ENVIROGUARD double hung window

Double Hung Windows

The double-hung window is the most common style of window available, consisting of two window sash. Both upper and lower sash slide up and down on a double-hung window.

Impervious to rot and insects, the ENVIROGUARD™ BT30 block and tackle double-hung window series is not only pleasing to the eye but also durable. Constructed with the highest quality cellular PVC, these windows have all the natural characteristics of wood, including great appearance–without the shortcomings of wood. They won’t rot, peel, splinter, decay, absorb moisture–and they have enhanced screw-holding power.

Unlike vinyl windows, our cellular PVC double hung windows can be painted, look like real wood, and offer more glass space.

Finishing

Enviroguard should be painted with standard oil base or latex paint using industry standard painting techniques after cleaning.

Enviroguard product extrusions are cellular PVC, a vinyl-based composite. As such, they may be subject to thermal expansion and contraction at direct temperatures above 145 F degrees. Extreme dark colors may accelerate this situation, as dark colors tend to absorb a greater amount of solar heat, which can cause cellular PVC to expand and contract excessively and warping/distortion can occur. Distortion of frame and sash components, paint adhesion loss, blistering and peeling could also result. Painting Enviroguard products a dark color (any color that falls within the L value of 56 to 0) can generate high localized temperatures in the product.

WARNING: Painting any Enviroguard cellular PVC product with a paint color darker than L value of 56 (where black = 0 and white = 100 will forfeit the product warranty. If, despite the above warning, you should choose to paint Enviroguard products a dark color (as defined above), a paint specifically designed for these applications MUST be used. Whichever paint manufacturer is chosen must be contacted to verify the paint's reflective properties and suitability with regard to painting cellular PVC. Precision Millworks Inc is not liable for paint used on our cellular PVC components or the result of its use.

Beginning April 22, 2010, contractors performing renovation, repair and painting projects that disturb lead-based paint in homes, child care facilities, and schools built before 1978 must be certified and must follow specific work practices to prevent lead contamination. EPA requires that firms performing renovation, repair, and painting projects that disturb lead-based paint in pre-1978 homes, child care facilities and schools be certified by EPA and that they use certified renovators who are trained by EPA-approved training providers to follow lead-safe work practices.
