What is the best form of loft insulation?
The most common form of loft insulation, this comes in rolls of rock, glass or mineral fibre (we use Earthwool by Knauf which is a really good environmentally friendly option), or else foil-backed felt. It’s generally the cheapest option and good all-purpose insulation, especially for between joists.
What type of insulation is the most cost effective?
Expanded polystyrene (EPS) is a premier material for protecting homes, foods and sensitive materials because of its cost-effective, efficient insulation qualities. In fact, EPS leads the pack when it comes to R-value per dollar.
Which type of roof insulation is best?
One of the most common and effective ways to insulate your roof is with polyurethane spray foam. This spray-applied plastic is known to be highly effective for sealing any cracks as well as resisting wind and heat. The foam is applied to the underside of your roof deck and directly onto the slates and tiles.
What is wrong with Fibreglass loft insulation?
Fibreglass Insulation: The Disadvantages If laid in the loft, it should be covered by boards and not touched. If it becomes wet, it loses its insulation qualities, making it ineffective. This can happen if the product becomes directly wet (ie if there is a leak in the roof), or if it is affected by condensation.
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.
What is the cheapest attic insulation?
Attic Insulation Blown-In vs Batt Batts are most commonly added to the space between joists in floors and walls, and blown-in is most commonly added to the attic floor. Of the two, batts are generally the least expensive method and easiest to DIY.
What type of insulation is best for attic?
Fiberglass, cotton, and mineral wool can all work as loose-fill material, but the far and away top choice for blown-in insulation is fiberglass. Contrary to batts, blown-in fiberglass insulation is perfect for filling in tight voids around wiring, pipes, or any area with awkward framing.
What is the most efficient ceiling insulation?
Spray foam insulation
Spray foam insulation is a new and incredibly effective insulation solution. Spray foam insulation is applied by spraying a solution in the ceiling, floor or walls which bubbles into a thick layer of insulation. It generally has a higher R-value than traditional forms of insulation.
Does Fibreglass loft insulation deteriorate over time?
The simple answer is ‘yes’. Insulation is not designed to last forever, eventually it will begin to degrade and whilst you may not always be able to see the deterioration, you’ll certainly notice it.
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.
Where do you put insulation in a loft?

Another disadvantage is that you have more space to heat as you are heating the whole loft space, as well as all the habitable rooms, however typically the insulation performs better so will generally offset this disadvantage.
How much heat is lost in an uninsulated loft?
A quarter of heat is lost through the roof in an uninsulated home. 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.
