Q:How far is the sill of the upper window from the roof of the building?
V1 = 0 g = 9.8 t = 0.40 9 a million) locate D, distance from the roof to the bottom window, utilizing D = v1*t + 0.5 * a * (t^2), a = g ! 2) subtract 2.6 out of your D value, to get distance between roof and top window, and thats your answer !
Q:when a roof is pressure cleaned do the windows get dirty?
if your roof is regular mineral coated shingles i would NOT recommend pressure washing the roof,,,it will take off alot of the minerals and could shorten the life by many years,,if its dark from mildew there are chemicals to clean it with using a spray attachment and a garden hose
Q:White house with beige windows (outside) Black roof?
Try some grey browns or brown greys. Yes there are such things. Get some paint chips from a paint store and look at them next to a piece of white paper. To be able to see the brownness of a color hold the chip next to a pure grey or blue grey then the amount of brown in the paint will become apparent. Think of doing the front door too, if it's not a natural wood.
Q:Can I use screws instead of roofing nails in Jen weld vynil windows?
plastic windows are extremely temporary. i know i know there's some sort of long warranty but for real, they don't last very long THEY'RE MADE OUT OF PLASTIC!!! install em how ever you want. if you were building a house out of legos (i'm sure pulte or someone's already workin on that) then you could just snap em in. bad buy, too late, good luck! or should i say good luck to the next guy who buys your house that gets to replace the windows again.
Q:how can i bring fresh air into a closed room from the roof through the ceilings?
put an air vent in one of the walls with a fan
Q:we brought a new build house 4 years ago and all the ridge tiles on the dormer windows and roof ridge are?
No, this architect is not right. This is covered. Is the certificate from the RIBA? - if it is get in touch with them. You could go to go Citizens Advice Bureau or a solicitor if all else fails.
Q:New roof leaking on Cape Cod style home. Leaked in living room from high hats and around casement window.?
If you want to fix the leak then this may help. Often the problem with dormer window leaks is with the window sill fitting and window drain design. See my video on how to fix dormer window water leaks.
Q:Window A/C, roofing-ventilation importance?
there are a lot of factors involved in this it is called the envelope the infiltration of outside air vs inside air pressure in a nut shell the answer is it not practical to spend that amount for ridge vents or power ehauster
Q:Does the roof chimney calculate the building height
The height of the building refers to the total height of the building's exterior to the top of the wall. Should meet the following requirements: chimneys, lightning rods, flagpoles, wind directionors, antennas and other prominent structures on the roof is not included in the construction height. The horizontal projection area of the protruding part of the roof of the building, such as the staircase, the elevator tower, the decoration tower, the observation tower, the roof window, the water tank and so on, is less than 25% of the standard floor area and is not included in the building height and the number of layers. Flat roof houses according to the building outside the wall to the roof surface calculation, if the parapet, according to the height of the vertex of the parapet; slope roof buildings by the external walls of the building to the roof and roof height calculation. Calculation of slope at different slope in accordance with local regulations. According to the above provisions, roof tents probably can not calculate the building height.
Q:How much money would we save replacing windows and roof?
A 17 yr. old unit needs to be replaced regardless. Based on the sq. footage I would suggest you install 2 units if possible each rated at 1-1/4 ton or 15,000 BTU. If you insist on window units buy the highest seer units you can afford.
