How to seal aluminium sliding door and window frame?

imarshallwidjaj

Hi all!

I had a question about whats the best way to tackle stopping the draught coming from the joinings of the sliding door/window frame.

The draughts are coming through most of the joins between the frame and the wall and some of the joins between pieces of the frame itself. Pics:

It causes the corners to become really cold and condensation to form, enough that it dribbles onto the carpet.

My initial thought was to silicone everything but ive got no idea if thats a good idea 😥. What should I do?

Surprisingly the doors and windows themselves have very little draughting going on and its all around the frame that I can feel. Is there a good way to pin point where its actually coming from so im not filling the wrong holes? Sometimes using just my hands it feels like its coming from everywhere.

TIA!

Hello @imarshallwidjaj 

Thanks for sharing your question about sealing your aluminium sliding door. I suggest doing a double approach to seal your door from the wind outside. First, I suggest sealing the edge of the aluminium frame with Selleys 475g No More Gaps Interior Multipurpose Gap Filler. 

This will effectively stop any air leaks you might have that is surrounding the frame of your aluminium door. Next, I suggest using Raven Self Adhesive Weather Strip on the inside gap of your sliding aluminium door. You'll notice that there is a slight gap between your sliding door and the door frame itself. 

Your goal is to find a sealer thin enough that it fits into that gap and give your door a positive seal. I recommend looking carefully at the door and using a steel or wooden ruler to measure the gap.
