High Density Insulation R Value

High density polyisocyanurate foam core.

High density insulation r value.

Control and sound absorption in floors and walls. High density batts for a 2 by 6 inch 51 by 152 mm frame wall offer r 21 and high density batts for an 8 5 inch 216 mm spaces yield about an r 30 value. R 38 ecobatt kraft faced high density fiberglass insulation batt 10 1 4 in. It provides r values that range from 3 6 to 4 2 per inch.

It delivers a higher r value per square inch in less space than standard insulation products. Aging effects comments. Insulation or other building material 9. In the context of building and construction the r value is a measure of how well a two dimensional barrier such as a layer of insulation a window or a complete wall or ceiling resists the conductive flow of heat.

Products with a higher r value have a higher cost but have an increased capacity to resist heat flow and therefore provide greater insulation. 15 bags for ceilings and attics easy to cut and install with low dust provides temp. Also called styrofoam insulation this is the least expensive material. The ultra r r 50 insulating panel is a rigid polypropylene encased vacuum insulation panel that is custom made to the client s specified dimensions.

Polyisocyanurate polyurethane foam insulation r values. The r value for foamular xps insulation is provided from testing at two mean temperatures 40ºf and 75ºf and from two aging conditioning techniques 180 day realtime aged as mandated by astm c578 and a method of accelerated aging sometimes called long term thermal resistance lttr per can ulc s770 03. Each type comes with unique advantages. Polyurethane spray closed cell foam insulation.

High density cathedral ceiling batts allow an airspace between the insulation and roof deck for ventilation. Thanks to thanks to andrew cole for correcting our data on this product. These batts meet the energy saving requirements of today s codes without requiring changes in construction. R value is the temperature difference per unit of heat flux needed to sustain one unit of heat flux between the warmer surface and colder surface of a barrier under steady state.

High density means more fi bers per square inch. Owens corning r 21 ecotouch insulation is specifi cally engineered to solve the effi ciency problems of exterior 2x6 walls. R 21 ecotouch insulation is available in batts unfaced and. A medium density batt offers r 13 for the same space.

High density sidewall batts are available in sizes to fit standard construction without loss of r value due to compression.
