Hollow Doors- General Budget & Finance

I just read an article by an energy company auditor. He stated that hollow core doors between a heated area and the outside can add as much as $40 to $50 a month to your heating bill. This was rather surprising but makes sense if you think about it.

    Between a warm house and an unheated garage would be another place where you could lose a lot of heat. And what about the attic door - if it is inside the house? Warm air rises. It could rise right up thru that door. Not exactly sure how you could take care of that - maybe some kind of insulating blanket to pull over the opening before lifting the door back up. Little light bulbs are starting to light up!!!. . . . .This same auditor said if you added all the leaks and weak places together it COULD add up to a 6 sq. ft. to 10 sq. ft. hole in the side of your house. This seems a LITTLE far fetched to me but that's what he said.

    Haven't even thought about this one.
    And what about the attic door - if it is inside the house?
    and this one also

    warm house and an unheated garage would be another place
    Ok now you have me thinking as well.. How many people have pet doors? There goes the heat or air conditioning.

    Most places now have to follow code for doors for attached garages which is they must be fire rated metal doors ..

    If you have the solid wood doors with panels these are almost useless - pretty but the panels have very little R value .. mine actually would get frost on it ..

    Leaks add up (6sq ft is only a hole that is 2x3), when you think of all the places cold comes in, its not hard to imagine it totaling a small window.

    Anything you do today will be better than nothing and today it will be cheaper than next winter (I doubt the price of caulk or anything else will drop). When the wind picks up go around with a candle to the exterior doors, windows, outlets .. Check the trim around the doors and windows too.

    Pipe insulation (flat comes in a skinny rolls) is great for stuffing in around windows and doors (use a putty knife)

    While winter is still happening for some of us, some are moving into warm weather .. insulating and correcting the drafts and holes will also help with cooling later ..

    EXTERIOR DOOR REPLACEMENT
    Standard doors are an easy swap out to insulated metal .. You will need to pull the old door framing because wood will shift to fit the change in building and the metal door will be square (90*) .. Dry fit the door framing and door (yes keep them together) you will need at least 2 people.. Check for level, both ways .. Make sure you use shims (I buy a bundle of wood shingles and have shims forever) to keep door straight and true .. You then need to screw the door frame to the house frame ... push in insulation and caulk, put on trim .. On the outside use exterior caulk - I personally would not use glue on the underside of trim to house in case you have to remove it (royal pain)

    INSULATING ATTIC DOOR:
    if this is a pop up style ..make sure you have enough insulation in attic .. then buy some styrofoam insulation cut to size of door attach to the door (there are glues that can be used) .. personally I like the 2 inch with the foil because it doesn't get as damaged but reg styrofoam would work too

    door/stair combo: these are harder to do but not impossible .. bring up light and have someone shut the door/stairs how much does it stick out above the exsisting joists? .. you will be making a frame that will extend past this area **don't forget to take some batting and go up the sides) .. then take a 1/2 sheet of ply that will fit over the opening (maybe screw on some handles for ease in moving) add the styrofoam .. place on opening and adjust then close the door ..

    My brother is building a house, and this is a super idea.
    styrofoam insulation
    This is really neat stuff. I couldn't figure out what it was for--because I had never saw it before. And I got him to explain this item to me..Very new to me & interesting..

    We don't use hollow core doors anywhere in the house for security reasons. Not only do they let a lot of air in, someone breaking in can smash right through them. If you have a fire, the hollow core door goes up in flames quickly. a sold wood door takes longer and burns much slower giving trapped person time to get out a window or through a wall.

    Hollow core doors are a tad better than some of the new doors that are made of hard board (think of peg board backing).

    We have had over 30 kids through the house, every inside door will need replaced because of dents, holes etc. I also need to rebuild the wall around the basement stairs because Matt literally tore the door off the wall/framing (kicking etc started the process).

    Now that we are down to one kid (Jake, bio and no mental health issues) I would love to put in the wood doors but not sure financially I can swing it.

    One of my doors at the apt building is old old solid door and its not standard size 39 inches wide .. replacement was going to be anywhere from 6-800 without the frame .. I ended up having my son replace it with a metal 36 inch door (he lives rent free so figured he could do it instead of Mom)

    if you have the flat solid doors these can weigh a lot, you need to make sure your studs will handle the weight especially for kids doors that get slammed .. do not use dry wall screws they will NOT handle the stress ..

    Charlie Wing (Mainer) designed a wood door with insulation using T & G that I personally think is pretty as well. I would like to modify it for the exterior basement door which has an opening of more than 48 inches (I put in double doors). He wrote a couple of books, I have one I think in the basement I need to pull it out and check it out for other ideas.

    RE FOAM & STYROFOAM INSULATION:

    FOAM INSULATION: There supposedly is a DIY foam insulation kit online .. (this is like the spray can foam) .. Messy I will bet, and not sure if there is a smell while using .. also wonder about the toxicity when burned

    STRYFOAM SHEETS white - different thickness are availiable
    these are great for windows too .. Back when we first got the house they had 1/4 gaps (6 ft wide windows) I cut foam into 3 sections to put up in the window at night or when we were gone or crappy days, made a HUGE differance on the heat.. when the day was crudy there was a glow coming through the foam so it actually looked nicer than it really was (weather wise)

    at camp the trailer settles so lots of gaps at doors etc - the secondary door I put strofoam up and put duct tape around each piece so it would hold up .. *numbered them so I can put them up quick each year too) .. we could get out in case of fire but its warmer

    STYROFOAM FOIL BACKED. I know this comes in different thicknesses.. I had some thin stuff maybe only 1/2 inch thick and I have had 2 inch with very dense foam

    STYROFOAM PACKING BEADS, WORMS ETC ..
    You know I bet these could work for some areas ..

    Great ideas and ways to save on the electric bill. We have a sliding glass door on the back of the house. I really don't like it myself. In the winter I have to pull the blinds to keep the cold out, and in the summer because of the heat. I would like to replace it, I do believe that it would help with the drafts. It's nice to have I guess, but I haven't seen anything about it that I really like. Or we could build a roof over the patio, that may help some in the summer time from the heat.

    SLIDERS:
    Do you use it in the winter? If not make a lined curtain use a shower rod for top and bottom .. When you make the curtain I put the rod about 3 inches from the end this way the 'ruff' seals the top and the bottom

    If you need it to open then sew on some fishing weights to the bottom so it stays down.

    I used old blankets to do them up at camp but you can buy a new acyrilic blankets and use fabric that coordinates with the room for the side that shows .. If you have animals I would use a white sheet, blanket then the fabric otherwise the cat/dog hair will be all over the bottom side of the blanket .. (sheets don't attract it like the blanket)

    Ria, you have given me a great idea on this. I wonder how well a shower curtain would work. Now days they are made of heavier material, many different colors to choice from, and easy to hang up. I've used curtains before and hanging them can be tricky sometimes. With a shower curtain I can hang them with the rings, easy to slide for when the dogs need to go outside. Thanks for the idea on this.
    I do like the idea of useing a shower rod to keep the curtain down and closed. That would be a great thing to make for the bedrooms. We don't open our windows much in the winter, so it would work out great on that. You have inspried me today Ria, thanks for the great ideas..........my light bulb is light up bright.......lol.........funny how the simplest things can work so well.
