vienkārši foliju var vienkārši saplēst. un tad tad vēl to šauro joslu kopā līmēšana. mēģināt var.
var.

Nē, nē ... es domāju celtniecības folliju. Tā ir diezgan plata un nav nemaz tik neizturīga. Nu, piem., to ko izmanto kaut vai saunu būvē.

noliec abas blakus

jā, jā ... skaidrs - spīdīgums (jeb pulējums)

Radiant barriers are materials that are installed in buildings to reduce summer heat gain and winter heat loss, and hence to reduce building heating and cooling energy usage. The potential benefit of roof space radiant barriers is primarily in reducing air-conditioning cooling loads in warm or hot climates. Radiant barriers usually consist of a thin sheet or coating of a highly reflective material, usually aluminum, applied to one or both sides of a number of substrate materials. See US Dept. Energy Insulation Comparison for a comparison with fibreglass batts.
Can have recycled content (but check!).
Its thinness makes it ideal for applications (eg refurbishment) where there is little room available within the construction to allow for more common insulation materials
Derived from non-renewable petrochemicals and aluminium
High embodied energy
Non-biodegradable
Poor airtightness
• Thermal resistance 0.45 - 0.80 m²K/W (BBA cert. No02/3947 for Apollo Thermofoil depending on application) (50mm Isowool glass fibre batt is 1.61 m²K/W)

Lai pārstātu darboties PIR sensors, tam priekšā nevajag foliju, bet pietiek ar sausām džinsa biksēm.
