Examples of where to insulate. 1. In unfinished attic spaces, insulate between and over the floor joists to seal off living spaces below. Attic access door. In finished attic rooms with or without dormer, insulate between the studs of "knee" walls, between the studs and rafters of exterior walls and roof, and  How To Get Rid Of Mold In A Crawlspace ceilings with cold spaces above. 

Extend insulation into joist space to reduce air flows. 3. All exterior walls, including walls between living spaces and unheated garages, shed roofs, or storage areas; foundation walls above ground level; foundation walls in heated basements, full wall either interior or exterior. How To Get Rid Of Mold In A Crawlspace  Floors above cold spaces, such as vented crawl spaces and unheated garages. 

Also insulate (4A) any portion of the floor in a room that is cantilevered beyond the exterior wall below; (4B) slab floors built directly on the ground; (4C) as an alternative to floor insulation, foundation walls of unvented crawl spaces. How To Get Rid Of Mold In A Crawlspace  Extend insulation into joist space to reduce air flows. 5.

Insulating your home saves money and improves comfort. Insulation choices depend on your climate and how your home is constructed. 

HOW DOES IT WORK? Insulation provides a protective barrier between the conditioned areas of your home and the outside environment. How To Get Rid Of Mold In A Crawlspace For optimal energy efficiency, your home should be properly insulated from the roof down to its foundation. In addition to insulation, consider moisture and air leakage control in each area of your house. 

If radon is an issue where you live, How To Get Rid Of Mold In A Crawlspace you'll also need to consider radon-resistant construction techniques as you research foundation insulation options. In addition, if you live in an area with termites, you'll have to consider how termite protection will affect the choice and placement of insulation in your home. 

ATTIC INSULATION Loose-fill or batt insulation is typically installed in an attic. How To Get Rid Of Mold In A Crawlspace Loose-fill insulation is usually less expensive to install than batt insulation, and provides better coverage when installed properly. See more on different types of insulation. Before insulating, seal any air leaks and make roof and other necessary repairs. 

If it is located in a conditioned part of the house, also remember to insulate and air seal your attic access. Insulate and air seal any knee walls -- vertical walls with attic space directly behind them -- in your home as well. How To Get Rid Of Mold In A Crawlspace In addition, if you're building a new home or remodeling, make sure any attic decking that provides additional storage space.

A platform for a heating and/or cooling unit or hot water tank is raised above the ceiling joists to leave room for adequate insulation. Finally, if you live in a hot or warm climate, consider installing a radiant  barrier in your attic to reduce summer heat gain. DUCT INSULATION. How To Get Rid Of Mold In A Crawlspace If the ducts in your home are in unconditioned space, seal and insulate them. 

If you're building a new house, place ducts in the conditioned space to avoid the energy losses associated with most duct systems. CATHEDRAL CEILING INSULATION. How To Get Rid Of Mold In A Crawlspace Properly insulating your cathedral ceilings will allow ceiling temperatures to  remain closer to room temperatures, providing an even temperature distribution throughout the house. 

Cathedral ceilings must provide space between the roof deck and  home's ceiling for adequate insulation and ventilation. How To Get Rid Of Mold In A Crawlspace This can be achieved through the use of truss joists, scissor truss framing, or sufficiently large rafters. For example, cathedral ceilings built with 2x12 rafters have  space for standard 10-inch batts (R-30) and ventilation. 

Foil-faced batt insulation is often used in cathedral ceilings because it provides the permeability rating often required for use in  ceilings without attics. A vent baffle should be installed between the insulation and the roof decking to maintain the ventilation channel. How To Get Rid Of Mold In A Crawlspace Consider using high-density R-30 batts,  which are as thick as R-25 batts, but fit into 2x10 framing. 

You can also add rigid foam insulation under the rafters, which adds R-value and eliminates thermal  bridging through wood rafters. However, rigid foam insulation must be covered with a fire-rated material  when used on the interior of a building. How To Get Rid Of Mold In A Crawlspace Half-inch drywall is usually sufficient, but check with local building officials before installing. 

EXTERIOR WALL INSULATION In an existing home, consider using loose-fill or sprayed foam insulation, which can be added to exterior walls without much disturbance to finished  areas of your home. How To Get Rid Of Mold In A Crawlspace If you're remodeling and your wall cavities will be open, look into blanket (batt and roll) insulation  options, especially if you'll be doing the work yourself. 

In a new home, first see our information about insulating a new home, which will help you choose from among the many types of  insulation on the market. How To Get Rid Of Mold In A Crawlspace If you're in the design phase of planning your new home, consider structural insulated panels, insulating concrete forms, and insulated concrete blocks. 

These materials literally  have insulation built in, and houses built using these products often have superior insulating qualities and minimal thermal bridging. How To Get Rid Of Mold In A Crawlspace If you're building a traditional framed house, consider  using advanced wall framing techniques. 

These techniques improve the whole-wall R-value by reducing thermal bridging and maximizing the insulated wall area. How To Get Rid Of Mold In A Crawlspace Also  consider using insulating wall sheathing rather than wood sheathing products. Half-inch foam sheathing provides an R-value of R-2 to R-3.5 and thicker foam board yields even higher R-values. 

Foam sheathing: Provides a continuous layer of insulation, which reduces thermal bridging through wood studs, saving energy and improving comfort. Is easier to cut and install than heavier sheathing products. How To Get Rid Of Mold In A Crawlspace Protects  against condensation on the inside wall by keeping the interior of the wall warmer. Usually costs less than plywood or  oriented strand board (OSB). 

If you replace plywood or OSB with foam sheathing, your walls will  require bracing or other structural reinforcement. INSULATING FLOORS ABOVE UNHEATED GARAGES. How To Get Rid Of Mold In A Crawlspace When insulating  floors above unconditioned garages, first seal all possible sources of air leakage. 

This strategy has the  added benefit of minimizing the danger of contaminants (from car exhaust, paint, solvents, gardening  supplies, etc.) in the garage migrating into the conditioned space. How To Get Rid Of Mold In A Crawlspace Also install an air barrier to prevent cold air in the garage from "short circuiting" the insulation underneath the subfloor.
