STEEL

Galvanised Steel Case Study PicSteel is the most affordable and initially cost effective of the metal rainwater ranges and it makes for a smart, stylish and contemporary rainwater system.

Strength & Durability
  • Steel is stronger than PVCu and when installed creates a more robust system.
  • Rainclear’s galvanized steel guttering will resist thermal expansion and contraction providing greater joint integrity – ideal in the UK where the weather variations really test the gutter joints.
  • Rainclear’s steel range is 20% deeper than other steel systems available and much deeper than most PVCu gutters offering greater holding capacity and better flow / discharge rates.
  • The product carries a manufacturer’s guarantee of 15 years although life expectancy should be 20 to 25 years.

Maintenance

Regular maintenance of all metal guttering is highly recommended but need not be arduous:

  • Clear out hoppers, outlets, angles and gutter lengths regularly to keep these free from debris.
  • Regularly inspect for any signs of deterioration. Ensure joints and fixing points are sealed and not leaking and that brackets are secure.
  • Always place ladders against structures and NOT the rainwater system.
  • Clean external visible surfaces regularly to maintain aesthetic appearance.
Installation
  • Rainclear’s steel system is dry-jointed with rubber lined union connectors so there is no need for silicone.
  • Steel is lightweight and easy to handle, 3m long lengths help quick installation.
  • It can be installed by a professional or an experienced DIYer.
  • Rainclear’s range of bracketry has been developed specifically for the UK market.

MODERN EXTRUDED ALUMINIUM

SnapIT Modern Extruded Aluminium Case Study Image

Strength & Durability
  • Extruded and pressed aluminium provides high durability, the material thickness is generally 2-3mm so it is much thicker than an equivalent steel system at 0.60mm.
  • The material lends itself to fabrication which offers flexibility to meet awkward site detailing.
  • Pressed systems are generally available in large profiles so is a great choice for light commercial and industrial buildings.
  • In a normal domestic application, a good quality aluminium system should last in excess of 25 years
Maintenance

Regular maintenance of all metal guttering is highly recommended. See ‘Maintenance’ above.

Installation
  • There are a number of jointing systems available depending on the systems and profile type.
  • Modern aluminium systems are lightweight, easy to handle and 3m long lengths make it an ideal choice for quick installation.
  • Rainclear’s SnapIT range literally ‘snaps’ together with no nuts or bolts – a popular choice for the self-build market.

TRADITIONAL CAST ALUMINIUM

Heritage Cast Aluminium Farm House Case Study ImageTraditional cast aluminium is at the top end of the price range, more expensive than extruded aluminium and steel but generally less than pre-painted cast iron. It is strong and long lasting (25-40yrs) and best suited to quality, traditional projects.

Maintenance

Regular maintenance of all metal guttering is highly recommended. See ‘Maintenance’ above
Strength & Durability

  • Cast aluminium is extremely durable and a great choice for coping with wet weather or snow.
  • Aluminium does not rust; any exposed aluminium surfaces simply oxidize to create a natural barrier.
  • Rainclear’s textured black finish emulates the look and feel of cast iron but is substantially lighter weight which makes it much easier to handle and install.
  • In a normal domestic application, a cast aluminium system should last in excess of 25 years.
Installation
  • Installation is straight forward with a traditional silicone and bolted joint, typically installed on fascia brackets, rafter brackets or rise & fall brackets.
  • The traditional cast aluminium gutters come in 1.83m (6ft) lengths with pipe choices of 2m or 3m long making it an ideal alternative to cast iron.
  • It can be installed by a professional or an experienced DIYer.
Style & Finish

Half Round profile

Victorian profile

Moulded profile

  • There’s a great variety of styles, half round is the most popular with Victorian ogee and moulded profiles also available.
  • Cast aluminium is available pre-coated in 26 standard factory-applied, powder coated options for immediate installation.
Eco-friendly & sustainable?
  • The life time value of aluminium is it very high, lasting 25 years or more.
  • 80% of the aluminium rainwater systems already in use in the UK have been manufactured from recycled aluminium and all aluminium is infinitely recyclable at the end of its life.
Guide Price

Prices obviously vary hugely and discounts are available on volume but based on standard 125mm, half round, powder coated cast aluminium gutter our guide price is £56.31 for 1.83m half round gutter length (including our current £20% Online Discount 06/18).

Who does it suit?

An aluminium system is ideal for those looking for something robust and long lasting. It’s available in both textured heritage finishes and more modern smooth finishes so looks great on a wide range of projects. Cast aluminium is generally a more cost-effective alternative to cast iron where a traditional 1.83m length spigot / socket style is required.

CAST IRON

Cast Iron Case study imageCast iron is the most expensive of the metal ranges, but with good reason, it offers an unrivalled life span compared to the other materials.

Strength & Durability

Cast iron is immensely strong and long lasting. It also looks superb on traditional style properties. It represents the most expensive material for guttering but this quality system should last at least 50 years with the correct maintenance, with many systems lasting 100 years plus!
Installation

  • As this is a heavier system it really needs to be installed by two people and from scaffolding. A professional or a very competent DIYer with assistance would be able to install this system.
  • Rainclear’s range of bracketry caters for all the traditional and most commonly used installation practices which make it an ideal choice for historical renovation projects.
Style & Finish

 

