Standard Plastic Circles for Concrete Reinforcement are specially designed to provide a consistent 30mm cover for reinforcement bars ranging from 12mm to 20mm in diameter.

Manufactured from durable copolymer polypropylene, these spacers ensure precise rebar positioning within concrete structures, enhancing both durability and compliance with building standards.

Ideal for vertical and horizontal reinforcement applications in slabs and foundations, they are suitable for high-load conditions and offer excellent stability in both precast and in-situ concrete projects.

Their UV-resistant composition makes them highly suitable for outdoor or exposed environments.

These heavy-duty spacers are robust, easy to install, and help maintain bar alignment during concrete pours, ensuring structural integrity in foundations, walls, and floors.

Designed to securely hold rebar in place while preserving consistent spacing, they promote free concrete flow and help prevent weak points caused by uneven cover.

Particularly effective in column and wall casting, they support precise vertical alignment where accuracy is critical.

Together, this range of Standard Plastic Circles offers a comprehensive solution for achieving accurate and reliable rebar cover across a variety of concrete construction scenarios.

We can help to calculate price per m2 or linear meter (one meter in length) cost, please just contact us via phone 02081910776, email or live chat. 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.
