What may come as a surprise to many home and building owners is the effect that dirty windows may have on your property’s heat efficiency—but yes, it is true, dirty windows really do. What happens is that when dirt particles collect on your windows, they prevent the entry of ultra violet rays into your property. As this happens, it also prevents the sun from spreading its warmth all over your house, establishment or office during the cold months of the year. Now, if you have low-efficiency windows, then this results to less heat in your space which forces you to turn on your heater to full-blast and thus increase your energy consumptions and consequently, your electric bills. By simply cleaning your windows, you will be able to improve the heat efficiency of your property and save yourself from a lot of unnecessary expenses in the long run.
