Loft hatch

Great hatch. Feedback on why 4 stars: Supplied fibreglass should be in a sealed bag, because you brush past the fibres going up and down. A wider range of sizes would have been good as we had to reduced the loft opening to suit, but cant really mark down the specific product for that. Fitting around an existing ladder is a two person job. Seem to have a decent enough seal, so hopefully will help reduce condensation in the loft.
Comment from Jupiter Blue: Thank you for your comments. This is a fire rated product, the only materials suitable to make a cover for the mineral wool insulation which will also pass the fire test are incredibly expensive and would add a huge premium to the product.
