The misery of lifting and relaying roll insulation continues.

There is a small section that is above a dorma window. It isnít very large but not easy to access. Cutting boards and then crawling along with them seems over rated. Any ideas on where I could get one bag of loose fill insulation to pour in. I could drag it along behind me and pour it down the gap. I am based in Cambridgeshire.

Ventilation isnít really a problem because the bottom is blocked so there is no airflow anyway. The rest of the loft has really good airflow.

I canít see any in a mainstream shop and I donít fancy traveling miles for it. Thanks

Thanks I looked at perlite for the loft. I will see if they will sell me a single bag if I visit.

Do you know anyone mainstream that sells it. £13 a bag plus £15 delivery unless I get two bags then it went up to £45 delivery.

I have used both in reasonable volumes for differing applications. The micafil is by far the easier and faster to handle. It also pours and flows well and produces little to no dust. In comparison the cellulose needs to be broken up and aerated before being blown or poured in, You can do this quite simply with a plastic dustbin or similar, a 240v drill for torque and a plaster mixing paddle on the drill BUT it means  lots of dust in the air and time consuming. Cellulose was great for blowing into totally inaccessible area at a distance with a garden vac but not a quick/simple solution.

If you can see the site you wish to insulate go with the micafil even if you have to jug pour it in.

Just one guys view though.

Travis Perkins was my stockist for micafil, ask for a discount at the desk.
