R value – 1.3This 55mm insulation blanket provides excellent thermal insulation properties, keeping homes and buildings cooler in summer and warmer in winter. When installing- the foil should face down into the roof space, and the blanket should face up against the under side of the roofing sheets. Useful Links: 1. General: R-Value of Various Materials: Here’s a handy R-value table that covers most types of roof coverings, building insulation, and a few other materials. You should, of course, see the manufacturer-provided technical data sheet for the R-value of specific products. 2. General: For a very good introductory overview article on R-value, see "R-Values" over at the website of. As you survey the different types of insulation, you will see this R-value change based on various factors: the composition, density, and quality of materials.

Think Green Insulation is a polyester Roof Insulation. Ideally used as a top up. OrUnfortunately, this insulation type does not meet the standards to achieve the recommended R-value requirements for the major regions. Think Green Insulation is more an economy type Roof Insulation. The maximum thermal performance or R-value of insulation is very dependent on proper installation.. Construction workers fit SIPs together to form walls and roof of a house.. Blanket: Batt and Roll Insulation.

Earthwool roofing blanket provide a cost-effective thermal and acoustical barrier for energy-efficient construction. The consistent quality, low dust, and clean-cutting resilient fibres makes for fast and easy installation. Knauf Insulation Earthwool Foil Roof Insulation can be used in new and retrofit applications in commercial and residential structures, as well as in off or on-site. What does insulation R-value mean? An insulation product’s resistance to heat flow is measured by its thermal and acoustic resistance or R-value. The higher the R-value, the more effective that product will be at keeping your home cooler in Summer and warmer in Winter. Insulation R-value depends on a number of factors including thickness. 1. Calculate percent improvement in R-Value: R3 + R18 = R21 total Roof R-Value. I calculate insulation resistance to heat loss or "R" percentage improvement always as relative to the original number. The increase = R21 – R3 = exactly 18 – the value by which you are increasing the R-value.

Our skillion roof blanket insulation is available in a 570mm wide fold to fit rafters at 600mm centres. Folds are supplied in 2.6m lengths and range from 3-6 folds per bale. Skillion ceiling cavities can have a higher risk of condensation occurring (Branz Bulletin 610). Where insulation is required to achieve its full R value it must not be laid over the purlins. Insulation must be laid between packers fixed onto the top of steel purlins with a 25mm air gap between roof and insulation. If this is not followed and the insulation is fixed over the top of the purlins and squashed down, the R value will be reduced. The reflective foil faced insulation blankets are ideal for the metal roof insulation process because of the large range in blanket R-value. Additionally, this blanket insulation is cost-effective, odourless, low dust, non-combustible and no added formaldehyde, which make easy to handle and install.

Roof Insulation Metal roof insulation is the best way to control condensation, temperature and reduce unwanted noise. Roofing insulation/blanket consists of a lightweight flexible bulk mineral insulation blanket faced on one side with reflective foil laminate. The blanket material is available in various R-values and thicknesses. R-value means the thermal resistance (m2 K/W) of a material. R-value measures how well certain building insulation materials can resist heat. The higher the R-value, the greater the insulation performance. When determining how much insulation you need, don't guesstimate, calculate. Know exactly how much you need with our project calculators.
