Ubiflex non-lead flashing Ubiflex is a non-lead waterproof flashing material which can be used in most applications where lead is traditionally used to provide a weatherproof junction at features such as changes of direction and materials. Ubiflex is manufactured by coating both sides of an aluminium mesh reinforcement with a mixture of modified bitumen and additives. The underside of the product is finished with a kraft paper and film backing. Colour granules are added to the surface, the material cooled and rolled into the required lengths.

effeCTive, aTTraCTive roof deTailing – wiThoUT The CoMProMises Use Ubiflex wherever you used to use lead! Ubiflex is malleable like lead, allowing it to be formed into an infinite variety of shapes, to form: ■ ■ ■ ■ ■ ■ stepped flashings abutment flashings chimney flashings pitched roof valley liners dormer window flashings rooflight and solar panel flashings No scrap value means no risk of theft spiralling costs of metals have led to a huge increase in thefts of lead from buildings. This has in turn caused increased insurance premiums as well as huge inconvenience during remedial work. Ubiflex...

The Ubiflex sysTeM – seTTing new sTandards in flashings Ubiflex is: Up to 50% quicker to install than lead, is fully malleable, can be worked in both directions and is self-sealing if punctured. Modified polyethin compound with an aluminium mesh reinforcement Temp resistance: not susceptible to thermal movement. aprons up to 12m long can be formed without seams or expansion joints - 8 times longer than traditional lead sheet. Consequently, there is less wastage with Ubiflex. by hand: -10°C with lead dresser: +5°C Use warmed material for improved malleability at low temperatures Compatible with...

design gUidanCe General when designed and installed in accordance with the relevant parts of bs 5534:2014, bs 6229:2003 and bs 8000-6:2013, Ubiflex is suitable for use in flashing applications, such as abutments, chimneys, saddles, valleys and dormers to provide a weatherproof junction. Unlike lead, Ubiflex can be used for long runs of up to 12m when used as a dPC or a cavity tray in masonry walls. in addition, Ubiflex is resistant to the corrosion which affects lead when portland cement containing free lime comes in contact with moisture so there is no need for additional paint protection. Ubiflex...

Fixing Ubiflex into a wall or chimney Without a DPC on upstands, parapets, chimneys and walls without a damp proof course (dPC), Ubiflex should be turned into a joint or chase by not less than 30mm. Ubiflex should then be held in place with Ubiflex fixing clips, spaced not more than 450mm apart and then the joint filled with Ubiflex gap-seal (figure 01). Ubiflex gap-seal has been designed to resist the cracking associated with mortar and protect the joints from water penetration. With a DPC when installing Ubiflex in a joint which includes a prefitted dPC, the mortar should be removed to a depth...

Flashing to a flat roof upstand figure 04 flashing to a flat roof upstand figure 05 flashing to a side abutment - double lap tiles/slates Ubiflex should cover the upstand by at least 75mm and be sealed to it with a continuous bead of high-Tack sealant. (figure 04). where double lap tiles or slates abut a wall they should be covered with Ubiflex stepped cover flashing (figure 05). The height of the upstand should be at least 150mm. The Ubiflex stepped flashing should be 150mm wide, cover the soakers by not less than 65mm and be sealed with a continuous bead of Ubiflex high-Tack.

Flashing to a wall or chimney: side abutment – single lap tiles for single lap tiles a continuous Ubiflex cover flashing can be used (figure 06). This flashing should go up the wall 150mm (as double lap) and cover the tiles by at least 150mm (200mm for deep profiles or pitches below 25° in exposed areas) and be sealed with a continuous bead of Ubiflex high-Tack. figure 06: flashing to a side abutment – single lap tiles alternatively, single lap tiles can be weatherproofed at abutments by using a cover flashing and a separate stepped flashing (figure 07). as in double lapped tiles, the cover flashing...

Flashing to vertical tile and slate hanging Ubiflex should be taken behind tiles by not less than 75mm and finished with a single weathercheck welt (figure 10 and below). in slate hanging the Ubiflex extends 100mm behind the slates without the welt. alternatively, soakers and a cover flashing can also be used in this instance and should follow the same procedure as shown in figure 05 (see page 07). at the junction of the tiles/wall/cill, a separate cill flashing is required. This cill flashing extends up the wall at least 75mm and is chased into the brickwork minimum one course above the tiles...

Pitched valley lining Ubiflex is suitable for use in a valley gutter with all types of roof covering and boarded, battened and counterbattened roofs (figure 12). Ubiflex sits directly on the valley boards - these should extend at least 225mm each side of the centre of the valley and include tilting fillets positioned 150mm each side of the centre. when the tiles/slates are laid the gap between then should not be less than 125mm. valley boards (not less than 19mm thick) are laid on top of the rafters in boarded and counterbattened roofs or fixed flush with the top of the rafters in battened roofs...

Supply, handling and storage Ubiflex rolls are supplied packed individually in boxes and should be stored in a dry area. no special handling is required during storage or installation. Ubiflex is non-toxic and recyclable. Installation Ubiflex can be worked in the same way as lead, but without the need for any protective measures. Ubiflex can also be used in direct contact with any building material, including copper, zinc, iron, aluminium and stainless steel, in most climate conditions and environments. Ubiflex: ■ Can be cut with a sharp knife ■ Can be fixed with stainless steel nails if required...
