Product reference: PRO TEC Classic System
Type: Windows and doors to be of a true composite construction
which does not allow for any timber component to fall within the
wet-zone of the units. Aluminium clad timber construction is not
acceptable. All elements to be thermally-broken, dual-sealed to
provide an average overall U Value of no more than 1.56 W/m2K
Glazing rebate: To suit a 28mm glazing unit with the ability to fit a
glazing unit up to 36mm on opening lights and maximum of 42mm
on fixed lights.
Profile: Standard 54mm x 60 sash, 42mm x 116mm frame, 58mm
x 116mm transom and mullion. Where required overall internal
timber profile depth, must be able to range from 116mm to
250mm.
When joining multiple elements, the system must have option to
maintain a 58mm transom and mullion section, via use of 16/42
combination of timber profile.
Generally: PRO TEC Classic side hung, top hung, tilt & turn, fully
reversible, sliding and fixed lights. Butt hinges / friction stays,
where required (refer to architects drawings).

Double glazed sealed units to give overall maximum average U
value of 1.1W/m2K. Triple glazed sealed units to give overall
maximum average U value of 0.9W/m2K
U values: To meet the target emissions rate in Building Regulations
Approved Document L: 2006, manufacture to have allowed for
windows to be glazed with double glazed units incorporating low
emissivity coated glass and an argon gas filling within the glazing
cavity.
When glazed with standard 4-20-4 insulated units PRO TEC Classic
window system will achieve an overall U-value of 1.56 W/m2k when
calculated in accordance with BS EN ISO 10077: Part 1: 2006. The
window size used for this calculation is 1230mm x 1480mm as
specified in BS EN ISO 12567: Part 1: 2000.
Glass to glass corners must be stepped glazing, which provide a
very slim corner joint.
Acoustic Rating: As required windows to be glazed with 28mm
sealed units comprising 4mm clear outer/20mm argon cavity/4mm
clear super low-e inner to provide a minimum Rw rating of 31dB
when tested in accordance with ISO 140-3:95 “Acoustics –
Measurement of sound insulation in buildings and of building
elements – Part 3: Laboratory measurement of airborne sound
insulation of building elements” at a size of 1185 x 1185mm,
Manufacturer to provide report of the individual frequency ratings
for approval.
Glass thickness and type to suit application. Laminated / toughened
to BS6206 & BS6262 where applicable
Manufacturer as per architect’s specification.
-Ironmongery / Accessories:
o Side and top hung projecting sashes to be fitted with a key locking
espagnolette handle and a non-locking restrictor.
o Fully reversible sashes to be fitted with a key locking espagnolette
handle and an integral hinge restrictor.
o Turn tilt / tilt slide / sliding sashes to be fitted with a key locking
espagnolette handle.
o Terrace doors opening out to be fitted with a key locking
espagnolette handle which operates a brake on the head.
o The window ironmongery to be generally manufactured from zinc
chromated steel with a matt chrome finish.
o Locking espagnolette brushed chromium plated (by FIX)

Titon Trimvent 90 if required to be surface mounted on the timber
framing profiles as indicated on the enclosed specification
schedules. Each trickle ventilator to provide an “Equivalent Area”
of 2510mm2 in accordance with EN 13141: Part 1: 2004 as
required to be measured by Building Regulations Approved
Document F: 2006.
Should a measurement of ‘Free Area’ be applicable to your project,
each ventilator will provide 4000mm2. Delete and replace with:
Free Area of trickle ventilators to provide 4000 mm2 per ventilator.
The system to have the ability to provide the option for Acoustic
trickle vents as per the architects drawings.
-Fixing:
o
To manufacturers recommendations by approved PRO TEC Installer
INSTALLATION
o
All PRO TEC windows and doors are to be installed vertically into
prepared openings. All PRO TEC products are internally glazed
except fixed lights which are externally glazed.
o
Suitable fixing grounds or interface materials to be provided by
others which are immediately adjacent to the product and allow
point loads to be used at centres in accordance with the standard
fixing positions.
Window and door elements are not to be utilised as structural
elements and no loads shall be imposed upon them other than
which they are expressly designed for. Their own dead weight and
the wind loads acting upon them (both individual and collective
frames) require to be transferred back to the grounds or interface
materials to which they are fixed.
Should the grounds be inadequate to take such point loads to
comply with BS 6399 Part 2, reinforced fixing brackets, a change in
substrate materials or re-design may be required, this to be
confirmed during manufacturing design stage and in conjunction
with the approved installer.
