20mm Aluminium Vented Base Track SF is a high quality resistant to corrosion and weather conditions ventilated profile designed for External Wall Insulation (EWI) systems and thin coat rendering.

Ventilated Base Track 20mm is used in insulated render systems as a cover for the lower part of the 20mm thick thermal insulation boards (Expanded Polystyrene Grey and White (EPS), Kingspan K5 or Mineral Wool) against mechanical damage and pests.

This bottom bead is a 2500mm long profile made from 0.65mm thick raw aluminium to meet the recommendations of insulated render systems manufacturers.

Building Regulations demand different air flow rates within the cavity of Steel Frame structures.

Vented Base Tracks have been introduced to overcome this issue with the addition of slots at the rear of the profile sections at different centres to deliver the different airflow rates that are required.

Ventilation rate per 2500mm length is 382.85mm2 and 153.141mm2 per 1000mm.

Vented Base Rail is made of a self-hardening aluminium alloy with magnesium and silicon additives.

It is distinguished by its excellent durability and high corrosion resistance.

Easy to handle and install Ventilated Starter Beads are available in: 20mm, 25mm, 30mm, 40mm, 50mm, 60mm, 70mm, 80mm, 90mm, 100mm, 110mm, 120mm, 130mm, 140mm, 150mm, 160mm, 170mm, 180mm, 190mm, 200mm, 210mm, 220mm, 230mm, 240mm and 250mm widths.


Vented Base Track (Steel Frame) Installation:

 · Before starting the external wall insulation works, the height of the plinth should be determined and it should be marked with a horizontal line.

 · The bottom bead should be installed at a height of approximately 300-400mm from the ground level.

 · Starter track is fastened to the base with a expansion plug, using at least 10 fixings per 2500mm length.

 · The batten should always be fastened in the first and last holes.

 · Level the unevenness of the walls with the spacers.

 · The end of the vented profiles at the wall corners, where two profiles connect, should be cut at an angle of 45 degrees.

 · The base track must be installed perfectly horizontally to facilitate the correct installation of the thermal insulation boards.

 · Any deviation from the horizontal will result in gaps between the insulation boards.


Key points:

 · Doesn't rust.

 · Easily machined and cast.

 · Lightweight yet durable.

 · Recyclable material.

 · Non-magnetic.

 · Non-sparking.

 · Good heat conductor.

 · High quality.

 · Easy to install.

 · Can have an indefinite life.

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.


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.
