Turning a three season porch into more of a four season porch with out spending a lot of money. Being able to insulate to keep heat from escaping quickly.

Thanks, Mary

Hi Mary,

I’m assuming you want some information on how to best insulate your room to maximize its comfort and extend its seasonal use.

A lot depends on what part of the country you live in.  Visit the web site: for information on what type of insulation you should use for the for the climate zone you reside in.  Remember to caulk around any cracks, windows and doors.  Air infiltration can be very detrimental to maintaining a comfortable room.  As you add insulation, you will need to provide some sort of ventilation of the insulated areas.  This might include your crawl spaces and attic area.

Are your windows and doors at the maximum energy rating?

How does the room sit relative to the sun?

Will you add any kind of heating device or cooling device?

Here is one other web site to check out for insulation and moisture control: http://www.ornl.gov/sci/roofs+walls/insulation/ins_05.html.

Good luck.
