Siding R Value

Siding r value.

The higher the r value the greater the insulation performance. In simple terms r values measure the effectiveness of insulation and a higher number represents more effective insulation. R value measures how well certain building insulation materials can resist heat. Structure home insulation system siding is an exclusive combination of vinyl siding technologies and high performance foam that wraps your home in a continuous blanket of insulation keeping you warm in winter and cool in summer.

This means that no matter which material you pick it can serve as additional insulation. Vinyl and lp wood siding have similar r values around 6 with lp siding having the edge. Rosato asbestos insulation is the most authoritative source on asbestos properties and gives data for the thermal conductivity of asbestos in different forms and with varying temperatures for magnesia asbestos insulation at mean temperatures ranging from 100 f to 400 f the k value thermal. Manufacturers often claim a significant reduction in thermal bridging when homes have insulated vinyl siding.

Building materials are given an r value which is a measurement of how well that material resists the conductive flow of heat or how well it insulates. The energy efficiency for building materials is known as r value. R value is a measure of insulation s ability to resist heat traveling through it. The higher the r value the more efficient the building material is.

The table below shows what levels of insulation are cost effective for different climates and locations in the home. For instance if you have a material with an r value of 12 attached to another material with an r value of 3 then both materials combined have an r value of 15. In construction the r value is the measurement of a material s capacity to resist heat flowfrom one side to the other.

Notes to the table above. The higher the r value the better the thermal performance of the insulation. Highly impact resistant and easy to maintain the wide panels look and feel like traditional wood siding. Notes on the r value k values of different forms of asbestos.

The insulation does add some r value to a wall but only a modest amount typically estimated at r 2 to r 2 7. Hardiepanel siding cempanel siding. Jump to specific section. See the brochure.

Most energy experts suggest that your home s walls should have at least an r 13 energy efficiency. The truth is no standard siding material offers very good efficiency. R value see table 2.
