Properly insulated exterior walls in your house will not only increase comfort but also help you save on heating and cooling costs. For energy savings, you can add insulation to your walls in an existing house. If you're building a new house, you have many energy-efficient wall insulation options to consider.
Topic Summary
Before insulating your walls, you should ensure that they're properlyair sealed。Moisture controlis another consideration.

You'll find manytypes of insulationfor walls. However, for adding insulation to existing finished walls, you might first consider using松散填充要么sprayed foam insulation。可没有太多干扰到你家的成品领域添加这两种类型的绝缘层。

如果你还没有准备好，先请参阅有关信息insulating a new home。This will help you choose from among the manytypes of insulationfor your walls, including some construction techniques.
Unlike traditional stick-frame houses, houses constructed usingstructural insulated panels,隔热混凝土模板, andconcrete block insulation从字面上内置到他们的墙壁保温。因此，这些房屋通常具有优异的绝热性能和水平。
If you'd prefer to build a stick-frame house, you should consider using advanced wall framing techniques. These techniques improve the whole-wallR-valueby reducing thermal bridging and maximizing the wall area that is insulated.
For stick-frame house construction, you also should consider using foam-insulated wall sheathings instead of the standard wood or asphalt-impregnated sheathing. A half-inch thick foam-insulated sheathing provides an R-value of R-2 to R-3.5. Sheathing thicker than a half-inch thick will yield even higher R-values.These are some other advantages of foam sheathing:
- The continuous layer of insulation reduces thermal bridging through wood studs, saving energy and improving comfort.
- 泡沫护套是更容易切割和安装比较重的覆板产品。
- 它通过保持壁回暖的内部防止在内壁凝结。
- It usually costs less than plywood or oriented strand board (OSB).
