Question:

My guesthouse ceiling is open beam/bare boardThe sides of the structure are only 6 ft and it peaks at 10 ft.?

We are located just east of Los Angeles and in summer it gets over 100 degrees inside So, we want to put insulation between the 4quot;X2quot; beams that run every 22quot; or soThen attach drywall directly to the beams so as to keep the peaked roofThree questions: 1) what is the right insulation to use that won't go past the 4quot; beams yet do the job and 2) can I use 1/4quot; thick drywall or do I need 1/2quot;? And 3) Since there is no attic, how do I get rid of the accumulated heat near the ceiling? The a/c is big enough for a 600 sq ft room, yet the guesthouse (once a pool house) is 400 sq ft and even with the thermostat set at 78, it never shuts off or gets cool enough.

Answer:

Tell us the makes and models your routersAlso tell us what's connected to what.
Its an EA 6500 by Linksys and I have two smart TVs, a blue Ray, two computers and two cell phones connected but they are all connected automaticallyThe cameras maybe a little older and they have their own internal address of 192.168.1.108 that must be accessed before changes can be made to their internal addressThey wont work if they are on different segmentsI have tried readjusting my ip address at the router but I did this at work where I have one router connected to another, I will try what Tumbleweed suggested tonight at home where I only have one router connectedHopefully, the router will accept what I put in, and I have been trying 192.168.1.1 with a subnet mask of 255.255.255.0 I believe that address will put me in the same segment as 192.168.1.108?
I am an HVAC tradesman and understand insulation very wellI have seen houses with your type of roof/ceiling and have seen them enclosed for the very same reasonIf it were my ceiling, I would put batting insulation in between the beamsR11 is the best you will get in that 4 spaceI would then put Celotex over the beams on the entire ceiling and then 1/2 or 5/8 drywall over the CelotexThe reason for the Celotex is twofold: 1) if you only put insulation and drywall over the beams, heat will conduct right through the roof, into the beams, then into the drywall and in short time will discolor any finish you put on it showing the beams above2) the Celotex will offer a little bit more R-Value to the total ceiling envelope and save you on your electric billThe other option is to re-roof the space and put the insulation on the roof meanwhile keeping the beautiful type ceiling you have in your guesthouseIn that case, I would consult with the roofer for the best insulation options.
