Description
A square downpipe is the vertical component of a rainwater system that carries water from the roof gutters down to the drainage gully or soakaway. Unlike traditional round pipes, the square line system is often preferred by architects and homeowners for its “flush” fit against external walls and its ability to handle significant water surges without overflowing.
Why Choose Square Line over Round Drainage?
While both systems are effective, the 65mm square downpipe offers a larger cross-sectional area, meaning it can technically move more water in a shorter amount of time. This makes it an ideal choice for larger roof areas or regions prone to flash flooding. From a design perspective, the sharp angles of square guttering provide a tailored, modern finish that complements anthracite grey or black window frames and contemporary brickwork.
Built for the 2026 UK Climate
At ECO HEAT SHOP LTD, we ensure our drainage products are manufactured to withstand the toughest environmental conditions. Our downpipes are made from unplasticized PVC (uPVC) that is UV-treated. This prevents the plastic from becoming brittle or “chalky” after years of sun exposure. Whether it’s freezing winter temperatures or summer heatwaves, these pipes maintain their structural integrity and high-gloss finish without warping.
