The Harmer SML above and below ground rainwaters and waste systems are now listed on the website at www.rainclear.co.uk so you can browse and buy online at your convenience. Or put together a shopping cart and ‘save as a quote’ that you can email to a colleague to discuss before making a purchase.
Cast Iron rainwater and waste pipes are a bit of a specialist product, but we know there are specifiers and specialist multistorey, modern residential and commercial property contractors out there who would benefit from being able to put together a list of products and prices and get a printout. And when they’re ready, to be able to put it all in their cart themselves and pay for it (securely via Credit card or PayPal) without having to speak to anyone or wait for input from anyone else. That is the option Rainclear have offered by adding the Harmer SML ranges – above ground and below ground – to the website. So, now you can choose how you want to purchase your products for your project with as little or as much assistance as you require.
Why buy a Cast Iron Above and Below Ground Soil and Waste System?
- Cast iron has a proven track record for its longevity over the lifetime of a building.
- Quiet – Excellent acoustic performance – Typically, no special sound insulation measures required (The discharge of soil, waste and rainwater through a pipe generates structure-borne and airborne sound between habitable spaces and usually occurs because the pipe is filled with a mixture of air and water. The resultant noise will then be transmitted to lightweight ceilings, cupboards and similar constructions. Cast iron pipe systems however, because of the high mass per unit area of their pipe walls as well as the joint design characteristics, provide considerable noise reduction benefits when discharging soil, waste and rainwater within buildings.)
- High resistance to positive and negative pressure – no need to change material in sensitive areas. No expansion joints, deflection bends or other special expansion control techniques are required for the dimensionally stable pipes due to the low coefficient of thermal expansion of cast iron.
- Non-combustible, therefore does not require costly fire protection collars.
- Long life cycle (40 Years) and 100% recyclable – can be returned to the furnace to make new cast iron products.
