Preguntas y respuestas: Cómo afecta la orientación del hogar al aislamiento continuo

Hay mucho que considerar cuando se trata de construir una casa energéticamente eficiente para sus clientes y los muchos matices que cambian con cada construcción, incluida su orientación al sol. Nos sentamos con Neil Freidberg, gerente de Ciencias de la Construcción en LP, para analizar el impacto de la orientación del hogar en las necesidades de aislamiento continuo.

Q: What is the relationship between the orientation of a structure, its walls and continuous insulation?

A: You insulate differently based on the direction a wall faces and how the sun hits-and heats-your structure. Take a home that is built with each wall facing exactly north, south, east and west, for example. The east, south and west sides of the building are going to see a lot of heat gain from the sun whereas the north side will see less, potentially needing a different amount of insulation than the sun-facing sides to keep the internal temperature balanced throughout.

Q: Do I need more or less insulation for north-facing walls?

A: Ultimately, it depends on your climate. In places with high heat such as desert climates, the goal is usually to keep heat out, so you'll need more insulation on the sun-facing walls. However, in the north, where it is much cooler, your goals will likely shift to keeping heat in, so your north-facing wall may need more insulation than the others.

Q: What materials can help regulate temperature?

 A: LP NovaCore® Thermal Insulated Sheathing is a great base for the initial thermal bridging. Made with Owens Corning® FOAMULAR® NGX™ XPS foam, it provides continuous insulation at an R-3, R-5, or R-7.5 value per inch without the long-term R-value deterioration associated with other foam insulation products.

Q: Can you use LP NovaCore sheathing on its own?

A: If R-3, R-5 or R-7.5- is the right continuous insulation R-value needed for your walls, you may be able to use LP NovaCore sheathing on its own. However, since different wall orientations often have different insulation needs, one wall may use just LP NovaCore panels while another may need the panels as a base and additional insulation with it.

Q: What other factors may play a role in continuous insulation? 

A: Most homes are not perfectly oriented with walls facing exactly north, east, south and west, so taking the entire environment into consideration is crucial. Is it on a hill? In a valley? How do the trees impact the amount of sun a structure gets? What about the neighboring homes or buildings? The same goes for the architecture of the house. For example, if your client has a great view toward the north that they want their home to face, it will require windows on the side of the house that is already the coldest. With that in mind, you'll want to use more insulation on this wall to balance out the internal temperature, and so on.

When approaching a new build, remember to consider the climate and orientation of the house to most efficiently insulate the structure.
