Secondary Matting is a type of Entrance Matting that is typically installed internally in Zones 2 and 3. Secondary matting is most effective when used in a three stage Zonal Entrance Matting system.

Having a zonal approach to Entrance Matting will optimise performance to minimise the ingress of soil and moisture into your building. This can be achieved through using either a combination of different products within the range, or by using a consistent product with varying inserts.

The Zonal System

Zone 1. External Matting to remove coarse dirt and grit particles prior to entering the building

Zone 2. Heavy Duty Internal Matting for further dirt and moisture removal.

Zone 3. Close fitted fibre products to thoroughly remove remaining moisture.

As visitors rarely stop to wipe their feet in a commercial environment, sizing is critical – every extra step on the Entrance Matting will further reduce the ingress of soil and moisture.

INTRAsystems recommend that a ‘spill off’ area long enough to accommodate all traffic is installed in Zone 1. Matting should extend at least 1m beyond the entrance doors on either side, and this should be increased depending on the volume and direction of traffic.

The right products for Zones 2 and 3 will depend upon the type and volume of traffic into the building as well as environmental conditions. These zones are the final barrier against the ingress of dirt and moisture, so it is important to specify the correct system.

Zones 2 and 3 will utilise Secondary Matting fibre either in sheet form or as inserts within recessed matting.

Types of Sheet Fibre

There are two types of sheet fibre; Polyamide and Polypropylene.

Polyamide: high quality polyamide sheet fibre is great at absorbing moisture; our products can absorb up to 5.4l/m² moisture – providing exceptional performance even in inclement weather conditions.

As part of our commitment to sustainability, our INTRAlux Elite, Premier, Ulitma and Grafic polyamide fibres are made from 100% Econyl® regenerated nylon and phthalate free backing.

Polypropylene: Provides an effective scraping action due to its abrasive texture. Entrance Matting manufactured from polypropylene such as INTRAlux Rib and INTRAlux Linear are highly durable and excellent at removing dry dirt.

So, how does it all work together and what are the benefits of secondary matting?

Benefits of Secondary Matting

  1. Safety – 90% of slip accidents occur on wet or contaminated floors Effective Entrance Matting significantly reduces the ingress of soil and moisture, and ensures safe access for every visitor
  2. Reduced cleaning and maintenance costs – cleaning costs are estimated to be between £600-£1000 per kg of soil removed. By stopping dirt and moisture at the door you can dramatically reduce costs.
  3. Protect and preserve internal flooring – an average of 0.58g of soil is brought into the building with every entrant. For an office of 500 staff that’s almost 4kg of soil every week causing micro scratches and adversely affecting the aesthetics of floor surfaces. Secondary Matting forms an effective barrier to foot borne soil and moisture, preventing damage to floor coverings.
  4. A great first impression – With reception and public areas visually attractive, safe and clean, your building makes a great first impression on staff and visitors alike.
