Modern day performance for historic windows.

Vacuum Glazing allows window restorers to breathe new life into historic frames. Existing timber frames can be given modern day performance whilst still retaining as much of the original units as possible. This means that owners of listed properties can enjoy vastly improved energy efficiency and sound proofing while satisfying local planning officers.

Addressing Your Specific Needs

Let’s address them:

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.

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.

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!
