We Carry All Types Of Insulation Panels and Rolls

Robert N. Karpp offers a full line of insulation panels, batts and rolls for your commercial and residential building needs. We carry products for both interior and exterior applications from major manufacturers like Knauf, CertainTeed and Rockwool. Our insulation solutions include:

  • Batt/roll insulation – made from fiberglass, mineral wool, plastic fibers or natural fibers. Batt/roll insulation is used on unfinished walls, foundation walls, floors and ceilings.
  • Loose-fill and blown-in insulation – made from cellulose, fiberglass or mineral wool. Loose-fill insulation is most useful for hard-to-reach places, enclosed existing walls, open wall cavities and unfinished attic floors.
  • Rigid fiber insulation – made from fiberglass or mineral wool. Rigid fiber is often used in locations that are subject to high temperatures, such as ducts.
  • Rigid foam board insulation – made from polystyrene, polyisocyanurate and polyurethane. Rigid foam board insulation must be covered with ½ inch of other materials (like gypsum board) or with weatherproof facing.
  • Mineral wool insulation – this special type of batt insulation is made from stone wool and is naturally fire retardant. It also reduces unwanted noise transfer between rooms, does not deteriorate, can be installed at any temperature, and is resistant to water, mold and mildew.

Our professionals are standing by to help you find the correct solution and R-value for your particular construction application. So if you’re looking for insulation, look no further than Sun Valley Supply.
