Strip Curtains: Small Upgrade, Real Savings

If you operate a restaurant, grocery store, or any facility with walk-in refrigeration, you already know that coolers and freezers are among your largest energy users. What’s less obvious is how much energy is lost every time a walk-in door is opened—even for a few seconds.
That’s where strip curtains come in. They’re simple, inexpensive, and backed by real utility data showing measurable energy savings.
The Hidden Cost of an Open Walk-In Door
Every time a walk-in door opens, warm, humid air rushes in and refrigerated air spills out. The refrigeration system then has to work harder to pull temperatures back down.
In real facilities, this happens constantly:
Walk-in doors opening dozens of times per shift
Doors held open during restocking or prep
High traffic during lunch, dinner, or delivery windows
Without a barrier in place, your refrigeration system ends up conditioning the kitchen or storage area instead of just the cooler. That means higher energy bills, more compressor run time, and faster equipment wear.
How Strip Curtains Solve the Problem
Strip curtains are overlapping, flexible PVC strips installed inside the walk-in doorway. They allow staff and carts to pass through easily while dramatically reducing air exchange.
Key benefits:
Reduced warm air infiltration every time the door opens
Immediate re-sealing after someone passes through
Hands-free operation for busy staff
Clear visibility to improve safety
No impact on workflow, even in high-traffic areas
In short, strip curtains keep conditioned air where it belongs—inside the walk-in.
Energy Savings Backed by Utility Data
These savings aren’t theoretical. Southern California Edison has conducted field studies measuring actual energy savings from strip curtains across restaurants, supermarkets, convenience stores, and refrigerated warehouses.
Typical annual energy savings per square foot of door opening include:
Restaurant coolers: ~18 kWh/ft²
Restaurant freezers: ~77 kWh/ft²
Supermarket coolers: ~159 kWh/ft²
Supermarket freezers: ~409 kWh/ft²
With Bay Area electricity rates around $0.38/kWh, even small doors can deliver meaningful dollar savings—especially for freezers.
What Does That Mean in Real Dollars?
For a standard 3’ × 7’ walk-in door:
Cooler: roughly $140/year in energy savings
Freezer: roughly $600/year in energy savings
Typical installed cost:
Cooler strip curtains: ~$200 installed
Freezer strip curtains: ~$220 installed
That puts payback anywhere from a few months to under a year, depending on usage and application. Freezers and high-traffic doors almost always deliver the fastest ROI.
Benefits Beyond Energy Savings
Energy savings alone justify strip curtains, but they also deliver additional operational benefits:
More stable temperatures, supporting food safety
Reduced frost and condensation, lowering slip hazards
Less compressor cycling, extending equipment life
Reduced wear on door gaskets and hinges
Faster staff movement with fewer propped doors
These secondary benefits reduce maintenance costs and help avoid downtime.
Choosing the Right Strip Curtains
Not all strip curtains are the same. Performance depends on proper selection and installation:
Food-grade, cold-rated PVC that stays flexible
Proper strip width based on foot traffic or carts
Adequate overlap (typically ~50%) to eliminate gaps
Full coverage of the opening, edge to edge
Poorly sized or installed curtains don’t deliver full savings—and often get pushed aside or removed by staff.
Professional Installation Matters
At Bay Area Gasket Guy, we handle everything on site:
Precise measurement of your door opening
Correct strip material and width for your application
Proper mounting to ensure full coverage and longevity
Fast installation with no operational downtime
Many customers bundle strip curtains with gasket replacement or other preventive maintenance to maximize efficiency in a single visit.
The Bottom Line
Strip curtains are one of the simplest, lowest-cost energy upgrades you can make to a walk-in cooler or freezer—and the savings are backed by utility-verified data.
Your equipment runs less. Your energy bills go down. Your staff moves faster. And your refrigeration lasts longer.
With energy costs continuing to rise, it’s an upgrade that starts paying for itself almost immediately.
