We recommend, as with any other painted surface, that periodic cleaning is carried out. Polyester powder coated aluminium requires only a soapy water solution to bring back the original appearance. Once a year, or twice in a marine environment, we recommend that the gutter system is cleaned and joint integrity is checked. Any collected gutter debris should also be removed.
Is aluminium guttering expensive?
Typically aluminium guttering is more expensive than a uPVC equivalent but is quite comparable in price to a high end uPVC system. As our aluminium gutters have a 50 year functional life expectancy they will last much longer than a uPVC system saving money in the long term. Aluminium systems are also offered in a larger variety of colours and styles giving the homeowner more choice.
Does aluminium guttering need painting?
Our aluminium gutters are supplied pre-coated with a durable polyester powder paint colour of your choice. With minimal maintenance, our architectural grade paints can provide a decorative finish for in excess of 25 years.
Can metal gutters be painted?
Following many years of service, once the paint finish loses its original lustre, the painted surfaces can be overpainted using a good quality metal paint, providing a durable decorative finish for many years to come.
How long will aluminium guttering last?
Alugutter products are manufactured from marine grade aluminium and coated with exterior grade polyester powder paints. The aluminium will never rust, rot or crack like cast iron or steel equivalents and polyester powder paint is one of the most durable decorative finishes available. Our products have a functional life expectancy of approximately 50 years, and with minimal maintenance, the colour coatings can provide a decorative finish for in excess of 25 years.
What is the fire rating of your products and do they comply with Approved Document B (fire safety)?
Aluminium does not burn and is classed under BS476-4 as a non combustible building material and Class A1 under European regulations.
Our decorative polyester powder coatings used on our products are rated as follows:
BS476-6 = Class 0 (Fire propagation)
BS476-7 = Class 1 (Surface spread of flame)
EN13501-1 = A2 - s1,d0.
This means our products conform fully with Approved Document B requirements and can be utilised on any part of any building without limitation.
Do aluminium products require specialist installers?
Our products are supplied with installation guides and can be installed by any competent trades person or even DIY enthusiast.
What is the best method of cutting aluminium gutter and pipes lengths?
Use either a hack saw with 18 teeth to 1” blade, or circular saw with appropriate aluminium cutting blade. Do not use angle grinders, as this will create an unsightly burr to the cut edges.
How can I protect my gutter system from damage caused by sliding snow?
Modern buildings now have heavily insulated roofs to prevent heat loss which means snow buildup on roofs is becoming more common. The BS EN12056-3 rainwater drainage design standard advises that gutters should be installed so that the front lip aligns with the pitch of the roof. This prevents sliding snow impact and the gutters becoming damaged.
What type of screws/fixings should be used with aluminium products?
The use of incompatible screws and fixings will cause electrolytic corrosion between the two metals. Only austenitic stainless steel fixings as supplied by Alugutter should be used.
How do I know what size of guttering is suitable?
BS EN12056, the current design standard for sizing rainwater goods. The standard states that a 1 year storm event is to be used for all external gutters and lists the various local rainfall intensities applicable. Here is an in depth guide. We also offer a free drainage design service and can recommend suitable products. Please email your roof plan and elevation drawings by clicking this link
Should I use a traditional or contemporary gutter system?
The style of eaves gutter system is usually dictated by the style of the building, however it is the specifiers decision. Traditional styles are available conforming to BS 8530 and we also offer contemporary styles with a modern Snapfit jointing method.
What should I use to seal guttering and pipe joints?
All gutter and pipe joints should be sealed with Alugutter Code SU1 low modulus high performance silicone sealant. Joint surfaces must be cleaned with a PVC solvent cleaner and dry prior to applying the sealant.
Should external rainwater pipe joints be sealed?
We recommend that all pipe joints are sealed with low modulus silicone sealant. Sealing the joints prevents water over spilling at tight bends where water turbulence could build up, locks the pipes in position preventing rattles and improves flow performance as air is not being sucked in through open joints.
Should I install the gutters level or with a fall?
Small domestic gutters are generally installed to falls of 1:600 to enhance the flow towards an outlet. However, our systems are all high performance in terms of flow capability and can also be installed level if preferred.
Will aluminium gutters expand and contract like uPVC?
All metal gutters expand and contract but the amount of thermal movement will depend on the metal used. Aluminium expands approximately 1mm per 1m, but does not expand as much as uPVC systems. All of our systems are designed with a 3-4mm expansion gap at each joint to allow for thermal movement without breaking the silicone joint seal.
