Turning Waste Paper Into
Fiberlite recycles tons of waste paper daily, turning it into an amazing array of cellulose insulation products to improve the energy efficiency and comfort of homes and commercial buildings for the people who occupy them. Let us help you insulate to save money on your utility bills and make your home or workplace more quiet and comfortable.
A common misconception is that all insulations require vapor barriers to protect from moisture. Fiberlite Technologies does not recommend the use of vapor barriers with cellulose insulation except in circumstances of exceptionally high moisture levels, such as for indoor pool rooms or spas. The reason is that
cellulose is the only insulation that actually manages moisture naturally.
Moisture moves in two ways: air movement and diffusion. Of these two, air movement is the more significant accounting for over 98% of the total, and it is the primary cause for moisture related problems outside of floods and leaks. As noted above, cellulose insulation impedes the movement of air. By blocking the movement of moisture-laden air, cellulose insulation reduces moisture movement to manageable levels within a home or building. Any remaining moisture is
diffused within the cellulose insulation, and will be further blocked by primers or paints used on the interior surfaces.
A vapor barrier is not only unnecessary but also can be potentially harmful, especially during the summer months in air-conditioned homes and buildings, when warm, moist air passes through wall assemblies and condenses on the outside of the cool vapor barrier. The hygroscopic nature of cellulose insulation allows it to manage and wick moisture from areas of greater to lesser concentrations, thus preventing damaging amounts of moisture from accumulating.
