UDL 25 Logo

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! end

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.

Titanium® UDL25 es una barrera contra el aire, el agua y el vapor (.06 perms), por lo que debe instalarse sobre espacios con una ventilación adecuada. Se recomienda seguir todas las normas de construcción de su región geográfica para su tipo de estructura.

PREPARACIÓN DE LA ESTRUCTURA DEL TECHO: Deben eliminarse las zonas salientes de la estructura del techo y esta no debe tener espacios vacíos ni áreas dañadas o sin apoyo. La superficie del techo debe estar seca y sin residuos ni humedad.

USO: El Titanium UDL25 debe cubrirse con el techado principal dentro de los 180 días posteriores a la aplicación. El UDL25 está diseñado para utilizarse bajo tejas sintéticas o de asfalto, techados de metal y tejados de cedro.

APLICACIÓN: El UDL25 debe instalarse de forma horizontal (paralela) al alero en techos con pendientes de 2:12 ó más, con el lado impreso hacia arriba. Los superposiciones horizontales deben ser de 4 pulg. (10.2 cm) y las verticales deben ser de 6 pulg. (15.2 cm) y deben estar ancladas a aproximadamente a 1 pulg. (2.5 cm) del borde. Con respecto a la aplicación en pendientes bajas, se recomienda sobreponer el 50% más 1 pulg. (2.5 cm); para conocer la definición de una pendiente baja y las directrices correspondientes, por favor consulte con las autoridades de su jurisdicción. El producto UDL25 no se recomienda en pendientes menores a 2:12. Pueden utilizarse martillos para techos, martillos tipo hacha y herramientas de fijación neumáticas de aire o gas. Se recomienda el uso de cortadores de borde recto.

FIJACIONES: Para cubrir el mismo día con techado primario, el UDL25 puede sujetarse con clavos para techo con cabeza de 3/8 de pulg. (9.5 mm) y 1 pulg. (2.5 cm) de largo que sean resistentes a la corrosión (es preferible usar clavos de cuerpo anillado, aunque los de vástago liso son aceptables). También es aceptable utilizar cualquier otro sitio para el anclaje que esté impreso en el producto. NO UTILIZAR GRAPAS: El uso de grapas para penetrar el UDL25 anulará la garantía.

ANCLAJE: Todos los clavos de anclaje deben estar al ras, a 90 grados con respecto a la plataforma del techo y ajustados a la superficie de recubrimiento y la estructura del techo. En los casos en que las uniones y juntas requieran de material sellador o adhesivo, se debe utilizar cemento plástico para techos con bajo contenido de solvente y que cumpla con las normas ASTM D-4586 Tipo 1 ó la Especificación Federal SS-153 Tipo 1, por ejemplo Karnak, Henry, DAP, MB, Geocel o equivalente. Otras alternativas aceptables son los selladores en forma de cinta o masilla con base de caucho butílico, uretano o EDPM.

EXPOSICIÓN PROLONGADA: Si el producto Titanium UDL25 va a estar expuesto más de 1 día pero menos de 5 días, se recomienda hacer el anclaje con clavos para techo con cabeza de 3/8 de pulg. (9.5 mm) y 1 pulg. (2.5 cm) de largo que sean resistentes a la corrosión (es preferible usar clavos de cuerpo anillado). Si el producto UDL25 se deja expuesto de 5 a 180 días, debe anclarse con clavos para techo anillados o lisos con tope de metal o de plástico de 1 pulg. (2.5 cm). También es aceptable utilizar placas de estaño o topes metal que estén aprobados en Miami Dade; se recomienda instalarlos con el borde rugoso hacia arriba para un mejor rendimiento. Para una exposición prolongada, se recomienda anclar todas las posiciones marcadas en el revestimiento. Nota: UDL25 no está diseñado para estar expuesto indefinidamente a la intemperie. En condiciones de exposición prolongada, donde se espera lluvia impulsada por el viento o ventarrones, se recomienda tomar precauciones adicionales como doblar el ancho de las superposiciones. De forma alternativa o adicional, podría utilizarse un sellador compatible entre las superposiciones, o bien, utilizar cinta adhesiva en las superposiciones.


En techos muy inclinados, se deben seguir las buenas prácticas de seguridad, como el uso de amarres, topes para apoyar los pies, escaleras y/o cuerdas de seguridad y arneses personales para el cuerpo. Siga las directrices de la OSHA. La resistencia al deslizamiento puede variar según las condiciones de la superficie, los residuos que se acumulen, el clima, el tipo de calzado, y la inclinación del techo. La falta de uso de equipos de seguridad adecuados puede dar lugar a lesiones graves. Según la inclinación y las condiciones de la superficie del techo, es posible que deba utilizarse algún mecanismo de bloqueo para apoyar los materiales sobre el techo, lo que constituye también una buena medida de seguridad. Recuerde que se deben sellar los orificios de los clavos después de quitar el mecanismo de bloqueo.

