Difference Between Roof And Ceiling Insulation

The table below shows what levels of insulation are cost effective for different climates and locations in the home.

Difference between roof and ceiling insulation. Unfinished walls ceilings floors and roofs for new construction. Later on we will discuss the differences between a cathedral ceiling and a vaulted ceiling. These tiny pieces of insulation do a great job at insulating because they spread evenly throughout the space wrapping around any obstacles like the outlets wires pipes and ductwork. Residential insulation is designed for the four main areas of your home.

Find your zone on the map and then use the chart to determine the level of insulation you need to properly insulate your attic walls floors and crawlspaces. A cathedral ceiling requires some degree of roof insulation. Roof vs ceiling. Ceiling walls underfloor and between floor areas.

Greater than 80mm insulation requires the use of spacers to ensure the integrity of the insulation is kept and not compressed between the roof sheets and the roof frame. Insulation is designed specifically for each area to ensure it fits the required stud spacing s cavity depth and thermal ratings r values. Achieving greater r values in attics the higher the r value the better the thermal performance of the insulation. The type of insulation you need depends on which type is currently installed and the required r value.

Insulation types include loose fill batts rolls foam board spray board and vapor barriers. However the two terms refer to two entities as distinct as a nut and a bolt and there is no reason to fail to distinguish between the two. R value is a measure of insulation s ability to resist heat traveling through it. A vaulted ceiling does not necessarily require roof insulation because there is an air cavity separating the interior of the home or conditioned space from the roofline.

Construction workers fit sips together to form walls and roof of a house. The higher the r value the better the thermal performance of the insulation. Thicker insulation is more commonly used in commercial applications. May 13 2011 posted by olivia.

The most common insulation materials are fiberglass cellulose and foam. When choosing which thickness of insulation residential roofs will choose either the 60mm or 80mm thickness. Good for adding insulation to existing finished areas irregularly shaped areas and around obstructions. This can be achieved through the use of truss joists scissor truss framing or sufficiently large rafters.

Insulation level are specified by r value. For example cathedral ceilings built with 2x12 rafters have space for standard 10 inch batts r 30 and ventilation. Structural insulated panels sips foam board or liquid foam insulation core. The main benefit to using blown in insulation is how perfectly and completely it fills the space in between the walls floors and ceilings of your home.
