Sealing the joint of aluminium structures against draughts

Sealing the joint of aluminium structures — taping the connection between two frames to protect against draughts and cold-air infiltration in winter.

When separate aluminium frames are joined together during installation, the joint is sealed so that cold air cannot pass through the seam.

What the video shows

• Two strips of sealing tape are applied to the joint between the two frames;


• The tape creates additional protection against draughts and cold-air infiltration;


• The purpose of the sealing is to stop cold getting through the seam in winter.

Careful sealing of the joint improves protection of an aluminium structure against draughts at the connection points.
