The Right Insulation increases building energy efficiency, improves health and well-being and reduces greenhouse gas emissions.
Total R-Values are based on the sum of all components of the building system including indoor and outdoor air-films, building materials used in the system and air-spaces.
• Bulk insulation thermal resistance is expressed by Material R-Value
• Reflective insulation thermal resistance is expressed in terms of System R-Value
Single Sided Poly Weave Foils
A polymesh woven material with a reflective foil adhered to one side; polymesh products can also have a paper inner core layer, the other side typical being opaque. Sometimes referred to as radiant barrier insulation. Polymesh products are also available in breather (moisture vapour permeable grades. (Emissivity of bright face assumed to be 0.03, poly weave face is 0.87).
Double Sided Anti-glare Foil
Antiglare foils with reflective foil on each side of an inner paper based lining, one face being coated with an antiglare ink to reduce glare. Also available in breather grades and in perforated form where holes are approximately 2mm in diameter resulting in 10% open area. (Emissivity of bright face assumed to be 0.03, antiglare face is 0.1)
Double Sided Foam Foils
Double-sided reflective foils. One side coated with antiglare to reduce glare. Centre core material, typically 7mm thick enclosing a single layer of individual air bubbles or closed cell foam (Emissivity of bright face assumed to be 0.03, antiglare face is 0.10)
Ceiling and Wall Batts
Lightweight, flexible and resilient bulk glass wool Insulation batt, specially designed for thermal Insulation of ceilings and cavity walls in both domestic and commercial buildings. They have the added benefit of being an effective sound absorber and so contribute to both the thermal and acoustic Comfort of building occupants.
Foil Faced Blanket
Roofing 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.
(Emissivity of bright face assumed to be 0.03).
Antiglare Reflective EPS Board
Foil-faced polystyrene foam boards consist of expanded polystyrene rigid sheets (EPS) faced
on both sides with a reflective foil laminate, one face additionally coated with an antiglare ink to reduce glare. (Emissivity of bright face assumed to be 0.03, antiglare face is 0.10).
