The Look of Single Glazing, the Efficiency of Triple Glazing
Thermal Improvement of Existing Frames
Modern window and door frames should considerably outlast the lifespan of a typical double or triple glazing unit. As those units age, the performance of them reduces considerably until they fully breakdown and look unsightly.
Aluminium older double glazed (3.76W/m2K) Aluminium LV Optimum (2.22W/m2K)
PVC older double glazed (2.64W/m2K) PVC LV Optimum (1.07W/m2K)
Timber older double glazed (2.62W/m2K) Timber LV Optimum (1.01W/m2K)
The LandVac Optimum units provide the flexibility to replace existing double and triple glazing units in windows and doors without replacing the frames – giving you a cost-effective and minimally invasive method to thermal and acoustic improvement and a warmer home.
Flexible to Suit Your Needs
Although the units are modelled at 25.1mm thick, this is just an example. Your local distributor will be able to work with you to design the perfect balanced hybrid unit for your needs. It is also essential that the traditional cavity elements of the unit are constructed locally to ensure compliance with EN-1279.
