Window seal

Also known as a window gasket, a window seal is a strip of rubber that has been purpose-designed to hold glass firmly in place on the sash within the window frame.

At windows24.com, windows and doors come with double glazing in their most basic configuration to ensure good energy efficiency. Due to this, two window or door seals are used. One gasket is attached to the outer pane of glass, and the other gasket is added to the pane facing home interiors.

Glazing seals, whether for a wood, aluminium, or uPVC window, bring several benefits including:

• Prevention of water ingress and entry of cold drafts

• All-weather seal durability

• Accurate and sturdy glazing installation

• Sleek, matching gasket seal design

• Ideal for glass replacement

A rubber gasket seal is an ideal solution to ensure no gaps are left between the glass and the window or door profile. This is important to prevent the entry of moisture and drafts that can reduce insulation and lead to mould.

As glass differs in thickness depending on whether a triple or double-glazed unit is used, a made-to-measure gasket rubber seal on either side of the glazing ensures the glass will perfectly fit the frame. This adds an impressive accuracy in terms of the manufacturing of our products, from a uPVC window to large patio doors.

The window gasket or door seals then also apply the correct amount of pressure onto the triple or double glazing, increasing the sturdiness of the glass and holding it in place for long lasting use.

An alternative method of holding triple or double glazing to the frame and sash of wood, aluminium, or uPVC windows and doors is use a silicone glue adhesive. One of the issues with this technique, however, is that the silicone must be cut if the glass needs to be removed at some point. With gasket seals, however, glazing can be easily replaced, and a replacement gasket, which fits the new glazing, can be ordered from us if needed.

Unlike traditional adhesive, a seal gasket adds a professional, sleek finish to window and door profiles. Available in grey, black, white, and transparent, the gasket seal is manufactured into the product profile and will come in the best match. Whether produced for a uPVC window, full glass front door, or replacement aluminium windows with double glazing, a durable and subtle all-weather seal can therefore be relied on.
