Roof Foil Batts

The r value is a measure of a material s resistance to heat flow known as thermal resistance.

Roof foil batts.

Most commonly it s supplied as sheets used for sarking laminated onto plasterboard or expanded polystyrene xps or supplied as a backing on concertina style batts or multi celled i e. Found in major outlets such as in home depot s insulation aisle reflectix comes in tightly spooled rolls of 25 by 2 feet of shiny reflective foil look bubble wrap texture insulation in plastic bags. Consertina foil batts are a radiant heat barrier made of consertina style aluminium foil. Foil insulation is insulation that has a thin layer of reflective foil on one or both sides and is designed to reflect heat.

Dust on upper foil surface is of little importance downward air spaces constantly emit re radiate only 3. Foil batts stapled between rafters stopping 97 summer radiant heat under 80 100 deg roofs. Coupled with good roof space ventilation there can be a significant reduction in heat. Installing foil backed blanket insulation is also a great idea if you are building a flat roof or cathedral ceiling.

Laid over the top of fibrous bulk insulation they provide extra insulation for walls ceilings and floors. If you live in an existing home then consider installing another layer of roof insulation on top of the existing batts. Roof insulation helps to reduce energy consumption by preventing heat loss during winter and heat gains during summer. In new homes we recommend installing a combination of foil faced roofing blanket and roof batts.

Keeping homes cooler in summer and warmer in winter. Foil insulation is also known as reflective insulation or referred to as a house s radiant barrier or reflective barrier. Radiantguard radiant barrier foil insulation installed in an attics can reduce attic temperatures by up to 30 degrees when stapled with a staple gun to the underside of roof rafters by reflecting up to 97 of the radiant heat that strikes its surface thereby reducing heat transfer from the attic to living spaces resulting in lower utility bills.
