For example,

the windows 7 ISO file is around 3.5GB. Yet when installed its around 10GB.

Is this because of compression,

Yes, it is because of compression. The data on the DVD/ISO are stored in a large file called install.wim. This WIM file is using the LZX compression algorithm to make it smaller.
