Titanium® UDL25 is a highly engineered, mechanically attached, coated woven synthetic roofing underlayment for sloped roofs. UDL25 represents the future in felt replacement technology, and used in conjunction with Titanium PSU30 self adhered underlayment, offers the sloped roofing industry a truly revolutionary system of safety and security.

UDL25’s advanced polymers combine to deliver a unique gray synthetic roofing underlayment that can be used under all types of primary roofing materials to replace 30lb felt. Gray technology provides for a cooler working surface during installations and up to a 6 month UV exposure. Unlike smooth surfaced underlayments, UDL25 possesses a revolutionary patented slip resistant Sure-Foot® nodular walking surface technology that allows for easier steep slope walkability, even in wet or dusty conditions.

Gone are the days of blow-offs and call backs, since UDL25 is 14 times stronger than 30lb felt. UDL25 also offers big savings in time and labor as it is over 30% faster to install than felt! A 10 square roll weighs only 25 lbs! This low weight combined with 48” width and 250ft roll run length means fewer laps and cuts on every job. This ease of roll handling and reduced labour allows roofers to do more jobs in less time, inventory fewer rolls, and gain an edge in productivity and profits.

UDL25 is 100% synthetic and unlike oil saturated felt is unaffected by water. It is also inert to mold and mildew. It is engineered to lay flat and will not buckle or wrinkle when exposed to temperature and moisture fluctuations on the roof. UDL25 can be left on the roof uncovered without the need for tarps. Unlike oil saturated felts, UDL25 does not dry out, leach oils in the heat, nor does it become stiff, difficult to roll or crack in the cold.

The unique features of UDL25 combined with exceptional tear strength and up to 6 months exposure time allows your job to stay on track through all kinds of wind and weather. Less material damage and waste during installation and fewer post-install repairs result in significant savings in time and money. UDL25 will continue to provide a secondary layer of protection against leaks for you high quality, long life rated, primary roofing long after oil saturated felt products have turned to dust!

Installation Instructions

Titanium® UDL25 is an air, water and vapor barrier (.06 perms) and therefore should be installed above a properly ventilated space(s). It is recommended to follow all building codes applicable to your geographical region and structure type.

DECK PREP: All protrusions from the deck area must be removed and ensure the deck has no voids, damaged or unsupported areas. Deck surface should be free of debris, dry and moisture free.

USE: Titanium UDL25 must be covered by primary roofing within 180 days of application. UDL25 is designed for use under; asphalt and synthetic shingles, metal roofing, and cedar shakes.

APPLICATION: For slopes 2:12 and higher UDL25 is to be laid out horizontally (parallel) to the eave with the printed side up. Horizontal laps should be 4" and vertical laps should be 6"and anchored approximately 1" in from the edge. For low slope applications it is recommended to overlap 50% plus 1", for complete definition of low slope and guidelines consult authorities having jurisdiction. UDL25 product is not recommended for slopes less than 2:12. The use of a roofing hammer, hatchet hammer, pneumatic air or gas driven fastener tools is acceptable. The use of a straight edge cutting knife is recommended.

FASTENERS: For same day coverage with primary roofing UDL25 can be anchored with corrosive resistant 3/8" head x 1" leg roofing nails (ring shank preferred, smooth leg acceptable). The use of every other anchoring location printed on the product is also acceptable. DO NOT USE STAPLES: use of staples to penetrate UDL25 will void warranty.

ANCHORING: All anchoring nails must be flush, 90 degrees to the roof deck, and tight with the underlayment surface and the structural roof deck. Where seams and joints require sealant or adhesive use a low solvent plastic roofing cement meeting ASTM D-4586 Type 1, or Federal Spec SS-153 Type 1 such as Karnak, Henry, DAP, MB, Geocel or equivalent. Acceptable alternatives are butyl rubber, urethane, and EDPM based caulk or tape sealant.

EXTENDED EXPOSURE: If Titanium UDL25 product will be exposed longer than 1 day but less than 5 days then it is recommended to anchor using corrosive resistant 3/8" head x 1" leg roofing nails (Ring shank preferred). For exposure more than 5 days and up to 180 days UDL25 product must be anchored with 1" plastic or metal cap smooth or ring shank roofing nails. Miami-Dade approved tin tags or metal caps are also acceptable, and it is recommended for best performance to use with the rough edge facing up. For extended exposure it is always recommended to anchor on every printed position on the facer. Note: UDL25 is not designed for indefinite outdoor exposure. For extended exposure conditions where driving rain or strong winds are expected it is recommended to take additional precautions such as doubling the lap widths. Alternately or in addition to a compatible sealant could be used between the laps or a peel and stick tape could be applied to the overlaps.

