Hy­dro­safe high-per­form­ance va­pour re­tarder, suit­able for all fibrous in­su­la­tion mats and boards

 

Advantages

  • The best pos­sible pro­tec­tion for in­su­la­tion struc­tures thanks to hu­mid­ity-vari­able dif­fu­sion ad­apt­a­tion with a vari­ation of a factor of over 100
  • Test win­ner in April 2012 with the Ger­man product-test­ing found­a­tion »Stif­tung War­entest«
  • For con­struc­tion in ac­cord­ance with stand­ards and laws, thanks to ap­prov­al by the Ger­man DIBt
  • Per­man­ent pro­tec­tion: Of­fi­cially tested and cer­ti­fied per­form­ance
  • Pro­tec­ted winter build­ing sites thanks to hy­dro­safe be­ha­viour
  • Low­est VOC rat­ing in haz­ard­ous sub­stance test
 

Application

Can be used as a va­pour check and air­tight­ness mem­branes for all ex­tern­ally dif­fu­sion-open struc­tures, e.g. with roof un­der­lay (pro clima SOLI­TEX), soft­wood fibre­board or MDF board. For a high level of pro­tec­tion against mois­ture in­duced fail­ures in struc­tur­ally chal­langing con­struc­tions such as dif­fu­sion-res­ist­ant flat/pitched roofs. Also suit­able in ex­treme en­vir­on­ments such as in high moun­tain re­gions. Fur­ther in­form­a­tion is giv­en in the study “Cal­cu­lat­ing po­ten­tial free­dom from struc­tur­al dam­age of thermal in­su­la­tion struc­tures in tim­ber-built and steel sys­tems”.

pro clima INTELLO should be laid with the side with the plastic film (the printed side) facing the installer. They can be laid flat either at right angles to or along the sub-structure (such as the rafters) without sagging. If laid horizontally (at right angles to the sub-structure) then the maximum space permitted between the rafters is 100 cm (3'3"). After laying, it is necessary to support the weight of the insulation with lathing on the inside. The laths should be no more than 50 cm (1'8") apart. If, when using insulation mats and boards, for example, you expect tension as a result of the insulation weight on the adhesive tape joins, an additional supporting lath should be placed on the overlap. Alternatively, the adhesive tape can be reinforced along the overlap by sticking strips of adhesive tape at right angles to the overlap every 30 cm (1 ft).

Airtight seals can only be achieved on vapour control membranes that have been laid without folds or creases. Ventilate regularly to prevent excessive humidity (e.g. during the construction phase). Occasional rush/inrush ventilation is not adequate to quickly evacuate large amounts of construction-related humidity from the building. Use a dryer if necessary.

To prevent condensation, INTELLO should be stuck down so that it is airtight immediately after installing the thermal insulation. This particularly applies when working in winter.
