What to Look for in Windows

window installation renosWindows are a crucial fitting for any house, and choosing the right windows for your house can save you a lot of time and money. In addition to bringing light and fresh air into a house, windows are responsible for keeping the heat in and burglars out so you can keep yourself from calling up a Denver criminal defense attorney. These are important factors to consider when making a choice about which windows to purchase for your property.

Energy Rating System

The Energy Rating system measures a window’s solar heat gain, heat loss through glass and frames, and air leakage. A good energy rating will make your house significantly more energy efficient.


You will have probably heard of double glazing before now. A window’s glazing refers to the number of panes of glass used in the window’s makeup. The space between these panes insulates heat and noise and offers greater protection from the elements. Double glazing is important to ensure toughness and good energy ratings – consult with your painters on this.

Visible Transmittance

Depending on where your fixture is going to be or where you live in the world, you will need varying levels of visible transmittance. This refers to the amount of visible light that can pass through a window, with lower numbers indicating less visible light passing through.

Solar Heat Gain Coefficient

The Solar Heat Gain Coefficient (SHGC) is an important factor to consider when you require your window to offer cooling. This measure indicates how efficiently a window blocks the sun’s heat, with a lower SGHC denoting superior blocking.


The R-Value denotes how resistance the window is to heat flow, and provides a good measure of the window’s insulation. A better R-Value could save you a lot of money in energy bills.


The U-Value is another rating that is helpful in saving you energy costs, as this is the rating that denotes the window’s overall prevention of heat loss.

Condensation Resistance

Condensation can be very irritating and can often cause visual disturbance to the window, impeding one of its most vital functions. The measure of condensation resistance indicates how well a window resists the formation of condensation on a scale of one to one hundred, with higher numbers donating superior resistance.
