Due to technically advanced production in shape and dimensions ALU Windows can be adapted to any style of construction: from classic, rustic, all the way to newer, minimalist styles of construction. In addition, due to its properties and elegant appearance aluminium is one of the most suitable materials for renovation of cultural and historical monuments..

ALU windows boast excellent thermal and sound insulation. They are available with both double and triple glazing from 22 to 50 mm thick glass.

In the company SIMER PLUS we use carefully selected series of profiles of different suppliers. for the production of quality windows. A large selection of profiles allows the production of various construction typologies suitable for all types and aesthetic styles of residential, industrial and commercial buildings. It also satisfies different styles of modern architecture.


Manufacturer of ALUK profiling

This series of window profiles has xcellent characteristics. Despite its small dimensions and shapes, it is suitable for renovating and replacing old builders’ joinery.

Depth of ALU window profiles 67IW: 67 mm, sash depth: 77 mm.

The ALU window system enables better static sealingand thermal-acoustic characteristics. ALU windows include specially designed profiles for windows and doors of all dimensions, ideal for use in business premises and residential buildings.

Shape and comfort:
Alu windows with special thermal bridges made of polyamide (28.5 mm), which increase stability and strength.
To ensure a maximum thermal conductivity Uf of 1.7 W / m2K.
With glazing Ug = 0.6 also up to 1.1 W / m2K.

Acoustic parameters: Rw = 47 dB
Air permeability:Class 4
Waterproof: E1200
Wind resistance: C5

Thanks to special ALU profiles and fittings, our windows also provide protection against burglary.

Manufacturer of ALUK profiling
ALU windows are designed to satisfy the increasingly demanding marketin terms of features and comfort. They are suitable for new constructions as well as for renovation and restoration of old ones. They satisfy the needs of demanding customers in terms of design, details and performance because they maintain the basic characteristics of ALU windows.

Shape and comfort:
The new series of ALU windows 77IW represents a system with increased thermal conductance, due to the use of new 39mm reinforced polyamide strips, and additional insulating inserts.

Stability, thickness, safety:
The selected solution enables the reduction of air movement by convection inside the profiles, which enables the system excellent and reliable thermal-acoustic properties.

Uf= 1,1 W/m2K
Uw = 0.96 W / m2K for a window measuring 1230 × 1480 mm with glazing Ug = 0.6 W / m2K
A system with a frame depth of 77 mm and a sash depth of 87 mm offers the best solution at the moment.


The 77IS series of windows features high degree of thermal insulation, obtained by using improved 39 mm hollow polyamide rods and the addition of special insulating tapes.
Such a solution reduces convective movement in the profile cavity, thus providing exceptional therma, and sound insulation and satisfyingeven the most demanding customers.

PROFILE WIDTH: 77 mm – 87 mm
FEASIBLE TYPOLOGIES: Windows and doors
THERMAL CONDUCTANCE Uw = 0.9 to 1.6 W / m2K

FEASIBLE TYPOLOGIES: Windows and doors

The series is based on a very stable 5-chamber profile with a depth of 80 mm and is also suitable for large openings. The system provides fire resistance level of up to 60 minuteswhen using fire resistant glass.

In connection with additional elements for fittings, we can manufacture customized multi-purpose doors designed to meet additional building safety and automation requirements For example: anti-burglary protection RC 2, panic functions, access control and reduction of sound conductivity up to 42 dB.

Extensive equipment optimization allows the fabricationof even more effective products. It completes a wide range of applications and designs by using panels, door panels and fixed glazing.
