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. Iā€™m delighted with the quality of materials and service and I will reorder from Trade Insulations Ltd at the next stage of my renovation.

75mm Celotex Cavity Wall Board Application

Celotex Cavity Wall Boards are designed for use in partial fill, masonry cavity wall applications. The product itself is specifically made to fit between cavity wall ties. 75mm Celotex Cavity Wall boards are 75mm in thickness. Cutting the board is not required as it fits standard wall tie spacing requirements. This cuts down installation times and therefore makes it a great solution to traditional methods.

75mm Celotex Cavity Wall Insulation Boards are tongue and grooved and are lightweight and easy to install.

The Celotex CW4000 range is long-lasting and extremely durable. When storing 75mm Celotex Cavity Wall Insulation, we recommend that you store the PIR board inside. Furthermore, this is to prevent the effects of weathering. If there is no other option but to store the cavity wall boards outside then keep them raised from the ground to avoid ground moisture. The 75mm Celotex Cavity Boards should be kept out of direct sunlight. If outside, this means they should be either under cover or protected with opaque polythene sheets. Furthermore, adverse weather effects could damage the board and affect performance so correct storage is appropriate. It is also worth noting that all of our CW4075 Cavity Wall boards are brand new. As a dedicated seller of insulation, we are able to offer our best price on 75mm Celotex Cavity Wall Insulation.
