Todays stringent building regulations call for increasing performance of all building products, glass blocks are no exception. We are specialists at sourcing the right glass blocks to achieve the required performance as well as maintaining the desired visual appearance. The three main technical attributes of glass blocks are:
When dealing with fire you must find out the required fire rating. There are two ratings with glass blocks, one is “integrity” ( how long the wall will remain stable when subject to fire on one side) and the second being “insulation” ( how long the wall can resist radiated heat through the wall ). This information is usually provided, or can be found by contacting building control/ local authorities. When the rating is known we can then specify the blocks for you and all the construction detail will be provided where you can build the glass blocks in accordance with the relevant test design detail. Manufacturers have tested their blocks with different details, so we can recommend blocks that will work better for a particular location or design that may be required. If budget is the main concern then we have products at different price ranges, as we said manufactures details differ so there is options.
Glass blocks are also designed to be anti vandal, this is achieved with a thicker wall section to the blocks, in fact double the width. The result is blocks which will withstand heavy attack. Security glass blocks are tested and are provided with ballistics ratings, this gives detail of the impact range that they will resist. Design options are available in terms of pattern, if restricted vision is of importance these blocks can be sand blasted to totally reduce vision. Security blocks are often built into steel frames which when designed correctly gives a very secure window.
Please contact us to discuss any of our technical glass blocks, we are please to assist with all aspects of specification, design and construction detailing.
Our vast knowledge gained from over 15 years experience with all manufacturers of glass blocks means we are very well equipped to advise and guide on all the technical glass block ranges available today. All manufacturers have tested the glass blocks in different ways therefore there are many options; we will propose the most suited products for your project to achieve the required design and visual impact.
All glass block walls must be constructed in accordance with manufacturer’s details. Rayner glass blocks are specialist installers of all fire blocks, insulation blocks and security blocks, offering the complete nationwide supply and installation service. Technical assistance is provided to architects, builders and home owners on all aspects of performance glass blocks.
