Specifically for south facing conservatories where the polycarbonate roof is staying in place with white outer material facing the sun. Fitted in place of normal foil insulation that has a foil outer which will heat up very quickly in direct sunshine and possibly damage the insulation and polycarbonate sheeting, I used this after a conversation with YBS directly.
Noticed the difference straight away - have gained another room. Keeps heat out in summer and heat in during winter.
The Toolstation description says it’s 25m long, it’s not, it’s 10m long.
The YBS packaging says 10m.
Easy to cut using scissors.
