Introduction to Window Flashings
Window flashings are crucial in preventing water damage to walls and windows. When installed with a building wrap, flashings redirect rainwater and prevent moisture from leaking into internal wall cavities. Choosing the right flashing helps protect against costly repairs and ensures long-term waterproofing.
Built for Window Protection and Long-Term Performance
Without proper window protection, your structure becomes vulnerable to water ingress, especially around timber frames and cladding junctions. Our external window flashing diverts water away from walls and cavities, helping prevent future water damage.
