Innovative single track slide & stack door system
Subject to a maximum panel weight limit of 100kg, the Monotrack can be manufactured up to 1,500mm wide and 2,800mm tall.
The end panel can be fixed with all other panels sliding behind or it is possible to have the panels slide behind a single opening door or behind a wall or fixed screen so that panels slide completely out of sight into a pocket, providing complete opening.
Each panel is designed to slide easily and around corners from 90° to 270° into a remote stacking area. Each panel slides individually on the same track and interlocks with its neighbour when closed.
The Monotrack incorporates a multi-point espag key-locking mechanism in the end door, with each individual sliding door interlocking with its neighbour to create a continuous system when closed. With no hinges or handles on intermediate doors and with the doors running on a single track there is no external hardware required.
The system is internally glazed for added security and complies with the requirements of the Association of British Insurers. The system can be supplied to BS EN 1627 RC2 enhanced security accreditation.
The Monotrack features a unique extending gasket when the doors are closed which is extended at the top and bottom of the door by turning a handle on the inside to create a significant weather seal. The Monotrack is a severe weather rated system to EN1026 Class 4 | Air Permiability, EN1027 Class E750 | Water Tightness, and EN12211 Class C2/B2 | Resistance to Wind Load.
The operating mechanism consists of a stainless steel sealed bearing bottom-running carriage coated with polyamide preventing any wear to the track. It runs on an aluminium guide rail and includes the option to add base plate wings to the track, enabling you to hide the flooring underneath these plates on both the inside and outside - creating a flush finish.
The system is available as standard or polyester powder coated in pure white RAL 9010 semi-gloss, white RAL 9016 semi-gloss, anthracite grey RAL 7016 semi gloss, light grey RAL 7035 semi-gloss, white aluminium RAL 9006 semi-gloss, grey aluminium RAL 9007 and Dark Grey DB703 texture. Alternatively for an additional fee the systems can be polyester powder coated to any of over 200 stocked RAL colour. In addition you can specify whether a matt, semi-gloss or full-gloss level of paint finish is required.
Door furniture comes in coloured to match the frame as standard. We can also offer stainless steel feature handles for a more contemporary look.
Trickle vents with an airflow equivalent to 2,500mm2 or 5,000mm2 can also be incorporated with the addition of a 20mm add-on head profile; these also can be colour coded to suit.
We also provide complementary single doors, French doors, tilt and turn windows and fixed glazed screens, to achieve an aesthetically uniform appearance throughout.
The system is internally glazed for added security and can accommodate glazing of up to a sealed unit of 62mm.
Our standard double glazed 28mm 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.
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.
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 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.
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.
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.
