Product Details and Specification

These details are based on the current Online Metal Store Ltd product page, which lists the product title, 3 metre length, 2mm aluminium material, price, size options, RAL colour field, and custom-fabricated item notice.

Where This Product Is Commonly Used

This 2mm aluminium soffit Type 1 is commonly used on house extensions, new builds, roofline refurbishments, commercial buildings, office units, garden rooms, outbuildings, schools, and modern exterior upgrades. It is suitable where the underside of the roof edge needs a clean aluminium finish that works with the fascia, guttering, and wider roofline design.

For wider roofline planning, buyers can browse the full Fascia & Soffits range. The product page explains that aluminium soffit is installed under the eaves or overhanging section of a roof and can support ventilation, insulation, and external appearance when properly specified.

Why Aluminium Is a Good Choice

Aluminium is a practical material for soffit boards because it is lightweight, corrosion resistant, and suitable for external architectural use. It is easier to handle than many heavier materials while still giving a neat, modern roofline finish.

For soffits, aluminium can also reduce the maintenance normally associated with timber alternatives. The product page highlights aluminium soffit as lightweight, corrosion resistant, low maintenance, and recyclable. The Aluminum Association also describes aluminium as lightweight, strong, durable, and infinitely recyclable, with building material that can be recycled at the end of life.

Finish and RAL Colour Options

This product includes a RAL colour option, allowing the soffit to match or coordinate with the rest of the building exterior. This is useful when the same finish is required across fascia boards, aluminium copings, rainwater goods, cladding, trims, doors, windows, or other visible architectural metalwork.

The official RAL Colours page lists colour shades across RAL Classic, RAL Effect, and RAL Design System plus, which can help buyers check colour references before ordering. For architectural aluminium finishes, QUALICOAT UK & Ireland explains that QUALICOAT is focused on maintaining and promoting the quality of powder coating on aluminium and aluminium alloys for architectural applications.

Ventilation and Roofline Notes

Soffit design should be considered as part of the wider roofline, especially where roof ventilation is required. GOV.UK states that Approved Document F covers ventilation requirements within the building regulations for maintaining indoor air quality, with separate volumes for dwellings and buildings other than dwellings.

Before ordering, confirm whether your project needs ventilated soffits, non-ventilated soffits, continuous ventilation strips, over-fascia ventilation, or another roof ventilation detail. The correct approach depends on the roof construction, insulation arrangement, existing ventilation, and project requirements.

Installation and Ordering Notes

Before ordering, confirm the required soffit width, fascia depth, eaves detail, roof overhang, fixing surface, ventilation requirement, colour choice, and any joint or sealing requirements. The product page lists size options from 150mm to 800mm, so buyers should select the size that suits the project rather than relying on an approximate measurement.

This product is custom fabricated to the selected size and finish. The product page states that buyers should double-check measurements before ordering and that the item is non-returnable unless faulty.

For moisture and roofline detailing, GOV.UK’s Approved Document C page notes that the current edition includes information on resistance to moisture of floors, walls, and roofs, with examples of damp proofing and ventilation provisions. For roofing work, buyers should make sure installation is completed by a competent person and that soffit detailing is compatible with the building’s moisture control, ventilation, and roof edge requirements.

If the installation also needs matching accessories, consider Colour Coded Fastener Timber Pack of 25, Colour Coded Metal Fasteners - Pack of 25, and Colour Coded Sealant - 300ml.
