PowerTape: The Essential Reinforcement Tape
for Stained Glass

PowerTape - Reinforcement Tape

PowerTape reinforcing tape is an invaluable tool for stained glass artisans, used to strengthen stained glass structures, improving their resistance to deformation and vibrations.

In the early 20th century, the development of reinforcing tape revolutionised the art of stained glasswork, providing a welcome alternative to the cumbersome lead came. The sturdy steel tape, coated with a thin layer of copper, quickly gained recognition for its simplicity and affordability, becoming an indispensable element in stained glass creation. Equally important was the fact that stained glass assembled using this technique featured a narrower connecting seam compared to those made with lead came, allowing for the creation of more detailed panels where the lead came did not obscure smaller pieces of glass.
