The average cost to insulate an attic is between $1 and $7 per square foot. This equates to a typical price range of up to $1,500 per project including labor and materials. For attics with smaller square footage, costs can be as low as $500 while insulation for larger attics can cost up to $4,000.

Is it worth insulating your loft?
Insulating your loft, attic or flat roof is an effective way to reduce heat loss and reduce your heating bills. Installed correctly, loft insulation should pay for itself many times over in its 40-year lifetime.
How long does it take to insulate a loft?
It takes up to 2 hours to install Loft Insulation in an average three-bedroom house. Larger homes and bungalows may take a little longer as they have a bigger loft space.
Can you put too much insulation in loft?
As long as you ventilate your property properly, you can have as much insulation as you like within reason. The trick with loft insulation is to balance the amount of insulation you have with the amount of ventilation necessary to prevent damp. As long as you get that balance right, you should be fine.
Should you remove old loft insulation?
In most circumstances removing your old insulation isn’t necessary and it can actually be quite beneficial to leave it. This is as most insulation will retain its thermal properties so leaving it in place will mean that you continue to benefit from it whilst also having an additional layer of insulation on top!
Should loft insulation go to the edges?
Insulation should be continued right to the edge of the ceilings but it shouldn’t block the eaves’ ventilation. You must also avoid laying insulation over recessed light fittings or cables in the loft space that may overheat.
Is it better to insulate attic ceiling or floor?
roof insulation is no-contest. The floor wins every time. Insulating the floor is standard practice for an unfinished attic space. The exception to this rule takes place when families opt to convert an unfinished attic space into something usable or livable.
Does loft insulation cause damp?
Loft insulation itself will not ’cause’ damp issues as such – as in it will not act as the main catalyst for it. However, if a poor insulation material is chosen, and an ineffective method undertaken, then this certainly won’t help matters.
How much of a difference does loft insulation make?
The most obvious difference offered by an insulated loft is the saving in energy bills, and it’s very simple here. It’s estimated that a quarter of all the escaping heat from a building goes through the roof. If that could be stopped, your bills should be reduced by a quarter.
How much insulation should I have in my attic?
R-Value is a measure of insulation’s ability to resist heat flow. The higher the R-Value, the better the thermal performance of the insulation. The recommended level for most attics is to insulate to R-38 or about 10 to 14 inches, depending on insulation type.
How do I know how much insulation I need?
Measure the height and width of any windows or doors in the wall. Multiply the measurements to find the area of each window or door, and subtract them from the total square footage of the wall. This gives you the square footage of insulation you need for that wall.
How often should you change loft insulation?
Loft insulation is effective for at least 40 years and it should pay for itself many times over. The material may have become damaged with wear and tear, or simply degraded with time if it was laid some years ago.
Why do Lofts get so dusty?
1. From outside your apartment. Dust from outdoors gets into your apartment through doors, windows, and cracks in your apartment walls. Pollen, soil particles, particulate matter from smoke, and other unwanted particles find their way and contribute to the accumulation of dust in your apartment.
Is it safe to touch loft insulation?
The nature of the insulation means its fibres can come loose and stick to your skin, and to your nose, mouth and eyes. So it doesn’t cause cancer, but it can cause irritation to the skin, nose, eyes and lungs if you touch it, or if you are exposed to it at close range for long periods of time.
