Description

Sash Security Windows

Security sash windows London are suitable for replacements in historic listed buildings or in conservation areas. Modern sash windows are also available for new contemporary buildings. Traditional English timber sliding sash windows, which look just like originals yet meet the new compulsory standards, that is what we produce and supply. Original security timber sash windows consist of two glazed sashes, which slide vertically in a timber frame, supported by cards that are balanced with lead weight. In windows with spiral balances the sash can slide and tilt. These windows usually have thin glazing bars, decorated with oval or lambs-tongue mouldings, and shutters were often positioned either side with similar detailing to provide security or warmth. These windows are usually built from wood and are painted. In our-range of colours there is a choice of opaque and translucent, according to Sikkens colour palette. They are double – glazed. The internal double-glazing makes them extremely difficult to break into. They are also glazed from the inside, which means the glazing cannot be removed from the outside. We fit high quality two type of balances: spiral and weights. In addition we can supply a range of linings, window boards and architraves in matching material. Our security timber sash windows are the best in whole London

Why to choose our security sash windows?

Timber is the best material for character, warmth, comfort, durability, window/door construction, heat retention.

The main timber generally used: oak (is used for sills and also as building material for windows), pine, mahogany. We are using laminated triple-layer wood . Three layers are used because this technology prevents the window frame from crooking and increases the lifetime of the windows. The outer layers are radial or half radial cut and this method protects window surfaces from wood cleavage.

Security sash windows London: Glass and Glazing

Our timber windows and doors are glazed with double-glazed units which incorporate an advanced thermally insulating glass to provide extremely low U-values. The efficiency is further improved by filling cavity with Argon Gas and low conductivity Warm Edge Spacer bars to minimise heat loss on the edges and results in centre pane U-values of 1.0 W/m.

High light transmittance (75%+) maximises the entry of sun light into your home. As well as our range of clear glass options we also have a wide choice of Etched glass and extensive obscure patterned glass available in any of our windows, all of which have different options and provide optimised performance.

We can offer glass types to meet requirements:

  • Toughened – increase strength and safety
  • Laminated – provides additional security over toughened unit
  • Obscure – gives privacy and style to windows
  • *available in a wide range of patterns

To improve security, all our timber sash windows are glazed internally which makes it impossible for intruders to gain entry by removing the glass.

All double glazed units are designed with drainage and ventilation channels which helps prevent double glazing from misting and failure of units which can occur in conventional system when glazing units are allowed to sit in water is trapped in a frame.

Decorative bars inside of glass packs – profiles of different colour, which are used for dividing glass according to the required density, mounted inside of insulating glass units.

Security range

A wide choice of security laminated glass according to EN 356

Testing and Classification of resistance against Manual Attack EN 356 is a European Standard for glazing to withstand an intruder attack, it has two resistance levels, the lower levels, P1A – P5A, also use the drop test but the higher resistance levels test using a hydraulically driven hammer and axe head, to replicate an actual attack. The higher resistance levels are P6B, P7B and P8B which require the samples to withstand 30/50, 51,70 or 71+ sledge hammer and axe blows respectively, before a 400mm square aperture is created.

The Lower Resistance Level

This level represents a manual attack using a blunt instrument such as a hammer. The test comprises dropping a 100mm steel ball (4.11kg) from various heights.

To pass the test the ball must not penetrate the glass.
