New guttering system from Swish can cope with any rainfall conditions

  • 6 Jun 2017

Swish has developed a portfolio of products designed to cope with the wide range of rainfall conditions experienced in different areas of the country.

The British weather is extremely variable. In some areas of the country – Wales, Scotland, The Pennines etc, we see a huge amount of rainfall – as much as 180 inches per year, making them some of the wettest locations in Europe. However, areas such as London, East Yorkshire and Norfolk, receive as little as 24 inches per year.

According to Swish Building Products, the market requires guttering systems with the appropriate capacity to do their job with optimal efficiency, whatever the prevailing conditions may be.

Swish has developed a SuperDeep170 for areas of high rainfall intensity. The SuperDeep170 is a PVC profile guttering system that has been designed to handle a much higher flow rate – around ten litres per second – than standard guttering.

The system has the capacity to carry ten times more water than a standard half round gutter and at least five times more water than a standard deep system.

SuperDeep170 is suitable for buildings with large roof areas with high run-off potential as they therefore need a much bigger capacity system.

According to Swish, SuperDeep170 can even reduce the number of downpipes needed with consequent reduction in the frequency and lengths of below ground connections etc.

A consequence of increased capacity is an increase in potential weight-loading and resulting pressure on the gutter fixing system. The high strength bracketing developed for SuperDeep170 is said to be capable of holding over 125kg on one unit and well able to handle the gutter system running at full capacity.

Thermal expansion and contraction can result in an increased risk of leaks but Swish has raised the benchmark for the industry by co-extruding the SuperDeep170 gutter profile onto a white base with a black of grey outer skin.

The white base material helps reduce heat build-up through reflection. The dark outer skin co-ordinates with other components in the range and provides the required aesthetic to satisfy the demands of architects and other construction professionals.

Where high capacity systems are not a requirement, Swish has a range of standard rainwater products, manufactured in round, square, deepflow and ogee profiles and in a range of colours.

Half-round and ogee profiles in cast iron effect in black with specially moulded components that closely reflect the traditional detailing of cast iron systems are also available.

With SuperDeep170 you can build anywhere in the UK and be confident that it has the right capacity, profile finish and colour.
