    Trickle vents - yes or no?

    Trickle vents - yes or no? 14th Jun 16 at 11:16 PM
    Should've asked this sooner really. We're going to have new windows installed on the front downstairs of the house real soon. I have asked for trickle vents, but now i'm thinking against it.

    The only one we have a trickle vent in in the whole house is the patio doors at the rear which we constantly leave open throughout the year.
    We have tried with it shut & it's fine in summer but in winter if you leave it shut there's so much condensation on the glass & frame in a morning. If it's open then sure there's condensation but not nearly as much.

    This was my thinking for the front of the house - leave the vents open & less condensation forming. Also safer than leaving the window slightly open on the 'night lock'. Not that we live in an unsafe area, but it only takes 1 idiot.

    I personally think they LOOK horrendous, but it was more the purpose it's serving that i decided to go ahead with them.

    But i've read of them whistling under heavy wind, even when closed.


    Just in general now, i'm wondering if i should bother with them.

    A little feedback would be great before it's too late to change my mind

    Oh dear this is all getting contentious! To add a few pointers leveller2911 does not like them and says they are no longer compulsory. I understand this view but my earlier point was about the background/history. What leveller2911 overlooks is when windows started having them fitted in the 1980s the windows were simple timber construction without multi point locking. Yes night latches were fitted but these were rudimentary.

    To quote Buildings regulations Departments is unfair. These departments and officials are just concerned with the law and not good practice, nor workmanship issues, nor design, nor project management. so a bit of a red herring here.

    SuzieSue is correct in saying they perform a function. This is because of security if a window is set on night latch, but also because of simple physics. A night latch setting gives a far greater area of gap - it is all around a side opening sash. Hence drafts, and noise can be a problem, not experienced with a trickle vent.

    As for JAS saying he has a night latch setting to relieve condensation - this will only work if this is always open, and this raises the issue of security and cold drafts. Entirely up to JAS here, but knowing there is a damp issue I maintain the decision to delete the trickle vents from the order was foolish, or naive, or both.

    I agree. Choosing to not have trickle vents when there is a preexisting condensation issue is madness.

    I used to live in a flat with major moisture issues, it was awful. It was always stuffy, and we were always ill. I'll never put myself and family in that kind of environment again.

    Well I enquiries as to whether it's too late to change them (include them again)
    & apparently it is as they're 'in production' (which takes 2.5 week)

    No money has been handed over yet.

    I bet alterations would soon happen if I said cancel the whole order.

    I like the thanks button, but ,please, an I agree button.

    Will the grammar and spelling police respect I do make grammatical errors, and have carp spelling, no need to remind me.

    Always expect the unexpectedand then you won't be dissapointed

    To be fair I don't think anyone was suggesting trickle vents would 'fix' the damp. They'd help with the condensation though.

    Only time will tell if I made a mistake or not. If I did then I allowed myself to be swayed by some people on the internet which again .... Is my own fault.

    Good quality windows are available in three days, and anything taking 2.5 weeks suggests a low quality, minor, manufacturer. This is concerning, as is the response to fitting trickle vents.

    Any reputable manufacturer would accept the change to the order. Here the manufacturer cuts out a slot as the window is manufactured - it is basically using an ordinary router, and the vent is a bought in simple, low cost, low quality, clip on piece. The procedure is quick, cheap, childs play.

    In defence of the window company, they supplied the default position of fitting the vents and it was you who did not want them. Your early posts referred to them being ugly.

    The window company are probably peed off with you, but you are again again accepting BS being fed to you. Only you can answer why this continues to happen to you and what is the best way forward.

    Trickle vents serve a purpose that can be achieved in other ways but those ways have disadvantages over a simple vent?,
    Advantages of vents (ventilation aside) are more beneficial to client e.g. security, noise, not requiring power, potentially less insects, bugs, maintenance, ease of use irrespective of functional operation of window etc, None being beneficial to manufacture whom adding vent can require more work, trickier manufacturing etc so little incentive for manufacture and could be why some don't sing there praise and why there was such a backlash when they were compulsory for me the advantages for client/user are clear....

    I just have a question to the chap who makes the windows who has been replying on here....

    These guys telling me it's too late to put in this change - what is your take on that?

    I'm not pretending to know anything about making windows but i'm guessing it's get some glass, cut it to size, fit it in the frame (which also has to be made to size - not the lengthiest of jobs i'd imagine) & that's basically it.

    I'm guessing (again) the 2.5 week is due to their workload. So if it can't be done NOW then that'd be only 1 week, not 2.5 week.


    At the very least i'd have thought that they could've said - we'll check if it's too late or not rather than "well the guys trotted off with his measurements so it's too late for you".

    And even if it has all been put together, don't they just cut in a couple holes & stick a plastic vent over them anyway?? If that's the case then it could be done at any time, start or end.

    trickle vents
    All new windows must be A rated, that means 5 air tight cavities through the section of the window frame, 4 of these must be no more than 6mm wide to prevent thermal currant in the void. If trickle vents are fitted, the frame needs to be drilled therefore drilling through the cavities, therefore the frames are no longer A rated as it they do not have air tight compartments,

    It depends on the property and how it is used (eg do the occupants open windows for a while every day all year round). In some properties and with some occupants you will get condensation and mould if you do not have trickle vents. In others, it doesn't matter. There is no correct answer for all properties.
