Pre-Engineered Metal Building Insulation is a highly efficient, lightweight, strong, resilient, and easy to handle flexible blanket insulation composed of line, stable and uniformly textured inorganic glass fibers bonded together by a non-water soluble and fire-retardant thermosetting and heat resistant resin. It is free from coarse fibers and shot due to its mineral composition.
Pre-Engineered Metal Building Insulation is designed and factory-laminated to a choice of functional finishes to provide attractive interiors, abuse resistance, and assistance in the control of moisture or vapor condensation. Pre-Engineered Metal Building Insulation is available with one side factory applied Aluminium Foil Glass Reinforced Kraft Paper Laminate (FRK), White Metalized Scrim Kraft (WMSK) or other specific vapor barrier facings. The use of the proper facing helps to preserve the inherent fire safety of metal buildings. These facings brighten the building interiors due to their high light reflectance, reduce the cost of interior lighting, contribute to an effective vapor barrier and to the control of condensation and dripping moisture.
A 50 mm (2 inch) stapling and taping overlap flange on one side or both sides of these facings is available. The facings are also available with UL fire resistant rating.

AFICO Pre-Engineered Metal Building Insulation is manufactured specifically for use in the roof and side walls of commercial, industrial, residential, agricultural and poultry farms metal building construction. This insulation greatly reduces heat gain or loss through the building envelope. It will not rot, disintegrate or slump.
Several methods are used to insulate metal buildings. The usual method is to apply the insulation over the structural members (purlins and girts) and inside the exterior panels.
This method generally accommodates single layer insulation to R-13. Methods are also used to apply insulation in metal building roofs between purlins so as to accommodate greater insulation thickness and better thermal performance.
In some cases, two insulation layers are necessary or desirable. In such case, Pre-Engineered Metal Building Insulation provides an economical unfaced second layer. The table below shows how double layer application may be used to achieve desired R-values.
|Desired R-Value||First layer (Faced)||Second Layer (Unfaced)|
|16||R = 7||R = 9|
|19||R = 7||R = 12|
|25||R = 7||R = 18|
|31||R = 7||R = 24|
