Your home is the biggest single investment you'll ever make, and choosing replacement double glazed windows and doors is a big step. After all, your new windows and doors won't just make your home more attractive and comfortable, they will also add to its value.

Whatever the style of your home, we'll ensure that the window and door design blends in beautifully.

You can even have windows to complement your interior decor - for instance, a clean white finish on the inside and either woodgrain or colour on the outside.

Superbly engineered to demanding standards, the windows will give your home real style that will last for years and years.

Pilkington energiKare™

At Allerton Glass and Glazing we can offer you the only product that gives you the reassurance of Pilkington quality and that has the endorsement of the Energy Saving Trust, Pilkington energiKare™, as an optional extra.

Pilkington energiKare™ is made up of two special types of glass, Pilkington K Glass™, the UK's best selling low emissivity glass which stops heat escaping and Pilkington Optiwhite™, a special 'extra clear' glass which allows more solar heat in through the windows.

Pilkington energiKare™ is different to standard double glazing as it works in two ways. It reduces the amount of heat lost through your windows and it also allows more heat (energy) from the sun in through the window.
