external envelope Providing a facade experience with a different perspective
Traditionally, glass is used to create a barrier to protect its encased environment. However, selecting the wrong glass can affect the overall visual performance by resulting in unwanted glare and reflection, while at the same time reducing light transmission and overall aesthetics. Guardian Clarity™ is the right glass that can make the difference. Standard glazing units reflect light at a level that may interfere with our ability to see through the glass easily and clearly. For some applications, any interference is too much interference. Now there is a solution. Guardian Industries’ Glass Group in Europe, a leading manufacturer of high performance glass and a key supplier to the building industry, has introduced Guardian Clarity anti-reflective glass. Created by using the most advanced coating technology, Guardian Clarity is ideal for glazing applications in which excessive glare and reflection create an obstruction and outstanding transparency is desired. Guardian Clarity anti-reflective glass helps facades achieve more light and less reflection, delivering eye-popping optical properties for premium facade experiences, or any application in which a stunning view is an advantage. Used in combination with other Guardian® glass products, it can help in meeting local regulations in terms of energy performances through thermal insulation and/or solar control. Clarity is offered as standard on Guardian UltraClear™ low-iron glass, leaving a crystal-clear and light-weight appearance.
enq.193 Specifying rooflights to meet the requirements of Part Q
Recent changes to Building Regulations Approved Document Q: Security in Dwellings means that anyone wishing to install rooflights in ‘easily accessible areas’ will need to ensure that they specify a product which is compliant with Part Q. The document explains ‘easily accessible’ as “A window or doorway, any part of which is within 2m vertically of an accessible level surface such as ground or basement level, or an access balcony, or A window within 2m vertically of a flat or sloping roof (with a pitch of less than 30 degrees) that is within 3.5m of ground level”. These changes are most likely to affect domestic dwellings with flat roof single storey extensions featuring rooflights that fall within the criteria, although each project should be dealt with on a case-by-case basis. Glazing Vision’s Secure and Secure+ rooflights have been tested to the latest LPS 2081:1 2015 standard, which is designed to replicate a typical stealth attack commonly carried out in residential areas. The range is accredited by the Loss Prevention Certification Board issued by the BRE. Secure and Secure+ rooflights are the first in the UK to be backed by the official police security initiative Secured by Design to LPS2081:1 2015. Rooflights designated with the ‘Secure’ rating have been tested to LPS2081 security rating A.
