Upgrade your Aga Cooker Insulation

This 4 Oven 13amp Aga Range Cooker, recently benefitted from our Insulation Upgrade. A complete overhaul of the subpar insulation, with our own specific insulating process for more efficient use and cheaper bills!


When this 13amp 4 Oven Aga Range Cooker was first installed, it was insulated using a mix of vermiculite (the stuff that looks like popcorn), and rockwool (the blankets of loft insulation you see) on top.


The problem is that over time, vermiculite can drop as it settles into crevices and rockwool can deteriorate. When this happens, you can end up with big air pockets in the cooker that you're paying to heat, and it doesn't retain the heat for long. Even if your vermiculite hasn't dropped, modern advancements mean that we have much better insulation available to us to increase the efficiency of your Aga Range Cooker.

Once the old rockwool  is removed, our big industrial hoover gets to work - sucking the loose vermiculite out of the Aga Range Cooker. Our insulation process is carried out, then a thick blanket is installed on the top to tuck your cook in, nice and snug! The top plate is put back on and you're good to go!


The majority of other refurbishing companies advertise a repack/insulation upgrade service, which consists of additional vermiculite and a new top blanket. Our process is a complete overhaul. Our repack service and process is specific to us - other companies and engineers will have a different processes they will follow when preforming a repack.


Any ceramic blanket we use is safe and body soluble. We've been very thorough in our research, making sure we don't use the popular (carcinogenic!) aluminium fibre version, which is much cheaper to produce.


We have our own supplier of 100% bio-soluble insulating blanket, which has been proven to disintegrate when it comes in contact with lung membranes - perfect for any dust particles that make it past our masks!


If you decide to enlist the help of another company for your repack, PLEASE make sure you're confident in their knowledge and ability; your health is not worth the risk.
