Fire Resistant Glass (or Fire Rated Glass) properties
Fire Resistant or Fire Rated Glass is designed to resist and check the spread of fire within buildings. As well as providing a physical barrier, there are also options that insulate the non-fire side against the heat generated by a fire, allowing more time for escape.
The right type of glass can provide an effective barrier to fire within a suitable glazing system. The best of these glasses on the market is the Pilkington range of Pyrostop, Pyrodur, Pyroclear and Pyroshield fire resistant, fire rated or fire protection glass.
This is a range of integrity, denoted by the letter “E” (stays intact despite the effects of fire for a specified period i.e 30, 60, 90, 120 minutes) and insulation, denoted by the letter “I” (reduces the temperature and limits the amount of radiant heat on the non-fire side to manageable levels to allow escape, access for emergency services for a specified period i.e 30, 60, 90, 120 minutes). T A Anders is one of only two independent stockists of the full range of products in the UK.
These products have been developed, refined and improved over 30 years and meet the most stringent demands imposed by test regimes in Europe and across the world.
The products have a body of empirical test evidence, second to none, as well as being part of numerous and extensive assessments conducted by the likes of Exova and published on Certifire.
Pilkington Pyrostop® is a multi-laminate glass product offering a combination of integrity and insulation (EI) from 30 minutes up to 120 minutes (in IGUs). As a single leaf it can offer 30 or 60 minutes integrity and insulation (EI).
Pilkington Pyrodur® and Pyrodur PlusTM is a multi-laminate glass product offering integrity only (E) but also crucially partial insulation (for less than 30 minutes) and radiation reduction (W). 30 or 60 minutes integrity is achieved, depending on which product is used.
Pilkington Pyroclear® is an advanced modified toughened monolithic glass product offering integrity only (E) for 30 or 60 minutes.
Pilkington Pyroshield™ is a monolithic wired glass product offering integrity only (E) for 30 minutes.
All the above are impact safety glasses in accordance with BS 6206 and EN 12600. Further details are available on the attached specification pages for each type of product, including Handling and Usage Guidelines for these products.
As well as supply and deliver, we also offer a glazing installation service for all the above products.
Acoustic Glass properties
Acoustic Glass is designed to reduce the amount of noise passing through the glass. Noise is measured in decibels (dB). All glass blocks a certain amount of noise and generally the thicker the glass, the more noise it blocks. Two leaves of glass in an IGU will reduce noise further and if the leaves are of different thicknesses, further still. This is because sound has a frequency and when it encounters an object it adapts to the frequency required to travel through that object. If it then meets another object that has a different frequency, i.e a leaf of different thickness, it struggles to adapt to the new frequency and some of the sound rebounds off the second leaf. To further enhance this, a special acoustic interlayer can be laminated between two pieces of glass. This interlayer absorbs sound and enables single leaf or IGUs to perform better than ordinary glass.
Here at T A Anders we stock a range of Acoustic Laminated Glass for supply and delivery and also offer a full installation service for these products.
Safety Glass properties
Safety Glass offers various levels of impact resistance in accordance with the classifications within British and European standards BS 6206 and EN 12600 and generally classified by a number and a letter. Numbered 1 – 3 (1 being the most difficult to break) and a letter (A, B, and C) which relates to the mode of breakage. Type A: where numerous cracks appear forming separate fragments with sharp edges, some of which are large, typical of annealed. Type B: where numerous cracks appear, but the fragments hold together and do not separate, typical of laminated. Type C: where disintegration occurs, leading to a large number of small particles that are relatively harmless, typical of toughened.
In terms of impact safety glasses, the three basic types are; Laminated, Toughened and Wired. These can all be obtained on a supply and delivery basis from T A Anders or for installation.
Mirrored Glass Properties
Mirrored or Silvered Glass is float glass, clear or tinted, with a silver and copper reflective coating on the back surface with a painted finish magnetically applied for protection. The use of float glass combined with the method of application of the coating produces a near visually perfect reflection.
Mirrored Glass is available from T A Anders in 4mm and 6mm thickness, with additional processes available, such as, edge polishing and bevelling, drilling holes, sandblasting.
Whether it be for enhanced fire protection, noise reduction, energy efficiency, thermal or solar control or safety, most of the above products can be incorporated into an IGU to achieve the most stringent requirements of the various pieces of legislation and building regulations that govern these areas.
