This subject is dealt with very thoroughly in The Temple and the Church's Mission: A Biblical Theology of the Dwelling Place of God (New Studies in Biblical Theology) by Greg Beale.
From a Reformed perspective, the temple and tabernacle are interchangeable as the dwelling place of God. The curtain that was torn was the curtain into the Most Holy Place, the manifested presence of God, his throne on earth. (cf. 1 Sam. 4:4 Where God is 'enthroned between the cherubim' of the Ark.) Heb. 9:3 "Behind the second curtain was a room called the Most Holy Place". The first curtain separated the Holy Place, which was entered daily, from the courtyard.
The significance is awesome. After the fall, Adam & Eve were driven out of the original tabernacle - or divine dwelling - which was Eden. Before they were driven out, God promised a Savior who would undo the Fall (Gen. 3:15). God instructed Moses to build a dwelling place, but even then it was unapproachable except by the High Priest, one day a year. Reformed Theology has always understood the temple to be symbolic, and this symbolized that access to the presence of God was not yet available.
When Jesus came, God became flesh and made his dwelling among us, lit. 'tabernacled among us' John 1:14. When the body of Christ was broken, all separation was broken with it. We now, though vile, arrogant, and filthy, can enter the very presence of the Living God, and not just once a year but at any moment. This is exactly what Hebrews goes on later to say "Therefore, brothers and sisters, since we have confidence to enter the Most Holy Place by the blood of Jesus, by a new and living way opened for us through the curtain, that is, his body, and since we have a great priest over the house of God,let us draw near to God with a sincere heart and full assurance of faith." Heb 10:19-22