Half Round profile

Beaded Half Round profile

Victorian profile

Moulded profile

  • The cast iron range comes in Half-Round, Beaded Half-Round, Victorian Ogee or Moulded Ogee gutter profiles with round and square downpipe profiles to suit.
  • Cast iron is available in a ‘transit only’ primer coat for painting on site or a pre-painted black 4 coat finish for immediate installation.
  • Rainclear’s pre-painted black system is a full, wet applied, 4 coat factory finish. Read our ‘Primed or Painted: Which to Choose?’ blog [bit.ly/CIPrimedOrPainted] to find out why we would highly recommend spending that bit extra for the factory pre-painted cast iron because of how effectively the long-term benefits outweigh the initial incremental investment
Eco-friendly & sustainable?
  • Cast iron lasts a very long time and therefore a great choice for the environment as it uses less natural resources over the life time of its installation.
  • It oxidises very slowly over time giving off iron ashes which are carbon based and good for the environment. These promote green growth on plants and increase planktonic life in the oceans, thus helping to combat global warming. Recent studies have shown that adding iron dust to the oceans could have a dramatic positive effect on their health, increasing the oxygen output of our seas and oceans and reducing greenhouse gasses.
  • Cast Iron is also 100% recyclable.
Guide Price

Based on the 4” half round profile, primed for painting onsite:  £25.12 per 6ft length -  or pre-painted black, ready to install: £32.59 per 6ft length (including our current £45% Online Discount 06/18)

Who does it suit?

Cast iron is best on traditional heritage style projects and a must for listed properties.

Maintenance

Regular maintenance of all metal guttering is highly recommended. See ‘Maintenance’ above.

Plus – with Cast Iron, additionally

  • The factory applied, pre-painted cast iron should not require for 10 years, but the quality of onsite painting varies so be prepared to inspection regularly for signs of deterioration and repair/repaint any areas of corrosion damage in accordance with the manufacturer’s instructions

COPPER

Strength & Durability

Copper protects itself by forming a patina that ensures an exceptionally long product life span of 100+ years.

Installation

No special skills are required to install the copper guttering. The clever design makes installation simple. No soldering, riveting or messy silicone.

Style & Finish

Left to age naturally copper guttering will start to mellow within weeks, changing through various shades of brown and bronze until eventually forming a green / blue patina unique to copper. The time taken for the patina process to start depends on the location of your property, local weather conditions, distance from the sea and other forms of acidic pollution. It may be a more expensive choice initially, but its beauty, durability and recycle-ability – reducing environmental impact – makes it the more cost-effective choice as the long-term advantages far outweigh the initial outlay.

Eco-friendly & sustainable?

Copper is sustainable, it is 100% recyclable with most mined copper still in use today, reducing its environmental impact. Copper guttering is particularly suited for use in conjunction with a copper roof as a means of rainwater harvesting. It acts as an algaecide and fungicide, keeping growths such as moss and lichen to a minimum, therefore keeping gutters clear. Also, it mildly disinfects the water, which is great for putting on plants as it has a balanced pH and is free from chemicals such as chlorine. You get more suds when washing the car and it makes car and window washing smear-free (the streaks and dots are limescale).

Guide Price

Based on standard 115mm, half round profile, our current guide price is £56.38 per 3m length
(including our current £40% Online Discount 06/18)

Who does it suit?

Copper has been used on both contemporary and traditional style buildings. Its distinct appearance; bright, shiny, warm orange gradually dulling to dark brown over 7 years and then turning to Verdigris over 20 years, adds a specific architectural and a real ‘eco’ statement to most types of building.

Maintenance

It is a wonderfully low-maintenance option for guttering systems as it will not require painting or cleaning (if you are happy to allow it to patina with age) other than the removal of debris that may fall into the guttering

  • Always place ladders against structures and NOT the rainwater system
  • Check annually to ensure fixing points on brackets remain secure and joints are still sealed
  • Do not clean external surfaces abrasively to retain initial shine. The natural patina (a slow oxidisation of the outer molecular surface) creates its own protection against UV rays, heat, wind & water and should not be avoided.

QUARTZ ZINC

Zinc Case study imageStrength & Durability

Over time, Zinc forms a thin layer called a ‘patina’. This patina covers the material and protects it from weather elements, such as sun, wind and water but the change is practically invisible. It is immune to the harmful effects of UV rays. a lifespan of nearly 100 years

Installation

Lightweight and easy to install. No special skills required. The clever design makes it simple. We have produced some brief videos explaining things like gluing in the stopends. You can find it and others on Rainclearsys - You Tube:  http://bit.ly/RCUTube

 Style & Finish

Choosing Zinc as a rainwater solution is stylish statement for those after a different, unique finish that will maintain a striking appearance. The ‘quartz’ zinc we have chosen to stock has the colour and texture of ‘pre-weathered’ zinc.

Eco-friendly & sustainable?

There is no shortage of zinc as a resource and in addition it can be 100% recycled at end of life.    Many customers today want to lower their carbon footprint and reduce their impact on the planet. Zinc offers this

Guide Price

Based on standard 115mm, half round profile, our current guide price is £61.46 per 3m length
(including our current £40% Online Discount 25/06/18)

Who does it suit?

Quartz Zinc has been used on both contemporary and traditional style buildings. Its distinct appearance; a dark and textured gun-metal grey, adds a specific architectural and eco statement to most types of building. It is ideal if you live in an exposed location or by the coast. Its hard-wearing properties mean Zinc will last up to 50 years even in this most testing environment.

Maintenance

Requiring no decoration or cleaning, just the removal of debris that may fall into the guttering, makes it suitable for commercial, civic and residential buildings.

  • Always place ladders against structures and not the rainwater system
  • Check annually to ensure fixing points on brackets remain secure and joints are still sealed
  • Do not clean external surfaces abrasively. The Quartz zinc is pre-weathered and the natural texture of its patina (a slow oxidisation of the outer surface at the molecular level) creates its own protection against UV rays, heat, wind & water.
