Tubeway supply a comprehensive choice of cost effective seasonal glazing products, designed for easy installation by any DIY enthusiast, and not requiring any special tools to fit. Each product allows you to insulate your windows against heat loss and draughts, as well as noise, and most can be used with either plastic glazing sheet or glass. All of our secondary glazing systems are suitable for removal in warmer weather, and re-installation of the glazed panels when next required, although the Trackglaze system allows simple slide opening for ventilation without panel removal.

For comprehensive information on heat retention, noise reduction, condensation and comparitive costs of glazing systems, click through to our Secondary Glazing Benefits page. There is also a gallery here showing examples of Secondary Glazing installations by our customers.

Glass or Plastic glazing?

Weight can be a factor in your choice. To help you calculate the approximate weight for windows of any size, use this formula:
Height (m) x Width (m) x Thickness (mm) x Specific Gravity = Weight (kg)
Specific Gravity is 2.58 for Glass, 1.19 for Acrylic sheet and 1.22 for Polycarbonate sheet.
Therefore approx weight of a metre square of 4mm Glass is 10.32kg, and of 4mm Acrylic is 4.76kg
