What Is Roof Deck Insulation?

Roof deck insulation is a process by which a home’s roof is insulated in order to protect against the elements. There are two types of roof deck insulation – cold roofs and hot roofs. Cold roofs have insulation between the rafters, allowing for ventilation space below the roof deck.

This type of insulation is important in preventing moisture and condensation, which can lead to rot and mold. Hot roofs are insulated above the rafters.

This type of insulation is important in preventing heat loss and the build-up of ice and snow on the roof. Air sealing hot roofs is critical in preventing leaks and drafts.

Roof deck insulation is commonly found in new construction but can also be added to an existing home. It commonly consists of three components: foam board insulation, vapor barriers, and air barriers.

What Is The R-Value Of Rigid Roof Insulation?

The R-value of rigid roof insulation measures its thermal resistance or ability to resist heat flow. Depending on the application, the higher the R-value, the better the insulation will be at keeping the heat in or out.

Polyisocyanurate is rigid foam insulation commonly used in roofing applications because it has a high R-value of 5.8 per inch.

Rigid foam insulation with a high R-value can help keep your home cool in the summer and warm in the winter by reducing the amount of heat transferred through the roof.

What Type Of Roof Insulation Is Rigid?

Rigid board insulation, which is more typically used to insulate walls in living areas than attics, is produced from polyisocyanurate or polyiso, extruded polystyrene (XPS), or expanded polystyrene (EPS).

This type of roof insulation is very durable and resistant to warping, cracking, or delamination, although it does absorb water. It is manufactured in 4×8 foot sheets or 4×12 foot sheets and comes in various thicknesses.

Rigid insulation effectively reduces heat loss and keeps heat in the attic, helping to reduce energy costs by controlling temperatures within the home.

Rigid insulation has air spaces that control air movement through the attic. This prevents moisture from getting trapped and can prevent damage to the structure of your home.

Does Snow On The Roof Mean Good Insulation?

The snow on your roof is an indication of good insulation. An even covering of snow on the roof means that the insulation inside is working well. It also means that your home receives an extra layer of insulation against cold outside temperatures.

This is due to the fact that snow is an excellent insulator, capable of trapping heat and preventing it from escaping. Thus, a layer of snow on your roof can help keep your home warm, even in winter.
