Most people nowadays are well aware of the benefits of insulation to keep the heat in, and the cold officially locked out. Preventing the heat from escaping means that you don’t have to use as much energy to keep it warm, helping to keep your costs to a minimum.
There are also environmental benefits of having homes and other properties insulated as it helps to reduce the demand on the nation’s power plants. But can you have too much insulation in your attic?
Insulating is, in no doubt, a good thing! Sometimes, though, there is such thing as too much of a good thing, potentially leading to negatives, right?

Attic Insulation: It Works Both Ways
Don’t forget also that insulation works both ways. Not only does it help to keep the warmth in; it also performs to keep the heat out if needed. This means that in the Summertime, it only helps to make any cooling systems you have work more efficiently.
This helps to ensure that your bills are kept as low as possible during the Summertime, as well as throughout the Winter. Again though, moisture must escape, and too much insulation may prevent this from happening.
Overall though, if you are asking the question of can you have too much insulation in your attic, it’s not really a question of safety. Instead, it’s more a question of necessity and practicality.

Top Tip No.1: Allow Ventilation
As mentioned, while ‘too much’ insulation is not generally a problem, there can be a downside if your insulating material is blocking any vents. It is important to allow ventilation of fresh air in your attic, in order to prevent the build-up of humidity.
Attic vents allow for warm air to be expelled naturally, while replacing it with cooler air from the outside. Sometimes, due care is not taken to ensure that these vents are kept free to circulate air. This can lead to condensation, which in turn, can lead to wood rot, mildew and other moisture related problems.
Most modern homes should already have such ventilation for the attic, although some older homes might need ventilation installed.
Top Tip No.2: Avoid Overkill
One of the reasons to not have ‘too much’ insulation in your attic is to prevent you from spending beyond what is necessary. Added insulation will become decreasingly cost effective the more you add, to the point where it will simply make no difference at all.
This is simply a waste of your money, as well as inviting needless inconvenience. Considering that much of the point of having insulation is to save you money, spending on additional insulation when it is not needed is self-defeating.
If you do have outdated insulation in your attic, however, then adding a modern insulation could help make a considerable difference to your heating bills.
While materials such as fibreglass, mineral wool and cellulose are effective insulation materials, there are more effective materials now on the market.
Having only one product insulating your attic will also make things more convenient when it comes to repairs and maintenance in the future, and its unrivalled longevity also ensures that it will perform effectively long-term!
