Initial impressions : i was dubious of ordering after seeing some of the negative reviews, but equally amused by trade insulation replies....... i was looking at reviews because i'd never heard of the business, but after reading the reviews it became clear that actually the place was not a scam, the goods were arriving however people had not paid attention to tickboxes at checkout or were expecting craned deliveries (again not reading checkout\terms) and leaving their mrs at home to accept the orders i ordered 50mm celotex, and rwa45 insulation it's all arrived on the day they said it would yes i needed to help unload it, but guess what, i ordered it to use it so i fully intended to be handling it anyway and not only that even if i didn't need to help i would have had to move it anyway as they would have just done a kerbside delivery driver was great, he asked if i was comfortable in lifting the pallet of pir off in one go, (if you're not you're an adult, simply say no and open the pack) basically it came from travis perkins and i imagine it will come via other major suppliers too much like most of the online companies..... but because these guys order such large quantities they can pass on the discount and they're responsible for dealing with the the like of the tp if there's an issue summary : Yes i would recommend and yes i will order again

My materials were delivered within the specified delivery window. The delivery guy was very skilled at navigating our driveway and he dropped the materials right at our front door. I’m delighted with the quality of materials and service and I will reorder from Trade Insulations Ltd at the next stage of my renovation.

Question:

Is 50mm sound insulation enough?

tradein

Answer:

A recommended minimum thickness of 50mm should be applied in stud wall applications. If you can go thicker, the additional thickness of the insulation will offer better levels of sound insulation. Please note doubling up on thicknesses will not result in twice the level of soundproofing.
