Lockdown and Sightline Control Blinds
Internal manual and motorised blinds, blackout fabrics and vision panel flaps designed to help schools and public buildings control visibility during lockdown procedures.
Practical Internal Screening for Better Preparedness
Lockdown and sightline control blinds provide a practical way to reduce visibility through internal glazed areas when privacy, screening or fast visual control is required.
For schools, colleges, public buildings and commercial premises, internal glazing can create exposed sightlines between corridors, classrooms, offices, receptions and shared spaces. Carefully specified blinds and vision panel flaps can help rooms, corridors and glazed partitions be made visually opaque quickly.
These products can support lockdown procedures and wider Martyn’s Law preparation as part of a broader safety and preparedness plan.

System Design & Applications
Internal blinds can be specified for a wide range of glazed areas, including classroom windows, corridor-facing glazing, reception screens, office partitions and internal windows.
For projects where visibility needs to be controlled quickly, internal blackout blinds or dim-out fabrics can help reduce sightlines into occupied spaces.
Vision panel flaps are designed for glazed door vision panels. They allow normal visibility during daily use and can be closed quickly during lockdown procedures to help make the room visually opaque from the corridor.
These solutions can be considered during refurbishment, retrofit, new-build specification or wider security review projects. The aim is simple: to help reduce avoidable internal sightlines and give staff clear, practical ways to control visibility when procedures require it.
Why Enviroscreen?
Enviroscreen Systems has over 30 years of experience in commercial shading, screening and tracking systems, with projects across schools, public buildings, healthcare environments and commercial premises.
You can involve us at survey, design, specification, supply or installation stage. We work with architects, specifiers, school business managers, academy trusts, estates teams, facilities managers, contractors and public-sector decision makers to help identify the right product for each opening.
Every project is assessed on its setting, glazing type, access, usage and required level of screening. That helps you avoid over-specifying while still giving staff practical tools that support lockdown procedures and wider preparedness planning.
