    en.wikipedia.org/wiki/List_of_insulation_materials

    This is a list of insulation materials used around the world. Typical R-values are given for various materials and structures as approximations based on the average of available figures and are sorted by lowest value. R-value at 1 m gives R-values normalised to a 1 metre (3 ft 3 in) thickness and sorts by median value of the range.

    Cellulose insulation is environmentally preferable (80% recycled newspaper) and safe. It has a high recycled content and less risk to the installer than fiberglass (loose fill or batts). [27] R-Value 3.4 – 3.8 (RSI-0.60 – 0.67) per inch (imperial units) Loose fill insulation fills the wall cavity better than batts.

    en.wikipedia.org/wiki/Closed-cell_PVC_foamboard

    PVC foamboard is distinct from the extra-lightweight foamcore board, laminated of foam and card surfaces, used for indoor signage and modelling. Like PVC, closed-cell PVC foamboard is solid and has a very rigid structure. Where it differs is in its closed-cell foam structure, which makes it very light (as little as half the weight of solid PVC ...

  8. Polyvinyl chloride - Wikipedia

    en.wikipedia.org/wiki/Polyvinyl_chloride

    Polyvinyl chloride is formed in flat sheets in a variety of thicknesses and colors. As flat sheets, PVC is often expanded to create voids in the interior of the material, providing additional thickness without additional weight and minimal extra cost (see closed-cell PVC foamboard). Sheets are cut using saws and rotary cutting equipment.

  9. Structural insulated panel - Wikipedia

    The third component in SIPs is the spline or connector piece between SIPs. Dimensional lumber is commonly used but creates thermal bridging and lowers insulation values. To maintain higher insulation values through the spline, manufacturers use Insulated Lumber, Composite Splines, Mechanical Locks, Overlapping OSB Panels, or other creative methods.
