All glazing we are fitting in our windows and doors are Law E Double glazing units.



One chamber heat insulating glazing unit comprises two glass panes, including one Thermofloat glass pane with invisible layer of inert metals combination (so-called “low emission layer”). Two chamber heat insulating glazing units comprise two Thermofloat glass panes. The space between glass panes is filled with argon or krypton gas, which further reduces heat transfer coefficient Ug. Protection against gas leak at the glass pane perimeter is ensured by warm distance frame with two-step sealing of plastic.

Spacer bars.

Warm Edge Technology

Warm Edge Technology is a term given to a slightly different type of spacer bar, the term warm edge is based on the fact that the construction is fabricated and designed to conduct less heat or cold than the traditional spacer tube used in standard sealed units. We are using  Chromatech or Termo TGI bars proposing different colors:

Aluminumramka aluminiowa

Coloursspacer bars

Available colours of spacer bars: grey(RAL 7035), dark grey (RAL 7040), black (RAL 9005), brown (RAL 8003), dark brown (RAL 8016) white (RAL 9016)

Spacers bars comes in standard thickness: 8, 10, 12, 14, 16, 18, 20, 22, 24mm.

In order to achieve traditional looking double glazed windows with glazing bars we use the duplex –  spacers system.  The narrow timber glazing bars (duplex bars) are fitted to outer faces of the glass both on the back and front. Inside the double glazed unit we fit false spacer bars between the glass panes to give the appearance of individual units. By using special spacers for duplux bars built in the double glazed the minimum thickness of cavity has be at lest 12mm.

This system is very effective and successful way of matching original features but meeting the U values required to comply with today’s building regulations.


Toughen Glass

Toughened glass means safety and is required according to Building Regulations to all areas below 800mm FFL (Finished Floor Level). When it breaks, the pane is shattered into tiny pieces with blunt edges. This characteristic makes toughened glass particularly suited for use in highly sensitive places, with a high risk of being broken or exposed to high insulation – which means a big increase of internal thermal stresses.


    • bending strength is five times higher in comparison with non-toughened glass,
    • resistance to thermal shock and heating caused by solar radiation,
    • decreased risk of injury when the pane is broken.



Laminated glass

It is a type of safety glass that holds together when shattered in the event of breaking.  Two or more glass layers are held in place by an interlayer usually polyvinyl butyral (PVB) or Ethylene-vinyl acetate (EVA). The interlayer keeps the layers of glass bonded even when broken, and its high strength prevents the glass from breaking up into large sharp pieces. When the glass is damaged it showed a “spider web” cracking pattern.

Self Cleaning Class

We can provide a sealed unit which has been treated with a self cleaning coating, reducing the maintenance requirement for any given installation. These units are particularly suited to hard to reach places where access is restricted
