The subject of the tender is the manufacture, supply and installation of thermally insulated aluminium windows as specified below.
The options available within the system regarding permitted sash sizes, sash weights and the infill thicknesses for sashes and fixed glazing are specified in the system manufacturer´s technical documentation.
The following technical requirements must be met:
Frame depth: 65 mm
Total depth of the profile system: 75 mm
Frame stop web 44 mm high
Exterior face widths:
Frame profiles 74 mm and 84 mm
Transom profiles 90 mm and 118 mm
Interior face widths:
Sash profiles 55 mm and 65 mm
Continuous insulation level in frames, sashes and infills, with insulating strips flush to the rebate
Main profile as four-chamber hollow profile, edge radius <= 0.5 mm. Overlapping sash with 5 mm overlap and rounded edges at overlap.
Centre seal of co-extruded EPDM foam, all-round with no mitred corner joints; centrally sealed at the top and adhesive-free with abutment.
Alternative versions of the centre seal
- with EPDM moulded gasket angles, sealed and with adhesive-free abutment
- vulcanised gasket frame
Outer glazing bead profiles in sashes made of polyamide, glass fibre reinforced.
The outward protruding areas of the sash profiles are completely covered with EPDM gaskets.
Outer glazing gasket in sashes with vulcanised EPDM frame, protruding not more than approximately 10 mm beyond the outer aluminium frame edges.
Fixed pane glazing system
With glazing beads and adjusting profile on the inside; total height in accordance with the height of the external glass contact web. EPDM gasket profiles on both sides, anchored in a groove of the glass contact web on the outside; inside as rolled gasket, pressed into the rebate corners, running continuously all the way around without interruption or cuts and butt jointed only at the top in the centre of the field. Selection of gaskets analogous to the sashes.
Mitred corner with system-specific, cavity-filling cast aluminium corner angles, mechanically secured with expansion function and bonded by limited volume glue injection procedure from one side.
with system-specific, cavity-filling aluminium profile connectors, limited volume glue injection.
Open joint cross-section in the blunt connection insulation zone must be sealed closed using system-specific moulded parts and injection moulding technology.
Double casement with twin sash windows, optionally with
- thermally insulated double casement profiles, with no insulation level staggering, or
- special double casement sash profile.
In both options, the upper connection joint from the meeting stiles of the sashes to the frame are covered using polyamide formed components.
Thermally insulated crossbar system
Composite profile in identical design and at identical level as the main profiles of the system.
Heat transition coefficient of the profile system:
Uf = 1.4 to 1.9 W/(m²K) in compliance with EN ISO 10077: 2003
Thermal insulation with continuous PA 6.6 (plastic) insulating strips, flush with the face of the rebate, with 25% glass fibre content and an inlay consisting of hot melt wire on the face.
The U values included in the tender must be achievable without inserting additional insulation into the profile cavities.
Proofs and certifications
The suitability of the profile bonding (insulation web) must be proven by way of a national technical approval test certificate.
Proof of the stability of metal/plastic composite profiles in accordance with the Institute for Building Technology guideline (IfBt-Richtlinie).
Composite profile manufacture is exclusively carried out at the factory. The system manufacturer, profile press plant and manufacturer of the composite materials are all certified in accordance with the ISO 9000 series of standards.
The composite profile system comes with quality assurance and a manufacturer's guarantee, also covering subsequent surface treatments (anodising, wet and powder coating).
System testing of the window system with an ift product passport as the basis for CE labelling in compliance with DIN EN 14351-1 and fulfilment of the minimum requirements for the RAL quality label RAL-GZ 695.
Airborne sound insulation as per DIN EN 20140-3
System-related branded fittings
Basic fittings are supplemented by additional parts in accordance with the size of sash and wind load. Their field of application as well as permitted sash formats depending on infill weights per unit area are specified in the technical system documentation.
The opening type options for this system series are listed under the heading "Fittings", in which the required fitting components are specified.
Drainage and air pressure equalisation
Glazing rebate bottom ventilation secured with bridging blocks designed specifically for this system. Front cavity drainage or air pressure equalisation via externally visible drainage covers.
Alternatively, front cavity drainage or air pressure equalisation and drainage in the glazing rebate with no externally visible drainage covers.
The stated specifications are based on the design characteristics, materials and processes of the WICONA - window systems WICLINE 65 evo with concealed sashes in accordance with the enclosed system description; these are contractually binding performance requirements.
