layfastSBS Roofing Underlayment For Tile, betway live casino login and Metal Roofs

LayfastSBS - Superior Elastomeric Modified Asphalt Underlayment for Tile, betway live casino login , and Metal Roofs

Most of the quality tile, betway live casino login , and metal roofing manufacturers offer 30+ year warranties - these usually cover deterioration of tile and betway live casino login only. Since the underlayment is the only moisture barrier used in the assembly, employing an inferior underlayment with a shorter life expectancy will compromise the system’s integrity.

Addition of SBS rubber to asphalt gives betway live casino login an elastomeric property that is not available in common felt. betway live casino login SBS contains a higher percentage of asphalt for increased waterproofing. Its inorganic fiberglass reinforcement eliminates the rot and deterioration associated with saturated felt.

The majority of architects and contractors have realized the necessity of a better underlayment, such as self-adhesive membranes, for valleys and eaves. Most self -adhesive membranes are manufactured with SBS-modified asphalt, which is the same compound used in betway live casino login SBS. By specifying betway live casino login in the field and a self-adhesive membrane in valleys and eaves, you are specifying a 100% SBS underlayment system throughout the roofing system and prolonging the waterproofing capability. In contrast to self-adhesive membranes betway live casino login is mechanically fastened, thus allowing the system to breathe.

betway live casino login SBS . . . Superior to Felt. Here’s Why:

• Versatile:
  ASTM D226, ASTM D4869, ASTM D6757 & ICC Approved (Report #4083). .

• Warranty:
  betway live casino login is backed by 10, 20 and 30 year material warranty.

• Steep Slope (Limited Material Warranty):
  betway live casino login 10 year limited material warranty. One layer of TULF40, TU35 or supercap SBS.
  betway live casino login 15 year limited material warranty. One layer of TU43.
  betway live casino login 20 year limited material warranty. Two layers of TU35 or TULF40.
  betway live casino login 30 year limited material warranty. Two layers of TU43 one layer of TU70.

• Economical:
  For pennies more, offer a superior product to your customer. Typical increased cost to use betway live casino login in place of felt is about >107_word_end<.02->107_word_end<.08/square foot.

• Less Decomposition:
  Fiberglass reinforced (inorganic) does not rot like felt. Felt is reinforced with recycled paper - and you have seen what happens to paper products, like newspaper, after they are left out in the weather.

• More Elastic:
  SBS rubberized asphalt provides a more pliable and elastic membrane. Minimizes buckles and wrinkles by laying flatter and smoother . . . saving time.

• Durable:
  Side laps do not curl up over time. Does not scuff or tear easily and is less susceptible to damage from other trades.

• Proven Track Record:
  betway live casino login has been used successfully for more than 20 years.

betway live casino login SBS is available in three weights.

For Architects and Specification Writers
Since betway live casino login is still mechanically fastened (like 30/40# felt), there is no change in drawings/specifications. To specify betway live casino login , insert the following language in thetile/shingle/metal roof specification section where the underlayment is specified. For tile and metal roofs, we recommend the use of TU70; for shingle roofs, we recommend the use of TU43.

Underlayment shall be LayfastSBS TU70/TU43, as manufactured by MBTechnology (800-621-9281). The membrane shall comply with all requirements as outlined in ASTM D226 standards for underlayment and approved by ICC. Application shall be done in accordance with manufacturer’s most recent specification manual. Minimum requirements:

Safety Consideration:
Contractor shall observe all safe roofing practices as required by OSHA and local codes. Use caution when walking on steep slope especially when the surface is slippery and dusty. Failure to use required safety gear, footwear and equipment can result in serious injury.

Placing material and tile on roof:
Certain tiles with minimal contact with surface of betway live casino login SBS may be prone to sliding especially when temperature is over 100 (F). Appropriate measures such as installation of a batten system, reducing number of tiles will address this issue. Contractor shall also use roof jacks, toe board or storage platforms secured to the underlying roof deck to prevent slippage of stored roofing materials.

Compound:
SBS Rubberized Asphalt

Reinforcement:
Fiberglass Mat

Weight:
Minimum of 43-70 -lb./100 sq. ft.

Breaking Strength:
MD 65 lb./in. ASTM D226, CD 46 lb./in.
