Seeking to conserve cash but get the acoustic performance? What can be done to make triple glazed sash windows efficient in an initial box frame?

One of the most significant problems we confront with triple glazed sash windows is discovering the depth in a standard frame for the triple glazed system itself. For triple glazed sash windows to be effective you need a great size cavity( air gap between the panes of glass, a minimum of 8mm but the more the much better) in the first place. this means that if you wish to set up triple glazed sash windows in to the original frame you really should have a minimum of 40mm depth, some original frames have this and some have not. Don’t worry if not, there are still lots of choices and workarounds to keep the rates practical. The other manner in which we can deal with triple glazing is by over making the depth of the sash and then rebating the face edge so that we can get the general depth required, this isn’t a sash repair work, this is performed in our workshop at point of manufacture. What this indicates is successfully cutting the corner out of the sash which permits the sash to pass the edge of the frame.

What is the spec of triple glazed sash windows?
Many frequently triple glazed units for sash windows are formed with 6.8 mm or 8.8 mm acoustic laminate glass as a base for the soundproofing, a good sized air gap( as we discussed 8mm as a minimum but preferably bigger), and 4mm float glass. This is the base for a high quality noise evidence system on a sash window and if you would really like to understand your glazing then please check the article highlighted.

Having different thickness glasses stop different noise frequencies which assists to increase the performance of your triple glazed unit. By the way, the latest concept to increase noise reduction is two panes of acoustic laminate instead of one with a 4mm float pane of glass But this can be a little excessive in a sash window because of the large weight of the window that needs to be reversed. That said, the sash can always be put on spiral balances to decrease the expense of system however it’s popular that this system is as long lasting or quality is a traditional sash cord and weight. Sash cords can actually be replaced by the house owner, whereas spiral balances are even more tough and need a specialist.

Do triple glazed sash windows look any different to initial single glazed sash?

The excellent feature of our triple glazed sash windows is that over the years we’ve managed to establish them so they almost appear like single glazing front on. If you’re to take a look at are triple glazed sash windows from straight you would hard-pressed to tell the difference between them and single glazing. The greatest hand out, is the truth that there’s a reflection from the several panes of glass, otherwise you would not really understand that these have actually got a triple glazed system inside, much in the same way as we manufacture double glazed windows.

Triple glazed sash windows set up into the initial frame.
Above is a photo of a triple glazed sash window that’s been set up into the original frame. This has actually undergone the treatment discussed above of having the face edge of the top sash rebated to allow for a thicker sash that the frame could usually carry, this way we have the ability to increase the size of the of the triple glazed system and the outcome was impressive, particularly because this home was over a flight path. Whilst it didn’t totally get rid of the noise of an aeroplane, it actually made a significant distinction and dulled the noise to the point the noise remained in the background. You won’t cut noise to no due to the fact that as efficient as the glazing is, the sound can still come through walls and roofing too but it’ll definitely improve things substantially.

How much do triple glazed sash windows cost?
Normally triple glazed sash windows cost around ₤ 1300- ₤ 1500 when set up into the original box frame. This represents around 35% more than double glazed sash windows. This expense is just a case of the glass being more costly along with there being an additional counterbalance expense. If you think about the 8.8 mm glass is double the weight of 4mm glass, it substantially increases the amount of counterbalance lead required to make the window sat tight when you open it. If you totally replace the sash window consisting of package frame too then the cost will begin with anywhere from ₤ 2500 pounds per sash window.

There is a fringe benefit to whole replacement, and that is that the noise reduction is a little much better due to the fact that where we manufacture a perfectly square brand-new frame, the sash seals to the frame a little bit much better considering that bit additional performance. Ultimately, triple glazed sash windows into the original frame is better value for money however not quite as efficient as a totally new triple glazed sash window. Pound for pound though, triple glazing into the initial frame is far better value for cash when considering the decibel decrease per pound invested.

If you’re truly battling with sound pollution and in particular situations I’m aware of the situation where clients actually can’t even oversleep their own house in the evening, and you desire the absolute highest quality sound reduction possible then that would be to have two panes of acoustic laminated put together as a quadruple glazed system. This seriously cut the amount of noise pollution but the disadvantage of course is the cost. This lemon glazing can set you back from anywhere from ₤ 3500 per window if completely changed.

There’s little point in using the initial frame in a circumstance where you’re going for Absolute noise reduction due to the fact that you can’t get the perimeter seal to be as perfect as a new There’s little point in using the original frame in a situation where you’re going for outright sound reduction since you can’t get the perimeter seal to be as perfect as a new box frame. If you understand how acoustics works, then you’ll realise it may be worth actually sealing the window closed.

However one should consider that there requires to be a fire exit along with conforming to all guidelines and we can not make an illegal set up. If you have more than one window in your room then it may well deserve sealing one shut so that you can definitely maximise the sound reduction and have no spaces around the glazing. Remarkably the spaces around glazing contribute to a substantial percentage of all of the sound pollution that actually survives the window. That’s why setting up a comprehensive draught proofing system is so crucial in combination with this acoustic glazing. As soon as you’ve installed this triple stroke quadruple glazing, the next thing to do is to set up a secondary glazed sash window over the top of this. This definitely guarantees that you minimise the quantity sound coming through the window totally. All that will be left, is the sound that comes through the walls and ceiling.
