Secondary Double Glazing

Secondary Double Glazing

Why choose secondary double glazing?

Easy Option
Secondary double glazing is a quick and easy way to reduce noise, draughts and heat loss and improve insulation without replacing windows: it’s a ideal for listed buildings or other properties which have restrictions placed upon exterior changes.
Quality
CRK's secondary double glazing system uses sturdy extruded aluminium alloy sections and 4mm thick glass.
The moving panes are sealed to the frames using long lasting woven weather piles so they slide easily and keep the heat in and weather out.
Versatile
CRK can fix secondary glazing to virtually any window; from hinged units and horizontal sliding units for casement windows to vertical sliding secondary glazing for sliding sash windows.
All our secondary glazing is operated using spring balances, sliding panels or tilt facilities that make them easy to open and clean. We can even provide fixed panes or lift out units too.
Our choice of styles and colour shades is unrivalled.
 
Subtle
All CRK secondary glazing is made to the exact specifications of your existing windows, making any additions almost completely invisible from the outside. They are also demountable should you need to remove them for any reason.
