225mm Cordek Cellcore HX S Under Slab Installation:

The procedure for installing Cellcore panels is straightforward.

Please ensure that Cellcore panels are placed upon a suitable firm and level surface. 

Typically a layer of concrete blinding beneath the panels is recommended.

The lightweight but durable panels can be easily laid by one person. 

Where they are required to be cut this can be carried out using a fine tooth saw or hot wire cutter.

 

Storage and Handling:

All products are delivered in a polythene wrapping and are clearly labelled. 

Both packs of Cellcore and individual panels can be manually handled and offloaded upon delivery, taking in to account any site specific manual handling regulations.

No further storage requirements are needed as the product is unaffected by both UV light and water.

How to understand  the differences between grades?

Grades are specially calculated and calibrated for deformation of EPS under loading.

7/10 grade | 7 means 7 kN/m2 (safe load) | 10 means 10 kN/m2 (failure load)

9/13 grade 9 means 9 kN/m2 (safe load)  | 13 means 13 kN/m2 (failure load)

13/18 grade  | 13 means 13 kN/m2 (safe load)  | 18 means 18 kN/m2 (failure load)

18/24 grade  | 18means 18 kN/m2 (safe load)  | 24 means 24 kN/m2 (failure load)

24/32 grade  | 24 means 24 kN/m2 (safe load)  | 32 means 32 kN/m2 (failure load)

 

What HX S under slab safe load means?

HX S Safe Load simply means safe force that a HX S material offers without fear of breaking - Normal Working Load (NWL)

7 means 7 kN/m2 (safe load) – kilonewtons per m2 

9 means 9 kN/m2 (safe load) – kilonewtons per m2

13 means 13 kN/m2 (safe load) – kilonewtons per m2

18 means 18 kN/m2 (safe load) – kilonewtons per m2

24 means 24 kN/m2 (safe load) – kilonewtons per m2

 

What HX S under slab failure load means?

It means the load at which the under slab will fail (permanent deformation).

10 means 10 kN/m2 (failure load) – kilonewtons per m2

13 means 13 kN/m2 (failure load) – kilonewtons per m2

18 means 18 kN/m2 (failure load) – kilonewtons per m2

24 means 24 kN/m2 (failure load) – kilonewtons per m2

32 means 32 kN/m2 (failure load) – kilonewtons per m2

INSTALLERS

No matter whether you choose a local installer or a national company, there’s a few tips to help you find the right installer for your home insulation improvements, such as asking for recommendations and making sure that they’re part of a certification scheme. This makes sure that they have the right skills and standards of workmanship to carry out the installation, and you can be sure that they know exactly what they are doing.

4 TIPS FOR CHOOSING THE BEST INSULATION INSTALLER

1. Thermal inspection picture in portfolio

It’s worth seeing a installer’s previous work. There’s no harm asking if you can see any properties nearby that they’ve installed insulation in. Best way would be to see Infrared Thermal Imaging Inspections. Thermal cameras spot small, but key changes in temperature in different areas of a house, identifying problematic areas that the human eye never could and some that a visual inspection could only hypothesize.

2. Reviews

Along with checking recommendations and previous work, finding reviews online can often be a great way to find out if they provide a good service or not. However, it’s best not to solely rely on reviews you may find or review websites, as there’s no controlling who writes them.

3. Compare prices

Comparing prices will also ensure companies can’t take advantage of you and give you a fair price. 

4. Word of Mouth

The best way to find a great insulation installer is through recommendations. Make sure you ask friends and family. They will most likely give you their honest opinion and can tell you from first hand experience.

 

Whether you require a wall, cladding, external wall, loft or floor insulation fitted, you can find and hire your local insulation installers from popular UK web pages. A simple internet search will return thousands of potential installers near your area.
