Attaching conservatory to a SIP house

[KimFB]

Hi All,

 

We moved to a new SIP house a few months ago, and we are now planning to add a conservatory off our kitchen to bring outside in. We've chosen and placed an order with one of the larger installers in our area who allegedly claim that they have experience working with sip houses. But we are kind of nervous whether they really understand SIP construction and know how to securely fasten the conservatory to SIP exterior wall. Pics attached for reference.

Could anyone please advise whether this is a relatively straight forward process or are we potentially placing the structural/functional integrity of our SIP house in jeopardy?

Thank you
