1 Introduction

This document constitutes a scope of application report relating to the following Norsound Ltd glazing systems for 30 and 60 minute fire resisting doorsets:

1. Norsound Vision 30B & 30T

2. Norsound Vision 60B & 60T

3. Norsound Vision 60B Slimline

Note: Unless otherwise explicitly excepted, any reference to Norsound Vision 30B or 60B applies equally to Norsound Vision 30T or 60T as appropriate.

The report will summarise the scope of application of the above Norsound Vision glazing systems when used to glaze timber based fire resisting doorset assemblies and will be based on the associated test and assessment data.

The report uses established extrapolation and interpretation techniques in order to extend the scope of application by determining the limits for each of the glazing systems, based on the tested constructions shown in appendix A and the performances obtained. The report is an evaluation of the potential fire resistance performance, if the element/s were to be tested in accordance with BS 476: Part 22: 1987.

2 General Description of Norsound Glazing Systems

The essential elements of the Norsound glazing systems referenced within this assessment comprise of intumescent materials contained within a PVC casing, which is fixed into position between the faces of the glass and the retaining beads – either with adhesive tape or in the case of the Norsound Vision 30T by means of a co-moulded plug (which does not contain intumescent material) which locates into a groove machined in the face of the bead as illustrated.

3.2 Timber based fire resisting doors

It has been proposed to assess the use of the Norsound glazing systems with the following, generic, timber based fire resisting doorset types.

This report will only consider the installation, glass type and aperture size for each Norsound glazing system.

The fire resisting door blank must have been previously tested with installed glazing at a UKAS accredited laboratory or assessed for use with glazing by Exova Warringtonfire. The installation method, glass type and aperture size must be supported by the relevant test/assessment documentation for the door design. The aperture size must not exceed whichever is the smaller of that stated for the particular door type or that stated herein.

For all other details the full construction requirements in the relevant door blank manufacturer’s test evidence or assessment documentation must be complied with.

The following timber based door types can be considered for use with the Norsound glazing systems subject to the provisos above:

1. Graduated density chipboard and three layered particleboard door blanks

2. Softwood or hardwood laminated door constructions with tested or assessed cellulosic facings

3. Stile and rail constructions with flax, chipboard or timber based cores

4. Stile and rail constructions with non-combustible sub-facings

5. Traditional timber joinery.

3.3 Assessed Glass – General

Glazed openings must not be less than the prescribed distance from any door edge. Multiple apertures are acceptable within the permitted glazed area, with a minimum dimension of 80mm between apertures, subject to specific restrictions for the door type (i.e. stiles, rails, internal frame-work etc.). Aperture shape is not restricted, providing the glazing system and beads are compatible with that shape.

The full installation requirements in the assessment documentation relevant to the chosen doorset must be complied with.

Data sheets for each of the Norsound glazing systems are contained in section 5.
