The key areas of energy loss at home is the attic. More than 35% of hot air in winter and cool air in summer is lost through the attic, which is one reason why they are so tightly insulated from most of the time. Insulation must be adjusted to change the loft room in a performance, so make sure you wrap the main contractor in the field of new meeting space with insulation. Attic ventilation must be installed, because they tend to get quite a bit of heat and stuffier than at home, even during winter (heat rises, so does the attic a few degrees above The rest of the house when the heat is working properly).
