What does a green shield mean on Reddit?

The green tack means the post is stickied, meaning it will always be at the top of the subreddit until un-stickied. The green shield is a mod distinguished comment. NSFW means the content may be Not Safe For Work or inappropriate for some audiences. (

What do the Reddit icons mean?

A blue, microphone-like icon / A blue [S] means that the user that commented is the person which posted the post. A green, shield-like icon / A green [M] means that the user is the subreddit’s moderator. A red, Reddit logo-like icon / A red [A] means that the user is a Reddit admin, an employee that works on Reddit.

What does the golden lock mean on Reddit?

It means that the moderators have locked the post and no-one is able to comment on it. This usually happens with threads that are about a polarising topic and many people break rules commenting on it. Sometimes the thread gets locked for other reasons (i. e. when something on r/whatisthisthing is identified)

What does R and U mean on Reddit?

/u refers to a username and links directly to a users profile. For example, you are /u/Vegeta4461. /r refers to a subreddit and links directly to the subreddit.

What does R mean in a URL?

It’s just the first part of the URL: /r/something/ . – Shomz Jan 5 ’15 at 3:26. it means exactly that, “/r/”. you didnt tell us what “action” is, but if action = “images/bla.jpg” for example, then url = “/r/images/bla.jpg” – cari Jan 5 ’15 at 3:26.

What does R mean slang?

R means “Are”.

Whats the difference between R and U?

Here are the differences in a nutshell: U-value (also known as U-factor) is a measure of heat transfer (heat gain or loss through glass), while R-value is a measure of heat resistance….Categories.

Property	U-Value	R-Value
Lower number is better	Yes	No
Higher number is better	No	Yes
Included in NFRC Labeling	Yes	No

Are higher U-values better?

The units of measurement for thermal transmittance are m²K/W and, again, a higher figure indicates better performance (in contrast to the lower figure desired for U-value).

What is the U value in glass?

U value is the measure of the insulating capacity of the glass. This represents how quickly heat from hot air (not direct sunlight) will pass through the glass. The lower the U value the better the insulation. For example, 4mm clear float glass has a U value of 5.9, whilst ComfortPlus™ has a U value of 3.6.

What is U-factor and R-value?

U-factor or U-value is also referred to as the overall coefficient of heat transfer. A lower U-value indicates better insulating properties. R-Value equals a measure of the resistance of the glazing to heat flow. It is determined by dividing the U-value into 1, (R-value = 1/U-value).

What is a good U value?

The best insulating materials have a U-value of close to zero – the lower the better. Building regulations currently stipulate that for a new building, the elements must have maximum U-values as follows: Wall – 0.3 W/m2k. Roof – 0.15 W/m2k.

How do you calculate R and U value?

To calculate R-value, divide 1 by the U-value figure. For example, a U-value of 0.10 equals an R-value of 10 (1 divided by 0.10). To calculate U-value, divide 1 by the R-value—a 3.45 R-value equals a U-value of 0.29.

What is the best U value insulation?

The best currently available is the Val-U-Therm system (available from Scotframe) with a U value of 0.09W/m2K from a wall thickness of 235mm, plus the outer skin. Changing the 140mm mineral wool in a timber frame to 140mm polyurethane would give the same U value as a SIPs panel.

Is the lower the U value the better?

U-values measure how effective a material is an insulator. The lower the U-value is, the better the material is as a heat insulator. Thermal performance is measured in terms of heat loss, and is commonly expressed in the construction industry as a U-value or R-value.

What is the U value of a wall?

Domestic. * A U-value of 0.55 W/m²·K is used for cavity insulation and 0.30 W/m²·K for internal or external wall insulation.

What is the minimum U value for walls?

England. * A U-value of 0.55 W/m²·K is used for cavity insulation and 0.30 W/m²·K for internal or external wall insulation.

What does W m2K mean?

A U-value is a measure of thermal transmittance, or the amount of heat energy that moves through a floor, wall or roof, from the warm (heated) side to the cold side. It is the number of Watts per square metre of the construction, per degree of temperature difference between one side and the other (W/m2K).

Which windows are most energy-efficient?

Energy-Efficient Glass Dual-pane glass insulates almost twice as well as single-pane, while triple-pane glass maximizes your energy efficiency. Inert argon gas can be used between panes of glass to improve insulating properties and help reduce thermal transfer.

Is triple glazing worth the money?

Well the cost of triple glazing is a fair bit higher than double, whilst the improved U-value is not very large. If you are getting your windows done anyway, or you are building a new home, triple glazing is not a bad idea, but if you already have double glazing, triple glazing might not be right for you.

What is the most energy-efficient glass?

Stanek Comfort-Gard

Are Andersen Windows better than Pella?

When a home with Pella windows is sold, the materials warranties are still equal to or better than Andersen material warranties in all lines but Renewal. The fact that Andersen does not cover labor in most warranties is a clear advantage for Pella.

Can you negotiate with Window World?

Negotiate a Lower Price Every replacement window company—even authorized dealers— will negotiate prices. While you should feel free to propose a different price or some extras, keep in mind that every replacement window company will have its own negotiation stop point.
