Because black surfaces absorb sunlight and convert it to heat. You don't want to accumulate that heat inside the house, usually. Of course, this assumes that you don't install and remove the covering daily. You could also use aluminum foil and avoid most of that issue. However, check where the light shining on your window will reflect to before using ...

The purpose is to allow natural light into the room. Generally these room-to-room windows are used for rooms which have no external wall, and so cannot have a “normal” (outside) window. The risk of someone “spying” on you through a window is true for all windows. Although hopefully you trust the people who live in your house more than the general population, ...

You will almost certainly save $100 on your heating costs by using film, assuming you install it well and stop drafts through the window seals. It may also make the home feel more comfortable, which can be the primary benefit. Also, properly installed film is virtually invisible. You hardly know it's there. In my former home here in Minnesota we put the tape ...

Even if the windows were super thick, it wouldn't be strong enough to handle the pressure exerted by a properly positioned ladder. A ladder is supposed to be sloped 25%, like this: With someone standing near the top of the ladder, that means roughly 20% of his weight is directed as lateral force, directly into the wall or window, conveyed by the points of ...

We were all young once. You need a Torx screwdriver of the appropriate size https://en.m.wikipedia.org/wiki/Torx Actually due to the pin in the middle it is more technically security Torx. Harbour Freight will get you out of trouble cheaply.

Looks like fungus of some sort. It grows on many surfaces. Try household cleaners and a sponge. There are many types of mold, and the hysteria surrounding them is often unwarranted. Mold spores are everywhere, and only a very specific type is potentially dangerous, and only in significant quantities. The term “toxic mold” is not accurate. While certain ...

Don't do it. Put the ladder above the window, then clean by putting your arms through the rungs. Shouldn't the windows have a way to tilt them inward and clean from inside the house? Most every modern window I've seen has a way to do that. You may want to get a ladder stabilizer:

I have personally seen it bow "trimmer" studs in a framed window opening. It could easily warp, bow, or move a window frame itself. Breakage would likely be caused by users messing with/forcing the out of plumb/square/true window? Note: you can buy "low expansion" foam specifically designed to avoid this issue.

You could just chill out. Putting up bars or plastic on that door is truly ghetto. Doors like this are not inherently unsafe at all. Your door is appropriate for your neighborhood. Your door would be unsafe or inappropriate for a bad neighborhood or an apartment building. Having this glass probably does not effect your chances of burglary by ....

Window insulation film. https://www.youtube.com/watch?v=gwkmgbzGG-g This window kit is clear plastic sheeting. You attach it with double sticky tape along all edges. When I did this the last step was to blow hot air on it with a hair dryer which got rid of wrinkles. 3M makes a kit. The plastic must be something like shrink wrap but I dont know if that ...

Film in Nebraska would likely be worth it, at least for the worst offenders in terms of drafts. A tight storm window can boost a single-pane's R-value from 0.9 to about 2.0, which is actually comparable to many double pane windows. Coated storm windows can also drastically lower emissivity (by 75%) over plain glass ones, which helps a lot aside from R-values....

In my last house, (in U.K.), I took out a stramit block wall from a bedroom, and replaced it with thermalite blocks. Since the bedroom was dark-ish, I built a narrow double-glazed strip (something like 18" x 6') into the top of the wall. It could have been frosted glass - but even my bathroom windows were clear. That was into a corridor where there was ...

Yep, looks like you hit it with Preston type, it's a screw drive that pulls the window in like a hopper window. Behind the cross-shaped part with the screw (threaded section) should be a part that spins on the threads and walks the upper assembly out, pulling the window along the screw. I'd get up there and remove the hardware and clean it up, since it's ...

In the cases where I've run I to something like this, the hotel originally had open walkways around the rooms -- allowing more light in, and probably cheaper to build -- which were later closed off with an outside wall to provide a sheltered approach to the rooms and to reduce energy needed to heat or cool the rooms. The windows were left in place because ...

It does work better to have them outside. The filtering in the bags + window after is better than window + bags. I have actually tested this. Outside though like Ed mentions, really really hard to secure these. Inside they can kind of smell and it looks really bad - sunlight heat sits between bag and window. Those are your main pros/cons. If this is long ...

