Polycarbonate Twinwall Overview

Twinwall polycarbonate provided by Interstate Plastics is the ideal glazing material for many outdoor applications including roofing, hobby and commercial greenhouses and window replacement. Twinwall’s notorious double paneled sheets serve to trap air, therefore increasing the product’s insulation strength. Insulation properties will increase depending on the material’s thickness.

Twinwall’s surface is protected from the degradation effects of UV radiation by a proprietary co-extrusion process. Beneficial infrared light passes through the material promoting an ideal growth environment. UV-resistant Twinwall is twelve times lighter versus glass and the resins comprising the material are specially developed for excellent flame retardant properties.

Polycarbonate Wind Load Charts

These charts show wind loads and sheet deflection that should be taken into account when designing a covering. Use of the graph indicators is quick and easy, and is intended to provide information of a type generally acceptable in civil engineering. Each chart provides data for 3 different sheet widths with the maximum proportional deflection being 1:20 or 5% of the specific width.

The right-hand area, where the curves become more horizontal, measures specifically and only sheets clamped at 2 sides. The left-hand area measures specifically sheets glazed in frames with supports perpendicular to the sheet ribs. For structures built in areas with variance in meteorological conditions, the use of adequate safety factors is recommended in order to reduce risks.

The data and information in this section is given in good faith but only as basic technical support for engineers of various structures. In no way can this information be substituted for the responsibility and liability of the designing engineer of a structure as determined by law. The information pertains to the roofing material only and does not in any way determine the strengths required in a supporting structure or in various glazing systems.

Polycarbonate Twinwall Applications

Polycarbonate Twinwall is used in construction and agricultural industries as well as many DIY applications.

Design & Architecture
Polycarbonate Twinwall finished plastics give a sense of openness and flow while maintaining protection, durability and strength for years to come.

Agriculture & Greenhouses
Virtually unbreakable, withstands UV rays, hail and extreme weather. Multi-wall sheets provide the best thermal insulation of any greenhouse and agricultural coverings.

Windows, Glazing & Light Transmission
Enlist nature's qualities for interior atmosphere. Perfect for building lighting, open passageways, pools, verandahs, interior design elements, display windows and exhibitions.

Weather and Impact Protection
Weather and impact protection that lets light in. Lighter and easier to install versus metal and more protective than wood, you can rely on a certified hurricane protection system.

Patio & Awnings
For home and commercial design, Twinwall is like putty in your hands – almost any project, however unique it may be, can be implemented with polycarbonate Twinwall.

DIY
From wind shields to shelters, custom greenhouses and art projects, polycarbonate twinwall can be cut and drill using standard wood working tools. It's also good for drilling, trimming, bending and bonding (use Weld-On 55 "glue").


Working with Polycarbonate Twinwall

Cut and drill using standard wood working tools:

Cutting can be done on a standard circular, jig, or table saw with a blade having 8-12 teeth per inch. Thinner gauges can be cut with a box knife.

Drilling is performed with standard wood drill bits.

Trim with a standard box cutting knife.

Bending is done by cold forming along the direction of the flutes. Bending guides are available.

Bonding ("gluing") can be done with Weld-On 55 adhesive.


Greenhouse Solutions

Get growing with the Snap & Grow 6' x 8' Silver Frame Hobby Greenhouse from Palram. Heavy duty aluminum frames assemble easily without much hardware. Crystal-clear polycarbonate panels slide right into the frame, lock into place and are virtually unbreakable.

Aluminum framework, clear single layer polycarbonate panels, swinging front doors, rain gutter and roof vent are standard features of the Snap & Grow greenhouse. It comes with an easy to use set-up manual and is available in standard silver or a green powder coat.

Make any backyard a sanctuary — in a snap!
