Sentries at Balmoral no longer have a problem with adverse weather.

A Perthshire company has delivered a second box to the estate, following the success of the initial design.

It was built using structural insulated panels (SIPs) to ensure a highly-insulated, airtight and draft-free construction.

Auchterarder-based JML Contracts provided the latest box following positive feedback from the sentries.

The new-look structure was constructed with SIPs walls and clad in timber, which is painted in green.

John Langley, director of JML Contracts, said: “This was a great commission for us, especially as a re-order, which is testament to how happy the sentries were with the first one that we produced.

“It demonstrates the flexibility of building in SIPs, allowing us to produce a bespoke construction for the Balmoral Estate.

“As a really cold part of Scotland in winter, it was also vital that it was as insulated and draft-free as possible.

“We are delighted that it has been so well received.”

The demand for SIPs is beginning to gain ground in the UK, as people begin to see the benefits that have been strongly embraced in northern Europe.

These include highly- nsulated properties which dramatically decreases heating bills, and highly engineered products which provide a greater capacity for floor and roof space.
