Gold Star Guttering - SuperDeep 170!

Castilion School SuperDeep 170 rainwaterA new build extension at Castilion Primary School in North Thamesmead was one of the first developments in the UK to benefit from Kayflow’s SuperDeep 170 rainwater system.    Nearly four years on the high-strength, high-capacity system is performing beyond expectation.

Castilion Primary School is one of a number of community primary schools in the London Borough of Bexley, with admissions from nursery to 11 years old.  Earning an Outstanding from Ofsted the school has a favourable reputation and is popular locally and further afield. 

Environment and facilities play an important role in pupil development.  The school Mission Statement is ‘Raising the standards and expectations of all pupils based on their needs, attributes and achievements in a secure, happy and stimulating environment.’ This is further supported by comments from Headteacher, Steve Pepperrell, “…we are a strong team of experienced and committed staff working in a modern building with excellent facilities.”  The school’s new two storey extension is representative of this commitment.

Mental Arithmetic

A project manager from the Major Projects team at the London Borough of Bexley explains the principles behind the specification of the Kayflow system.  “We had to ensure that the rainwater goods would handle all the rainwater from the pitched and flat roof areas which included any water directed from existing roofs into the new guttering and downpipes.  Our calculations enabled us to determine guttering depth and volume and the number of downpipes required.

“Through experience we ensure that a rainwater system can handle a little more than the volumes calculated for the total roof area.  For Castilion Primary School we required 170mm guttering and 110mm diameter downpipes.”

Super Powers

With a market leading flow rate of around 10 litres per second, the SuperDeep 170 has a huge drainage capacity and each fascia bracket is able to carry a weight of 125kg, that’s around 19.5 stone.  Recommended for fixing at 600mm intervals, once the brackets are in position the guttering simply clicks into place, it is an extremely easy product to install.  

The SuperDeep 170 system is available in black or grey.  This outer skin is co-extruded onto a white base which helps to deter heat build-up, a common enemy of large guttering systems; reducing expansion and contraction within the system and the risk of leaks.

The strength of the SuperDeep 170 system comes from its carefully designed structure and superior wall thickness. The fittings are designed with strength in mind and are positively fixed, including the 90˚ angle which has been produced in external and internal formats. This increases the strength of the system and provides additional support in the areas where it is needed most.

“We specified PVC rainwater goods because they are cost-effective and maintenance free.  Also, if we were to require replacement items at any point in the future they are readily available,” continued the project manager from the Major Projects team for the London Borough of Bexley.
