Reflective Insulation and Radiant Barriers.
Reflective insulation, is normally made of aluminum foil, it's also known as a radiant barrier and is very Flexible, Light-Weight and easy to Fit.
Everyone has seen reflective insulation without realising it. Paramedics use it as emergency blankets. Firefighters protect themselves from fires with reflective foil insulation. Companies such as NASA use reflective insulation on their shuttles, they protect astronauts with it aswell.
Reflective insulation, mainly blocks radiant heat from transferring through air gaps. Radiant barriers reflect and block excessive heat in the summer and retain heat through winter. Reflective insulation will also reflect the heat generated in your home back inside and block the heat from escaping. Meaning there is less heat escaping keeping your home warmer from less heating for longer. Resulting in lower fuel bills.
Radiant barriers are like all other types of insulation because they lower the amount of heat that enters or exits a home. Other types of insulation trap air inside the insulation, not allowing it to escape and consuming a lot of space. Reflective insulation works to decrease the flow of heat through an airspace using minimal space.
Reflective insulation does not absorb moisture. When used in conjunction with other insulation, it tends to keep the insulation drier and has a better overall performance. It can be used in homes, transportation, factories, greenhouses, summerhouses, barns, conservatories and Many More!
There are several benefits to using reflective insulation. The cost of installation is fairly low and it is easier to install than all other types of insulation. It's CFC & HCFC Free meaning it is made without itchy fibers and can be installed using simple tools like scissors or a Stanley knife, foil tape and a staple gun.
Benefits Of Reflective Insulation
- Light weight, very strong and easy to install
- Moisture-proof - will not allow moisture to pass through in either direction
- Eliminates condensation within the ceiling and walls when properly installed as a vapor barrier
- Unaffected by humidity with lower moisture transfer and absorption rates than mass insulation - no mildew, mold or fungus growth
- No significant mass to absorb and retain heat
- No change thermal performance over time due to compaction, disintegration or moisture absorption - common concerns with mass insulation
- Easier to install than fiberglass - can be stapled, nailed, glued or sewn
- Not a nesting material for rodents, birds or insects
- Non Toxic & Asthma Safe
Radiant barriers are extremely effective in floor systems above cellars and crawl spaces. The reflective insulation may be either stapled below the floor joists, creating a reflective air space, or between the joists creating 2 Reflective air pockets - over and under. Radiant barriers work extremely well insulating floors for two key facts. First, a radiant barrier that is not designed or produced for breathability acts as an excellent vapor barrier. This means that ground moisture and damp won't be able to pass through the radiant barrier and enter your living space. Secondly, the floor is the only place within a room, where the heat flow is always down, different roofs heat would be coming down during the summer and rising to escape in the winter. When the heat flow is down, 93% of the heat is radiant heat, which is exactly what the radiant barrier is designed to block
