“I called around to literally every glass shop in Portland and was truly blown away by Sierra Glass and how they conduct their business. I ordered a large piece of glass for our shower, a mirror, and frosted glass for LED lighting. Everyone I spoke to there was incredibly nice, polite and helpful. They had the best prices in town BY FAR - nearly half the price of some other local glass shops!
I spoke mostly to an awesome man named Vince who truly went above and beyond to make sure all my orders were ready in a timely manner. He was a fantastic communicator and made the whole experience super easy. They have gained a loyal customer for life with me, and I'll be recommending then to all my friends and family. I love Sierra Glass!”

What is Low-E glass?
Low-e stands for low emittance. All surfaces reflect, absorb and transmit heat energy or radiant heat to varying degrees.
Low-e glass was created to minimize the amount of UV (ultraviolet) and infrared light that passes through it while still allowing visible light through.
Why are Low-e windows popular?
Because they start paying for themselves immediately! Plus, they increase your comfort level. For example,you won’t get so hot when sitting by the window on a sunny day.
In addition, they prevents harmful UV rays from entering your home, which protects your window coverings, furniture and flooring from sun fading.
How does Low-e glass work?
Low-e glass has a transparent coating that’s microscopically thin (much thinner than human hair), which reduces the amount of heat transferred through it.
Thus, a low-e surface emits low levels of radiant heat meaning less heat is transferred through the window.
Save money year-round
In summer, Low-E glass reduces your cooling bills by blocking the sun’s radiant heat from entering your home.
In winter, Low-E glass lets the sun’s solar heat enter your home while keeping the heat inside the house from escaping and that results in smaller heating bills for you.
