Aluminium Soffit Primary Duo Systems

Our primary duo soffit system is a simple twice bent soffit that is manufactured on an individual project by project basis. Primary duo soffit systems have many uses such as soffit covers; to clad existing soffit boards, verge, gable and bargeboard soffits; or as flashing, trim or cladding to the building roof eaves. Our primary duo soffit can be used either with an external or concealed gutter, or just as a soffit cladding.

Soffit Profiles

Aluminium Soffit Primary Duo is a highly adaptable product and as it is project specific we can manufacture virtually any profile, shape and size for the roof line.


Aluminium Primary Duo Soffit Fittings can be manufactured as standard and non-standard angles, stop ends, raking angles, apex angles, stepped angles, doglegs, junctions to bargeboards and verges.

Radius or Curved

If the project requires a curved aluminium soffit board, radius soffit cover or radii soffit cladding, to either a true or facetted curve, our primary duo soffit system is a great solution where horizontal, vertical, and most complex curves are achievable.

Gutters, Aluminium Eaves and Coping

This Aluminium Fascia Primary Duo integrates perfectly with Guttercrest's external gutters or concealed internal guttering, rainwater downpipes, and our range of aluminium eaves products, coping and cappings.

Optional Extras

Venting can be incorporated in to the aluminium soffits.

V-Ribbing to soffit gives a feature plank look like timber tongue and groove planking or weatherboard cladding. It also strengthens the aluminium soffit panels.

Special fabrications and architectural detailing.

Carcassing, Support Brackets and Framing System

Aluminium duo soffits can be fixed to many types of background, varying from timber carcassing to metal aluminium or galvanized steel carcassing and sub-framing. The correct carcassing design will shorten the installation time.

Bespoke, purpose-made brackets can be designed and manufactured to support the aluminium soffit cladding along with any integrated fascias and gutters.

Coatings and Finishes

Our aluminium fascia system is available Polyester Powder Coated in an array of RAL colours, BS colours, Heritage textured finish, metallic and anodised coating.

We can also source special colours and finishes to match your project requirements or we can supply our aluminium gutters in the standard mill finish.
