The Ultimate Solution for Compliance with Modern Regulations
A cutting-edge hybrid glazing unit designed to meet the highest energy efficiency standards in Europe, while also having maximum flexibility in performance and unit construction. Ideal for both reglazing modern windows and manufacturing new, sustainable windows, LandVac Optimum offers superior performance, meeting and exceeding Modern Regulations for energy efficiency.
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.
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.
