  • Laminated glass: Improved security and UV reduction preventing furniture fading.
  • Tinted anti-sun glass: Reducing solar gain, available in blue, green, grey or bronze.
  • Neutral anti-sun glass: Neutral in colour with reflective properties to reduce solar gain.
  • Self-cleaning glass: Reduces the need to clean the glass, very useful in roofs.
  • Obscure glass: Our satin deco is a stylish solution for areas requiring privacy.
  • Low-iron glass: Improves the light transmittance through glass while providing some free energy.

 


 

Dimensions

Subject to a maximum panel weight limit of 280kg, the Grand Slider II can be manufactured up to 3,000mm tall.

Panels can be fixed with moving panels sliding behind or it is possible to have all panels sliding. You can even have an extended track running parallel behind a wall or fixed screen so that panels slide completely out of sight into a pocket, providing almost 100% of the clear opening. Additional fixed panels can be 'planted-on' to both ends if required so widths greater than 20 metres can be accommodated. It is even possible to open up corners completely with a sliding corner post.

Note: If you are planning to install large glass panels suitable access and crane operation will be required.

Profile

The system works best when it is designed to provide large glass panels. Each staggered panel interlocks front-to-back with its neighbour so only a single frame, width is visible, ensuring minimal sightlines at just 83mm. Panels heights in excess of 3,000mm high and depending upon the geographical location, additional internal and/or external reinforcing profile or even integrated glass fibre strengthening bars can be incorporated to provide additional stability, whilst keeping the profile width to an absolute minimum.

Handles

The Grand Slider II sliding doors are fitted with a colour matched D-shaped handle as standard, however many of our customers choose to upgrade to the hugely popular stainless steel feature handle which achieves a more modern and contemporary look. Alternatively you can select a colour matched recessed handle which fits inside the frame of the door.

If you specify your doors with lift and slide functionality a longer colour matched handle is fitted as standard.

Security

As you would expect, the systems offers a very high level of security as standard and is designed with an anti-lifting device to prevent the removal of individual panels. With full aluminium reinforced interlock between each of the panels it is impossible to lever them apart.

The Grand Slider II incorporates a multi-point espag key-locking mechanism and full length 'keep' bar, which prevents the movement associated with inferior individual lock keeps over a period of time and complies with the requirements of the Association of British Insurers.

Track options

Depending on the configuration option of your set of doors the Grand Slider II sliding doors are available with a twin or triple track. Depending on the design of the external floor finish the tracks are designed to be able to be recessed into the ground to provide a virtually level threshold, with every track designed to incorporate drainage channels.

A cover plate can be fitted to cover redundant track sections adjacent to fixed panels, this helps to prevent dirt or debris from entering the track.

Weather seals

The Grand Slider II is a severe weather rated system (Category C, BS 6375-1:2009). Weathering rating varies according to configuration of the system, but these doors are tested to achieve up to: Class 7A, 300Pa water tightness, Class 3, 600Pa air tightness wind Class AE, 2400Pa wind loads.

Each panel is fully rebated, with concealed double nylon brush strips and fin seals surrounding the perimeter of each panel.

Operating system

The bottom frame of the Grand Slider II doors incorporated the operating mechanism of the system. This mechanism is made up of a double tandem, stainless steel sealed bearing carriage which is capped with polyamide to prevent any wear to the track. To ensure smooth operation we use additional carriages on each panel if the weight of the doors exceeds 200kg.

These carriages run on a stainless steel guide rail and we include a hard-wearing threshold cover plate to protect the track from damage. This heavy-duty operating system guarantees effortless and smooth operation that ensures the doors operate exactly as they are designed to time after time, year after year.

Glazing

The system is internally glazed for added security and can accommodate glazing of up to a sealed unit of 36mm.

Our standard double glazed unit comprises of 4mm or 6mm clear toughened glass with Low-E (low emissivity) to the inner pane x 16mm argon gas cavity x 6mm clear toughened glass to comply with building regulations for safety and thermal efficiency. The option to triple glaze the system is also available.

All units are BS kite marked, manufactured to BS EN 12600 and BS 5713:1979 standards.

The system when double glazed achieves an overall U-Value of 1.6W/m2K and when triple glazed achieves an overall U-Value of 1.4W/m2K.

