Why choose aluminium cappings and secret fix cappings?

Aluminium is a strong choice for cappings because it forms cleanly and holds straight lines over long runs. It is also lighter than many alternatives, which supports easier handling on site while still providing the strength needed at exposed roof and wall edges.

A secret fix system is often specified where a cleaner look is required. Fixings are concealed, helping create a smooth, continuous line along the parapet and reducing visible fastening points.

With the right coating system, aluminium performs well in Irish conditions, including exposed and coastal locations. Powder coating also supports colour matching, so cappings sit comfortably with surrounding roofline and façade details.

Benefits of Aluminium Cappings and Secret Fix Cappings

Made to Suit Your Parapet & Perimeter Details

Cappings are produced to your dimensions and wall build-up, supporting accurate fits at corners, returns, and junctions.

Cleaner Finish At Exposed Edges

Straight lines and crisp folds help create a tidy roof perimeter, particularly where the capping is visible from ground level.

Improved Weather Protection At Junctions

Well formed cappings help protect parapet tops and vulnerable edges from ongoing exposure, supporting a drier, better finished junction.

Built For Long Term External Use

With an appropriate coating specification, aluminium remains a dependable option outdoors and generally only needs routine cleaning to keep its appearance.

Secret Fix Options For A Smooth Appearance

Concealed fixing systems reduce visible fasteners and help maintain a cleaner line along the parapet.

Colour & Finish Choice To Match The Scheme

Powder coating supports colour matching with surrounding trims, cladding, and roofline elements, with a choice of standard and textured finishes.