TitaniumMD UDL25 est une barrière contre l’air, l’eau et la vapeur (0,06 perm) et elle doit donc être installée au-dessus d’espaces bien ventilés. Il est recommandé de respecter tous les codes du bâtiment applicables à la région et au type de structure.

PRÉPARATION DU SURFACE : Les saillies de la surface du surface doivent être enlevées et le surface ne doit pas avoir d’interstices ni d’endroits endommagés ou non supportés. La surface du surface doit être exempte de débris, sèche et à l’abri de l’humidité.

UTILISATION : Le Titanium UDL25 doit être couvert par la couverture principale dans les 180 jours suivant sa pose. Le produit UDL25 est conçu pour être utilisé sous les bardeaux d’asphalte, les bardeaux synthétiques, les couvertures métalliques et les bardeaux de fente en cèdre.

APPLICATION : Pour les pentes fortes de 2:12 ou plus, le produit UDL25 doit être disposé horizontalement (parallèlement) par rapport à l’avant-toit, la face imprimée vers le haut. Les chevauchements horizontaux doivent être de 4 po et les chevauchements verticaux doivent être de 6 po et ancrés à environ 1 po du bord. Pour les pentes douces, il est recommandé de faire chevaucher de 50 % plus 1 po; pour voir une définition complète du terme « pente douce » et les lignes directrices à cet égard, veuillez consulter les autorités compétentes de votre région. Le produit UDL25 n’est pas recommandé sur les pentes de moins de 2:12. L’emploi de marteaux à toiture, d’un marteau hachette ou de cloueuses pneumatiques ou à gaz est acceptable. On conseille d’utiliser un couteau à lame droite.

FIXATIONS : Pour la pose du revêtement le même jour que la couverture principale, le produit UDL25 peut être fixé avec des clous de toiture de 1 po (tête de 3/8 po) résistants à la corrosion (clous à tige crantée privilégiés, mais des clous de toiture à tige lisse sont acceptables). L’usage de tout autre dispositif d’ancrage est acceptable sur le chantier. NE PAS UTILISER D’AGRAFES : L’utilisation d’agrafes pour installer le produit UDL25 annulera la garantie.

ANCRAGE : Tous les dispositifs d’ancrage doivent être affleurants, enfoncés à 90 degrés dans le surface, et ne pas présenter de jeu avec la sous-couche et avec la structure du surface. Lorsque les joints requièrent un produit d’étanchéité ou un adhésif, utilisez de la colle plastique pour feutre à faible teneur en solvant conforme à la norme ASTM D-4586 Type 1, ou à la spécification fédérale SS-153 de type 1 comme les adhésifs Karnak, Henry, DAP, MB, Geocel ou d’autres produits équivalents. Des solutions de rechange acceptables comprennent le butylcaoutchouc, l’uréthane et les calfeutrants ou rubans d’étanchéité à base d’EPDM.

EXPOSITION PROLONGÉE : Si le Titanium UDL25 doit être exposé à l’air libre pendant plus d’une journée, mais moins de 5, il est recommandé de l’ancrer avec des clous de toiture de 1 po (tête de 3/8 po) résistants à la corrosion (l’utilisation de clous à tige crantée est à privilégier). En cas d’exposition de plus de 5 jours, allant jusqu’à 180 jours, le produit UDL25 doit être ancré avec des clous de toiture à capuchon de plastique ou de métal de 1 po à tige lisse ou à tige crantée. Les rivets en étain ou capuchons en métal approuvés par Miami-Dade sont aussi acceptables, le bord rugueux face vers le haut pour des résultats optimaux. Dans le cas d’une exposition prolongée, il est toujours conseillé d’ancrer le produit sur chaque position imprimée de la surface. Remarque : Le produit UDL25 n’est pas conçu pour une exposition extérieure prolongée. Dans le cas d’une exposition prolongée ou de la pluie battante ou des vents violents pourraient survenir, il est conseillé de prendre des précautions additionnelles, comme doubler la largeur des chevauchements. Comme solution de rechange ou comme précaution additionnelle, vous pouvez utiliser un produit d’étanchéité compatible entre les chevauchements ou les recouvrir d’une bande adhésive pelée et collée.

MISE EN GARDE — VEUILLEZ LIRE LES CONSIGNES DE SÉCURITÉ CI-DESSOUS Adoptez toujours de bonnes pratiques de sécurité sur les toits à pente raide; par exemple, servez-vous de cordes de fixation, de planches cale-pied, d’échelles ou de cordes de sécurité et de harnais de sécurité individuels. Veuillez suivre les lignes directrices de l’OSHA. La résistance au glissement peut varier selon l’état de la surface, les débris qui y sont accumulés, les conditions atmosphériques, les chaussures utilisées et la pente du toit. Le fait de ne pas utiliser un équipement de sécurité approprié pourrait entraîner des blessures graves. Selon la pente de toit et l’état de la surface, un calage pourrait être requis pour soutenir les matériaux sur le toit, ce qui est une bonne pratique de sécurité. Souvenez-vous de sceller les trous des fixations qui ont retenu les cales après les avoir enlevées.
