Pilkingtons 'K'




is THE name in Glass, it is probably the most well known name in glass the world over, and WE at Abbey are proud to use it.

So what is Pilkington 'K' glass you might well be thinking, don't worry, you are not alone.

Pilkington K Glass™, which usually forms the inner pane of a double glazing unit, allows less heat to escape through your windows than ordinary glass. Thanks to a special energy saving coating which lets the sun's rays through, but reflects heat from fires and radiators back into your home. Heat which ordinary double glazing allows to escape.

The glass in your windows absorbs heat then radiates it again on the colder, outside, surface. Pilkington K Glass™ has what is called a low emissivity coating on the surface that faces into the air gap of the double glazing unit.

Low emissivity means the coating is a poor radiator. The heat absorbed by the coated glass is inhibited from radiating across the air gap and then from the outer pane to the cold outside world. Instead the heat is reflected back into the room by the coating.

It works in a similar way to a sheet of reflecting foil placed behind a central heating radiator which, as you know, bounces the heat back into the room.

It makes double glazing as effective as triple glazing and cuts fuel bills.

So what does it do then? Pilkington K glass will

Reduces condensation
Condensation forms when warm, moist air comes into contact with a cold surface, such as conventional glass. The energy saving coating on our glass actually makes the surface warmer to the touch, so condensation is reduced.

Eliminates cold spots
Ordinary glass offers poor insulation, so uncomfortable cold spots close to windows are a common problem.

Double glazing can alleviate this to an extent, but only double glazing with Pilkington K Glass™ has the total solution. It provides superior insulation, making the inner pane of your window much warmer. This eliminates cold spots, and increases useful floor space.

Is perfect for conservatories
Better insulation and no cold spots near windows makes Pilkington K Glass™ perfect for conservatories. In fact, it will typically keep an unheated conservatory comfortable for a greater part of the year than ordinary double glazing. Allowing you to make the most of your conservatory all year round. Pilkington K Glass™ can also be toughened or laminated for safety and greater security, We use only 100% safety glass in all our conservatories, so you can rest assured that you get the best in performance, quality, and safety..

Increases comfort
The unique properties of Pilkington K Glass™ mean you can turn down your thermostat and still remain just as comfortable. This can result in savings over and above those shown in the table.

The technically minded among you might be interested in the specification below.

  • A true low emissivity glass (emissivity less than 0.2)

  • Specifically designed to reduce heat loss through a window

  • Low emissivity coating allows the ‘free’ short wave energy from the sun to enter the building, but acts as a barrier to the escape of expensive long wave energy from internal heat sources

  • Excellent thermal insulation characteristics, reducing heat loss by 30% over ordinary double glazing

  • Windows can become a positive contributor to a building’s heating needs by optimising ‘free’ heat from the sun

  • Can be used in Pilkington Insulight

  • Pilkington Insulight ™ , incorporating Pilkington K Glass ™ is as efficient as triple glazing and can achieve U values as low as 1.5W/m2K

  • Pilkington K Glass ™ can be combined with solar control glasses to offer full energy management solutions

  • Neutral colour in transmission and reflection

  • Available in 4 and 6mm thicknesses and 6.4mm laminated

For those of you who are not technically minded, let us rpeat that Pilkington K glass is the best money can buy, saves you money on heating, keeps your conservatory warm and saves the planets resources, and we fit it as standard!
