Parapet and Boundary Wall Guttering

Our Aluminium Parapet and Boundary Wall Gutters can also be manufactured as a parapet gutter liner. Metal parapet and boundary wall gutters will be manufactured to suit each project as we can produce an infinite amount of gutter sizes to suit your individual project requirements. Special profile parapet and boundary wall gutters can be fabricated or pressed.

Parapet and Boundary Wall Design

Having the correct parapet and boundary wall flow capacity is more critical than with an eaves gutter, so calculating the flow rates accurately is essential. These flow rates can be calculated by our designers so please contact our technical department if you would like assistance. An additional freeboard (of up to 75mm) over the maximum water level is recommended to allow for splashing and waves.

Consideration needs to be taken when deciding on the gutter gauge and support to whether the parapet and boundary wall gutter is going to take foot traffic. It is good practice to have some gutter overflows as the consequences of overflow or leakage are serious, so their correct design and installation are very important.

As the parapet and boundary wall gutters are part of the roof they may also be need to be insulated to comply with thermal requirements with respect to excess heat loss, thermal bridging and the risk of condensation.

Gutter Brackets and Fixing

These aluminium parapet and boundary wall gutters normally sit in or on support brackets, carcassing or a gutter board and should be fixed to these. Valley gutter brackets can be manufactured to suit.


We produce a comprehensive range of fittings to complement the parapet and boundary wall gutter system. These include stop ends, overflow stop ends, gutter overflows, running outlets, back outlets, side outlets, chute outlets, sleeve outlets, sump outlets, gutter angles, non-standard and irregular angles, raked angles, and apex angles.

Other special items can be designed and manufactured to your specification, please ask.
