Delta Combi AL TT180 Top Turn 180°
Product Specification
TT180 - fully reversible outward opening windowsFeaturesTT180 are fully reversible outward opening windows. The windows turn outside-in for easy cleaning with-out taking up any room space. The special hinges mechanism is designed to work as a
simple cantilever principle, allowing the sash to swing up to 180º. In multi level buildings this means a significant saving in cleaning costs, as well as a high degree of convenience.HardwareTT180 windows are fitted with PN-UNI hinge mechanism manufactured from high grade steel. It is electro galvanized and finally treated with a chrome finish to create maximum protection against corrosion. Major pivots are carefully lubricated to ensure durability and long surface life. All sliders are made of nylon coated material to ensure minimum of resistance and maximum durability during operation.
 
The mechanism is specially developed for the UK market and meets UK demands for strength and function to BS 6375: part 2 1987 – BS7950: 1997, sec. A6
Locking system - EspagnoletteSupplied from FIX AB the Espagnolette system with minimum two point locking with added dual position keep, allowing controlled ventilation. The system is tested according to SS3535 confirming espagnolette and keeps are produced from a corrosion resistant
material with an extra protective chromated layer. The Espagnolette has been tested to a 50,000 open-close cyclic test for enhanced performance and minimum maintenance.HandleAs standard a cranked HOPPE London non-lockable handle is supplied available in various colours. Lockable available on request 
ConstructionDouble tenon corner joints in the timber profile with the option to add mullion and transom
configurations, creating split glazing areas. The integrated aluminium and timber composite perimeter frame is mechanically connected with mitred and crimped corners. The sash frame aluminium section being continuously retained around the timber sash in an extruded and mechanically fixed carrier frame. 
Frame sizesThe windows are manufactured from European FSC certified timber. The softwood is carefully chosen and sawn before kiln dried to approximately 14% water content. Thereafter the timber is cut, finger jointed together to create a straight piece of timber
with no knots. All frame depths can be delivered in 100mm, 115mm (standard), 130mm or 145mm for constructional strength. 
SealingSealing is achieved by a continuous single gasket, or double gasket for enhanced performance. The gasket is compressed into a rebate by the sash frame ensuring maximum compression and
weather tightness when subjected to severe weather conditions. 
RestrictorsFor security reasons the hinge system has a built in two position restrictor preventing the window from opening more than approx. 100mm in the first locking point (for everyday ventilation). The
same restrictor also holds the window in position when the window is in the fully reversed position, creating security and freeing both hands during cleaning. For alternative restricted openings,
a special “Blocking” device can be offered. Please refer to PN3906. 
Trickle ventThe adjustable standard Titon hi-lift trickle vent system is positioned at the underside head of the frame to make the maximum out of fresh incoming air. The ventilator is concealed from the outside by an external hood/drip detail incorporating an integrated inset mesh.

Factory finishTimber
Our internal standard colour range is:
White - RAL9010
Clear lacquer – T.M. 7130
Mahogany – T.M. 1530
Pine – T.M. 367
Alternatively any standard RAL colour (not metallic) is available.
 
The paint is a 2 layer water based paint and with a total of ~110 micron (dry) it will ensure a maximised durability for many years if the windows are regular maintained in accordance with suppliers
recommendations.
 
External aluminium finish
External aluminium cladding coatings:
1) Polyester powder coating Minimum 60 micron thickness standard in any standard RAL colour available (excluding metallics). Standard Gloss 30% (optional 77% gloss upon request)
2) Anodised finish Min/max 25/35 microns in our standard colour range
Natural Silver (optional Bronze or Champagne upon request).PerformanceThe windows have been tested to meet the following requirements;
BS6375: Part 1: 1989 Performance of windows – Classification for weather tightness
Air permeability 300pa (single gasket) 600 Pa (double gasket)
Water Penetration 300pa (single gasket)600 Pa (double gasket)
Wind resistance 1200 pa (single gasket) 2000 Pa (double gasket)
Exposure category 1200 pa (single gasket) 2000 Pa (double gasket)
BS6375: Part 2: 1987 Performance of windows – Specification for operation and strength characteristics. 
Thermal insulationThe thermal simulation ensures compliance to British and Scottish standards. Calculated U-values as stated for each window type on the final factory order confirmation can be requested.
Our low-E argon filled glass units (4-20-4) create a U-value of app. 1.70 W/m2/K (Double glazing) and 1.50 W/m2/K (Triple glazing).
Precise figures varies dependant upon glazing specification, size etc.
 
The same specimen with 6,4mm laminated glass created aU-value of app.1.61 W/m2/K.