Air has pretty good insulation value if you can stop it from convecting. If it convects, it transfers heat fairly efficiently. Fiberglass and rock-wool matt rely on this - the point of the strands is to create boundary-layer effects that prevent the air from circulating. That's why compressing fiberglass makes it insulate worse. Too wide a gap between ...

You could consider attaching a thick acrylic or other plastic panel that covers the interior of the glass and is firmly screwed to the door. The edges can then be covered with molding. Such plastics are shatter resistant. While they can be broken, they will not yield to the tools of most casual home intruders (unless they carry sledge hammers or blow ...

Either use a A frame ladder or a squeegee on a pole. I personally wouldn't trust my health on the structural strength of glass.

You're dealing with a basic fact of nature, water condenses on cold objects, so you need to either remove the water or the cold objects. The windows will typically be the coldest objects in your home since they have such a low R value. Start by reducing the humidity in your home, run exhaust fans in the kitchen and bathroom for longer when cooking and ...

Clean it up with bleach and a sponge (chlorine is the main ingredient of mold-cleaners). If your home is humid (RH >55%) consider installing a dehumidfier so with less moisture you get less mold.

To add to @matt's answer, it is specifically for extra natural light in otherwise dark corridors. In a small British terraced house, there is generally a corridor between rooms on the first floor to allow access to bedrooms, bathrooms etc, without having to do through another room. This is common in Victorian (1800s) and Edwardian (early 1900s) terraced ...

I had a similar problem. It was easy enough to remove the window, and take it to my local glass shop. They had a new pane put in by the next day. If it's a screened window, you can do this when the weather is nice. Otherwise, you'll need to cut a piece of plywood to block the hole while it's being repaired. Taking it into the shop allows for ...

A 0.0025 inch thick sheet of any solid has negligible R-value in-and-of-itself (for purposes of home insulation). The (relatively) calm air next to it does have some R-value, on the order of R 0.7. Heat flow is calculated using conductivity (U-value). U-value is the inverse of R-value. R-value has units of (square foot)(hour)(Fahrenheit degree)/(British ...

Yes, but you'd need to repurpose existing common studs as jack studs. This may mean using a wider (longer) header than would ordinarily be needed. Obviously this means opening up the wall more than you'd maybe like, but it's all kept up above the tub where it's more easily repairable. _________________________________________________ ...

From my days installing car film, I have two basic suggestions. Get off the floor. You can't work down there without dust being blown into your workpiece every time you move. Get up on a table in a room without a lot of human or pet traffic, where the air remains still. Most installations are on the window in a wall anyway. Use plenty of solution. You don'...

If you are doing this for blocking light I would possibly do something different. I used aluminum foil. I applied it with a water sprayer on the glass and wiped it down. It only had to be taped at the edges and the window could still open. If you want to open the window or door, often 1/2 the glass being sealed on the inside and the other half on the outside ...

Tubular skylights, a suntube in use and available from Solatube. There's roofing and carpentry involved but no framing needed. They're the only way to have a skylight with an attic above without blowing out your ceiling. Cut 2 holes, flash it to the roof, enjoy.

First, kill the mold with bleach and wipe down the whole area to try to get rid of as many spores as possible. Next, identify and treat the root cause. Mold at the bottom of the inside would suggest that interior condensation is pooling there. Window condensation is caused by two factors: Interior glass temperatures below the dew point Humid enough ...

That's a window sash lock. It's designed to prevent someone from defeating the lock from the outside, or prevent a small child from opening it from the inside and falling out. Operates as any normal window sash latch would, only you have the option to lock it with a key as well. Personally, I consider it a death trap. If locked, there's a fire, and that's ...

This is indeed black mold. We had the same problem at home because: A vent is built between the shutter box and our bedroom. The shutter box wasn't insulated at all: the lath was cold and had a large surface in a small volume. It was basically a perfect condenser. Our HVAC wasn't properly set up and the mechanical ventilation wasn't strong enough to stop ...
