CNC Laser Cutting
Laser cutting is a fabrication process that uses a thin, intensely focused stream of light to cut through a range of different materials, including plastics and acrylics. Read more
Diamond & Flame polishing
Edge polishing is a fabrication process that polishes the edges of acrylic panels, removes any cutting marks, and achieves a smooth, glossy finish. Read more
Rotary & Laser Engraving
Laser engraving is a fabrication process that uses a laser beam to physically remove the surface of a material to create an indentation that is noticeable to both the eye and touch. Read more
Line bending is a process that’s used to make precise folds in plastic and acrylic components. Our line bending fabrication service allows us to bend plastic and acrylic sheets along a defined ‘line’ – without any need for gluing or joining. Read more

Unlike double glazing, which involves fitting completely new units (with all the associated expense and disruption), fitting secondary glazing is a fast and simple DIY process which helps to reduce heat loss in your home. You simply attach the acrylic panel to your existing windows or window frame using magnetic adhesive tape.
- Excellent optical clarity
- Light weight
- Excellent insulating material
- DIY installation
- Cut to size
- Reduced sound levels
High optical clarity
Acrylic sheet benefits from excellent optical clarity, it's as clear as glass so lets light through while keeping the cold out.
Once installed and supported by the magnetic tape, acrylic glazing panels can be easily removed and stored when not required.
Acrylic performs well as an insulating material, providing superior insulation to a sheet of glass of the same thickness, in addition to being cheaper and easier to install and maintain. The thermal conductitity of a material is measured by a property called the 'K value' which refers to the ability of a material to conduct heat. A low K-value is advantageous for insulating materials, as this means heat energy cannot easily pass through. Traditional single pane glass has an average K value of 0.96 whereas our Acrylic and Polycarbonate sheets have a K value between 0.19 and 0.21 which demonstrates why these materials provide superior insulation, in addition to being cheaper and easier to install and maintain.
Fitting secondary glazing is a fast and simple DIY process. You simply attach the acrylic panels to your existing windows or window frames using a magnetic adhesive tape kit. The kit, which must be purchased seperately (see Magnetic & Steel Tape) has two parts, a steel tape which is applied directly to your window or window frame, and a magnetic tape which is applied to the clear acrylic panel. You can alternatively choose to have holes drilled in the panel, however you will need to ensure that a foam tape is also fitted to all edges of the panel to ensure there are no gaps that allow the heat to escape.
Please note: If you are fitting panels larger than 1.4m x 1m you must use the 19mm wide tape due to the panel being too heavy for the 12.7mm wide tape.
In addition to reducing heat loss acrylic secondary glazing also reduces noise levels. Acrylic sheet offers sound loss characteristics comparable to glass.
Acrylic secondary glazing is ideal for all homes that have single glazing, period properties with sash windows, buildings where renovations are not possible, and schools, offices and large areas that are difficult to heat adequately during the colder months.
Cut to size
Ordering acrylic glazing panels is easy, simply measure up and order the exact sizes required ready for fitting. Ordering cut to size is not only convenient but reduces waste material keeping costs down.
Please note: This product does not include the magnetic tape which must be purchased seperately.
