Question:
Which way up should SuperFOIL SFUF be installed?
Answer:
The branded foil side, with the protective polythene layer, should face up into the room.
Question:
What tape should be used with SuperFOIL SFUF?
Answer:
SuperFOIL Superior Tape can be used for sand cement screed applications and any other uses such as window reveals, wrapping steels etc. If using a liquid anhydrous screed, a good quality 100mm wide non-foil tape should be used.
Question:
Can SFUF be installed directly under screed?
Answer:
Yes, SuperFOIL SFUF includes a protective layer of polythene which separates the insulation layers from the screed. All seams should be butt-jointed and sealed with tape to create a continuous barrier. If a liquid anhydrous screed is to be used, extra care should be taken to prevent the screed from coming into contact with the screed to prevent the foil reacting with the screed. SFUF can be used under screed applications and many other uses such as window reveals, wrapping steels etc.
