Easiest polystyrene to install in rafters
Diy_44 - 1 year ago
Bought loads of this stuff and also tried the polystyrene sheets. This is by far the easiest to install. The cut grooves make is so much quicker and if your loft is like mine (random beam gaps) it's much easier to install as it can be contracted and expands to fill gaps. It's messy to cut though!

Handy sized panels; fairly easy to cut to size using a hot wire cutter for polystyrene. Designed to snap on ziz-zag sections which generates a small amount of polystyrene debris, and these weren't where I needed to split. Need to measure carefully to get enough panel width to spring out to hold the panel in the rafter gap. Too little and it may drop out, too much and it curves out with a belly.
I found the best way to give the 5cm (2") gap was to use netting staples as pins in the rafters.
Meets the need for variable rafter gaps - good idea to read the instructions available online first.
Cheaper than a competitor.
Only problem is that you need a lot of these to do a full roof, and it's not currently possible to order directly from website to be delivered directly, and click an collect is dependent on them being in stock at your chosen branch.

I bought the product to insulate my loft rafters they worked very well. However I exhausted the stocks of both my local stores and still require 12 more packs but stocks have not been replenished for nearly two weeks. My project has ground to a halt unfortunately. Please can someone sort out the stock levels so I can complete my project.
