38.2.3 Sheet glass shall be p<strong>at</strong>ent fl<strong>at</strong>tened glass <strong>of</strong> best quality <strong>and</strong> for glazing <strong>and</strong> framing purposes shall conform to IS :<br />
1761. Sheet glass <strong>of</strong> the specified colours shall be used, if so shown on the detailed drawings or so specified for<br />
important buildings <strong>and</strong> for panes with any dimensions over 900 mm., pl<strong>at</strong>e glass <strong>of</strong> specified thickness shall be<br />
used.<br />
38.3 Pl<strong>at</strong>e Glass :<br />
38.3.1 When pl<strong>at</strong>e glass is specified, it shall be `Polished p<strong>at</strong>ent pl<strong>at</strong>e glass' <strong>of</strong> best quality. It shall have both the surface<br />
ground fl<strong>at</strong> <strong>and</strong> parallel <strong>and</strong> polished to obtain clear undisturbed vision <strong>and</strong> reflection. The pl<strong>at</strong>e glass shall be <strong>of</strong><br />
thickness mentioned in the item or as shown in the detailed drawing or as specified. In absence <strong>of</strong> any specified<br />
thickness, the thickness <strong>of</strong> pl<strong>at</strong>e glass to be supplied shall be 6 mm. <strong>and</strong> a tolerance <strong>of</strong> 0.20 mm. shall be admissible.<br />
38.4 Obscured Glass :<br />
38.4.1 This type <strong>of</strong> glass transmits light so th<strong>at</strong> vision is partially or almost completely obscured. Glass shall be plain rolled,<br />
figure, ribbed or fluted, or frosted, as may be specified or as required. The thickness <strong>and</strong> type <strong>of</strong> glass shall be as per<br />
details on drawings or as specified or as directed.<br />
38.5 Wired Glass :<br />
38.5.1 Glass shall be with wire netting embedded in a sheet <strong>of</strong> pl<strong>at</strong>e glass. Electrically welded 13 mm. Georgian square<br />
mesh shall be used. Thickness <strong>of</strong> glass shall not be less than 6 mm. Wired glass shall be <strong>of</strong> the type <strong>and</strong> thickness<br />
as specified.<br />
38.6 Double Glazed units :<br />
38.6.1 Double glazed unit shall comprise <strong>of</strong> two glasses, <strong>of</strong> appropri<strong>at</strong>e thickness <strong>and</strong> absolutely machine-cleaned on both<br />
sides, with an air gap <strong>of</strong> 12 mm .in-between. The space between the two glasses is kept totally dry, avoiding any<br />
condens<strong>at</strong>ion by sealing the space with elastomeric sealant. Thus in all, it is an insul<strong>at</strong>ing glass unit <strong>of</strong> around 20mm.<br />
thickness.<br />
38.6.2 It shall be suitably used for any kind <strong>of</strong> Doors <strong>and</strong> Windows, in all areas <strong>of</strong> work <strong>and</strong> residences. It shall be absolutely<br />
<strong>and</strong> clearly transparent, giving the following advantages :<br />
1) Total light penetr<strong>at</strong>ion, but with dust <strong>and</strong> he<strong>at</strong> insul<strong>at</strong>ion.<br />
2) Noise insul<strong>at</strong>ion.<br />
3) 25% saving in electricity due to he<strong>at</strong> insul<strong>at</strong>ion.<br />
4) Crystal clear transparency.<br />
M-39 Acrylic Sheets :<br />
39.1 Acrylic sheets shall be <strong>of</strong> thickness as specified in the item <strong>and</strong> <strong>of</strong> specified shape <strong>and</strong> size, as the case may be.<br />
Panels may fl<strong>at</strong> or curved. It should be light in weight. It shall be colourless or coloured or opaque, as specified in the<br />
item. Colourless sheet shall be as transparent as the finest optical glass. Its light transmission r<strong>at</strong>e shall be about<br />
95%. Transparency shall not be affected for the sheets <strong>of</strong> larger thickness. It shall be extremely resistant to sunlight,<br />
we<strong>at</strong>her <strong>and</strong> low temper<strong>at</strong>ures.<br />
39.2 It shall not show any significant yellowing or change in physical properties or loss <strong>of</strong> light transmission over a longer<br />
period <strong>of</strong> use. The sheet shall be impact resistant also, sheets should be <strong>of</strong> such quality th<strong>at</strong> they can be cut, bent<br />
<strong>and</strong> jointed, as desired. Solution for the joints shall be used as per the requirement <strong>of</strong> manufacturer.<br />
M-40 Particle Board :<br />
40.1 The particle board used for face panels shall <strong>of</strong> best quality free from any defects. The particle boards shall be made<br />
with phenolmaldehyde adhesive. The particle boards shall conform to IS : 3087 "<strong>Specific<strong>at</strong>ions</strong> for wood particle<br />
board for general purpose". The size <strong>and</strong> the thickness shall be as indic<strong>at</strong>ed.<br />
40.2 Particle board shall be made completely from Teakwood <strong>and</strong> shall be bonded with BWP type Phenol <strong>For</strong>maldehyde<br />
synthetic resin to give a fl<strong>at</strong>, strong <strong>and</strong> homogenised panel.<br />
40.3 It shall be durable <strong>and</strong> shall have smooth surface so as to take any type <strong>of</strong> surface tre<strong>at</strong>ment, like polishing, painting,<br />
lamin<strong>at</strong>ing or veneers. It shall be fire resistant, we<strong>at</strong>her resistant, termite <strong>and</strong> insect resistant. It shall be dimensionally<br />
stable, structurally strong <strong>and</strong> acoustically superior.
