Snap-down timber-supported glazing bars are designed to be used in conjunction with a timber support structure. They are commonly employed in conservatories, lean-tos, roof lanterns, and other structures that have a timber framework but require a system to hold and seal the glazing material.
Here are the characteristics and functionalities of snap-down timber-supported glazing bars:
Snap-Down Design: These glazing bars typically consist of a base section that's fixed to the timber framework and a top section (or cap) that snaps or clicks onto the base. This snap-down mechanism makes it easy to install the glazing material and provides a secure fit.
Timber Support: As the name suggests, these bars are not self-supporting; instead, they rely on the structural integrity of the underlying timber framework. The glazing bars act as clamping mechanisms, sealing and holding the glazing material in place.
Material: While the main support comes from the timber, the glazing bars themselves are often made of aluminum or PVCu. They provide both durability and an aesthetically pleasing finish.
Integrated Gaskets: These bars come with pre-fitted gaskets to ensure a watertight seal between the bar and the glazing material, preventing water ingress.
Top Caps: The snap-down top caps hold the glazing material in place. They can be removed if the glazing needs replacement or maintenance, making the system quite versatile.
Versatility: They can accommodate various glazing materials, including polycarbonate sheets and glass, provided the thickness matches the design specification of the bars.
Aesthetic Appeal: Snap-down timber-supported glazing bars offer an aesthetic advantage, combining the natural beauty and warmth of timber with the sleek finish of aluminum or PVCu bars. This can be especially appealing in settings like traditional homes or where a rustic look is desired.
Thermal Performance: With the combined insulating properties of timber and the sealing capabilities of the glazing bars, a good thermal performance can be achieved, reducing heat loss in colder months.
End Caps: Just like other glazing bar systems, these bars often come with end caps to provide a neat finish to the visible ends.
When opting for snap-down timber-supported glazing bars, it's crucial to ensure that the timber framework is structurally sound, as it provides the primary support for the glazing. Regular maintenance of the timber (like sealing or painting) will also ensure the longevity of the entire structure.
