Soffit Type 3

2mm aluminium soffit for roof overhang and eaves detailing

Metal Profiles Ltd supplies Soffit Type 3 as a complete aluminium soffit system, with 3m lengths and matching accessories to help form a continuous roofline finish. The main soffit board is manufactured from 2mm aluminium and is available in standard widths from 150mm to 800mm. Each 3m soffit length includes one union, which helps connect sections and reduce the number of visible joints across longer runs.

This subcategory includes the main soffit lengths plus the parts needed to complete a run: 90° corners, internal joiners, colour coded fasteners, sealant, spray cans and touch up paint. The 90° corner and internal joiner are designed to support accurate connections within the soffit system and create a cleaner finished detail. The system is suitable for external soffit applications, eaves finishing, roofline upgrades and replacement work on existing properties and new-build projects.

Why aluminium is used for this soffit system

Aluminium is a sensible choice for soffit boards because it is corrosion-resistant, suitable for external use and 100% recyclable. It can also be polyester powder coated with external-grade paint, which helps the system suit UK weather conditions and external building details that are exposed to regular rain, wind and temperature changes. A wide choice of RAL and BS colours is available for matching the soffit to related roofline parts such as fascias and guttering.

If you are comparing roofline materials, our aluminium fascia and soffit benefits guide and benefits of using aluminium fascia and soffit article give a useful overview before you order. For a better understanding of the full roofline build-up, the what is a soffit UK guide is also worth reading.

What to check before ordering

Before ordering, confirm the soffit width needed, the number of corners and joiners required, and whether the run will finish cleanly at the end or needs a matching connection into another detail. It is also worth checking the fixing substrate and the overall run length so the correct number of sections and accessories can be allowed for. Standard sizes will suit many soffit replacement and roofline projects, but bespoke soffit solutions may be needed where the opening size or building detail does not fit the standard range.

If the soffit is being specified alongside a fascia system, our soffit or fascia page may help clarify where each component sits in the roofline. For projects that also involve rainwater goods, you may also want to review aluminium guttering Chelmsford Essex so the soffit, fascia and gutter detail can be considered together.

Product selection help

Choose the 3m length if you want to reduce the number of joints on longer runs. Select the correct width from the 150mm to 800mm range, then add the relevant 90° corner, internal joiner and fixing accessories to suit the layout. Use the colour coded fasteners that match the fixing method, and choose sealant, spray can or touch up paint where a more consistent colour finish is needed. If the standard widths do not suit the project, request an estimate with your measurements and corner details so the soffit can be assessed properly.
