Emergency replacement window system
WindowKits Volya
Designed for direct distribution and flexible installation
WindowKits Volya is a transparent, insulating and shatter-safe emergency replacement window system that can be installed by individuals, local partners or Insulate Ukraine teams.
Why Volya exists
Not every community can wait for a trained installation team
Volya was developed for situations where direct distribution is more practical than sending a trained team to measure and install every window individually.
Designed for distribution
The system can be prepared centrally, transported efficiently and delivered directly to the people or organisations who will install it.
Flexible installation
Volya can be installed individually, by local partners or by Insulate Ukraine teams, depending on the operating conditions.
Built for changing conditions
The delivery model can adapt when security risks, access, supply chains or local capacity change during war and other crises.
WindowKits Volya
Purpose-built for emergency repair
From insulation and shatter safety to self-installation and low cost, WindowKits Volya is designed to restore protection fast in the places that need it most.
Affordable
At a fraction of the cost of glass, WindowKits Volya makes large-scale emergency repairs realistic and scalable.
Recyclable
Built from separable PET and uPVC components that can be cleaned and recycled at end of use.
Insulating
Delivers thermal performance comparable to a double-glazed unit, helping retain heat in damaged buildings.
Self-install
Quick to assemble, easy to install, and built to empower individuals to secure damaged homes in conflict and crisis zones.
High impact resistance
Engineered to better withstand shock and debris, reducing the risk of catastrophic failure.
Shatter-safe
If damaged, it won’t explode into dangerous shards, helping protect occupants inside.
Maintainable
The PET panel can be replaced without rebuilding the full window system.
Serviceable
Can be opened, cleaned, dried, and reassembled to manage moisture and extend lifespan.
Designed for simple assembly
How Volya is assembled
Engineered for simple, intuitive assembly, allowing rapid installation in the field without complex tools or specialist teams.
-
01Prepare the frame members
Four uPVC extrusion members are pre-cut to size or cut on-site using basic tools.
-
02Insert the first PET panel
The first PET glazing panel is inserted into one of the frame’s internal glazing grooves.
-
03Insert the second PET panel
The second PET panel is inserted into the parallel groove to create the dual-layer glazing system.
-
04Secure the assembly
Integrated gripping teeth retain the PET panels and create a continuous perimeter seal without liquid sealant.
Engineering overview
How the system is built and performs
WindowKits Volya 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.
Structural system
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.
Material composition
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
Assembly method
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.
Thermal and environmental performance
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.
Impact and safety behaviour
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.
Serviceability and lifecycle
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.
Technical and practical questions
Frequently asked questions
What is WindowKits Volya designed for?
WindowKits Volya 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.
What is the system made from?
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.
Is it easy to assemble and install?
Yes. WindowKits Volya 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.
How does it compare to boarding up a window with plywood or OSB?
Unlike board-up solutions, WindowKits Volya 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.
Does it keep buildings warm?
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.
Is it waterproof and airtight?
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.
Is it shatterproof?
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.
Can damaged glazing be replaced without replacing the full unit?
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.
Can the materials be recycled?
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.
What kinds of buildings can it be used in?
WindowKits Volya 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.
How do you clean the units?
The assembly is designed to be serviceable, allowing it to be disassembled for cleaning, drying, and moisture management where needed.
