270mm Cordek EPS Void Former Cellvent HX Grade 13/18 is used beneath reinforced concrete floor slabs to provide a combined ground heave protection and passive gas venting system.
Cordek EPS Void Former Formwork Cellvent HX 270x1200x2400mm is designed for use under suitably reinforced ground floor slabs where subsidence is not expected.
Cellvent HX is supplied with an equivalent ventilation capacity to the Ventform 80 range which includes a 40mm void depth, If a greater venting capacity is required, please contact us.
The depth of the Cellvent HX panel will depend upon the amount of ground heave that has been predicted.
Grade 13/18 is calculated and calibrated for concrete thickness up to 460mm (has been tested to achieve the specified performance characteristics).
Cellvent HX is a highly-durable, BBA certified product which meets the NHBC’s Technical Standards.
One of great things about Cordek Cellvent HX is its very simple to work with and doesn't have much dust off when cut on site.
The cost of manufacturing Cellvent HX is considered linearly proportional to its grade which is based on maximum concrete depth.
270mm Cellvent HX Grade 7/10 price is the lowest compared to the higher grades: 9/13, 13/18, 18/24 (price list available upon request/quote).
Equivalent to 270mm Cordek Cellvent HX is 225mm Cordek Cellcore HX S Under Slab.
Grade 13/18 means that safe load is 13kN/m2 and fail load is 18kN/m2 (kilonewtons per m2).
Safe load is a maximum safe force that a Cellvent HX material offers without fear of breaking.
Fail load is not safe force and will cause permanent deformation of the product.
Shrinkage category of 270mm Cellvent HX is classified as high.
270mm Cordek Cellvent HX Soil Plasticity index is 40-60.

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.
