Chartwell Green UPVC Window Style 12

Window Hinges

As standard, all opening windows are fitted with stainless steel friction stays allowing the window to stay open in the required position.

• Fire escape hinges or egress hinges for emergency exit requirements allow the window sash to open almost 90 degrees. Available on side hung windows only.
• Window restrictors prevent the window opening to a maximum of 100mm to provide child safety. Available on both side and top hung windows. Supplied separate.
• Easy clean hinges combine fire escape requirements with an easy clean feature to access the outside of the window easier for cleaning. Available for side hung windows only.

Window Security

Standard

As standard, windows are fitted with dual action espag roller cams providing a high security locking system.

Shootbolt Upgrade

The optional shootbolt locking system provides exceptional security using a combination of steel roller cams and shootbolts and is guaranteed against mechanical failure for 10 years.

PAS24 accredited and Police preferred specification - the highest level of protection against forced entry.

Our shootbolt locking systems are covered by a guarantee of up to £7,500* in the event of a break-in.

PAS24 Enhanced Security Upgrade

In addition to the shootbolt upgrade, the window will be fitted with Elite Stay Guard hinge protectors and screw retainers in the window frame and sash. PAS24 is required for Building Regs Part Q for new builds and extensions. Note, windows in easily accessible locations will also require laminated glass.

Trickle Ventilation

Trickle vents allow you to control ventilation and air circulation, helping to reduce condensation and mould. They provide you with a small amount of fresh air into the building without letting a lot of heat escape.

15th June 2022 Part F (ventilation) Changes

If there are already vents fitted on the original windows, then you can fit the same sized vents on the new windows. For example, 2500mm2 EA vents can be replaced with 2500mm2 EA vents or higher. Just remember that the airflow cannot be decreased.

If the existing windows do not have vents, then the replacement windows must have vents fitted to meet the requirements of the revised Approved Document F. For houses in England, that means a minimum airflow of 8000mm2 EA in habitable rooms and 4000mm2 EA in non-habitable rooms.

All windows for new build properties and extensions are required to have adequate background ventilation whether this is by trickle vents, purge ventilation or extraction.
