Insulate Ukraine Emergency Window V2 installed in a war-damaged building

Emergency replacement window system

Emergency Window V2

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

Designed for rapid post-strike repair, V2 enables our local builder teams to quickly measure, cut, and install emergency replacement windows where homes and buildings have been damaged.

Response V2

Built for humanitarian-led emergency repair

Designed for rapid post-strike repair, V2 enables our local builder teams to quickly measure, cut, and install emergency replacement windows where homes and buildings have been damaged.

Insulating

Designed to improve insulation and reduce heat loss in damaged buildings where conventional glazing is unavailable.

High impact resistance

PET glazing is designed to better withstand everyday impact, debris, and post-blast damage than conventional glass.

Shatter-safe

If damaged, PET is designed to deform or tear rather than shatter into dangerous sharp fragments, helping reduce injury risk.

Weatherproof

Designed to improve weather sealing, helping reduce drafts, rain ingress, and further exposure after window damage.

Affordable

Designed to keep emergency window repair low-cost and scalable, making rapid replacement more feasible at large scale.

Recyclable

Built from recyclable wood and PET components that can be repaired, replaced, or recycled at end of use.

Designed for rapid local installation

Built and installed by trained local teams

V2 is installed by trained local teams who measure each opening and build the window on-site.

Product specifications

How V2 is built and performs

V2 is a lightweight emergency replacement window system designed for rapid post-strike deployment by local installation teams in conflict-affected and disaster-damaged buildings.

Structural system

Frame: Engineered softwood, cut and assembled on-site
Glazing: Twin-sheet PET
PET thickness: Approx. 500 microns per sheet
Fixing method: Staples or equivalent fixings and glazing bead
Seal: Industrial-grade adhesive tape and perimeter silicone

Material composition

The system consists of a locally cut and assembled engineered softwood frame fitted with a double-layer PET glazing configuration. Two PET sheets are fixed to the frame to create an insulating air gap.

Assembly method

The system is designed for rapid on-site fabrication and installation by trained local teams. Timber components are cut and assembled in the field, after which PET glazing sheets are fixed into place.

Thermal and environmental performance

The double-layer PET design is intended to restore basic thermal insulation, weather protection, and natural daylight in damaged buildings, helping reduce drafts, uncontrolled air infiltration, and exposure to rain or snow.

Impact and safety behaviour

Unlike conventional glass, PET is shatter-resistant and does not break into dangerous sharp fragments. When damaged, it is more likely to deform or tear rather than explosively shatter.

Serviceability and lifecycle

PET sheets can be replaced on-site if damaged, while the timber frame can be adapted or rebuilt as needed. Both wood and PET components are recyclable.

Technical and practical questions

Frequently asked questions

What is our window designed for?

V2 is an emergency replacement window system designed for buildings with shattered or destroyed glazing in conflict-affected and disaster-affected environments. It is intended to quickly restore basic weather protection, insulation, daylight, and occupant safety when conventional glass replacement is not immediately possible.

What is the system made from?

The V2 system consists of a locally cut and assembled engineered softwood frame with two layers of PET glazing. The PET sheets are fixed to the frame using staples or equivalent fixings, with adhesive tape and perimeter silicone used to improve sealing and insulation.

How is it installed?

V2 is installed by trained local teams who measure each opening and build the window on-site. The timber frame is cut and assembled, PET glazing is fixed to the frame, and the completed unit is then installed and sealed into the opening to restore protection after a strike.

Is it easy to assemble and install?

V2 is designed for rapid on-site assembly and installation by trained local teams. Timber components are measured, cut, and assembled in the field, then fitted with PET glazing to create a lightweight emergency replacement window that can be installed quickly after a strike.

How does it compare to boarding up a window with plywood or OSB?

Unlike boarded-up windows, V2 helps keep homes brighter, warmer, and more protected after damage. It is designed to restore a basic level of comfort and safety rather than simply closing off the opening.

Does it keep buildings warm?

Yes. V2 is designed to improve insulation and reduce drafts, helping damaged buildings retain more heat and remain more habitable in cold conditions.

Is it waterproof and airtight?

The system is designed to provide basic weather sealing by helping reduce drafts and limit rain or snow ingress after window damage. In V2, this is achieved using perimeter sealing methods including industrial-grade adhesive tape and silicone to improve protection and insulation.

Is it shatterproof?

Unlike conventional glass, PET is designed to deform or tear when damaged rather than break into dangerous sharp fragments, helping reduce the risk of secondary injury.

Can the materials be recycled?

Yes. The main materials used in V2 (PET and wood) are recyclable, helping reduce waste at end of use where appropriate recycling streams are available.

What kinds of buildings can it be used in?

V2 can be used in a wide range of buildings affected by window damage, including homes, apartment blocks, schools, medical facilities, and public buildings where rapid window replacement is needed.
