Installation suggestions for putting EVII over a slab & Under carpet. EVII is NOT allowed under carpet in Canada.
We recommend a high R-Value carpet pad of at least 3/8" to 1/2". They have better R-Value than TSheet does. 1/2" Prime urethane (R-2.15) and 1/2" Bonded Urethane(R-2.1) are good choices.
