Metal Fascia & Gutter Systems
Fascia, Barge and Fascia Cover
METAL FASCIA, the modern, good looking economic alternative to timber, forms part of a total system of rainwater goods such as Roof and Wall Cladding, Gutter, Capping, and Downpipe but can be used with any type of roof and gutter system.
It is straight, true, shrink and warp proof and is made from an aluminium/zinc alloy coated steel which gives years of life. METAL FASCIA is used as both Fascia and Barge and is mounted on adjustable pressed steel brackets using a very simple fixing method. METAL FASCIA COVER is also available which can be used to reface timber fascia which has deteriorated.
ADVANTAGES
COST SAVINGS
METAL FASCIA is continuously roll formed from light gauge coil steel and therefore has low initial cost. Labour savings in erection time are also made because the rafters do not require trueing and the METAL FASCIA is quickly and easily installed. Because of the protective coating there is very little cost involved in maintaining METAL FASCIA as it lasts years without being touched.
PROTECTION
Zincalume® and Pre-painted Zincalume® coated steel provides the best protection from the environment and gives long life to any building.
SOFFIT APPLICATION
METAL FASCIA is installed exactly level and the height and distance from the wall can be adjusted so that standard width Soffit Lining can be used without any trimming. The groove in the rear of the METAL FASCIA is used to retain the outer edge of the Soffit Lining and thus there is no trim piece required.
GUTTER APPLICATION
Gutter brackets for Square or Quad Gutter can be easily attached to the front face of METAL FASCIA either by sliding the bracket tongue through the raised slots and bending over at the correct height, or by screwing or blind rivetting in position. Gutter fall can easily be allowed by sloping the line of brackets along the METAL FASCIA.
SUPPORT RECOMMENDATIONS
MAXIMUM SUPPORT SPACINGS
METAL FASCIA shall be supported by a bracket at every rafter or at a maximum of 1200mm between brackets.
ACCESSORIES

RECOMMENDED FASTENERS
Brackets to Timber Rafters: No 10 x 25 Wafer Head Type 17 Self Drilling Screws or 30 x 2.8 Galv. Clouts. 3 Fasteners per bracket are required.
INSTALLATION
PRINCIPLE
Once the roof trusses and rafters have been assembled the METAL FASCIA is then installed ready for the gutter to be added. The Rafter Brackets have been specially designed to aid quick assembly and have slots for both horizontal and vertical adjustment as well as holes for nailing to timber rafters or rivetting to metal rafters. It is not necessary to cut the end of the rafters.
PROCEDURE
FASCIA
Work on each straight run in turn.
1. Mark the position of the brackets on the two end rafters.
Note: The top of the Fascia should be located as follows:
Metal Roofs - 2mm (Min) below the roof sheeting.
Tile Roofs - 35-65mm above the top corner of the rafter.
2. Run a stringline between the two end rafters on the vertical line. (String not to touch other rafters.)
3. Mark vertical lines on the other rafters using a bevel set at the roof pitch.
4. Fix 2 Rafter Brackets to the end rafters on the marked lines.
5. Run a stringline between these brackets attaching at the soffit groove on each.
6. Add intermediate brackets sufficient to support the fascia. These must be on the vertical lines and the stringline.
7. Cut the length of fascia on the ground. Prepare mitres and splices if required.
8. Lift the prepared length of Fascia up to the brackets, hook the bottom onto the brackets and spring the top over the top of the brackets.
9. Add the remaining brackets. Twist the brackets into the back of the Fascia. Slide along and hold against Rafter. Nail or rivet to the Rafer, ensuring the Fascia is straight and the front face is vertical.
FIXING FASCIA COVER
Fascia Cover is used to reface timber fascia and is simply placed over the timber fascia and fixed with a clout in every second rafter. The same accessories as for Barge can be used to finish off.
BARGE
Install Barge in a similar manner to Fascia. Except the Brackets are bent at right angles along the line of slots. In this case all brackets are axed on and the barge sprung on last. Methods of fixing barge are as follows.
Cut both ends of the barge at an angle to suit the pitch of the roof. A Barge mitre is used to finish the joint between the barge and the Fascia.
At the roof apex the 2 Barge lengths are joined by leaving a flange on one which inserts into the other and is secured by blind rivets.
JOINING SLEEVES
Slide one end of the internal Joining Sleeve into one length and then slide the second length over the other end. The External Joining Sleeve is then used to cover the join.
FASCIA BARGE MITRES
The Internal Mitre and Internal Mitre Angle are used to form internal corner joints and are fixed with blind rivets. External corners can also be made using the External Mitre. Alternatively, mitre the length of Fascia/Barge, bend to 90 degrees, and secure with blind rivets.
