As an antidote to the Brexit discussion I intend to beg comment on a
series of queries related to an about to start extension/major refurb. of an existing timber frame chalet bungalow. Not having Tim Ws stamina the bulk of the structural/roofing work will be done by a local building company. Q1. The existing windows are narrow spacing double glazed in brown painted pine. Two or three panels are blown and need renewing anyway. My first thought was to strip out the glass and strip off the paint. Re-paint in white and fit modern argon filled panels. However, the glazing rebate is much too narrow to use 4:16:4 units. Six new windows are required for the alterations so current thinking is to go for new throughout. First estimate for 12 windows and two doors came in at 18K fitted. This afternoon was spent trawling round the local showrooms. I'm not much wiser:-( The much vaunted narrow mullion aluminium does not seem to exist. By the time they have put in the plastic thermal break and endless folds for strength and appearance they are as fat as uPVC. Also, what happened to window hinges and stays? They all seem to use a fancy sliding meccano mechanism which relies on a tiny strip of plastic in a groove to retain the window against a stiff breeze. And why do doors supplied by such outlets have such flimsy threshold strips? Also, also my wife who is somewhat challenged vertically came back from a jaunt to the Cotswolds determined that fanlights are out! (hard to clean and hard to reach). The new *in* is top hung bottom latched full length openers. Thoughts please. Does uPVC really stay clean and shiny for 20 years? Are these fancy sliding fixings reliable? Can a bottom opening style meet the fire escape regulations. -- Tim Lamb |

It gets depressing as it drags out. Our slowness was due to lack of dosh. That problem has reduced and I have happily got some help on certain areas, whilst being lucky enough to maintain the original design ideas. Q1.

If you look at windowsanddoors.co.uk you will get an idea of the cost of the units - at least for uPVC Also, what happened to window hinges and stays? They all seem to use a fancy sliding meccano mechanism which relies on a tiny strip of plastic in a groove to retain the window against a stiff breeze. I know what you mean. Not as bad as they look - and hinge bolts mitigate. I recommend you specify egress (corner swinging) hinges - they always seem to default to "easy clean" which I hate. And why do doors supplied by such outlets have such flimsy threshold strips? You can get uPVC with a low profile ali threshold - I have one. And you can bond or seal that down whereby it is pretty solid. Also, also my wife who is somewhat challenged vertically came back from a jaunt to the Cotswolds determined that fanlights are out! (hard to clean and hard to reach). The new *in* is top hung bottom latched full length openers. Thoughts please. Does uPVC really stay clean and shiny for 20 years? Non white might. Are these fancy sliding fixings reliable? Yes, IME. Can a bottom opening style meet the fire escape regulations. Pass. Why not go for full height casement with egress hinges? (and egress hinges often have an "easy clean" mode). |

Can a bottom opening style meet the fire escape regulations. Well, all my cheapy opening PVC windows are top hung and bottom latched. We have had one hinge failure in 35 years on a big 3.5H x 4W ft unit. This cost £35 to have replaced. The finish is still excellent even on the South facing units, which get full sun in summer. They are easier to meet fire escape regulations with as the access is so good. However, the opening mechanism must be childproofed to stop them committing suicide when they fall out which they try to do regularly. The locking mechanism is very flimsy, but the favoured tool for breaking in is a blow lamp, so that doesn't really come into it. Make sure the glass is fitted from the inside, this is easier to fit and more secure. |

I am very pleased with the aluminium double-glazing I've had in my 1901 terraced house for 25 years - it is unobtrusive. Another thing I was careful to avoid is non-flat glass, which I often see.

By the time they have put in the plastic thermal break and endless folds for strength and appearance they are as fat as uPVC. Why replace the existing windows? Just fix them like for like if they're misting. Elsewhere, the architect has specified 4-20-4 argon filled. The existing window rebate is much too narrow. Also new windows will be visible on the frontage and jar with the existing. You can specify what you like, as long as it meets BR. Thoughts please. Does uPVC really stay clean and shiny for 20 years? the gloss goes & it becomes somewhat uncleanable. If facing onto a street there's also a slight risk of cigarette burns. I'd plan on a set of windows staying for a lot longer than 20 years! Isolated plot, set back from the highway. With new PVC I'd go for external glazing. The advantage is that when the sealed unit seals fail (not if), they don't mist up & don't need replacing. Please enlarge. I thought the only difference was whether the burglars could prise them out. That's the usual reason quoted for internal glazing, but imho it's a bit of a false one. External glazed windows use glazing tape, a very tough adhesive that prevents that. To get in you'd need to take the same measures required to enter through internal glazed windows. Unsealed DG mists because the inner space is exposed to the same water vapour level as indoors, but the temp is lower. Expose that space to the lower outdoor water vapour levels and it simply does not mist. External glazing does the latter, internal glazing the former. Have you considered new durable species timber windows to match the existing? (but with deeper whatsits.) Not yet. This will be out last house and I am trying to avoid predictable maintenance. hence I said durable species. If you go for ali windows, beware of colour finishes such as powder coating. Nothing sticks well to ali, lumps come off in time. They only reliable way to colour ali is anodisation. OK. There doesn't seem to be a raft of disgruntled powder paint owners out there. Well, that's how ali is. Nothing sticks to it forever. Google can confirm. NT |
