ROOF WINDOWS HELP CREATE QUIETER HOMES


The best house developers aim to create quality homes that are quiet, as well as secure and energy-effi cient. Success in this area starts with the roof windows, as Altaterra’s Mhairi McDougall explains.


T


here are various elements that reduce the possibility of noise reduction when selecting


roof windows.


CHOOSE TRIPLE GLAZING Single glazing, once the only choice for windows, is now rarely used in developments due to the below-par insulation, noise reduction and energy effi ciency it offers. ouble glaing is clearly a better choice but professional window installers always recommend housebuilders choose triple glazing. A more expensive option, it nevertheless elevates the quality of any home for a host of reasons.


The three panes, each with a layer of gas between, means triple glazed windows are more insulative than double glazed. It’s harder for heat to escape in winter, and for heat to enter in summer and means lower heating bills. This also counts for glazed roof windows in attic rooms. Particularly helpful for houses near busy roads, three panes offer greater noise reduction, making it more diffi cult for sound to pass through the glass when the windows are closed. The best windows can lead to 50% more noise reduction than standard windows. he improved thermal effi ciency of triple glazed windows reduces the risk


of condensation. By helping to keep the internal temperature up, moisture in the air is less likely to condense on the glass.


SECURE DESIGN


Look out for features to make a secure and quieter design: laminated internal panes, toughened external panes, strong and solid locks that leave no gaps when closed, reinforced hinges and a glued pane which means would-be intruders can’t remove the glass.


SUPERIOR GLASS


Always choose laminated glazing which is especially effective when paired with a toughened external pane.
