Quonset Hut vs Nissen Hut: What Is the Difference?

Quonset huts and Nissen huts are both semi-circular corrugated steel buildings, but they have different origins and slightly different designs. If you own one in the UK, understanding the type matters for maintenance, conversion and insulation planning.

Nissen Hut (British — WWI)

The Nissen hut was invented in 1916 by Major Peter Nissen of the Royal Engineers during the First World War. It is a semi-circular structure made from corrugated iron sheets over a framework of steel ribs. Over 100,000 were produced during WWI. The design was revived during WWII when hundreds of thousands more were built across the UK for military barracks, stores and workshops. Thousands survive today on farms, industrial estates and former military sites across Britain.

Quonset Hut (American — WWII)

The quonset hut was developed in 1941 at Quonset Point Naval Air Station in Rhode Island, USA. Inspired by the British Nissen hut, the American version featured a wider profile, interior lining and different end wall construction. Over 150,000 were built during WWII and shipped worldwide. Some survive in the UK on former American military bases.

Romney Hut (British — WWII)

The Romney hut is a larger British variant developed during WWII, with a wider span and greater internal height. Romney huts were commonly used as aircraft hangars, vehicle workshops and large storage buildings. Many survive on former RAF and military sites.

Insulating Curved Steel Buildings

All three types share the same insulation challenge: the curved corrugated steel construction makes traditional insulation methods extremely difficult. Rigid boards cannot follow the curve. Spray foam is the only insulation that bonds directly to the curved corrugated profile, providing seamless thermal insulation and condensation control without framework or battening.
