Floplast 115mm Hi-Cap

About FloPlast 115mm Hi-Cap Guttering

FloPlast 115mm Hi-Cap (often referred to as Deepflow) guttering is the ultimate solution for properties that need to manage high volumes of rainwater. Featuring a deeper, wider profile than standard half-round systems, Hi-Cap guttering is specifically engineered for large detached houses, steep-pitched roofs, bungalows, and commercial or agricultural buildings. Because it holds a significantly larger volume of water, it helps prevent overflow during heavy storms and torrential downpours. At Gutters.co.uk, we supply the complete FloPlast Hi-Cap range, ready for fast and reliable UK delivery.

Why Choose FloPlast 115mm Hi-Cap?

Maximum Flow Capacity: The deep, semi-elliptical profile moves a massive amount of water quickly, making it ideal for areas prone to severe weather or flash flooding. Fewer Downpipes Required: Because the gutters hold and channel more water efficiently, you can often safely reduce the number of downpipes needed on your property, creating a cleaner exterior look. Heavy-Duty Performance: Manufactured from premium, lightweight uPVC, this system is tough enough to handle heavy snow loads and fast-flowing water without rusting, rotting, or bowing. Easy Push-Fit Installation: Despite its larger size, it uses the same user-friendly, pre-lubricated push-fit system as standard FloPlast guttering, saving time on site. Versatile Colour Range: Available in Black, White, Brown, and Anthracite Grey, allowing it to seamlessly blend with your existing fascia and soffit boards.

FloPlast 115mm Hi-Cap FAQ

What downpipes are compatible with the Hi-Cap system? The FloPlast Hi-Cap system is highly versatile. It connects perfectly with standard 68mm round downpipes for residential use, or you can pair it with larger 80mm round downpipes for commercial buildings that require maximum drainage.

Do I need Hi-Cap guttering for a standard 3-bed house? For most standard UK homes, 112mm half-round or 114mm square line is sufficient. However, if your home has an unusually large roof surface area, a very steep pitch, or if you regularly experience overflowing gutters during heavy rain, upgrading to Hi-Cap is a smart, preventative choice.

How far apart should Hi-Cap fascia brackets be spaced? Because this guttering holds a heavier volume of water, correct support is crucial. Fascia brackets must be spaced no more than 1 metre apart. In areas exposed to high winds or heavy snowfall, spacing should be reduced to 0.5 metres.

Can I connect FloPlast Hi-Cap to other brands? Yes, FloPlast's 115mm Hi-Cap system is designed to be highly compatible. It can connect directly to many other leading UK deepflow systems, and we also stock a variety of adaptors if you are linking it to an existing half-round or square profile.
