Glass Wool Insulation R Value

R value denotes resistance to heat flow. Essentially the higher the r value the more effective the insulation is. Sheep wool insulation r value equals or often surpasses that of other insulation materials.

Glass wool insulation r value.

The thermal resistance or r value of polystyrene foam board depends on its density. 25 50mm aslo r p tissue and rigid boards etc glass wool insulation is one of the most widely used forms of insulations world wide because of its thermal and acoustic properties light weight high tensile strength and exceptional resilience. Fiberglass offers an r value of 2 2 to 2 7 per inch while rock wool has an r value of 3 0 to 3 3 per inch making it a slightly better insulator than fiberglass according to the u s. When comparing the two glass wool has a slightly lower r value of around 2 2 2 7 compared with 3 0 3 3 of mineral wool which means it is slightly less effective at preventing heat loss through conduction.

Manufactured from glasswool the batts are specially stiffened and treated to provide a moisture resistant insulation meeting the building code of australia s minimum requirements for energy. For example if you have a type of insulation that has an r value of r 5 per inch of thickness you will need a depth of 6 inches of this insulation installed in your attic to reach r 30 if you live in zones 2 or 3. R value figure is usualy provided by the manufacturer of a particular insulation product and is shown in the product description.

Bradford gold wall batts are available in r values from r1 5 r2 0. Fiberglas insulation foamglas cellular glass foamular xps thermafiber mineral wool. The r value is a measure of the insulation batt s resistance to heat flow also known as thermal resistance. High compressive portfolio uses thermacrimp technology to make the highest compressive strength mineral wool ci on the market.

The greater the r value the greater the resistance to heat transfer and the greater the insulating effect and subsequent energy savings. These r values are a sum meaning this should be the total r value once you add up the entire depth of insulation. The r values of each product are 3 6 per inch and 4 3 per inch respectively. The higher an insulation s r value the greater its insulating power.

R value is used to measure materials ability to resist heat or in other words resistance of a material unit to heat transfer. R value figure can be calculated from the equation. Over time the r value of xps insulation can drop as some of the low conductivity gas escapes and air replaces it a phenomenon is known as thermal drift or ageing. Polystyrene loose fill or bead insulation typically has a lower r value compared to the foam board.
