Steel Window Manufacturers

In LandVac Heritage and LandVac Optimum units, plugs and getters are located within a 20mm border around the unit. These components are concealed within a standard glazing rebate, offering a sleek appearance. The aligning of getters and plugs along the same horizontal edge enables them to be located on the least conspicuous side of the window.

Commonly known as "the dots," these micro-pillars prevent glass panes from touching under the high vacuum pressure. LandVac's advanced technology ensures significantly fewer micro-pillars compared to other vacuum glazing options. Moreover, the coloration of the pillars makes them inconspicuous, rendering them virtually invisible when viewed from a standard distance of 2m.

While slim double glazing may have served its purpose in the past, the industry is rapidly progressing toward higher sustainability and energy conservation expectations. Slim double glazing falls short in terms of heat retention, exhibits double reflection even in the slimmest units, and has shorter lifespans with higher breakdown rates. By embracing LandVac vacuum glazing, you position yourself at the forefront of these advancements.

As energy efficiency requirements increase, manufacturers seek more efficient glass units. However, adding more glass panes and cavities results in a substantial increase in weight per square meter. This weight, combined with the market's demand for increased glass sightlines and larger pane sizes, poses challenges for manufacture and installation. Ironmongery systems struggle to keep pace with these changes, leading to potential reductions.

In new window construction, vacuum glazing is built for plant on glazing bars for a few main reasons: The thinness of the cavity and unit means that the bars appear to pass through even to the keenest eye. The cost per unit means that individual small units will make a product too expensive for the end client is most cases. The use of one large unit with planted on bars is hugely more energy efficient than a series of small units to the same overall size. In our experience, conservation officers are willing to accept this approach in all but the most sensitive Listed properties once they understand the huge benefits offered by this approach. In general, resistance to this type of construction is disappearing. Note: this is particularly important with steel as the glazing bars are not thermally broken, and small panes can have an even greater impact on U-Values as a result.

The maximum unit size 1500mm x 2500mm. Vacuum glazing units are actually more rigid than typical double glazing due to the vacuum, but as units get larger they may be made using thicker glass panes. The minimum unit size is typically 300mm x 300mm, but smaller sizes can often be made on demand. The minimum unit size for pricing is 0.3m2.

LandVac is available in a variety of shapes. The maximum width to Height ratio 1:6 for 8.3mm, if the ratio is any larger then it will need to be 10.3mm. Any shape with a right angle and single point of radius is possible. Isosceles triangles or right-angled triangles with a hypotenuse greater that 370mm are also possible. In all cases, CAD drawings must be supplied for any shape orders. If you aren’t sure, then just ask!
