Secondary Double-Glazing Kit Magnetic & Steel Tape 12.7mm, 5m Roll Each Foam Tesa 4957 Adhesive

Secondary Double-Glazing works as an additional layer of glazing for your existing windows.  This will form a double glazed solution which you can fit yourself. Once fitted, the double glaze can easily be removed when not required. Secondary glazing helps with heat retention and reduced sound and is ideal for buildings where renovations are not possible; such as listed buildings.
