What is 1555mm Cellcore HX B ?

155mm HX B Under Beam is a lightweight enhanced EPS (expanded polystyrene) block designed for use beneath reinforced concrete ground beams and pile caps to protect against the potential effects of ground heave. 

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 B under beam safe load means?

HX B Safe Load simply means safe force that a HX B 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 B under beam 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

Is it complicated is to work with 155mm HX B Under Beam?

NO, is not. One of great things about 155mm HX B Under Beam is its very simple to work with and doesn't have much dust off when cut on site.

What is the 155mm HX B Under Beam shrinkage category?

Shrinkage category of 155mm HX B is classified as MEDIUM.

What is 155mm HX B Under beam plasticity index?

155mm HX B Under beam Plasticity index is 20-40.

What is the maximum depth of concrete dedicated for 155mm HX B Under beam?

Grades are specially calculated to withstand the load of concrete as per below: 

7/10 - from 0mm up to 220mm concrete thickness

9/13 - from 220mm up to 300mm concrete thickness

13/18 - from 300mm up to 460mm concrete thickness

18/24 - from 460mm up to 660mm concrete thickness

24/32 - from 660mm up to 900mm concrete thickness

Why knowing Cellcore grades is so important?

Each grade has adequate strength to support a specified depth of wet concrete during construction and will collapse under its specified fail-load, limiting the upward presssures experienced periods od clay heave.

How to install 155mm HX B Under Beam?

The procedure for installing Cellcore panels is straightforward. Cellcore panels should be placed upon a suitable firm and level surface.

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

Panels can be easily laid by one person.

How do cut 155mm HX B Under beam?

Cut can be carried out using a fine tooth saw or hot wire cutter.

How can I joint Cellcore HX B boards?

Individual panels should be butted together, with taping of the joints using the formwork tape to avoid any grout loss between the panels.

Formwork sealing tape, typically 50mm wide is used to seal the joints between adjacent panels. Tape should be used to tape the joints to stop the ingress of concrete slurry weeping down between the panels and cousing a dead spot.

Is Cellcore 155mm HX B Under Beam BBA Certified?

Yes, 155mm HX B Under Beam has BBA Certificate.

Do I need Damp Proof Membrane for Cellcore HX B?

Yes, damp proof membrane should be used either on top or underneath the screed.

Can I walk on 155mm HX B Under Beam ?

No, 155mm HX B is made of moulded collection cellular legs with only 5mm twin fluted polypropylene top which is not strong enough to actually walk on during placement of base spaces and reinforcement.

How to recognize grades on HX B boards?

It is very easy. Each grade has own color code.

They are labeled to easily find on site which grade goes in which area.

7/10 grade is colored  RED 

9/13 grade is colored BROWN 

13/18 grade is colored YELLOW 

18/24 grade is colored BLACK 

24/32 grade is colored BLUE 

The cost of manufacturing Cellcore HX B is considered linearly proportional to its grade. 155mm Cellcore HX B 7/10 price is the lowest compared to the other grades: 

7/10 grade 

9/13 grade 

13/18 grade 

18/24 grade 

24/32 grade

Alternatively, you can work it out yourself quickly and easily: to get cost per meter square please divide price shown in orange area by ''Required area (m2)'' Example price of £28.80 divided by board coverage 2.88m2 = cost of £10.00 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.
