WINDOW KITS

A rapid-deployed emergency replacement window system designed to restore protection, insulation, and basic livability to buildings damaged by war, disaster, or extreme weather.

Purpose-built for emergency repair

From insulation and shatter safety to self-installation and low cost, WindowKit is designed to restore protection fast in the places that need it most.

  • At a fraction of the cost of glass, V3 makes large-scale emergency repairs realistic and scalable.

  • Built from separable PET and uPVC components that can be cleaned and recycled at end of use.

  • Delivers thermal performance comparable to a double-glazed unit, helping retain heat in damaged buildings.

  • Quick to assemble, easy to install, and built to empower individuals to secure damaged homes in conflict and crisis zones.

  • Engineered to better withstand shock and debris, reducing the risk of catastrophic failure.

  • If damaged, it won’t explode into dangerous shards, helping protect occupants inside.

  • The PET panel can be replaced without rebuilding the full window system.

  • Can be opened, cleaned, dried, and reassembled to manage moisture and extend lifespan.

Product Specifications

WindowKit is a lightweight emergency replacement window system designed for rapid deployment in conflict-affected and disaster-affected buildings. The system restores thermal performance, weather protection, daylight, and occupant safety when conventional glazing is unavailable or impractical.

The system consists of a uPVC extrusion frame with dual internal glazing grooves and two independent PET glazing layers installed in parallel. Integrated gripping features within the frame create continuous perimeter retention and sealing.

Structural System

Frame: Structural-grade recyclable uPVC
Glazing: PET sheet, 0.70–0.75 mm thickness per layer
Seal: Integrated mechanical grip with no liquid sealant required

Material Composition

Assembly is tool-light and non-specialist. Four uPVC extrusion members are cut to size, after which the first and second PET panels are inserted into separate grooves. Integrated tooth features secure the glazing and form an air- and water-tight perimeter seal.

Assembly Method

The dual-layer PET configuration is designed to restore habitable indoor conditions by improving thermal insulation, reducing uncontrolled air infiltration, and preventing rain and snow ingress. Transparent glazing also restores natural daylight where board-up solutions fail.

Thermal & Environmental Performance

Unlike conventional glazing, PET is shatter-resistant and does not fail into hazardous sharp fragments. When damaged, the material is designed to deform or tear rather than explosively fragment, reducing secondary injury risk in blast-affected environments.

Impact & Safety Behavior

The system is designed for maintainability in the field. PET sheets can be replaced in situ without replacing the full frame, and the assembly can be disassembled for cleaning, drying, and moisture management. PET and uPVC components can also be separated and recycled post-use.

Serviceability & Lifecycle

Frequently Asked Questions

  • WindowKit is an emergency replacement window system designed for buildings with damaged or destroyed glazing in conflict-affected and disaster-affected environments. It is intended to restore a basic level of weather protection, insulation, daylight, and occupant safety when conventional glass replacement is not immediately possible.

  • The system consists of a structural uPVC frame and two parallel PET glazing layers. The frame is designed with dual internal glazing grooves and integrated gripping features that retain the PET sheets and create a continuous perimeter seal.

  • Yes. WindowKit is designed to be tool-light and straightforward to assemble. Frame members can be pre-cut to size or cut on-site using basic tools, while PET glazing panels slot into the grooves and are secured in place by the integrated gripping system—without the need for liquid sealants or specialist glazing equipment.

  • Unlike board-up solutions, WindowKit restores natural daylight while also improving weather protection and thermal performance. It is designed to provide a safer and more habitable temporary window replacement rather than simply closing off an opening.

  • Yes. The dual-layer PET configuration is designed to improve thermal performance and reduce uncontrolled air infiltration, helping restore more habitable indoor conditions during cold weather. The system is intended to offer insulation performance comparable to a basic double-glazed unit.

  • The system is designed to create a continuous mechanical perimeter seal that helps reduce air leakage and prevent rain or snow ingress. It does not rely on silicone or liquid sealants to achieve this.

  • It is better described as shatter-safe rather than shatterproof. PET does not fail like conventional glass. When damaged, it is designed to deform or tear rather than break into hazardous sharp fragments, reducing the risk of secondary injury.

  • Yes. One of the key advantages of the system is that the PET glazing layers can be replaced in situ without needing to discard or rebuild the full frame assembly.

  • Yes. The PET and uPVC components can be separated after use, cleaned, and recycled. This allows the system to be more maintainable and materially recoverable than many ad hoc emergency repair solutions.

  • WindowKit is designed for use across residential, medical, educational, and public buildings where glazing has been lost and a rapid temporary-to-semi-permanent replacement is needed.

  • The assembly is designed to be serviceable, allowing it to be disassembled for cleaning, drying, and moisture management where needed.
