Not only had Interact faced stiff opposition from the thin film alternative, it was necessary to convince the architect and main contractor that regardless of the specific testing we had carried out on solid rods (and the only company to have done so) Interact Retrofit castings met in full the standard for tension rods.
The superb, highly decorative, finish achieved using Interact’s casting system also means that there is no requirement for overcoating every three to five years as is the case for thin film intumescent coatings (where failure to comply may compromise the warranty of the fire protection).
Interact’s warranty is standard at 25 years to first maintenance. Intermittent decorative coatings do not compromise the warranty issue.
A quick walk over the road to another building (a local mixed-use retail and hotel complex) demonstrates the risk in using thin film as shown in the external coating. Interact’s system of casting provides reassurance both internally and externally regardless of the environmental conditions. Epoxy castings by Interact are certified to the environmental standard C5.
