Secondary Glazing

Secondary glazing is Aluminium glazed frames that fitted to the inside of your property against your existing windows. This can very useful if your existing windows cant be removed (windows in listed buildings) or don’t want them to be replaced. If your existing windows are draughty or noisy fitting secondary glazing will reduce both the noise and the draft. If your existing windows are single glazed adding secondary glazing will double up the glazing, as your windows would then have two glass barriers, increasing the termal properties as well as reducing the noise level.

Secondary glazing is designed to blend in with your existing windows. Made from Aluminium the framework is slim line in appearance. Vertical and horizontal bars can be designed to be inline with your existing window framework. Various colours are available including White, Silver and Brown. Toughened safety glass or patterned glass can be fitted. Clip or Fitch locks can be fitted if required.

Secondary glazing units are fitted from inside your house. The frame is either fixed to you existing window frame or into the reveal plasterwork. They are designed to seal against the plaster or against your existing window. Polypropylene weather pile is against sliding panes.

The following types and designs are available:

Two and Three pane Sliders

Horizontal sliding panes slide easily side ways on skids. All panes can slide or combinations of sliders and fixed panes can be specified. As the panes slide sideways they will not open into your living space.

Vertical sliding

Vertical sliding panes will match your existing Georgian Box sash windows. For small windows shoot bolts can be fitted or for larger windows Spiral balances can be fitted to hold the weight of the sliding panes.

Lift outs and Hinged

Panes can be lifted out for access or for cleaning and lifted back into position. Hinged panes are hinged on one side and open into you room for easy access or to clean your existing windows.
