Superior Insulating Value across the entire wall and roof area is assured with LS-36 panels. The advanced polyurethane core provides enhanced insulation values that significantly lowers heating and cooling costs.
 
One-Piece Construction process assures rapid completion of the wall and roof system. Factory fabricated composite panels are attached directly to the supporting structure and multiple steps to construct the insulated wall and roof are eliminated. Faster building completion means reduced construction and interim financing costs.
 
Lightweight yet Structurally Strong panels weigh only 2 ½ to 3 ½ pounds per square foot, but are structurally strong enough for long spans that can significantly reduce costs for frame support.
 
Impermeable Faces & Built-in Thermal Breaks ensure the highest insulating values are maintained for the life of the building. Panels are manufactured with impermeable faces and when installed the insulation is completely encapsulated by metal trim that creates an impermeable membrane on all sides of the panel. The aged “R” values are comparable to the initial “R” values many years after the buildings original completion. Assured thermal values mean lower heating and cooling costs.
 
Class 1 Polyurethane Foam meets the requirements of the major model building codes for many types of construction. Unlike panels with expanded polystyrene cores they will not produce a self-propagating fire. Local building codes may require automatic fire suppression systems for most installations.
 
Concealed Attachment with clips and fasteners at the side joint of the panel offers a clean high profile appearance. No more barn like metal building looks.
 
Insulated metal panels are lightweight, yet very strong and durable attributing to reduced costs for erection and structural support.
