Reynaners Bifold Doors Threshold Solutions

A threshold is the sloped cross piece that extends across the bottom of your door area. It slightly raised to keep water from flowing in and often is fitted with a piece of weather stripping to help insulate the area underneath your door.

Reynaers bifold doors come with a choice of four different threshold heights, so your doors can be specified to meet your needs. This means a Reynaers bifolding door can accommodate all types of floor finishes and customer requirements.

The CF 68 is available with four different threshold options:

  • Flush Threshold: 0-15mm,
  • Low Threshold: 9-30mm,
  • Double Weather Seal: 23-44mm,
  • High Performance: 23-74mm.

With these options, you will be able to select the access option that best suits your needs in terms of comfort and ease of access.

Each threshold option gives a trade-off between weather performance and ease of passage.

Standard threshold (Double weather seal)

The standard threshold for Reynaers bifolding doors is a weathered threshold and also the most commonly used in residential buildings. The standard threshold has an upstand (rebate) on one side. This upstand is on the inside on open outwards doors and on the outside on open inwards doors.

The upstand acts as a full weather break stopping any wind or rain in its tracks and guaranteeing that your home remains in top condition regardless of the weather outside. Therefore choosing the standard threshold is the best way of ensuring the optimum weather protection and thermal performance for your doors.

Low threshold

A low threshold provides easy access so it is usually used where accessibility is more important than the weather rating. Since it has lower thermal performance, a bifold door with a low threshold does not offer the same weather performance with standard threshold.

The bottom track can be sunk into the floor so that a flush (level) threshold can be provided between the inside and out. typical uses of low threshold include room dividers, separating a conservatory or commercial applications.

Flush (flat bottom) threshold

A flush threshold, whereby there is a continuous floor with no step between inside and outside, gives the smoothest appearance. However, flush thresholds are not the best at keeping out the wind and rain. The flat bottom solution allows easy passage with no step at all, but this is at the expense of weather-proofing.

 

High performance threshold

The High Performance option offers the best air, wind and water performance but has the highest threshold step.
