Aluminium fascia profiles

Square &
Rectangular Fascias

Whilst relatively simple in design, square and rectangular profiles provide a very pleasing if more traditional appearance to the eaves.

 

Elliptical
fascias

Elliptical fascias provide a modern and sleek eaves profile whilst keeping the leading edge of the system to a minimum. Useful if you wish to minimise the appearance of a deep roof construction.

Bullnose &
quadrant fascias

Bullnoses and Quadrant fascia profiles offer a more contemporary appearance and are now a very popular selection.

 

Sigma
fascias

Dales Sigma Fineline is a recent addition to the fascia range. Fascias are individually pressed from sheet aluminium to create the appearance of a structural steel member.

Design & Specification Service

Project Management Design & Specification Service

On receipt of project drawings, we assign a Project Manager to each project. They provide a single point of contact throughout the life of the project, from initial design to completion. Relevant criteria, including support methods, material requirements and budget are established with the specifier. The Project Manager can prepare CAD drawings, calculations, NBS Specifications and quotations, providing a complete specification service. To discuss the requirements for your project, our Project Management Team can be contacted on Tel: 0115 930 1521.

Professional Indemnity Insurance

Dales Fabrications hold full Design/Professional Indemnity Insurance with a first-class security in the London market. This allows architects and specifiers to use our products with confidence.

Integrated, Bespoke Systems

The eaves for most buildings require a combination of rainwater, fascia and soffit components. Through consultation and liaison with individual specifiers on a project by project basis, Dales Fabrications design and manufacture engineered eaves systems. These utilise different standard fascia soffit and rainwater components that can be combined to form bespoke solutions for a broad variety of building types. Using standard components in a modular way reduces delivery times to the minimum possible.

Fascia Profiles

Dales design and manufacture fascia profiles to almost any shape, size or proportion including curved and elliptical designs. As part of our specification service detailed drawings will be prepared which can be inserted directly into your own drawings. Systems can be covered by our guarantee, which may be up to 25 years, dependant on location and exact finish specification, terms and conditions apply. Example drawings can be downloaded here. Whilst all profiles are designed specifically for individual projects, a number of typical profiles are indicated above.

Flexible Response

The total eaves concept works best through liaison at an early stage. Experienced Technical Managers at Dales can attend design coordination meetings to discuss your eaves system requirements and can be contacted using the chat facility or on Tel: 0115 930 1521. On submission of drawings or proposals, Dales will advise on the most efficient method of support and the practical options available. Extensive experience and technical understanding of different materials and their interaction with one another means that attractive and practicable systems can be designed.

Design Considerations

Gutter Configuration : Hidden or Exposed

Traditionally, gutters have been exposed and Dales offer a wide range of decorative and functional gutter profiles, which can be used to compliment an exposed gutter configuration.

Hidden gutter configurations provide a more contemporary appearance and allow more imaginative fascia profiles to be used, from plain fascias to trapezoidal, bullnose, raked and elliptical designs.

Fascia Profiles

Dales are able to design and manufacture fascia profiles to almost any shape, size or proportion including curved and elliptical designs. As part of our specification service preliminary drawings can be prepared which can be inserted directly into your own drawings. All systems are designed on an individual project basis and a 25 year guarantee may be available, subject to terms and conditions. Example drawings can be downloaded here.

Selection of Soffit System

Dales offer a wide variety of different soffit types, from secret fix panels to secret-fix planks, more details are available here.

Bespoke Manufacture & Factory Assembly

Dales manufacture everything on a bespoke basis so secret-fix and standard fascia or soffit panels can be adapted to provide hinged access panels for electrical or other access. Pre-cut holes for items such as waste or other vents can be incorporated into panels during manufacture to eliminate site cutting. This can be further enhanced to integrate LED lighting or other components using pre-site assembly in our factories. To discuss specific requirements please contact our Project Management Team on Tel: 0115 930 1521

Eaves System Support

Whilst Dales eaves systems can be supported directly from timber, SFS or a combination of trimmers and timber, Dales recommends that its systems are designed using its Monocoque Support System.

Colour, Finish and fire

Colours & Finishes: Ordering Samples

Details of the colours and finishes available can be found here.

