Everything in your house that plays a part with insulation -- from the walls to windows -- is assigned an R-value. That rating represents how well the item prevents thermal energy from flowing through it. A bigger R-value indicates a better insulator.

But why should you worry about a window treatment’s R-value in Phoenix? It just so happens that windows are one of the biggest energy wasters in your house. If you want to trap in the heat during the cold seasons or keep your house comfortable in summer, you will need a window treatment with greater insulation.

Remember, the larger the R-value number the more efficient the window covering. It shouldn’t be a shock that mini-blinds, usually made of inefficient aluminum, bring almost no energy-saving value compared to a more weighty covering, like faux-wood shutters. That big difference in R-value can result in a difference of several degrees – enough to make an influence on your decision to change the temperature and waste money or not.

A couple of things affect a window treatment’s R-value: form and materials. To start with, coverings that have multiple paths for heat to escape won’t own a large R-value. For instance, curtains and blinds don’t firmly cover the window, letting heat to escape around the sides of the covering itself. On the other hand, interior shutters are custom-built snuggly around the window pane, trapping heat against the window when the louvers are shut.

Then what materials the product is made out of can have a big impact to insulation. Take honeycomb shades, which feature overlapping layers of fabric which make “cells” to trap air. As a result, they should stop temperature loss more efficiently than products like pleated shades. Likewise, Polywood plantation shutters, made from a solid faux wood polymer, can repel heat loss more than more porous wood shutters. Polywood shutters also employs seamless weatherstripping, which creates a air-tight seal sound your windows when the panels and louvers are completely shut.
