Flash Harry Thermoflex is a pre-formed APP modified bitumen waterproofing membrane designed for torch-on waterproofing applications. Engineered for superior durability and long-lasting protection, this heavy-duty membrane is ideal for demanding waterproofing environments where strong adhesion and weather resistance are essential.
 
Thermoflex is commonly used on concrete roof decks, balconies, retaining walls, basements, planters, and water-retaining structures. Its reinforced torch-on system creates a tough waterproof barrier capable of handling harsh South African conditions and long-term exposure.
