Draught Proof a Window

Usually large window gaps can be dealt with by filling with silicone rubber sealant. This works with both timber frame and metal frame windows - either externally or internally.

The process of sealing is as follows:

• Make sure the frame is thoroughly clean - use a damp cloth or such like.

• Squeeze a small amount of sealant on to the rebate of the fixed frame.

• Using a paintbrush, cover the closing edge of the window with soapy water. This acts as a release agent.

• Immediately pull the window shut to compress the sealant then open again.

• In fine weather the sealant should take around two hours to set. The beauty of this sealant is that it hardens on the surface, but retains a degree of flexibility underneath - this gives the desired seal.
