Slim Double Glazing
- Cool in Summer, Warm in winter
The utilization of slim double glazing effectively creates an insulating barrier between two panes of glass, thereby impeding the transfer of heat through the window. This results in a heightened level of energy efficiency, as heat is prevented from escaping.
- Save those pennies.
If you replace all of the single glazed windows with energy efficient Slim double glazing, you could save around 20% per year on your energy bills.
- Save the planet!
As you will be losing less heat, you will be using less fuel. This means that not only will you be saving yourself money, but you'll be doing your bit to save the planet too. Less fuel consumption means less carbon dioxide emissions which means a smaller carbon footprint.
- Get a good nights sleep.
Slim double glazing, as the name suggests, is much thicker than its single little brother. This means that not only is it good at stopping heat escape, its also good at stopping noise getting in. Enjoy the peace and quiet, knowing you're saving money and energy at the same time.
- Feel more comfortable.
By reducing heat loss, there will be less draughts and cold spots in your home. Double glazing also helps reduce the amount of condensation that builds up on the glass panes on the inside of your windows.
- Increase the value of your home.
As energy efficiency becomes more and more desirable in the home, many buyers or renters will be looking to make sure their new home is double glazed. Installing double glazing now, even if you are not planning on selling your home any time soon, means that you will reap the benefits and should also help make your property more appealing to potential buyers.

Units can be installed in traditional windows and doors, whilst allowing for glazing bars as narrow as 21mm, with putty line detailing to match the existing. Slim approved installers & suppliers
Slim Double Glazed Units, featured in Grand Designs.
Unique 7mm perimeter seal depth. From any distance it looks like single glazing. By using and maximizing the latest technology it is possible to construct a double glazed unit with very small cavities or space between the glasses with a 7mm perimeter seal depth and selected insulating inert gas cavity to obtain U-Values to comply with Building Regulations and comparable or better than U-Values obtained by standard units with much wider cavities this is a specialist system, and like all options of double glazing sash windows is quite costly, also the units are filled with krypton inert gas and this is very expensive but achieves a u value in very small units than can normally only be achieved with large 28mm units filled with argon gas.
The sealant used is a special product, again is quite costly and last but not least the weights need to be changed to lead weights. Cast iron weights are too long, and loose the amount of travel the window can make.
- Self Cleaning Glass
The Pilkington Activ™ Range: A Two Step Cleaning Process After years of development, Pilkington Activ™ is the world's first self-cleaning glass to use a microscopic coating with a unique dual-action.
The first stage of the cleaning process is "photocatalytic". In this stage the coating reacts with daylight to break down organic dirt.
This self cleaning action can be seen on a Lotus Leaf and is referred to as the 'lotus effect' with very high water repellence referred to as Hydrophobicity (Self Cleaning Action). The surface of the lotus leaf is not flat but consists of closely formed microscopic projections providing a variety of very different surfaces.
- Cost of Slim glazing system.
As an example of pricing a 0.9 m x 1.7 m sash window with four split panes and new lead weights fitted would be £675.00 inclusive.
The Slim Double Glazed Units are fabricated utilizing a 4mm transparent outer pane, accompanied by a chosen cavity of either 4mm, 6mm, or 8mm. The broader cavity enhances the insulation, and the selected cavity is filled with an insulating inert gas, which is only effective in smaller cavities. The inner pane is composed of 4mm Low Emissivity glass.
The emissivity coating is on the inside face into the cavity and reflects the long wave radiation or heat back into the room. The warm edge technology perimeter spacer incorporated, ensures insignificant differential insulation value between edge and centre of glass. Today it is necessary for Slim double glazed units to comply with Building Regulations (noted below) in respect of U-Values which are slightly different between Scotland and England. Slim Double Glazed Units can comply with both these regulations as noted.

Window weights for sash windows require adjustment when Slim or any double glazed units are fitted to the sashes, which approximately doubles the weight. The best weights are extruded lead weights with a center hole for the cord, for easy adjustment and cutting to any length.
The majority of sash windows currently in use are equipped with cast iron weights. However, if these weights are replaced with lead weights of a similar diameter or size, the lead weights will be approximately twice as heavy as the cast iron ones. This replacement guarantees that the weights will be of similar length, resulting in the sashes having an equal amount of opening travel.
