Q: What’s the most cost-effective way to insulate windows?

• <div><p>If you have bubble wrap lying around the house and you don&rsquo;t care about the odd look, taping bubble wrap over a window is a very affordable way to insulate it. Another inexpensive option for insulating windows is to add new caulk around the glass. This step quickly cuts down on air drafts for older windows, and a tube of caulk only costs a few dollars. Adding plastic shrink film around the glass is another cost-effective option. You can purchase a kit of plastic film for a few dollars per window.</p></div>

Q: What are the most energy-efficient windows?

• <div><p>ENERGY STAR&reg;-certified windows are the most energy-efficient windows on the market. This certification means that the window meets strict efficiency guidelines set forth by the Environmental Protection Agency. While they might cost more upfront, they can save you money on your energy bills in the long run. ENERGY STAR&reg;-certified windows lower household energy bills by an average of 12% annually.</p></div>

Q: How can I darken my windows without curtains?

• <div><p>To darken your windows without curtains, try installing window film or even installing an awning outside your windows. Window film is a DIY-friendly option with many different darkness levels you can choose from to fit your desired look. Awnings can also help by casting shade over your window, though this isn&rsquo;t feasible for every home. </p></div>

Q: What is the most energy-efficient and insulating window treatment?

• <div><p>Cellular shades, also known as honeycomb shades, are the most energy-efficient and insulating window treatments. Their honeycomb structure is made of soft fabric that forms layered cell pockets. These pockets trap air, creating a thermal barrier that reduces heat loss in the winter and blocks heat gain in the summer. For even greater insulation, consider double- or triple-cell varieties. Side-tracked cellular shades, which seal the edges of the window frame, can further minimize air leaks and maximize energy efficiency.</p></div>

Q: How do you black out a window cheaply?

• <div><p>You can easily and cheaply use tin foil or cardboard to black out your windows. Save a pretty penny by cutting either material to the size of your windows and taping it to the window. This is one of the easiest and most budget-friendly blackout solutions, but it definitely isn&rsquo;t the most aesthetically friendly. </p></div>

"Mike and Clayton did a fabulous job with the installation of our new window film. Mike was so great and patient working with us all the way through this job. In the beginning we had numerous questions re: this film. He answered all our questions and then some and helped us understand the benefits of this film. After the delay with the shutdown, the guys were able to do the installation. Everything went smoothly and we absolutely love our new film. The film we chose cuts 41% of the heat coming into the house and 98% of UV rays that fade the interior floors and furniture. You don't even notice the film is on the window. We will refer Cool View Tint to anyone considering adding film to their windows. They are great."

"I highly recommend Shea for any window tinting project you have in mind. He was able to come out and do my project very quickly (within three days of contacting him). It only took him a little over an hour to do my three windows. What a difference that film had made! My master bedroom has always been unbearably hot in the summer, but it's very cool now. Thanks, Shea!"
