Panels & Systems

Our ULTIMA range of spandrel panels are engineered so that each layer of the panel’s composition works together to produce a spandrel with outstanding mechanical properties, thermal efficiency and durability.

The ULTIMA panel is available in five different variants, each of which can be constructed to achieve either an A1 or A2-s1,d0 fire classification to BS EN 13501-1. ULTIMA panels have been rigorously tested for both fire and structural performance making it the most tested panel in the industry. From a flat ULT 1 sandwich panel to an ULT 5 panel which incorporates a stepped tray to the inner and outer leaves, the ULTIMA range provides the flexibility designers require to meet specific project requirements.

Testing & Certification

ULTIMA aluminium insulated spandrel panels have been rigorously tested for both fire and structural performance. With the widest field of application on the market, ULTIMA panels have been tested to BS EN13501-1 and can be constructed to achieve either an A1 or A2-s1,d0 reaction to fire classification. With multiple material and finish combinations tested and covered with our certification, the ULTIMA panel provides designers with the widest scope within the market.

The ULTIMA A2 range of spandrel panels are vacuum bonded within a temperature and humidity-controlled factory. This ensures the thickness of adhesive is controlled to within the limits allowable under the BS EN 13501-1 classification.

Each layer of the composite product has been tested to BS EN ISO 1716 in order to ascertain its GHC value. Panels are tested as a full unit to BS EN 13823 to determine their rate of heat release and production of smoke and flaming droplets.

Additionally, impact testing and wind resistance testing to CWCT standards (TN75/76) demonstrates the structural performance of the ULTIMA vacuum bonded panel and documents this within comprehensive technical reports.
