The exceptions are Lift-Out Units & Fixed units, which as the names imply, are either Lifted In & Out or are Permanently Fixed! The Secondary Glazing units are then fitted inside of the existing primary windows & doors. Once fitted, Secondary Double Glazing has been created – it is a misconception that Secondary Glazing itself is Double Glazed.

How does secondary glazing look?

Because of the inherent strength of aluminium the panel & framing sections are considerably smaller than Timber or uPVC sections. Our standard finish is White, we also stock a Brown & a Light Oak Wood-grain finish & can colour match to any RAL colour.

We have carefully designed our systems to be discreet & unobtrusive – in fact once installed in most instances they are virtually invisible – which can be a big problem for us in our promotional & advertising material!

Once they are fitted you can forget about them & get on with your life, enjoying the same Uninterrupted Views from your Windows whilst enjoying the Benefits of a Warmer, More Comfortable, Securer, Less Noisy Home – with Reduced Heating Bills as the Finishing Touch!