Complementary systems

We understand that your sliding doors may not be the only glazing you are including as part of your project. That is why our range has been developed to include a number of complementary systems, from French doors, to aluminium windows, and from frameless rooflights to glass balustrades. Selecting all your products from one supplier makes your project management more straightforward and also means the finished products are all uniform in appearance.

U-Values and heat losses

A U-Value is a calculation of the amount of heat lost through a building material. The calculation of U-Values can be quite complex as it is measured as the amount of heat loss through a 1m2 of material for every degree difference in temperature either side of the material. It is indicated in units of watts per square metre per degree Kelvin or W/m2K. The simplest way to approach U-Values is the lower the U-Value the more thermally efficient a product is.

A U-Value of a door or window is calculated by working out by determining the U-Value of the frame and the area of the glass and is then quoted as an overall U-Value. Beware that some manufacturers may just be providing the U-Value of the glass alone which gives a false overall value. All of our systems have been thermally simulated in accordance with CE standards to BS EN ISO 10077.

Building Regulations approval will be required on all extensions and new builds to which we are able to provide CE data showing compliance. Any replacement works we are able to cover being a member of FENSA and a certificate would be provided on completion of our installation.

Double or triple glazing

Double glazing is a minimum requirement for external doors and windows. Our standard double glazed units consist of a soft-coat Low-E (low emissivity) pane and an argon gas filled cavity which provides a centre pane U-Value of 1.2W/m2K. Over the standard we can provide super insulated double glazed units providing a centre pane U-Value of 1.0W/m2K whilst providing solar control.

Triple glazing is becoming increasingly popular, especially in total new builds, as it provides the lowest U-Values possible and can be up to 40% more efficient than double glazing. Combining two panes of Low-E glass and two gas filled cavities glazing U-Values as low as 0.5W/m2K are possible with the added benefit of great sound reduction.

Solar control and the benefits of solar gain

With the standard glass specification retaining as much heat as possible you may wish to consider reducing the heat transfer from outside which is known as solar gain. Solar gain can make glass roofs, conservatories or south facing elevations quite uncomfortable in the height of summer months.

A solar control glass is a glass with a either a special coating or a body tint to reduce the amount of heat entering a building either by reflecting or absorbing heat. Using a solar control glass can reduce the need for air conditioning and blinds. Whilst the solar control glasses are great at reducing the heat they will also reduce light transmittance.

Building control often recognise the benefits of solar gain in modern buildings as large areas of glass will work as a source of free energy during cooler months and increased solar gains are recommended. The use of low-iron glass can increase the heat and light transmittance to provide further solar gains during the autumn and winter months. Many modern designs incorporate overhangs to cast shadows over glazing during the summer combatting the solar gains. Thus allowing solar gains as the sun gets lower in the sky later in the year reducing the need for heating.

Safety glass

When required we fit toughened glass to comply with Building Regulations Document N as an alternate method of compliance we are able to fit laminated glass. Both options have their pros and cons.

Toughened glass

Toughened glass has been heat tempered to increasing its strength over ordinary annealed glass by up to five times. Other than the strength the advantage of toughened glass is that should it break it would shatter into non-sharp pieces. It is also available with the widest variety of coatings and can be supplied in larger sheets than equivalent thickness laminated glass.

When the glass is toughened it can suffer from some visual distortion making, meaning the face of the glass is not perfectly flat distorting some reflections.

Laminated glass

Laminated glass is manufactured by bonding two panes of annealed glass with a clear plastic interlayer. The benefit of laminated glass is that if it’s broken the glass will crack rather than shattering, improving security. In addition, laminated glass reduces bleaching of carpets, curtains and furniture by filtering UV rays that would usually penetrate the glass.

The drawback of laminated glass is that extreme heat or cold can cause invisible defects in the glass to form a crack due to the two panes expanding and contracting independently. As the laminated glass is not toughened is does not suffer from the visual distortion that can occur to toughened glass during the toughening process.

Custom designs

As well as offering full height clear glass we can also provide a more traditional style of glazing by incorporating glazing bars, Georgian grids or lead work. Please contact us for further information.

Cat flaps

Often neglected when planning your new build or extension is where a suitable space may be for your feline friend, we have the ideal solution. It is possible to have a cat flap fitted into a glazed panel by cutting a circular hole into the toughened glass unit for you to fit an in-glazed cat flap.
