70mm Thermally Efficient Five chamber profile

IDEAL 4000 boasts five chambers (front to back) at the core of its design philosophy. Having two chambers either side of the reinforcement chamber greatly reduces thermal bridging and provides a superb thermal insulation performance.

Acoustic insulation or noise reduction is also much improved so windows manufactured from IDEAL 4000 provide the householder with a greater level of all round comfort and well being.The five chamber construction and resulting thermal performance means that IDEAL 4000 is well prepared for any changes to specifications or building regulations calling for enhanced thermal efficiency.


German design & technology.

1. Matching bead and profile design

The bead shape mirrors the shape of the upstand to the glazing rebate to provide a beautiful balanced appearance with identical sightlines. The finished window looks identical viewed from inside or outside; simply stunning! While 28mm high performance double glazed sealed units have become the performance standard in the domestic sector, IDEAL 4000 recognises the need for the option of 24mm glazing depth to meet a wider range of window and door specifications for other market sectors. Glazing beads for both 28mm and 24mm sealed units both offer a squareline appearance that perfectly complements the profile detail. Triple glazing can easily be produced utilizing our 36 and 40 mm glazing beads.

2. Squareline contemporary profiles

IDEAL 4000’s cleverly designed sculptured shape makes for simply stunning windows and doors. Beautiful both inside and out with a design focused on symmetry, IDEAL 4000 windows and doors are perfect for replacing the replacements; an important development for the future of the industry. IDEAL 4000 windows and doors are eminently desirable for the end user. IDEAL 4000 is as easy to fabricate as it is stunning to look at. The positive stops at either extreme of the sculptured shape give defined datum points for modern window fabrication machinery and also make fabrication easier in more basic fabrication environments. IDEAL 4000 combines stunning good looks with ease of fabrication.

3. Single leg glazing bead

IDEAL 4000 employs a secure single leg ‘knock-in’ or J-bead design. The single leg bead makes for faster, easier installation and provides the cleanest glazing platform. Installers love the way the single leg bead locates and the single leg format affords both stability and security while also easily accommodating normal glazing tolerances. aluplast’ secure bead system passes Secure by Design and PAS24 with ease. Choose from either black or papyrus grey gasket

4. Co-extruded gaskets

IDEAL 4000’s co-extruded gaskets eliminate the need for the time consuming application of weather seals and gaskets to frames and sashes following the welding process as part of fabrication. The time saved will provide an increase in fabrication efficiency. Using IDEAL 4000 with its co-extruded gaskets will also enable the fabricator to reduce stockholding. IDEAL 4000 gaskets provide outstanding weather performance and complement the profiles’ elegant sightlines. Co-extruded gaskets eliminate “the shrinking back” effect typical of old gasket systems and therefore prevent any gaps in corners. IDEAL 4000 windows and doors are also easier to fit and come in two options of ether black or papyrus grey gasket.

A profile depth of 70mm also allows for greater flexibility with regard to glazing thickness. IDEAL 4000 permits glazing of 28mm or 24mm double and 36mm or 40mm triple glazed high performance units with the same consummate ease.

The profile design incorporates lugs to locate the reinforcement profiles. Orientation options are provided for steel reinforcements that allow optimum selection for economic production and facilitate insertion of reinforcement profiles prior to welding of the PVC-U sections.

The Alu Skin IDEAL 4000 system is available in all RAL colours.


Glass Options

Nobody takes glazing more seriously than Windows Doors London. That’s why we offer multiple high-performance glass options that will suit … Client


Low Emission Glass

Thermal protection is the basic task of glazing units designed for windows. Thanks to our partnership with suppliers, resulting in development of new glass coats, PRESS GLASS is able to offer glass panes with even lower heat transfer coefficient Ug= 0,4 W/m2K. This value is close to the value of heat transfer coefficient of walls. Cold feet near the window are in the past.


Warm Edges Glazed Units

It should be emphasised that the actual effect of a thermal bridge on the edges of glass units mounted in windows depends on the type of spacer bar, heat insulation of the central part of the glass unit and the depth of the pane seating in profile and the coefficient of heat penetration Uf of profile. Together with the increase in seating depth of the pane the proportion of heat loss of windows through the edge is reduced and minimises the possibility of the occurrence of water vapour.


Safety & Security Glass

Safety glass protects against injury at breakage, making it less possible to break the glass when lamming a door or window.
Types of safety glass:

  • tempered,
  • laminated,
  • wire mesh reinforced patterned,
  • wire mesh reinforced polished


Solar Control Glass

It offers quality and beauty, helps save energy, and allows for easy assembly. Among its various qualities, there is one which is especially useful for offices and public facilities, namely solar protection. Solar control glass adds character to a building and reduces undesirable heating of the elevation regarding a type of coating.


Acoustic Glazed Units

Our subjective perception of noise is subject to the following principle: if the level of noise in a room is reduced by 10 decibels with relation to that outside, we get the impression that it is reduced by half. Noise protection must be applied everywhere where noise cannot be completely eliminated. In such applications we are faced with acoustic double glazed units.


Fire Resistant Glass

We offer a wide range of fire-resistant glass options with varying levels of protection to suit your needs. Protection levels are measured in defined time periods (30, 60, 90, 120 and 180 minutes) and in terms of either integrity and insulation or integrity only, as designated by the European Standards.


Ornamental Glass

In multiple design solutions it is required that glass panes are perfectly transparent and ensure intimacy at the same time. Right selection of ornamental structure of glass can enhance or aggravate transparency and image deformation properties. Windows Doors London offers tens of types of ornamental glass.
