There are 3 ways you can improve the sound insulation of your existing or new windows:
1: Ensure that any air gaps around the perimeter of the window openings are sealed
This can be easily achieved by having our Sashcure system installed. If you can can imagine that a typical Sash window may have around 3mm of clearance around its running edges, this area can add up to the size of house brick on an average size window! It is also a good idea to ensure that the perimeter of the outer frame or sash box is adequately sealed. A sash box is hollow and can amplify noise similar to an acoustic guitar, with the pulley holes acting as the sound holes. Casement window sashes or doors are often warped and twisted so can fair just as badly.
2: Glaze your new or existing windows with a sound insulating glass such as Pilkington Optifon TM
This can be single glazed or incorporated into a double glazed Sealed unit. We use a 6.8 mm laminated glass that has a special transparent membrane sandwiched between two sheets of 3mm glass. This membrane helps absorb certain sound frequencies; greatly improving the overall sound insulation. We can incorporate this glass into our Slenderglaze System.
3: Secondary glazing
Secondary glazing is fitted in front of the main window and can be supplied in various formats for different types of windows, i.e Sliding sash, with tilt back facility for cleaning, horizontal sliding, hinged or fixed panel Secondary glazing has good sound reducing qualities because of the distance between between the glass in the primary window and the secondary window (150mm is the optimum). The advantage of secondary glazing is it can be installed without altering the original window and can be cost effective compared to replacement. We can offer the right solution for your situation and will provide the most discreet and best quality units available.
We also manufacture shutters that can be fitted with sound absorbing panelling
