The fantastic UAP Door Stay has now been tested to withstand gale force winds, making it in our opinion the best product on the market!

The restrictor limits door opening to a preset position, or to a maximum of 90 degrees, and includes an easy-to-fit eurogroove and bracket to frame. Our Door Stay is perfectly suitable for all major uPVC profiles, and measures 335mm in length. It can withstand literally thousands upon thousands of openings without becoming damaged, and does not become affected by daily wear and tear! Additionally, a carefully constructed slider contains special friction screws to hold the door open in mild wind conditions, so that it remains stable and steady.

The Door Stay really is in a league of its own as far as door hardware is concerned, and we are ever so proud of what we have achieved. When it comes to furnishing consumers with quality products at reasonable prices, we are a cut above the rest! And the fantastic Door Stay is the perfect example of this!

The UAP Door Stay is very easy to fit and install:

Door Stay fitting 11. Position the UAP Door Stay on to the head of the door sash (105mm from the sash rebate corner on the hinge side.)

Door Stay fitting 2

2. Position the striker plate behind the bead groove on the outer frame 45mm from the corner and screw into position.

Door Stay fitting 3

3. After hanging the sash, clip the arm of the UAP Door Stay into the striker plate.

Note – Should additional friction be required, simply tighten the hexagon screw within the UAP Door Stay.

At UAP we are constantly striving to improve on the products we already supply as well as develop new, pioneering ranges and practical product solutions.

With an in house testing centre and product developer, each stage of the development process is thorough, from the initial design right down to the final product. In house 3D printing technology allows for further and more precise advancement of our products which are then expertly manufactured and put through stringent testing conditions using in house test equipment – ensuring all products are designed to the highest standards: 

Salt Spray Test

This machine tests the corrosion resistance of the door stay. The salt spray cabinet produces a corrosive environment, by releasing a dense saline fog into the chamber which the door stays are exposed to. This creates an accelerated corrosion of the door stay and allows us to test how well the door stay would stand up in harsher environments. The door stays are tested for 480 hours.

Door Stay Strength Test Report Data:

The door stays were mounted on representative sections of PVCu door profile. These were then installed on a test fixture such that loads could be applied representative of those seen in service. The Door Stays were installed in accordance with the UAP fitting instructions. The loading position was at 375mm from the hinge edge of the dummy door. This would be the centre line of a typical 750mm wide door. The initial tests were to determine the load to overcome the detent holding the door open when the load was applied in the closing direction. The first series of tests were carried out with the fiction slider set in the loose position as supplied. A second series of tests was then carried out with the slide tightened such that a 10N operating load (on door centreline) was required. The stays were then tested with the load in the opening direction. In this instance the load was increased to destruction.

In all cases the Door Stay operated without damage.

Analysis

A typical door will have an area of 1.5m².

Using this value: To close the door with a tightened slider and a closing load of 31.3N would require a wind pressure of 20.9Pa

To force open the door with a failure load of 524N would require a wind pressure of 349Pa.

The actual wind pressure for a door can be calculated by the methods in BS 6375 using location, orography and the building design. This can vary widely throughout the UK.

BS 6375 gives two main classifications for doors: 800 and 1200. These are:

Exposure
Category
Maximum Test
Pressure (Air
Permeability)
Maximum Test
Pressure (Weather
tightness)
 P1   P2   P3 
800 300 Pa 100 Pa  800 Pa  400 Pa  1200 Pa
1200 300 Pa 100 Pa  1200 Pa  600 Pa  1800 Pa

The first two test pressures are those used to record the doors air and rain leakage. So these are the figures which will often be encountered in use. P2 is used for a repeated pressure test again at a pressure level often encountered. The pressure P1 is used to measure the deflection of the door in high winds such that sealed units and similar are not damaged. Pressure P3 is based on the peak wind pressure that would occur once every 50 years and requires the door to be safe at this pressure. Given that the door is unlikely to be left open during periods of high winds, the pressure P2 is likely to be the worst that the Door Stay would encounter in general use.

It can be seen that the Door Stay would not prevent the door from closing in the worst conditions utilised in these test pressures. However, doors are not likely to be left open in extreme conditions. Also, should the slider be set correctly, the door will close gently rather than slam shut.

To force open the door and break the stay would typically take around 350Pa. It can be seen from BS 6375 this would equate to a wind speed of around 19.3m/s. Whilst, the Door Stay would fail at a high wind speed it is unlikely that a door would be left open in those conditions.

Summary

When applying a closing force to the Door Stay, the stay would yield with a typical pressure of 20Pa. In this instance, the Door Stay is not damaged.

When applying an opening force to the Door Stay, the stay fails at a typical pressure of 350Pa. This equates to a wind speed of around 19m/s (42.5 miles per hour).
