Armaspray, Limpet and Spray Insulation
Understand why a spray insulation name, an installer and the original manufacturer may not be the same.
The work
Spray-applied insulation could be used on industrial equipment and structural surfaces. Workers might remember spray machinery, hoses, application crews and material preparation more readily than the brand.
Limpet and the contracting business
Court records describe Armstrong Contracting and Supply using Limpet, an English-manufactured spray insulation, before requesting an alternative product.
Armaspray production
The appellate record describes Armstrong manufacturing Armaspray in 1967–1968 for its subsidiary, with remaining inventory used in 1969. These dates are not interchangeable with Limpet’s broader history.

Start with what you remember
Remember a product, a room, a crew, an old carton or a period of work? Those details can guide a historical investigation.
