Aluminium Casement

Insulated, three-chamber thermally broken profile designed for display windows, windows and doors.

Application of polyamide and fiber glass supported 24mm thermal break enhances durability and thermal insulation of the profile. Heat transfer coefficient for the Imperial profile is Uf = 1,9 W/m2*K.
Modern design of the window

Modern, metallic material supported by almost limitless palette of RAL colours of smooth or structural finish and wide choice of additional profiles make aluminium doors, windows and large-sized glass and aluminium segments a modern architectural motive.
Deep aluminum profiles

Imperial are 65mm installation depth profiles.This is 20mm deeper than industry standard ensuring the profile provides perfect statics giving giving architects and constructors more flexibility for any project design and application. The Imperial system allows designing large-size constructions.
Single glass panes or glazing units of 4 to 51mm are mounted and sealed in the rebates of the sashes with the usage of glazing beads from the aluminum profiles and durable EPDM rubber seals.

The powder coating of the aluminium ensures that your windows can withstand the toughest wind conditions. Nevertheless, we advise you to take good care of them. In that way, they will remain in top condition!


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.


Environment & Energy-efficient

During the construction or renovation of a house, it is important to take the insulation values into account. The U-value is especially important for windows and doors.?  

The lower the U-value, the better the insulation value of your window.  
Aliplast Imperial meet the high requirements with respect to insulation values. This makes your home extremely energy efficient. For an optimal match, take the U-values of both the glass as well as the aluminium window into consideration.



A cosy, warm and safe feeling is paramount in your home. To guarantee this sense of security, you can opt for additional burglary protection for your windows and doors.
Naturally, every window offers a basic level of security and, moreover, aluminium is a very strong and almost unbreakable material. Nevertheless, there are additional options available to make your home even more secure. Aliplast ensures that all its product ranges are tested for burglary protection (in accordance with both European . ?
