Can the Cascade cast iron style system be painted?

Yes, the Cascade system has been designed to replicate authentic cast iron detailing in modern plastic (uPVC) form while offering the benefits of durability, corrosion resistance, and low maintenance. However, if you wish to paint the external surface, you should take account of the manufacturer’s guidance: the Cascade components are fully UV‑stabilised and come in a range of heritage colours (Classic Black, Oxford Blue, Olive Green, Sandstone, Porcelain White, etc), so painting is rarely necessary. If painting is undertaken, ensure suitable preparation (cleaning, priming, and using exterior-grade paint compatible with uPVC) and verify that this does not invalidate any warranty or guarantee.

How do I make a swan neck/offset for the Cascade cast iron style range?

The Cascade range is built with a comprehensive system of fittings that allow for offsets, turns, swan-necks, adaptor pieces, and bespoke runs, making it suitable for both refurbishment and new build situations where geometry is non-standard.

For round downpipe options (e.g., 68mm round downpipe in the Roundstyle/Deepstyle systems), there are offset bends and adjustable offset pieces listed (for example, 250–650mm adjustable offset for 68mm downpipe in the Cascade range).

If you are working with large roof areas (Deepstyle or 170 mm high-capacity systems), there are matching downpipe and hopper options available that are designed for more complex routing.

Can Cascade cast iron style guttering be used on listed or conservation buildings?

Yes, the Cascade range was specifically designed for both new-build heritage-style buildings and the restoration/renovation of older structures, including those in listed and conservation areas. Because the system replicates cast iron detailing and is available in authentic heritage colours, it offers the aesthetic required for conservation projects while avoiding the weight, cost, and maintenance issues associated with genuine cast iron.

Is Cascade guttering compatible with existing rainwater systems?

Yes, the Cascade range is designed to be compatible with many existing rainwater systems, making it easier when refurbishing or upgrading sections of an existing drainage run rather than replacing it entirely. For example, the Cascade Roundstyle system is fully compatible with the Cast Iron Style Soil System and traditional cast iron.

How is Cascade guttering installed?

The installation of the Cascade range follows standard uPVC rainwater system practices, with additional attention to heritage-style detailing. The range features a push-fit system, making installation easy. All that is required is to simply click the necessary fittings into place.

How does the cost of Cascade compare to traditional cast iron guttering?

Cascade offers a cost-effective alternative to traditional cast iron guttering while delivering the same heritage appearance. The material cost of Cascade is generally lower because uPVC components are lighter and easier to manufacture than those made of heavy cast iron.

Installation is also simpler and faster, as the lighter components are easier to handle, requiring fewer personnel and reducing on-site labor costs. In addition, Cascade’s durable, UV-stabilised construction means that maintenance costs are significantly lower over time, as the system is resistant to corrosion, splitting, and discoloration, unlike cast iron, which can require regular painting and repairs.

Can Cascade guttering be used for modern architectural designs?

Absolutely. While the Cascade range is heritage in style, it is also suitable for modern architectural outcomes, particularly where a building blends contemporary design with traditional detailing.
