01 — For energy teams

Hold setpoint with less run time

Kenfield doors form a far tighter seal than strip curtains, reducing the warm-air infiltration that forces refrigeration systems to work harder. Walk-ins hold setpoint with less compressor run time across the back of house.

The K750 Energy Door, K2 strip curtain, and K150 impact door together make a broader cold-room efficiency package for high-traffic environments.

02 — About Kenfield

Engineered for 14 years of service

30,000+ installations globally — the oldest known operating door has run continuously for 14 years. The K750's patented seals, lightweight panels, and no-finger-trap design make it the gold standard upgrade to strip curtains across grocery and food manufacturing.

03 — Why Kenfield

Engineered for the back of house

Energy Saving Door

Tighter seals and smarter door geometry reduce warm-air infiltration so walk-ins hold setpoint with less compressor run time—saving energy without sacrificing access for staff.

Patented Design

Kenfield’s patented construction balances durability with a clean, modern look that fits premium grocery environments and withstands high traffic in narrow corridors.

Flexible Solution

Lightweight panels and strong insulation make installation and maintenance more manageable while delivering the thermal performance operators expect from a top-tier energy door.

04 — Benefits

Core Benefits

Save energy by reducing infiltration

Kenfield doors form a tighter seal than strip curtains, cutting the warm-air ingress that forces refrigeration systems to work harder and run longer.
Walk-ins hold setpoint with less run time

Less warm-air ingress means compressors cycle less often, trimming refrigeration energy across cold storage.
R-7 insulation value on the K750

High insulation at the opening reduces thermal transfer where strip curtains leak the most.

The flagship energy door

The K750 is the gold-standard upgrade to strip curtains — patented seals, R-7 insulation, lightweight panels, and a no-finger-trap design that holds setpoint with less compressor run time.

Built for high-traffic grocery back-of-house: easy one-handed access for staff moving trays and stock, with durability proven over a 14-year service life.

08 — K2 Strip Curtain

Cost-effective cold-store protection

The K2 Insulated Strip Door Curtain is built for high-traffic cold storage environments — walk-in cold stores, freezers, and APV vehicles. Heavy-duty PVC strips with a thermal insulation layer form a barrier that significantly reduces warm-air ingress without impeding staff movement.

Available in a choice of colours, sign-writeable, and trimable on site to fit any opening height up to 3.5m. Top-mounted with no external frame required.
