Before you begin
Questions about weathermaster.
Are Weathermaster windows the same as house windows?
No. Weathermaster uses flexible vinyl glazing for porches and seasonal outdoor rooms. Thermal house windows use insulated glass and frames for the home's weather envelope. Tell Dungate how you intend to use the room so the right system can be selected.
How much ventilation do four-track windows provide?
The vertical four-track configuration opens up to 75% of the window area. Horizontal two- and four-track systems are also available for different openings.
Can I buy Weathermaster supply-only?
Yes. Provide the required sizes and styles for supply-only pricing, or ask Dungate to measure, supply and install the complete enclosure.
