Sound attenuation

An important feature particularly for buildings near busy crossroads, railways and airports is perfect sound insulation property of windows. Improving sound insulation properties is attained through the use of various glass types. Rw = 32dB – standard Rw = 35dB – near roads Rw = 38dB – near busy roads Rw = 41dB – near […]

Heat transfer coefficient

The most important window and door technical parameter. It expresses the amount of thermal energy that penetrates through window or door. Its volume is influenced by thermal properties of frame and glazing. Thus the lower the value of heat transfer coefficient, the better the thermal-insulation properties are.

Building depth

It means thickness of window frame in mm. As a general rule, standard products with larger building depth have better thermal-insulation properties. As to composite windows the thickness of window frame including aluminium cladding is regarded as building depth.

Glossary

frame – fixed part of window installed in the wall in which leaf or fixed (unopenable) glazing leaf – openable, hinged or sliding part of doors and windows. Glazing is located in it. Engineered timber – basic semi-finished product for manufacturing of wooden windows. It is a multilayer laminated timber the cover lamellas of which […]

Rabbet-free window design

Rabbet-free windows are specific as to their genuine design. No hardware parts can be seen and leaf is matched with frame across the board. Special hardware are used for rabbet-free windows that put the leaf before the frame.

Hardware for sliding doors

HS sliding doors are equipped with lift-slide hardware characterized by high handling comfort, reliable protection against robbery and variable ventilation. We also offer special solutions for slit ventilation, suitable floor thresholds, adjustable speed limiters, and hardware with motor control. design alternatives: manual control – control using a handle and manual sliding. motor control – this […]

Barrier-free thresholds

They separate thermally inner and outer space, prevent loss of heat and help attain significant energy savings. In addition, our floor thresholds are characterized by high stability. With well insulated floor threshold you can reduce heat flow in bottom connection to balcony windows, entrance doors and HS sliding windows. As to balcony doors the threshold […]

Glass spacers

They are located in insulation glazing along its perimeter and join individual glass panes into one unit. Glass spacers are either metal, plastic-metal or plastic. alternatives of glass spacers Metal spacers are either stainless or aluminium. Plastic-metal spacer is a spacer profile for manufacture of insulation glass belonging to the family of “warm edge” profiles […]