Fire: Aluminium & Finishes

Anodised Aluminium
A1 Classification Reaction to Fire EN BS 13501-1:2018
Solid sheet or extruded mill-finish or anodised* aluminium products are: A1 non-combustible and are classified as making ‘no contribution to fire”: EU Commission Decision 04.10.96 See also https://publications.europa.eu/en/publication-detail/-/publication/999ef8f3-56e7-4a99-8e20-01f910b77d2e/language-en (*anodising is an inorganic finish)

Polyester Powder Coatings: A2 s1, d0 Classification Reaction to Fire EN BS 13501-1:2018
Dales recommend Syntha Pulvin (Sherwin Williams) architectural polyester powder coatings for aluminium products coated at its Syntha Pulvin Approved & ISO 9001:2015 Quality Assured coating facility in Ilkeston. All powder coated items are coated in accordance with the stringent standards demanded by Syntha Pulvin as part of their accreditation process which meets or exceeds the minimum requirements of BS 12206-1 2004. Dales also supply aluminium products in Syntha Pulvin (Sherwin Williams), Interpon D (Akzo Nobel) and Drylac (Tiger) architectural polyester powder coatings using only each manufacturer’s Third Party Approved Applicators.

Syntha Pulvin (Sherwin Williams), Interpon D (Akzo Nobel) & Drylac (Tiger) are independent and separate manufacturers of architectural polyester powder coatings for aluminium and each manufacturer unequivocally states that all their ppc products are: A2 s1, d0 very limited combustibility (EN 13501-1 Classification of reaction to fire). Each manufacturer can provide fire test evidence conducted by independent test laboratories, if required.

Fire: Aluminium Eaves Design

Dales can provide a RIBA Approved Material seminar on this subject: More information on the full title, content and how to book is available here.

With regard to all aspects of detailing for fire-prevention and prevention of spread of fire, as with all projects, specifiers, developers and their main contractors should employ and consult a suitably qualified and experienced fire safety engineer to ensure that all details submitted, specifically including those details which may involve Dales ppc or anodised aluminium products are considered appropriate, suitable and compliant with current building regulations & the overall fire strategy for the project.

Specifiers, Developers and Main contractors are further invited to consider the RIBA Fire resources web page at https://www.architecture.com/campaign/grenfell-tower

The design liability of Dales will be limited to the reasonable skill and care of a specialist sheet-metal fabricator.

Quotations provided by Dales include for the items expressly listed and do not include for the supply (or design) of any supplementary items such as, but not limited to; insulation, plywood, vapour barrier, fire protection, insect mesh or mastic/sealant (other than gutter sealant). Any reference to bill pages, specifications or drawings is listed for information only.

Guarantees:

Dales products, whether supplied in anodised or architectural polyester powder coated finish can usually be provided with guarantees, dependant on their geographical location and specific environment and subject to terms and conditions.

Marine specification

It is the specifier’s responsibility to ensure that Marine Specification is specified in their contract particulars, and our Project Managers can assist by advising on and providing appropriate NBS Specification clauses.

If architectural polyester powder coating is to be used in a coastal or marine situation then a marine environment paint specification should be considered where the development is in an aggressive environment, especially industrial and marine environments, ie. within 2km of the sea or tidal estuary.

In a non-marine environment, polyester powder coating is applied to give an average 60 microns paint film to visible faces only, however; to enable a Marine Specification guarantee to be considered, a minimum of 60 microns of paint must be applied to both internal and external surfaces and A2 stainless steel fixings used.

Any guarantee which the polyester paint manufacturer will offer is determined by them on an individual project basis upon completion of a questionnaire submitted by the customer and possible site visit by the paint manufacturer, both of which must be completed prior to any order being placed. It should be borne in mind that if the goods are on the seafront or within 1km there is a possibility that the paint manufacture may not be able to offer a guarantee.

Acutely Exposed or Industrial Environments

For acutely exposed marine or industrial environments Marine Specification can be further upgraded in several ways, which includes one or more of the following:
• changing the base aluminium alloy to a ship-building alloy,
• changing the powder coating to Qualicoat 2 specification,
• amending secondary supports to all aluminium,
• changing fixings to A4 stainless steel (provided such suitable fixings are available) or
• moving to an anodised finish.

If you consider that your project may be located in an acutely exposed marine or industrial environment, please contact one of our Directors or Project Managers to discuss this further. Please bear in mind it is not always possible to guarantee products installed in harsh environments.

Durability, Loadings & 3D Modelling

Durability

Dales systems are designed to give a low maintenance life of 60 years in rural and suburban conditions & up to 25 years in industrial conditions, dependant on the exact environment. For marine environments see above.

Operation & Maintenance Information

As part of the Dales Project Management: Design & Specification Service a full technical guide is issued to site that includes A3 copies of all Dales detail proposal drawings in full colour and generic system fixing instructions as a comprehensive Technical Guide. This also includes a comprehensive ‘Fixings Identification List’ that identifies where each fixing is supposed to use, the same information is noted on the detail proposal drawings too.

It is the customer’s responsibility to request a full O&M pack from Dales, which will include a complete detail drawings pack and the relevant generic fixing instructions complete with the maintenance schedule and any guarantee originally requested in the original customer order.

