We're all affected by the steady advance of time. Years of exposure affects how everything looks. Marley Plumbing & Drainage have advanced the manufacturing process to create Life4. Life4 rainwater systems can withstand exposure for up to four times longer than standard PVCU rainwater gutters and downpipes. Looks better... Life4 gutters and downpipes have high gloss levels that are consistent with the fittings, improving the overall aesthetic of the system. The gloss level is typically 85% compared to a norm of 40 - 50% on standard systems. ...for longer Not only do Life4 products look better,...

■ inwater Life4 Life4 - the performance standard The benchmark for weathering tests for rainwater systems is set out within European standards*. The weathering test essentially mimics actual conditions, but also accelerates them in order that long term performance may be assessed. This artificial ageing type test consists of 1600 hours of exposure to high intensity UV lighting with specified levels of irradiation and condensation, which is designed to emulate approximately 3 years of natural weathering. Standard Marley rainwater systems achieve excellent results when measured to this requirement....

Marley rainwater systems offer complte roof drainage solutions for a variety of building sizes and styles. Pictured is a selection of key components within the range. For a complete list of products available in each of the rainwater systems, see pages 20 - 27. The iconic Marley socket The origins of the iconic double 'bump' on our rainwater pipe socket stem from the fact that Marley was the first company in the UK to manufacture rainwater gutter. The design emulated the traditional material most often used for drain pipes, cast iron. EASYCip Deepflow, Clip-master, Flowline and Deepflowl 50 rainwater...

age design Design basis To assess the suitability of a gutter system to drain the roof of a building the following factors need to be taken into consideration: 1. The effective roof area to be drained. 2. Rainfall intensity. 3. The flow characteristics of the gutter system. 4. The number and position of downpipes. Effective roof area The effective roof area can be determined by calculation in accordance with the following: 1. BS EN 12056-3:2000, Roof drainage layout and calculations. 2. The Building Regulations 2002 Approved Document H, Part H3. The formula and example shown below reflects the...

■ inwater Roofdrainagedesign Gutter slection Although aesthetic appearance is an important aspect in the slection of a particular gutter system, the following factors also need to be taken into consideration as they could influence the final choice of system. 1. The size of gutter and its flow capacity. 2. Whether the gutter is fitted level or to a fall. 3. If end or centre outlet position for downpipes are adopted. 4. The length of gutter to an outlet/downpipe. Flow capacity The maximum flow capacity of different Marley gutter systems can be compared from the tables shown opposite. The capacity...

General ■ Gutters should be fitted as high as possible to the roof edge. ■ It is recommended gutters are sized to be fitted level. ■ For 112-120mm nominal width gutters, the tile overhang from the fascia board should not be more than 50mm. For wider gutters, the overhang should not exceed the centre line. ■ Where over fascia ventilation is used, it may be necessary to use a gutter spacer and height adjuster bracket in conjunction with fascia brackets to ensure the gutter is fitted in the optimum position. ■ Fix fascia brackets with aid of a string line ■ A choice of top hung internal, RCK52,...

■ inwater Installationdata Rafter arm brackets can be used with all Marley gutter Systems. Additional structural fixings should be provided when used with a clip-jointed gutter system, to enable key fittings to be anchored and supported for the control of thermal movement. It is recommended that notched gutters are used on buildings without fascia boards as key fittings such as unions and outlets do not need to be secured and can be positioned adjacent to structural fixing points. Top rafter brackets, RTA1 or RTA1A, will need to be fitted before the roof is tiled. Side rafter brackets, RSA1 or...