Good safety practices should be followed on steep slope roofs, such as use of tie-offs, toe boards, ladders and/or safety ropes and personal body harnesses. Follow OSHA guidelines. Slip resistance may vary with surface conditions from debris that accumulates, weather, footwear and roof pitch. Failure to use proper safety gear can result in serious injury. Depending on roof pitch and surface conditions, blocking may be required to support materials on the roof and is good safety practice. Remember to seal the nail holes after removing blocking.

Instrucciones de instalación

UDL25 es una barrera contra aire, agua y vapor. Debe ser instalado sobre espacios ventilados apropiadamente (siga TODOS los códigos de construcción correspondientes a su zona geográfica y al tipo de estructura en construcción) ya que es considerado una barrera contra el vapor (0.06 permeable). El uso de una capa de papel colofonia rojo no es requerido debajo de los sistemas de techado de metal. Las protuberancias en la cubierta del techo necesitan ser removidas. La cubierta no debe tener vacíos, ni deterioros y tendrá que estar soportada adecuadamente. El uso de navajas de punta recta es recomendado. UDL25 bebe ser colocado horizontalmente (paralelo) al alero con el lado del logotipo hacia arriba y con una solapa horizontal de 4 pulgadas (101mm) y otra vertical de 6 pulgadas (152mm). Siga los códigos de instalación que han sido clasificados para pendientes bajas entre 2:12 y 4:12, y para pendientes muy inclinadas mayores a 4:12. Sujetadores: Si Titanium UDL25 se dejara expuesto por más de 5 días, el producto debe ser sujetado al material de la estructura de la cubierta del techo usando clavos de cuerpo anillado (preferentemente) o clavos de albañilería (aceptable) mismos que deberán tener una cabeza de plástico o de metal con un diámetro mínimo de 1" (25mm). El Condado de Miami-Dade ha aprobado como aceptable el uso de clavos para techos de cabeza delgada de estaño o de metal, con el borde áspero hacia arriba.

NO UTILICE GRAPAS: el uso de ellas en UDL25 cancelará la garantía del producto. Anclaje tiene que ser instalado en una como mínimo en las superficies impresas en el producto, espaciados 6 pulgadas (15 cm) entre centros en los tramos verticales y horizontales, y en 12 pulgadas (30 cm) a lo largo del centro del rollo en el campo. Si el contrapiso será cubierto por techos primaria dentro de los 5 días de la aplicación, y no están sujetas a un tráfico intenso o fuerte viento, a continuación, la opción de utilizar cada otro punto de anclaje impreso en el campo central es aceptable. Todos los dispositivos de anclaje tienen que estar al mismo nivel, a 90 grados de la cubierta del techo, ajustados al recubrimiento sintético y a la estructura de la cubierta del techo. En los meses de exposición prolongada y/o fuertes vientos, duplique como mínimo la anchura de la solapa. Alternativamente: doble la solapa sobrepuesta formando un canal de configuración "J" antes de clavar; utilice un sellador compatible entre las solapas o el empleo de una cinta autoadhesiva es altamente recomendado.

Para instalaciones aseguradas con tablones de madera, utilice únicamente clavos de cuerpo anillado o tornillos (preferentemente) que tengan una longitud adecuada; los clavos de albañilería son aceptables para asegurarlos a la estructura del material de la cubierta del techo. El uso de clavos para techos es requerido únicamente para asegurar UDL25 y combatir las ráfagas de viento hasta que el sistema de aseguramiento sea instalado. No coloque los tablones directamente sobre ningún clavo para techos. Si esto sucede remueva el clavo y coloque un parche en el orificio, reinstale otro clavo fuera de la estructura de aseguramiento y continúe. En las uniones que requieran sellador o adherente, utilice un cemento plástico para techos de alta calidad, de baja solubilidad, libre de asbestos; que cumpla con los requisitos ASTM D-4586 Tipo I (libre de asbestos) y especificaciones Federales SS-153 Tipo I (libre de asbestos) tales como Karnak, Henry, DAP, MB, Geocel o sus equivalentes. Como una alternativa aceptable usted puede emplear el caucho butílico, el uretano, la masilla selladora con una base de EDPM y una cinta selladora. Dependiendo de la inclinación de la cubierta y de las condiciones de la superficie del techo, puede ser necesaria la obstrucción para sostener los materiales colocados en el techo. UDL25 no está diseñado para ser expuesto al aire libre indefinidamente. El techo tiene que ser instalado en un plazo máximo de 6 meses.

ADVERTENCIA: LEA BIEN LAS SIGUIENTES PRÁCTICAS DE SEGURIDAD Al igual que como con cualquier producto para tejados, siempre deberá seguir los códigos y prácticas de seguridad (OSHA). Siempre utilice y vista los dispositivos para la protección de caídas cuando se esté trabajando en el techo. Tenga precaución al caminar o al estar de pie sobre UDL25 ya que la tracción puede ser reducida en condiciones de humedad y/o cuando haya exceso de polvo. La falta del calzado y del equipo de seguridad adecuado, pueden provocar lesiones graves.

