Quality Standards


We achieved ISO9001:2008 certification in early 2010, the standard recognises that the company operates a documented and auditable quality management system.

Every bonded unit is given a unique reference number which enables us to have full traceability. Using this number we can quickly ascertain date of production, material used, priming requirements, glass specification and who glazed, bonded and packed the unit. Each and every unit is subject to a final inspection and sign off before leaving the factory.

At project completion we can collate all of this information into an Operations and Maintenance manual, a copy of which can be sent to the silicone supplier who will issue the warranty.

Investor In People

We have been recognised as an Investor In People company since 2002 and are now approaching our 4th assessment against this standard.

As an IIP company we believe in the development of all staff and in strong communication from management to work force and vice versa.

We have put this in to practice with our modular skills training system which allows every employee to achieve in all areas of production. This has resulted in a highly skilled and flexible work force.

Dow Corning Quality Bond

Structural Glazing Ltd were the first company in the UK to be awarded the Dow Corning Quality Bond standard. This brings additional levels of technical support and warranties for our clients.

We have held the standard since its inception in 2006 and we are audited against it on a yearly basis.

Sika Approved Applicator

We are an approved Sika applicator and can offer Sika-Sil SG500 structural silicone.

All projects undertaken using SG500 are audited and warranted by SIka.

SG Eco Vent – BS & CEN Standards

Our SG Eco Vent was tested by Wintech in March 2009 with the test vent being 1.2m wide by 2.0m high.

The test sequence was to determine the weather tightness of the sample with respect to air permeability, water penetration, and wind resistance. The vent passed both BS and CEN standards at the first attempt. We then retested using 100PA as the test criteria and still passed class 4 in all categories.

The following summarises the results of testing carried out, in accordance with BS 6375 part 1: 2004 and the relevant testing and classification standards.

Test method & Classification Standard Achieved Max. Test Pressure. Classification

Blast Resistance Test

Our SG101/102 and SG Eco Vent were tested for blast resistance in 1997. The system was subjected to explosive pressure generated by the detonation of a 12kg TNT cylindrical charge.

The explosion pressure measurements were as follows;

Peak reflected pressure (on front face) – 383.7 kPa

Average reflected pressure (across face) – 343.9 kPa

Peak reflected impulse (total blast energy) – 547.7 kPa msec

Average reflected impulse (across face of test specimen) – 486.6 kPa msec

Duration of blast load – 6.17 msec

The test results showed that the combination of our frames and DC993 structural sealant performed exceptionally well under the blast loading and no evidence was found of any form of delamination.
