STORY: Ukrainian pensioner Tetiana Beibyko is happy about her new windows.

"This is great, it is brilliant!"

"There is no draft, no blast of air. Before it was all shattered, there was a hole here."

Since Russia's invasion in 2022, many Ukrainians living near the front have had to contend with smashed windows, in a country with often brutal winters.

Now a small non-profit group is stepping in to help them replace shattered panes with cheap triple-layer ones made of polyethylene sheets.

In the Donetsk region, workers from the group Insulate Ukraine are installing pre-made windows in bomb-damaged buildings just 30 miles from the front line.

The group says their windows are designed to withstand a blast wave.

It claims they also insulate better than makeshift solutions from residents, and make winter survivable.

So far, the group's worked on over 4,000 homes.

Founder Harry Blakiston Houston first visited Ukraine in 2022.

The Northern Irish man spent six months developing a product that could make war-torn areas liveable for those who remain.

"We've seen buildings with windows shattered from the beginning of the war, they still haven't been touched. There are still millions of windows left to do."

"The frontline is dependent on these civilian areas for the postal services, doctors' surgeries, shops. It is really important to keep these towns going and give them a future and I think that's what we can help with."

Houston says residents near the front line need to queue for months for imported glass.

And while full compensation for damaged buildings requires time and funding from institutional donors, the group's windows are made of readily available PVC piping and polyethylene.
