Maintain a comfortable temperature balance in your home with proper insulation in the attic, floors, and walls. Fiberglass prevents energy loss and reduces the work the HVAC system needs to do, while stone wool acts as a fire retardant and provides soundproofing. Protect your home's foundation with impermeable membranes that block the entry of water. Reno also offers other types of building insulation, such as foam panels and bubble foil. Keep the humidity out by installing a vapour barrier in any outward facing walls and in ceilings.
