Rock Wool Insulation Material

By Alex D White


Having a poorly insulated building could have many energy disadvantages. It makes it an uncomfortable place to work and live in if conditioned air escapes. In addition, you will have to incur an added cost of cooling it on summers and heating it during winter. Many Rockwool insulation options exist in the market that can fit any structure, climate or space type.

If you are renovating concrete floors, there are not many options, except perhaps if you are willing to pay for an expensive floor elevation. Insulating walls is quite different. You can add tough foam boards or fiberglass batts to the interior basement walls, although these might require you to install wood studs and drywall.

Cotton insulation, as the name suggests, is made primarily from cotton, with a little boron to prevent fire as well as some polyester. Most of the cotton used in insulation is recycled from scrap generated in the manufacture of denim. The insulation does not have any formaldehyde, and cannot cause skin or respiratory problems from its fibers. You can use cotton batts in the same function as mineral wool batts or fiberglass, rolled out between ceiling joists, open roof rafters or wall studs.

You can easily insulate an attic using loose fill or spray foam if you ventilate it well. Some older roofs though were not set up while considering ventilation, which then limits your insulation options. Spaces that are under high pitched roofs as well as attics that are well ventilated generally remain cooler in summers because of their ability to keep away heat from the ceiling and to insulate the room below.

You can easily insulate many types of envelopes from the outside, and minimize disruptions for the occupants. You might want to use a rigid insulation for exterior applications to avoid interfering on the internal space of the occupants residing in the building. If you find it too hot or cold and getting the right temperature becomes hard, maybe the HVAC and insulation systems are inadequate.

Polyisocyanurate, except in areas that are damp, is the environmentally preferable form of foam insulation. It is made of polysio, a rigid foam board, and covered with a layer of foil at the back as a radiant or vapor barrier, which can be used in almost all areas of your home. Made with more than nine percent of recycled content, and flame retardants, as well as a high R- value, polyiso is preferred as a substitute to polyurethane and polystyrene foam insulation.

It is also important to look for minimum performance standards from building codes as you select your insulation material and narrow down to your top options to this reference. For the right fire safety standards, you might want to apply extra care or an added material such as drywall. Be sure that your package is labeled International Code Council before you select it.

Even for old buildings, you can find an insulating tactic that will guarantee all the needs of the building without excessive costs. Many aging buildings require retrofitting in order to save energy, but many owners do not appreciate the value for this. Just because your building is old does not mean that it has to be torn down.
