Can I install loft insulation myself?
If your loft is easy to access and has no damp or condensation problems, it should be easy to insulate – and in many cases, it is possible to do it yourself. If access is easy and your loft joists are regular, you can use rolls of mineral wool insulation.
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.
Can you lay loft insulation over joists?
Loft insulation is a barrier of material within your roof space. It can either be laid between the joists (the horizontal beams along the floor of your attic) or the rafters (the angled beams that support the roof).
Can I lay loft boards over insulation?
Placing loft boarding over insulation is an easy process and is essential if you want both storage and for your quilt insulation to work at its optimum performance. With the correct products, such as Loft Legs, this is easy and cost effective too.
Can I insulate the underside of my roof?
Open-cell spray polyurethane foam or closed-cell spray polyurethane foam (ccSPF) insulation can be sprayed along the underside of the roof sheathing to provide a conditioned and insulated attic space that can be durable and efficient in all climate zones (see Figure 1).
How many layers of loft insulation do I need?
Measure the loft hatch and cut insulation to size. You will probably need two layers to achieve the recommended depth.
Can I insulate my loft with Celotex?
Using rigid insulation board as loft insulation Some people may prefer to use rigid insulation board to insulate the loft space – for example Celotex or Kingspan – the process is pretty similar to above, although you will need less depth to achieve the same insulation levels (than mineral wool).
How thick should my loft insulation be?
Current government recommendations are for loft insulation to achieve a depth of between 250mm and 270mm but some new properties are increasing their level of loft insulation to 300mm. Again, as long as the loft has adequate ventilation, this is fine.
Can Celotex be used for loft insulation?
Should roof rafters be insulated?
Insulating between rafters will do no good, because the attic should be ventilated, and the rafter insulation would be between two unheated spaces. You can add insulation to the floor; the more the merrier. Moisture buildup in the attic is a concern because it can condense into water, often causing mold.
How deep should I insulate my loft?
To reach the recommended loft insulation depth of between 270-300mm, a second layer can be added. Simply unwrap the insulation and lay at 90-degrees to the first layer and ceiling joists.
How do you insulate between floor joists?
Gently push the insulation so it fits snuggly between the joists, but don’t compress it as that will reduce its efficiency. When you reach a cross beam, use a straight edge or metal ruler and a snap off knife to cut the insulation to fit. To join two lengths of insulation, simply butt them up tightly.
How do you remove insulation from a loft floor?
Lift all electric cables above the insulation and cut away around visible light fittings. All wiring in the loft must be lifted and laid on top of the insulation otherwise the cables will overheat and become a fire hazard Cut the roll in the centre of the floor when rolling out from the eaves on both sides.
How do you lay electrical wiring in a loft?
Lay both layers at right angles to eachother Lift all electric cables above the insulation and cut away around visible light fittings. All wiring in the loft must be lifted and laid on top of the insulation otherwise the cables will overheat and become a fire hazard
