Excellent weather resistance

Lavenda Door & Window Systems Consist of Polyvinyl -
Chloride, Stabilizer, Titanium Dioxide etc. in order to withstand various kinds of weather condition, ultraviolet rays and rapidly changing weather while the frame structure can slightly expand or contract. It is able to withstand high temperatures of up to 82oC without defects. This means that long-term sunny conditions do not cause the profile structure to break or deteriorate in quality,
throughout the whole life time of your windows.

Excellent heat insulation and energy saving

According to a recent survey, 37% of household energy is generally lost through windows. Proper selection of windows and glass would enormously cut down this energy loss. Lavenda Door and Window Systems with 20 mm insulated glass thickness, could conduct the K value of 1.74 W/m2K, compared with 7.50 W/m2K for general aluminium window frame. Therefore Lavenda doors and windows cut down energy loss far better than any aluminium window. This is because Lavenda Door and Window Systems are made in hollow
sections (multi chamber system) by an extrusion process, which lowers external heat dispersion into the inner area.
The Profile wall thickness is 2-3 millimeters. (Polymer material is a bad conductor, therefore heat compensation is achieved in this wall thickness.)

Excellent water resistance

Lavenda Door and Window Systems employ a corner welding
process to ensure that the window or door corner is completely
welded into a single structure; therefore, water is unable to pass
through the welded joint. Additionally, a double layer of EPDM rubber gasket is placed around the sash and the frame to
efficiently seal the gap.
(EPDM rubber gaskets are made from the same rubber used to seal windshields in the automobile industry, and are fully replaceable).

Excellent sound proofing

Lavenda Door and Window Systems have multiple chambers inside the profile structure while the hardware system is equipped with a multi point locking system to ensure proper closing and tightness. This efficiently reduces noise disturbance from outside, down to one-eighth of the original noise level (should reduction ratio is between 33 - 43 dB).

Corrosion resistance

In cities with high pollution levels such as Bangkok, Manila, Seoul or Tokyo, Lavenda Door and Window Systems can withstand
any corrosion caused by such conditions. Even in beach area
residencies, humid weather is unable to corrode or damage our

Excellent fire proofing

Lavenda Door and Window Systems are fully self extinguishing. Polymer, the material that Lavenda Door and Window Systems are made from, is noncombustible, due to its high chlorine concentration, and the use of appropriate compounds, Lavenda Door and Window Systems are manufactured under DIN 16 830 standard, guaranteeing your safety.

Attractive appearance

Lavenda Door and Window Systems are built with smooth surfaces and properly welded corners. The profile color will not turn yellow or fade after a few years of use. Frequent cleaning is possible without any repainting throughout the useful life of the frame, so the maintenance cost is low compared to wood.

Environmentally friendly

Lavenda Door and Window Systems are made from ecologically friendly materials and environmentally safe in terms of less pollutant emissions than wood and aluminium. Polymer is recyclable, and so there is no lost material as all waste goes back into the recycling process.