Loadings: General

Both gutter and fascia soffit systems are designed to accommodate loadings in excess of those induced when the gutters are operating at full capacity. Snow guards are recommended where sliding snow may cause impact loading in excess of normal design criteria (see BS EN 12056-3 2000). For wind and other specific loadings please contact our Project management team on Tel: 0115 930 1521.

Loadings: Finite Element Analysis FEA/FEM Modelling

As part of its overall design process Dales may be required to provide a computer-generated Finite Element Analysis (FEA) or similar report that may indicate whether a system designed by Dales is likely to withstand specific wind or other loadings. In the case of wind-loadings, it is the customer’s responsibility to ensure that they correctly inform Dales of the “local wind pressure design cladding load for the specific element of the works” as well as the height and location of the detail that Dales are to supply.

Please note that Dales reserve the right to pass on any costs incurred in producing any such report or calculations, as well as any additional product costs that the conclusions from the report deem necessary. Since it is not possible to fully predict all the dynamic factors that may arise, any report generated through a computer-model will always be limited to some extent in its ability to predict real-life outcomes with absolute accuracy.

It is therefore the customer’s design and financial responsibility to ensure that any such FEA/ FEM report that Dales may provide is deemed adequate, sufficient and compliant with the project design specification by the Project Structural Engineer in terms of the; model, loadings and physical properties of the materials used.

3D Modelling

Where Dales are required to design their systems, for whatever reason, using 3D modelling software, typically AutoDesk Revitt, lead times for the preparation of detail design drawings (Dales proposal drawings) or 3D models are likely to be increased. This may on occasion affect overall lead times for the provision of manufactured products and Dales are not liable for any costs however they may arise due to the increased design time that results from the need for 3D computer modelling. Dales reserve the right to charge for any such increased design time incurred in their design office that results from the need for 3D modelling.

Thermal movement

Dales design all systems to accommodate the extremes of temperature typical in the UK. For overseas projects, please contact Dales to discuss the requirements of your project.

Curves, Ventilation, Joint Design & Fixings

Curving Eaves Systems

The visual effect of a finished curved eaves of other system whilst technically demanding and costly always gives a finished project a ‘landmark’ quality. Dales have a long heritage of designing and manufacturing curved products since the business was first established in 1977. When specifying curved eaves systems, it is recommended that one of our Directors or experienced Project Managers meet with the project design team to discuss the possibilities, use the chat facility or call us on t.0115 930 1521

Curved eaves systems may be manufactured to a pure radius, whether the fascia is a bullnose or more usual rectangular section. In many instances, a curved front fascia with a facetted soffit can be a (relatively) cost effective and intelligent solution to the curved system requirement.

Ventilation

Many people are unaware that Frank Dales invented the ventilated metal fascia soffit, holding a patent for the design for many years. Ventilation equivalent to 10mm or 25mm gap, or even greater can be incorporated into the eaves or verge, whether as part of the fascia or soffit system.

Joint Design: Secret-Fix, Modulation to Grid or Curtain-walling

Whilst fixings at joint locations are positioned to be as unobtrusive as possible, a secret fix joint option is also available. Factory applied jointing strips serve to both stiffen panel and fascia profiles and provide a joint completely free of visible fixings.

Dales supply most systems in standard 3m lengths, however, whether secret-fix or otherwise joints can be modulated with fenestration or grid centres. If modulation is required, it should be identified in the NBS Specification clause and Dales Project Managers can assist and advise on any costing implications that may arise due to modulation.

Access Panels & Off-site Assembly

Both Secret-Fix and standard soffit panels can be adapted to provide large or small hinged access panels for electrical or other access. Access panels can also be provided for planked soffits. When required, pre-cut holes for items such as waste vents can be incorporated into soffit or fascia panels to eliminate site cutting. This can also be used with off-site assembly to integrate LED or other lighting and other components. To discuss specific requirements please contact our Project Management Team on Tel: 0115 930 1521.

Fixings

Fixings present a potential weak link in any system, as such Dales take the process of fixing selection as seriously as the design of the system itself. All fixings have been selected after careful consultation with manufacturers and rigorous testing for both ultimate strengths and potential incompatibility issues. All necessary fixings are supplied as part of the complete package from Dales.

Sustainability

BS EN ISO 9001: Design & Manufacture

Dales Fabrications have been working within the constraints of BS EN ISO 9001 accreditation since 1993. Our ISO 9001: Design & Manufacture certificate is available to view here.

Aluminium: The sustainable choice

Aluminium is recognised as one of the most sustainable materials for use in the building industry. This is due to the vast natural deposits of bauxite (aluminium ore) and product longevity, combined with low recycling costs. Around 98% of the aluminium used in UK construction projects is recycled.
