The only veracious record is in Josephus.
And it is big. About eighty feet high and twenty or so feet wide. But just for practical reasons it was probably made of the lightest stuff around. Probably more on the lines of a large flag than a thick woolen tapestry.
We construct negative air chambers for mold remediation (to contain mold spores) with heavy mil - plastic sheeting. It's surprising how much air pressure exists between outer and inner chambers.
From what I've read, the veil was around 4'' thick.
This website has two statements from ancient Jewish literature that describe the veil:
It was woven of seventy-two cords, and each cord consisted of twenty-four strands.
Just on a practical standpoint, looking at the Temple structure, when the outer doors were opened - wind would blow into that structure with great force. If the curtain was thin in structure it would in effect become a sail, fill with wind, and expose the Holy of Holies.
Which is counter to the protective worship prescribed by God:
(The veil) barred all but the High Priest from the presence of God, but when it was torn in two at the death of Jesus of Nazareth (see Mark 15:38), access to God was made available to all who come through him.” cbumgardner.wordpress.com/2010/04/06/the-thickness-of-the-temple-veil/
Only the High Priest was allowed into the Holy of Holies and then only once a year on Yom Kippur or the Day of Atonement to apply blood to the Ark. A rope was even attached to his body so that he could be pulled out from behind the veil should he die or collapse while in the Holy of Holies.
An interesting side point - I have to wonder what the High Priest was doing during the 2nd Temple Period - on the Day of Atonement. From what I've read, the Ark of the Covenant was not in the Temple. It has been hidden around the time of the Maccabees.
The prophet, being warned by God, commanded that the tabernacle and the ark should accompany him, till he came forth to the mountain where Moses went up and saw the inheritance of God.
And when Jeremias came thither he found a hollow cave and he carried in thither the tabernacle and the ark and the altar of incense, and so stopped the door. Then some of them that followed him, came up to mark the place; but they could not find it. And when Jeremias perceived it, he blamed them saying:
"The place shall be unknown, till God gather together the congregation of the people and receive them to mercy. And then the Lord will shew these things, and the majesty of the Lord shall appear, and there shall be a cloud as it was also shewed to Moses, and he shewed it when Solomon prayed that the place might be sanctified to the great God."
