• The membrane should not be installed in adverse weather conditions. It must not be laid in rain, snow, or heavy fog, nor if the temperature falls below 5°C, unless precautions against condensation have been taken.
• Do not apply on wet or frozen surfaces.
• At falls in excess of 5° (1:11), precautions against slippage should be allowed and mechanical fixing should be installed.
• The membrane layers must always be installed with staggered overlaps and in such a manner that the laps fall in the direction toward the outlets.
• Attachment of reinforced bituminous membrane roofing may be achieved by full bonding, by partial bonding, or loose laid (ballasted) with guidance from danosa technical services; the choice should depend upon the type of substrate and the required resistance to wind uplift pressure.

For single layer application direct to deck:

• Deck surfaces must be dry, clean, and free from sharp projections such as nail heads and concrete nibs.
• When torching polydan directly to a suitable substrate, the substrate should be prepared using a primer; either bitumen primer hm, curidan, maxdan or maxdan caucho at the recommended rate prior to installation of the waterproofing system.
• Fully bonded torch-applied membranes should only be used with non-combustible substrates.
• For field applications:
  A: Roll the membrane into position, allowing for 80mm side overlaps and 100mm head overlaps and cut to length. All overlaps and cross joints should be staggered by a minimum of 300mm.
  B: Using a length of 100mm pipe (cut fractionally short of roll width) as an insert tube, roll back the membrane for a portion of the length (approximately 50%).
  C: Heat activate the membrane by torching in a vee area between the roll and substrate.
  D: Roll can be pushed forward by foot or by other suitable equipment. Apply downwards pressure when moving the roll to extrude a molten bead of bitumen from edges.
• For detail applications
  A: Place the membrane into position, allowing for 80mm side overlaps and 100mm head overlaps and cut to length ensuring all overlaps and cross joints are staggered by a minimum of 300mm.
  B: Heat activate the membrane by torching between the membrane and substrate.
  C: Apply pressure and consolidate the bond to the substrate, ensuring a molten bead of bitumen is extruded from the edges.

For system application including underlay:

• Fully bonded torch-applied membranes should be installed over non-combustible underlays.
• It is possible to install a torch-receivable underlay into hot bitumen, and then torch apply a capping sheet which should be specifically designed for torching, such as polydan. Bonding is achieved by melting the lower surface by torching and pressing the membrane down. Care must be taken not to overheat the membrane.
• For field applications:
  A: The cap sheet should be laid along the same direction as the underlay membrane, offset by a minimum of 300mm to ensure sufficient staggering of laps between layers.
  B: Roll the membrane into position, allowing for 80mm side overlaps and 100mm head overlaps and cut to length. All overlaps and cross joints should be staggered by a minimum of 300mm.
  C: Using a length of 100mm pipe (cut fractionally short of roll width) as an insert tube, roll back the membrane for a portion of the length (approximately 50%).
  D: Heat activate the membrane by torching in a vee area between the roll and substrate.
  E: Roll can be pushed forward by foot or by other suitable equipment. Apply downwards pressure when moving the roll to extrude a molten bead of bitumen from edges.

• When using a fully torched system, including glasdan 800 p perforado and esterdan 30p elast, see additional installation instructions within the appropriate datasheets.

Important details about this product:

Do you offer Free Delivery?

Yes! On most insulation orders over £350 Excluding Vat we can offer free delivery. However, this does depend on the delivery location and stock available. Sometimes stock may not be available at your local branch and may need to be delivered from a different branch which can alter the lead time or delivery charge. If this is the case one of our advisors will contact you to confirm any changes. Please feel free to send your enquiry over through get a quote or WhatsApp and we will work out the costs for you.

We always endeavour to have your order travel the least amount of miles to you in order to ensure free or the cheapest and most economic delivery option.

Orders below £350 Excluding Vat are usually subject to a delivery fee of £50 Excluding VAT on these items.

Where do you deliver to?

We can deliver these items to 99% of the UK population, utilising our various branches across England, Wales & Scotland.

To see if you are in our delivery area you can check the map below or find your postcode in the following list:
