Sliding sash cords and weights windows

The sliding sash cords and weights window uses pulleys and weights as the lift system. It is primarily used when build circumstances dictate or when conservation requirements are a consideration, ensuring the character and charm of the building are maintained whilst incorporating modern technologies, security, and performance.

Sliding sash spiral balance windows

The Sliding Sash Spiral Balance window or tensioned spring provides the mechanism of lift to the system. Predominantly used in new build construction, it offers a cost-effective solution to this style whilst retaining all the unique features of a sash window.

Flush casement windows

Casement windows offer a simple and elegant look. Specifically designed to replicate a period window whilst incorporating the latest modern operation and security features. Often referred to as a conservation window, the design is characterised by a sash that sits within the frame to create a flush finish externally, the perfect choice for listed properties.

We make them by hand from softwood, hardwood or structural oak. We will ensure that your new casement windows match the windows currently installed on your property or your personal preferences. This can be achieved through a wide range of design, placement, glazing, wood and painting options that we will be happy to discuss with you. The casement windows we produce fit well for new-builds, restoration projects, and heritage buildings.

What materials do we use?

Pine

Meranti

This exotic hardwood comes from Indonesia, and its main feature is its extremely high resistance to atmospheric conditions. Windows manufactured from meranti are not only very durable but warm and quiet. Hardwood density strongly depends on the type and reaches between 300 kg/m3 to 1050 kg/m3.

In the manufacturing process of windows and doors, the most commonly used is meranti, with a density above 450kg/m3. It is recommended to use meranti in places exposed to moisture. This provides stability to the finished product.

Glass units & types of panes

Float Glass Manufacturing. Tempered double glazed sealed units

Single-chamber glass pane

Standard single-chamber insulating glass unit consisting of two panes of glass. In the space between the panes, there is an argon gas, which further reduces the heat transfer coefficient U.

Specification:

Two panes, one of which is coated with a low-carbon coating;
Standard construction of a single-chamber pane – 4/16/4;
Possibility of building packages of different widths;
Aluminium distance frames as standard;
As standard, filled with argon;
Possibility of using warm distance frames;
Possibility of filling the panes with krypton;

Two-chamber glass pane

A solution that increases the thermal parameters of the window and thus provides much greater thermal comfort than single-chamber windows. Manufactured using a warm distance spacer, they can be successfully used in energy-efficient constructions. Thermal transmittance coefficient U from 0.4 to 0.8 W/m2K.

Specification:

Three panes, one of which is coated with a low-carbon coating; standard construction of a double-chamber pane – 4/12/4/12/4;
Possibility of building packages of different widths;
Aluminium distance spacers as standard;
Filled with argon;

Possibility of filling the panes with krypton

Sound-absorbing glass pane

Laminated glass with special acoustic foil is placed between the glass panes. Glazing increases acoustic comfort in the interior, providing an exceptional level of soundproofing. Acoustic glazing can be used in both residential and public buildings.

Specification:

External side: Laminate made of float glass and sound-absorbing foil;
Inner side: Float glass with a low emission coating;
Aluminium distance frame;
Glass filled with argon;

Safety glass pane

Thanks to its unique construction, the safety glass is characterised by increased resistance to breaking or shattering. In the event of breakage, the glass remains attached to the film, making it unlikely that people will be injured. The film makes it difficult to break through the glass.

Specification:

External side: Two panes of float glass joined by a 1 mm thick film;
Inner side: A sheet of float glass;
Aluminium distance frame;
Argon-filled glass;

Sun protection glass pane

The sun protection glazing on the outside is covered with a special layer of film, which reduces the flow of sunlight entering the building. The glass reflects and absorbs heat and filters light to reduce glare. Sun protection glass can reduce the costs associated with using air conditioners in the summer and reduce the use of sun shades.

Specification:

High light transmission;
Limited amount of heat entering the interior by more than 30% compared to the traditional one;
High-efficiency glazing units;
Very good ug value of 1.1 w/m2k;
Neutral appearance of objects viewed through the glass and in reflection;

Anti-burglary glass pane

Anti-burglary glass effectively reduces the risk of burglary or theft. We recommend glazing with resistance class P2 (two sheets of glass and two layers of film) and P4 (two sheets of glass and four layers of film). Thanks to the laminate, anti-burglary glazing provides security, dampens sound waves, and protects against excessive solar radiation.

Specification:

External side: Laminate made of glass and PVB film (2 or 4 layers of film and glass);
Inner side: Float glass;
Aluminium distance frame;
Glass chamber filled with argon;
