Draft at doors can be stopped with weatherstripping productsMost heat goes through the ceilingAre you on top floorre: attic above? If so, add insulation in atticAsk landlord before doing any work.
Well a better way to insulate a apartment is utilizing carpet, weather stripping for the windows and heavy curtains.Trust me it helps quite a bitAlso, if you have a fireplace, burning logs can help a lot tooBut, using a electrical or gas heater can bring up the bill.
Block construction is extremely difficult to insulate, because concrete has practically no insulation value itself, and even if they filled the cavities inside with insulation, there's not much room and most of the space is still taken up by the concrete, insteadElectric heat is generally more expensive than gas heat to operateYour landlord isn't much help because he's heard similar complaints every winter for as long as he's owned this rotten buildingYou can move to warmer quarters if you feel like itThis building isn't going to improve much.
The plastic window shrink wrap works very well, you can buy big packs of multiple window sizes at Walmart and most other department storesMeasure your windows, so you know what you are looking forIt comes with double sided tape and you place it on and shrink it tight with a regular hair dryer set on lowI live in New England, and oil is through the roof, so we purchased one of those electric heaters that look like a wood stove to supplement the heat with, it will heat the central part of the house and only adds a few dollars a month to the electric bill, which is a lot cheaper than the oilWe saved about three hundred dollars in oil last winter by using it and lowering the oil heatWe also lower the heat when we are not home, our home is well insulated, and only takes a few minutes to warm up when we get home in the eveningWe have planned on putting in programmable thermostats in the spring, we had other household expenses this fall and will deal with setting them manually until thenMake sure that your pipes in your basement or crawl space are insulated and also get a water heater blanket, that will help retain water temp and keep your pipes safe from freezingYou can make your own draft dodgers, with tube socks and rice, although the crafted animal figures with long legs are cuteYou can get templates for homemade draftdodger animals on the Good Housekeeping and Martha Stewart sitesThere are foam plates that you can buy that actually fit into your outlets and will cut down on a lot of drafts, all you have to do is remove the switch plate and put the foam insert into the opening on top of the outlet and then replace the switch plateYou can go onto the Home Depot, Lowes or Sears websites and get more information on insulating and money saving tips for the heating seasonGood luck, Happy Holidays and stay warm.
A box beam is a hollow rectangular (or square) cross-sectioned beamMeaning it has two flat horizontal plates attached to two vertical platesCantilever means it is fixed at one end only, like a diving boardNot sure of exact uses but is more resistant to twisting and sideways buckling than an I-Beam, and is generally more resistant to bending than a solid beam of equal weight (depending on its height to width aspect ratio) As for how much bending stress it can withstand, that depends strongly on the dimensions of the beamThe bending stress is given by: StressMy/I M is the calculated bending moment y is the distance from the neutral axis I is the moment of inertia, which for a box beam is: I[(B-b)(h-h)^3]/12 Where B total width b hollowed section width H total height h hollowed section height The maximum stress should be less than the yield strength of the material being used.
