money, and keep people safe.

Without a “shut the sash” solution, each of your fume hoods:

Consumes 3.5 homes of energy – that’s 26 tons of CO2e annually.

Wastes $1,300+ in energy every year.

Jeopardizes lab user safety.

Current solutions don’t cut it.

  • Lab user engagement programs work to an extent, but require constant communications.

  • Automatic fume hood sash closers are effective, but cost $5,500+ per hood and disrupt research both during and after installation.

  • Education and engagement efforts don’t leave lasting impacts after campaigns end.

Shut the Sash Alarms are here to help.

  • Our Alarms are behavioral change tools, providing gentle reminders to lab users that lead to good sash management habits.

    Keeping fume hoods closed when they’re not in use reduces lab user exposure to hazardous gases, and reduces energy consumption at variable air volume (VAV) hoods.

  • From energy savings alone, Shut the Sash Alarms can pay for themselves in months.

  • Many sustainability leaders are unaware of what poor sash management costs their organization in terms of dollars and cents.

    We help folks collect data that demonstrates compelling ROIs for their Green Labs efforts.

    Average energy savings of $1,100+ per hood, per year, are common.

  • No need to disrupt your organization’s research, use scarce staff time, or hire a technician to save energy!

    Shut the Sash Alarms are designed to be installed by anyone in 30 seconds–they plug into the outlet on the front of hoods and mount easily on the sash.
