Everything in your home that promotes insulation -- from drywall to windows -- is assigned an R-value. That rating tells you how well the item hinders thermal energy from going through it. A higher R-value and the object is a more efficient insulator.

So why should you care about a window treatment’s R-value in San Diego? Well, because your windows are one of the most common energy wasters in the house. If you have to keep in the warm air during wintertime or keep your rooms comfortable in summer, you will need a window covering with greater insulation. A window covering with a high R-value lets you keep your home at your preferred setting.

Every window covering is not built equally, and therefore different treatments will have different r-values. Though there may be a bit of variation from the material and craftsmanship between companies and models, below is what you’re likely to find when contrasting window coverings.

Only glass 0.75 - 1
Mini-blinds 1.5 - 2

Remember, the bigger the R-value number the more the window treatment insulates your window. It should come as no surprise that mini-blinds, which are made with inefficient aluminum, offer almost no energy-saving value when put up against a more weighty covering, like durable faux-wood shutters. That big gap in R-value can show up in a distinction of several degrees – enough to make an influence on whether you dial up the temperature and waste money or not.

What Are The Factors In A Window Treatment’s R-Value In San Diego?

Two things affect a window treatment’s R-value: construction and materials. First, treatments that have multiple ways for heat to escape won’t own a substantial R-value. For instance, blinds just hang there, letting heat to leak out around the bottom and sides of the treatment. On the other hand, interior shutters are custom-made to fit around the window pane, trapping heat against the window’s glass when the louvers are shut.

Secondly, what materials the covering is made out of can also bring a significant impact to insulation. Take cellular shades, which are made with several ​​engineered layers of fabric that create “cells” to trap hot air. As a result, they can stop air loss more effectively than treatments like Roman shades. Likewise, our Polywood plantation shutters, made from a solid faux wood composite, can repel heat more than natural wood shutters. Polywood shutters also use seamless weatherstripping, which makes a air-tight seal sound your windows when the louvers are shut.
