Title of Question:
Insulation
Name:Noah Quinn City: Oviedo

| Question: I'm wanting to covert a portion of the attic to a small bedroom. The roof system could best be described as a flying rafter type. The only insulation in the attic is between the celing joists of the first floor. I would like to place insulation between the ceiling panelling (that I'm going to install) and the rafters. Do I need to keep a gap of air between the decking of the roof above and the ceiling panelling attached to the joist? If so, how much air space? The boards for the rafters are 2" x 14". Also, do I need do place some holes for ventilation in the bridging between the rafters? I'm worried that warm air will not be allowed to circulate. |
Post Your Answer To The Question Above:
| Answer: When installing the insulation, you want to have it fit snugly in the cavity without compacting it (which reduces the insulating qualities). You don't need to leave any other gaps, as long as you have a vapor barrier on the insulation. Always put the vapor barrier toward the warm side of the insulated area, which means downward on the attic floor or to the inside of the wall. Regarding the other moisture question, your best bet is to install roof vents 2-4 depending on the size of the attic) to help with air circulation. I hope this helps.
