Window Board Draughts

michdee

Hi, we have a fairly new house. We put in pine window boards as the cills and then the windows were put in, however as time has past the pine window boards have warped:mad: leaving a breeze / draught coming in right where the window board meets the windows. Its ridiculous the breeze that comes through it. Is there anything that can be got to help alleviate this??

caulk

You could fit quadrant along the Window in conjunction with Caulking which should cure the problem.

There should be no draught what so ever even with the boards pulled off.

I would take them up and seal the gaps properly with some Tape like contiga SL then refit the boards again.

Caulk is a short term answer and really not stopping to origin of the draught which appears to be the bottom of the window installation

+1 here.

Is the house a TF?

My guess is that the wall vents are not properly ducted into the inside face of the plaster board so take off an internal wall vent, take some pictures and post them and let's see

Thanks all house is concrete house. I don't think the boards can come off.... Used chaulk under boards but this is on top where cill meets window

michdee

You can nearly even see the gap here along the window and cill

I had similar problem a while back, the draft was coming form underneath the cill after new windows were installed, looked under and there was a gap of half an inch between the cill and the wall only thing ''retaining'' heat was chalking from the outside...

Bough a bottle of macroflex or what you call it this yellow expanding foam? did the job just fine

I'd say look from the outside at the bottom of the window where it meets the cill as the inside might be well plastered, remove a bit of chalking and you may be surprised what you find inside

michdee

Thanks did that got outside sealed under windows exact as you said. It's terrible all these things that happen

It's amazing how many draughty windows are still fitted to new houses. All the U-value figures that window companies like to shout about are not worth anything if the windows are not sealed properly.
Expanding foam is not really a fix as it is not fully airtight.
The only real way to do this permantly is to use air-tightness tape which can be got in any builders providers.
It's not costly to do but can be tedious if you have to a lot of windows.
Chances are the rest of your windows haven't been properly sealed either.

After a bit of investigation over the weekend. Where the window meets the cill if I push the window you can see it moving, is this correct should it be like this?

The window shouldn't move at all.

Thanks will get onto the window crowd and see what they've to say so. Couldn't believe how could see it moving with simple push and I only used two thumbs to do it!
