My house is seven years old. The original owners built this house as their dream home and left nothing to chance. It is very well insulated. As an afterthought, they built a three season room, using insulated windows, electric heat, etc. however the winters in PA are brutal and the cost of heating that room with a single electric heater is certainly not cost effective. I did purchase a infrared heater to use in conjunction with the forced hot air system in the house and by keeping the doors open, it does make the room comfortable. The AC from the house seems to filter through, making the room enjoyable in the summer.
A long with this issue, I'm on a corner property. Although the traffic is at a minimum I feel like I'm living in a fishbowl at night when the lights are turned on. I hate the thoughts of closing the room up with shades or wood blinds because that's one of the reasons I moved to PA.Ive investigated window film, but although it will address the energy efficiency issue, at night, I'll still be living in a fishbowl on that side of the sunroom. I'd appreciate any suggestions you have.
