Danosa Esterdan 30 P Elast Semi Adhesive Torch-On Underlay - 1 x 12m

Bituminous SBS modified membrane reinforced with a non-woven polyester felt. Combined underlay and venting membrane for partial-bond applications finished with easy peel polyethylene film finish.

Scope

• Bottom sheet in bilayer membranes for waterproofing roofs with semi-adhered heavy protection.
• Bottom sheet in bilayer membranes for waterproofing semi-adhered self-protected roofs.

Advantages & Benefits

• High movement capability.
• Modified with SBS polymers, it achieves much higher performance in behavior at high and low temperatures, elasticity and resistance to aging, which leads to improved durability of the membrane .
• Helps to increase the durability of the sheet.
• It retains its properties better over time.
• Good anti-piercing protection from mechanical damage.
• High tensile strength and high elongation at break.
• High resistance to tearing.
• High resistance to static and dynamic piercing.
• Rot-proof.
• Improves the performance of mechanically fastened sheets by providing a high wind suction resistance value and optimising the density of fastenings.
• Very stable in the long term.
• Weight: 36kg

Instruction for Use

• The substrate surface must be solid, uniform, smooth, cleaned, dry and free from foreign bodies.
• It is placed on the support by mechanical fasteners spaced approximately 20 cm. maximum.
• Danopol range is welded to the colaminated profile by hot air, resulting in high reliability welding and finish.

Indications and Important Recommendations

• Store in a dry place, protected from rain, sun, high and low temperatures.
• It should be kept in the sun for as short a time as possible to protect it from UV rays.
• In case of new construction and renovation, possible chemical incompatibilities with APP plastomer-modified bitumen sheets shall be taken into account.
• In case of refurbishment, chemical incompatibilities with old waterproofing systems consisting of PVC membranes, modified tar-based mastics or any other, shall be taken into account, and it may be necessary to remove them completely or to use suitable separating layers.
• If it is necessary to adhere to metallic or slightly porous elements, a bituminous primer (IMPRIDAN 100) shall be applied to the entire surface to be welded beforehand.
• Not suitable on flat roofs as permanent waterproofing layer.
• In case the substrate is a thermal insulation board, the compatibility between the two materials shall be verified.
• During cold weather, the substrate, if uncombustible, can be heated with the torch or other means.
• This product is part of a waterproofing system, so all the documents referred to in the Danosa Solutions Manual must be taken into account, as well as all the regulations and legislation that must be complied with in this respect.
• Exposure to the sun can make it difficult to remove the release film. The temperature of the membraneduring installation must not exceed 45°C.
• It must not be installed when the ambient, product or substrate temperature is below +10°C.
• There is no chemical incompatibility between the Danosa range of SBS elastomeric bitumen and plastomeric bitumen sheets.
• Not suitable as cap sheet on green roofs; use GARDEN variant.
• To join the transverse overlap at the ends of the rolls, it is necessary to preheat the transverse edge of the bottom sheet in a strip of 8-10 cm, remove the protective polyethylene film in the bituminous mass and then adhere the end of the next piece.
• Possible incompatibility between thermal insulation and waterproofing shall be checked.
• A separating layer (DANOFELT or DANODREN) must be laid before laying the heavy protection (paving, gravel, topsoil, etc.), except in the case of waterproofing under tiles.
• Polyurethane foam shall not be sprayed directly on top of the waterproofing without the use of a suitable separating layer (geotextiles, mortar layers, polyethylene film, etc).
• If expansion that could affect the sheet is expected, a separating layer shall be used between the sheet and the extruded polystyrene insulation boards, so that each product expands independently.

Maintenance Recommendations

• Please refer to DANOSA UK Technical Statement ‘Flat Roof Waterproofing – Cleaning and Maintenance Recommendations’
• Handling, storage and preservation
• Before moving the pallet, check the condition of the shrink-wrap and reinforce if necessary.
