Delta Combi AL FW Fixed Window
Product Specification
FW - Fixed WindowsFeaturesFW gives maximum light area and can be coupled in conjunction with all Delta Combi AL products.
 
Creates clean and uninterrupted lines and can be used in a vast number of combinations with opening light inserts within fixed light.
 
In addition intermediate transoms and mullions can be incorporated as necessary to provide features and guarding where needed. For fixed windows removable beads can be supplied as an option,
to allow replacement of the glazing element from within the building, avoiding the need to supply external access to carry out the task. This is a true benefit where access is limited or difficult. 
HardwareN/A Locking system - Espagnolette
N/A 
HandleN/A Construction
Double 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. 
Sealing
Sealing 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.  RestrictorsN/A 
Trickle vent The 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.

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 a U-value of 1.61W/m2/K
