Can I put a blanket on the windows to keep the heat in?

• <div><p>Hanging a thick blanket over your windows will help to keep the heat inside, but only a little. Covering the glass will also prevent the sunlight from getting in, which might actually decrease the efficiency of your window overall. If you get to the point where you’re hanging blankets over your window to keep warm, call in an expert to seal around your windows to prevent warm air from escaping. They may also recommend replacing old windows that aren’t as insulative as newer window technology. Sealing a window isn’t terribly expensive and can make a big difference.</p></div>

Q: Where should I not use spray foam insulation?

• <div><p>You should not use spray foam insulation in several specific areas. Avoid applying it in spaces exposed to high temperatures, such as near electrical boxes or recessed lighting, unless the foam is specifically rated for such use. Applying foam near electrical boxes can damage the wiring, and using it too close to lightboxes or recessed lights creates a potential fire hazard. Additionally, do not use spray foam in areas prone to shifting or movement, as this can lead to cracks and gaps in the insulation. Finally, open-cell foam is unsuitable for use below ground or in areas exposed to moisture because it can absorb water, which compromises its insulating effectiveness.</p></div>

Q: What is best to put on windows to keep cold out?

• <div><p>To keep cold out, look for treatments that sit close to the window frame and are made from thick, insulating materials. Thermal curtains, cellular shades, window quilts, and insulated shutters can all help retain heat. Layering window treatments, like pairing lined curtains with cellular shades, can provide even better insulation by further reducing drafts and heat transfer.</p></div>

Q: Should all interior and exterior walls be insulated?

• <div><p>While insulation is required for all exterior walls in a house, it is not typically required for interior walls. Local and state building codes mandate that new construction homes have adequate insulation in exterior walls and ceilings to suit the local climate.</p><p>However, there are several benefits to adding insulation to interior walls.

"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."
