Featuring a number of impressive designs and numerous finishes the Secured by Design Door Viewers range at UAP Ltd will look fantastic on any composite or timber doors!

Recently Secured by Design have updated the specification for door viewers, and in order to reach SBD specifications a door viewer must have a viewing angle of at least 120 degrees from the end of the viewer (i.e. 60 degrees at both sides):

120 degree test

Door viewers  (spyholes) are a great security accessory for your customers, as no door should be opened without first checking who is on the other side. Door security is essential to ensuring a home is safe and once quality locks have been fitted it’s key to have a door viewer. Many homeowners overlook the importance of really seeing who is on the other side of the door and essentially this can actually be the best way to prevent unwanted guests, break-ins, and scams. Providing your customers with this important information will help them learn to better protect their homes and keep intruders out.

Each spyhole has gone through rigorous testing, and have each been tested to DHF TS002:2009 which covers Corrosion Resistance, Security (Angle of Vision), Visual Clarity, Resistance to Misting Up, Ability to Clear After Misting, Length Adjustment Range and Marking. The door viewers have also been awarded 'Secured by Design' by the Association of Chief Police Officers.

With a variety of Secured by Design door viewers homeowners will be able to select the viewer most suitable for their needs and overall home interior and exterior. Whatever their overall door hardware finish is there is a spyhole suitable to match it. In addition in our Door Viewers range we also offer several fantastic door knockers which have a hole specifically designed to fit a door viewer.

Be sure to also check out our door knockers range for more fantastic options which can also have a door viewer fitted. Made with a solid brass body, and comprising of 3 plastic lenses, each spyhole ensures to give crystal clear performance for years of safe, secure use.

PVD Gold, Mirror Polished and Satin Stainless are part of the UAP Nanocoast range.  These products are made from 316 grade stainless steel, and are specifically designed for areas which are within a 25 mile radius of the coast, or within 5 miles of highly populated industrial areas. Unlike brass and zinc based products, the Nanocoast products will not pit, rust or corrode no matter what environments you put them in. This means that the products will last longer, and keep your customers happy. What’s more, every Nanocoast product comes with a lifetime coating guarantee!

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 viewers. The salt spray cabinet produces a corrosive environment, by releasing a dense saline fog into the chamber which the products are exposed to. This creates an accelerated corrosion of the product and allows us to test how well the door viewer would stand up in harsher environments.

The door viewers are tested for differing lengths of time depending on the standard requirements; 480 hours for brass, zamak and aluminium based door viewers where we offer a 5 year inland coating guarantee, and in the case of stainless steel Nanocoast door viewers, we test for 2,000 hours where we offer a LIFETIME coating guarantee anywhere in the country, as the door viewers will not pit or rust.

All Weather Machine

When placed in the all-weather machine, the door viewers are subjected to conditions including high UV exposure using a Xenon Arc Lamp which will accelerate UV degradation and measure how well a door viewer can last in extreme conditions.

Other conditions such as rain and extreme heat can be generated by the machine to expose door viewers to all kinds of environments. This allows us to continually improve the door viewers and make them so they last longer in all kinds of different environments.

DHF TS 002:2009 Test Report Data:

Corrosion Resistance
Door Viewer was subjected to a neutral salt spray test as detailed in BS EN 1670:2007 for 96 hours (grade 3).

Comments Grade
Minor red corrosion of cover 3

Angle of Vision

The door viewer was mounted, in accordance with the manufacturer’s instructions, to a 45mm thick (+/-1mm) wooden block which, in turn, was mounted perpendicular to a protractor. Whilst looking through the door viewer, a point source of light was moved into view and the angle at which it first appeared (measured from a datum perpendicular to the “door” face) was noted. The test was repeated from the 180° opposite position and the two readings were added together to give an average “viewing angle” for the cone of vision.

Visual Clarity

The door viewer was mounted in a suitable test-rig in which the viewer was held perpendicular to a sheet of text at a distance of 150 mm. Using normal or corrected normal vision, in good light, attempts were made to read text in progressively smaller point sizes and the smallest point size that could be read was noted. (The font used was Arial Black – regular, printed using Microsoft Word).

Resistance to Misting Up

The door viewer was mounted, in accordance with the manufacturer’s instructions, to a 45mm thick (+/-1mm) painted wooden block – representing part of a typical external door to a dwelling. This, in turn, was mounted in a test-rig in which the viewer was held perpendicular to a sheet of text at a distance of 150 mm. Using normal or corrected normal vision, in good light, attempts were then made to read text in progressively reducing font sizes and the smallest point size that could be read was noted. The wooden block was then stood upright in an environmental chamber and subjected to 72 hours of cyclic humidity to BS 3900-F2:1973. Immediately after the humidity test, the readability test was repeated by the same person.

Ability to Clear After Misting Up

Following the humidity test, the door viewer (still in the wooden block) was allowed to dry out for 72 hours at 30° C, after which the readability test was repeated by the same person who carried out the initial test.

Length Adjustment Range

The door viewer was screwed up to its shortest length and the distance between the mounting flanges noted. It was then unscrewed so that there was a full turn of engagement on all threaded connections and the distance between mounting flanges was again noted.
