Have you ever was in between making decision to cap or not to cap your wood windows?
Or you are making your mind right now if you should or not to make this to your windows.

Thank God you are reading this, therefore you will have on honest opinion on it.

What is capping?

In construction capping or window capping (window cladding, window wrapping) refers to the application of aluminum or vinyl sheeting cut and formed with a break to fit over the exterior, wood trim of a building. The aluminum is intended to make aging trim with peeling paint look better, reduce future paint maintenance, and provide a waterproof layer to control the infiltration of water.

Therefore it seems obviously, that capping should protect your window frames and sells, practically it has opposite effect.

However it is really good idea to do this when you have vinyl window install, a lot of contractors picked up this practice for wood and half wood windows, what actually not protect them, but destroy them.
Capping is really popular in some regions, especially in Philadelphia area.

As homeowners we all looking for ways to save money on a lot of things around the house. Although there is some stuff can not be safe on. Your wood windows are required constant maintenance, painting, cleaning, checking on rotten parts etc. Sometimes it is a little overwhelming, for homeowners, so capping comes in handy, because you can simply cover window and forget about all maintenance and work that should be done on windows.

But for how long?

In a long run you will pay more for fixing problems that capping will create.

You see, when you have your wood windows wrapped, you can not see what is going on under it. Wood as natural material what has to “breath”. When wood is cover with vinyl or metal it is disposed to sunlight during the day and it’s cooling down at night time, what naturally create moist between wood and capping material.
