size windows

[jonnyp1]

i have a nice view and have planning permission to enlarge an existing dormer to take advantage. the new window would be 4.5m long and 1.4m deep, i want as much view and as little window frames as possible any advice where i can get such a window or do i have to have 2 with great big lump in middle of my view. also doe sanyone know if i will need steel for that span or should i ask engineer to do calcs.

In short if you want it all open, then a steel will be required

Match the window to the rest of the house if you have pvc then go the same etc, remember you need openers for ventilation and timber will last 100+ years.

ahhh right, guessing were talking plastic here to get that in 1 piece would be awkward to handle you would need to rope it up the outside with at least 2 ropes and even unglazed it would weigh a bit, i see you are in hampshire so you could try a company called 7 day windows in camberley they are a supply only firm that make and deliver your windows in 7 days
I've used them and price and quality is good, if you can't find them i will dig the number out.

It's not every company that would be able to handle and supply a 4.5m sheet of glass. I ould contact Pilkingtons and St Gobain and ask them for names of likely suppliers.
A 4.5m lintel does not have to be steel. A gluelam (layers of timber glued together) beam has some advantages over steel.

Are you thinking of having a large centre pane say 1.8 wide by full height?
This size is determined by the max size and spec of the unit. You could then have 3 windows bolted together then. Also check the weight as a 4mm DG unit weighs 22 kg/sq metre. Trust me that is heavy
