Eaves Box End

The versatility and range of FloPlast profiles and accessories allows an extensive choice of detail and appearance when dealing with box ends.

The illustrations detailed show some of the industry standard arrangements. Provision should be made for supporting all free edges of the box ends and box end returns as well as soffit boards. Treated softwood battens, securely fixed or tied back to the main structure, will provide a suitable means of support.

Box End Detail 1

This detail shows Ogee Board fascia, and bargeboard cut from a section of fascia. The box end is usually deeper than the normal fascia run, because of this we offer our 454mm Universal and 404mm Mammoth boards in 1.2 mtr lengths.

Use corner joints at the front and the back of the box end, and close the back of the box with a section of fascia (if this is deeper than the fascia, use the material supplied for the box end section) this should be slightly deeper than the measured height so that there is no gap between it and the bargeboard soffit.

Cut the rear corner joint to suit.

Where the back of the box end exceeds 300mm use the double ended 500mm Corner joint.

Mitre the soffit at 45° and the soffit joint trim (RT20) at both ends.

This detail shows the bargeboard extending to meet the fascia. A triangular fillet cut from a suitable piece of FloPlast board is set above the bargeboard, and fixed with FloTop nails to the tilt fillet on the gable rafter, another fillet, with either the return leg intact or removed, is fixed with FloTop nails to timber framing supported by the gable ladder, if the return leg is removed the bottom cut edge is protected by attaching a Board End Moulding.

The triangular off cuts may be closely butt jointed and finished with low modulus silicone to the top and bottom edges of the bargeboard.

FloPlast Decorative Bargeboard Moulding

The FloPlast Decorative Bargeboard Moulding offers style and character to most roofline installations. Once installed, it will require very little maintenance, as it will not rot, warp or require painting.

A variety of patterns can be achieved at the bargeboard apex.
A finial joint is now available to add that extra touch of elegance to your home.

Decorative Moulding Installation

Measure the length of your bargeboard and calculate how many mouldings are required at 500mm per moulding, making an allowance for design and plumb cuts at the ridge and barge ends.

Cut to size and screw using four 15mm x 6 self tapping screws, to the underside of the existing FloPlast PVC-UE bargeboard. Seal the joint between the moulding and bargeboard with either a low modulus silicone, or an appropriate adhesive.
