Heritage Products Glazing and Colour Options

Glazing Options

When it comes to glass, and glass designs you can literally have almost anything you want. Our standard glass is clear, 90% argon filled sealed units (low-E, en=0.05, soft coat), 1.2 centre pane U-value.

In the Heritage system you can have double glazed sealed units up to 24mm in depth (these units are not wide enough to take integrated blinds). The Heritage Windows are available with square or diamond leaded glazing that can be soldered for a more authentic look, georgian bars that are fitted inside the sealed units, astragal bars, which are fitted on the outside of the glass with a dummy spacer.

See some examples below:

Colour Options

Our products are all painted with a hardwearing polyester powdercoat paint, the paint is built to last and baked onto the aluminium. We only use approved Polyester Powder Coat Specialists, and can therefore offer a ten year guarantee. This finish is high quality and low maintenance, only requiring an occasional sponge down.

Our Heritage Windows are available in a standard white, black, brown and a black on white dual colour. Dual colour is where you can have different colours inside and out, for example dark grey outside and white inside. Our KL colour range, a silver anodised finish and some 'Hammerite' style textured paint finishes are also available. If these colours are not what you are looking for then you can have you windows painted in any of over 200 single or dual RAL colour finishes.
