A poorly insulated building does not really qualify as energy efficient. When conditioned air escapes, it makes it an uncomfortable place to work and live in, not to mention the added cost of heating it during winter and cooling it on summers. There are various Rockwool insulation options in the market that can blend in any structure, climate or space type. The best option for you will depend on the layout of your building.
Cellulose insulation is produced mainly from recycled paper. It is made from the waste materials and energy that is produced in the manufacture of mineral wool insulation and fiberglass. You can reuse scrap cellulose produced as a byproduct during installation to reduce waste. Cellulose insulation does not have any significant impact on the air quality in the building. It is blown into ceiling, wall cavities and attic surfaces.
There are more opportunities to reduce loss of energy with the right insulation on the floors above the ground. Consider your cost, way of insulation, and degree of disruptions to normal activities your facility can bear to narrow down your options. You might need to attach the insulation either to the exterior or the wall for rigid insulations, or make a hole in the wall to spray into the space or the wall of a vacant room such as the attic for flexible materials.
Fiberglass on the other hand, is made of recycled glass and silica sand, which are abundant resources. Its manufacture requires assembling the materials to melt in a fossil fuel, which uses a lot of energy and produces a significant amount of air pollution as compared to other types of insulation. It is hard to inhale the fibers if you install them properly, which can irritate the skin, eye and throat.
Many types of envelops can be easily insulated from the outside in order to reduce interruptions for the occupants. A rigid insulation for exterior applications may come in handy for exterior applications to avoid interfering on the internal space of the occupants residing in the building. If finding the right temperature becomes hard, and you find it either too hot or cold, it could be that the HVAC and insulation systems are inadequate.
Renovating and repairing the roof can be an expensive proposition. As such, unless the lifespan of your roof is coming to an end anyway, you might want to save the project for a later date, and focus first on the rest of the building. Otherwise, some popular options to consider are oriented strand board, rigid planks of foam board, Rockwool blankets and spray foams.
Be sure to check for minimum performance standards from building codes as you select your insulation material and narrow down to your top options to this reference. In order to meet the right standards for fire safety, it may require extra care or an added material such as drywall. Make sure your package has an International Code Council label.
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.
