Softwall Cleanrooms, Softwall Curtains

AirBlock Benefits

AirBlock – the #1 specified curtain in the industry, offers versatility and reliability that cannot be found with any other product. AirBlock curtains can be used with framing to create a cleanroom, or also used independently within an existing cleanroom to create areas that are still cleaner. Combined with Simplex's superior mounting systems, AirBlock curtains offer increased durability and functionality. AirBlock curtains offer easier access and the best protection.

AirBlock softwalls are constructed from four-foot wide sheets of vinyl in thicknesses from 40 to 80 mil. These sheets are RF welded to form either solid walls or movable curtains. They are especially suitable for enclosing portable frame systems or improving laminar flow areas above work spaces. Softwalls are also used to further divide existing clean rooms, effectively creating cleaner inner zones.

Softwall Features Include:

Largest selection of quality materials

Simplex vinyls come in a wide array of colors, thicknesses and properties.

Mounting systems

A variety of patented mounting systems, engineered for easy installation and maximum performance.

Sealed Corners

Wraparound seals eliminate air loss or particle penetration at the corners. Our thicker vinyls require no hems or sash weights, and provide systems that are cleaner-looking, easily-adaptable and longer-lasting.


Simplex offers a variety of entry options, including hinged and sliding doors and strip doors. By alternating clear and frosted vinyl, we eliminate sticking and air gaps and make entrances easier to walk through.

RF-Welded Seams

Simplex uses RF welding on all seams and attachments. Theses seals provide a permanent bond that is cleaner and stronger than sewing. Sewing vinyl seams perforates and weakens the material, and frequent cleaning only accelerates the process. The result is premature product failure and a source of contamination.

Standard Cleanroom Grade Vinyl

All Simplex vinyls are made from pure ingredients - no recycled materials. Simplex vinyls are formulated to be fire-retardant and low-outgassing.

Thicknesses: .040, .060, .080, .120, and .160 mil.

Colors: Clear, frosted, white, amber tint, smoke tint, blue, grey, black and tan.

Reinforced Vinyl Coated Fabric

This tough, vinyl-coated polyester material is ideal for areas in your cleanroom or factory that are susceptible to frequent traffic and constant use. The vinyl is also perfectly suited for applications that require a Class 1 fire rating per ASTM E-84 flame spread and smoke test.

Thickness: 18 oz. (25 mil)

Colors: White, black, blue, grey, red, yellow and translucent frosted.

Static Dissipative Vinyl

Our ESD vinyl is built with permanent built-in inhibitors. Unlike topical coating, these inhibitors will not wear off and will last for the life of the curtain. Test result show surface resistivity of 1.8 x 1010 ohm/cm (ambient 50% R.H.) per ASTM D257.

Colors: Clear, frosted, white, black and amber tint.

Tested for Safety and Reliability

All Simplex softwall materials are fully tested. Test results are available for fire retardancy, ESD, outgassing, sound abatement, chemical resistance and light transmission.

Closure and Fastening Systems

Dual Lock Fastener

This non-particulating, clear 3M- flexible fastening system has a plasticizer-resistant adhesive and is ideal for attaching curtains vertically or horizontally to frames, hoods, benches or on overlaps.

Hook and Loop Fastener

Ideal for securing curtain overlaps. Attaches to vinyl with a plasticizer-resistant adhesive and is then sewn.

Flexible Magnet Self Closures

This quality, flexible, chemical-resistant magnet is ideal for overlapping areas where frequent access is required.

Overlap Retention Snaps

An inexpensive way of closing overlap areas of the curtains.

Lap Lock

The most recent Simplex innovation in closing systems in which opposing flaps of vinyl are RF-welded and interlock to secure panels in place.
