I've been renovating my homes for years, mostly by the seat of my pants.
This forum seems like a great way to learn about new products and pick-up advice that can save time and money.
I'm using HVAC Eng as my label because I've worked as a consultant and facilities engineer in this field for over 30 years.
Sometimes some of the smallest renovations cna be the most interesting or challenging. I am planning to build a 5' by 12' addition onto my dining room and then build a new 15' by 9' three season room onto the enlarged dining room.
My issues for this addition is reroofing a low-pitch roof (1.5:12) and putting a radiant heat floor system throughout the enlarged dining room.
