Roofing and Green Roof Design
ALT roofing and waterproofing membranes are seamless, cold applied, flexible reinforced, UV, chemical and root resistant PMMA membranes for flat or inclined decks.
Our roofing systems are the ideal solutions for most every substrate including modified bitumen, asphalt built up roof (BUR), concrete, wood, steel, zinc, lead, copper and plastics. Single coat application makes our membranes cost effective, especially for large projects. ALT roofing systems include various roof assemblies such as insulated roofs, inverted roof membranes (IRMA), recovery, flashing only, protected roof membrane, green roofs, built up roof (BUR), recovery and direct to deck.
Since the products are liquid applied, the result is a seamless waterproofing system in which even the most complex roof penetrations can be reliably and durably incorporated. It is also extremely weather-resistant, flexible at low temperatures and its surface can be finished in a wide range of RAL colors.