Consignes d'installation

Pare-air / eau / vapeur. Le UDL25 doit être installé au-dessus d'espaces adéquatement ventilés (respecter toutes les directives des codes du bâtiment applicables au lieu et au type de structure) vu qu'il entre dans la catégorie des écrans antivapeur (0,06 perms). Il n'est pas nécessaire de prévoir une couche de séparation en papier à résine sous les couvertures métalliques. Il est recommandé d'utiliser des couteaux à tailler à lame droite. Le UDL25 est posé horizontalement, c'est-à-dire parallèlement à l'avant-toit, côté imprimé vers le haut, avec recouvrements horizontaux de 4 pouces (10 cm) et recouvrements verticaux de 12 pouces (30 cm). Il convient de respecter les directives des codes pour ce qui est de la pose sur les toitures-terrasses plates définies comme allant de 2:12 à 4:12 et sur les toitures à pente raide définies comme étant supérieures à 4:12. Le UDL25 doit être fixé aux panneaux de structure du toit au moyen de clous munis d'une bague de plastique d'un diamètre d'au moins 1 pouce (25 mm). Attaches : si vous laissez UDL25 exposé plus longtemps que cinq jours, le produit doit être fixé au matériau de sous-toiture de la structure à l'aide d'un capuchon en plastique ou en métal d'un diamètre minimal d'un pouce (25 mm) avec des clous à tige filetée (privilégié) ou des clous à pied lisse (acceptable). Les cosses en étain/capuchons en métal approuvés par Miami Dade sont acceptables, le bord rugueux face vers le haut.

NE PAS UTILISER D'AGRAFES : l'utilisation d'agrafes qui transpercent le UDL25 annulera la garantie. Les éléments d’ancrage doivent être installés au minimum selon les marques de la surface et espacés de 6 pouces (15 cm) au centre des recouvrements verticaux et horizontaux et de 12 pouces (30 cm) au centre du rouleau dans l’espace marqué. Si l'application d'UDL et le matériel final de toiture ont lieu dans 5 jours, et non-assujetti à une circulation dense ou à des rafales de vent, l'option pour employer chaque autre imprimée ancrant le placement est acceptable. Les éléments d'ancrage doivent être à niveau, enfoncés à 90 degrés dans les panneaux de toit, étanche avec la surface sous-couche et le support de couverture structurelle. Pour une exposition de longue durée (plusieurs mois) et/ou en cas de vent suffisamment fort pour faire soulever le produit, doubler au minimum les largeurs de recouvrement. Facultativement, il est possible de plier les surfaces de recouvrement pour obtenir un canal en « J » avant de clouer. L'utilisation d'un matériel d'étanchéité compatible avec le produit ou de ruban adhésif entre les parties se chevauchant est fortement recommandé.

Pour les installations à liteaux, n'utiliser que des clous ou des vis de longueur adéquate pour fixer les baguettes de bois aux panneaux de toit. Les clous ne sont nécessaires que pour éviter que le UDL25 ne s'envole et pour le maintenir en position jusqu'à l'installation du système de liteaux. Ne pas installer les baguettes de bois directement sur les clous. Si tel était le cas, retirer les clous, boucher les trous et remettre les clous hors de la zone de pose des baguettes. S'il est nécessaire d'utiliser un produit d'étanchéité ou un adhésif sur les joints et les raccords, utiliser une colle plastique pour toitures de très bonne qualité, à faible émission de solvants, exempte d'amiante et conforme aux normes ASTM D 4586 Type 1 (sans amiante) et Federal Spec SS 153 Type 1 (sans amiante) telles que Karnak, Henry, DAP, MB, Geocel ou équivalentes. On peut également utiliser un produit de calfeutrage à base de caoutchouc butyle, d'uréthane ou d'EPDM ou encore une bande d'étanchéité adhésive. En fonction de la pente du toit et de l'état de la surface, des cales peuvent être nécessaires pour étayer les matériaux de toiture.

UDL25 n'est pas fabriqué pour une exposition d'une durée indéfinie à l'extérieur. La toiture finale devrait être installée avant six mois.

Comme avec tout produit de toiture, suivez toujours les pratiques de santé et sécurité au travail (CSST) et utilisez et portez toujours l'équipement de protection individuelle lorsque vous travaillez sur les toitures. Faites attention lorsque vous marchez ou vous tenez debout sur la membrane UDL25 dans des conditions humides et/ou poussiéreuses qui peuvent réduire la traction. Négliger d'utiliser les chaussures et l'équipement de sécurité appropriés peuvent causer des blessures sérieuses.
