  2. Background SelfAdhesiveapplications are notalways easy toapply NUROOF “futuristic” conceptwill PROBABLY havetouse self adhesivesolutionsbecauseitwillnotbebitumenbased Thereforeitcouldbeinterestingto demo test the self adhesiveapplicationalsoforConcept n. 1 PartnersDellacasa and Imprima areconstructioncompanies They can test NUROOF samplesforconcept n. 1 in June They can givegoodhints on applicationguidelines and evencontributeto the R&Ddevelopment IN THIS PRESENTATION DELL AND IMPRIMA GIVE THEIR FIRST HINTS AND ARISE SOME QUESTIONS ON SELF ADHESIVE APPLICATIONS But FIRST GUIDELINES AND WARNINGS SHOULD ALSO COME FROM ALL OTHER PARTNERS

  3. Advantages / ProblemsofSelfAdhesiveMembranes There is an ASTM International standard written specifically to address self-adhesive membranes installed beneath exposed roofing materials (widely used as ice dam protection at eaves). This standard is ASTM D1970, “Standard Specification for Self-Adhering Polymer Modified Bituminous Sheet Materials Used as Steep Roofing Underlayment for Ice Dam Protection”.

  4. step 1: logistics • Howwill the productbedelivered, rolls? • Weightof the roll: doesitfollowstandards? • Lenght : max5-7 m

  5. step 2: storage, transport 1) Are therespecificissuestoconsiderfor NUROOF concept 1 and 2? 2) And regarding self adhesive (rain, snow,…)?

  6. Step 3 preparation NewRefurbishment Do weneed a primerfor self adhesives? Whichmaterials? Are theysafe? What are the cleaningguidelines?

  7. Step 4 choiceof self adhesiveaccordingto material and surfaceconditions

  8. Step 4 SuggestedtableforguidelinesN=new, M=medium, O=old

  9. Step 4: do wehavetoexcludethisifweuse self adhesive? • Fibrous material • woodbased • rock wool • Porous material, weak material, inconsistent

  10. Step 5: unrolling Are therespecificguidelinesfor the unrollingphase? How do I unroll the self adhesive?

  11. Step 6 : application • Can weapplywhencold? • In case ofmistake do wehavetimetoadjust? • Whenit’s totallybonded, can weeasilyrepairit? • Can we complete bondingbycompression? • Can weeasily cut itwithcutters?

  12. Is the membrane enoughflexibletowithstandstructuralstrains due tonormaladjustments or evenlittleeartquakes? Is the membrane enoughflexibleto go aroundvents and chimneys? Howtoprevent air bubbleswhileapplying membrane?

  13. Conclusions: the best membrane from the applicationpointofview
