Roof Foil Batts

Laid over the top of fibrous bulk insulation they provide extra insulation for walls ceilings and floors.

Roof foil batts.

The idea is that this thin material can act as a type of insulation in tight spaces where you cannot put thick fiberglass insulation. Foil insulation is also known as reflective insulation or referred to as a house s radiant barrier or reflective barrier. In new homes we recommend installing a combination of foil faced roofing blanket and roof batts. Installing foil backed blanket insulation is also a great idea if you are building a flat roof or cathedral ceiling.

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. 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. Keeping homes cooler in summer and warmer in winter. Coupled with good roof space ventilation there can be a significant reduction in heat.

Foil batts stapled between rafters stopping 97 summer radiant heat under 80 100 deg roofs. The r value is a measure of a material s resistance to heat flow known as thermal resistance. It s recommended that you install foil backed insulation in your roof to an r value of r1 0 or higher. If you live in an existing home then consider installing another layer of roof insulation on top of the existing batts.

Ceilings pitched roofs. Roof insulation helps to reduce energy consumption by preventing heat loss during winter and heat gains during summer. 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.

Consertina foil batts are a radiant heat barrier made of consertina style aluminium foil. 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.
