HIGH-IMPACT ACRYLIC

Impact Resistance - Chemical Resistance - Execellence Weather Resistence - Clarity & Radiation Filtering

HIGH-IMPACT ACRYLIC

High Impact acrylic transparent roofing sheets are specially developed for versatile range of applications.

The composition of resins is unparalleled in combating the effects of UV degradation and effects of corrosive environment, ensuring that the transparent roofing maintain the clarify, allowing maximum light transmission and with no changes in its properties over long periods of time.

High Impact acrylic transparent roofing sheets are well known and very sought after for their durability, weatherbility and chemical resistance. The roofing sheets are the perfect choice of skylight roofing material as it offers the best of both worlds in terms of performance.

KEY ADVANTAGES OF USING HIGH-IMPACT TRANSPARENT ROOFING SHEETS

Utilizes 100% virgin grade acrylic resins that are fully imported, ensuring high quality.

Offers superior UV and chemical resistance, at the same time providing up to >93% light transmission.

Superb weather ability ensures that the roofing sheets retain its properties and clarity over long periods of time, which prevents yellowing and embrittlement of the sheets.

Suitable for application of extreme levels of corrosion, e.g. coastel areas with high levels of salt spray, chemical plants, oil and gas industry, manure drying beds.

Delivers impact strength 10 times greater than normal acrylic.

Available in all range of roofing profiles and lengths to suit your requirements.

We utilize special impact resistant grade of acrylic that provides additional impact proof characteristics without any loss of characteristics of acrylic resis. The end result is a product that has all the useful benefits of acrylic with ease of transport and assembly.

Solar Energy and Visible Light Transmittance

LIGHT TRANSMISSION OF Acrylic (PMMA) : 93% for colorless and transparent Acrylic. It transmits 93% of visible ray and reflects the rest of it. Vermax Impact Acrylic roofing sheet absorbs short wavelength ultraviolet (UV) energy, but transmit most of the long wavelength UV (those wavelengths just short of the visible region). The total UV energy absorbed is about 65%.

High Impact Acrylic roofing sheets exhibits unsurpassed UV stability and thus excellent weather ability.

PMMA has the highest light transmission among the plastics resins; especially its ligt transmission is superior to glass. Light transmission of PMMA is 93% betwwen 380 nm ~ 780 nm but that of PC only 87% between 480 nm ~ 680 nm.

Extreme Weatherability

High Impact Acrylic roofing sheets show minimal hazing ( loss of clarity ) haze test results after two thousand hours of sunlight exposure show that the haze for acrylic makes a steady albeit marginal increase, as compared to other resins.

At the same time, High Impact Acrylic also exhibits a low initial yellow index. In other words, it hardly changes despite of long-time expose over 2000 hours, while as compared to other resins.

High Chemical Resistance

High Impact Acrylic roofing sheets are highly resistant to most common chemicals, acids, alkalis, solvents and thus is suitable for application in extreme corrosion environments.

INSTALLATION GUIDE

Handling and Storage

Transport and storage Vermax^® High-Impact Acrylic Transparent Roofing Sheets horizontally on flat.

Avoid storing unwrapped Vermax^® High-Impact Acrylic Transparent Roofing Sheets.

Short Vermax^® High-Impact Acrylic Transparent Roofing Sheets should be stacked on top of longer ones. Do not stack up more than 1 meter in height.

Store Vermax^® High-Impact Acrylic Transparent Roofing Sheets in a cool, dry and shaded place, protected from direct sunlight. Avoid covering the stacks of Vermax^® High-Impact Acrylic Transparent Roofing Sheets with dark or heat-absorbing materials objects , to prevent solar heat build-up.

Recommended handling:

Protect the sheets from any physical damage.

Avoid stepping on the panel when it on the ground.

Avoid folding panels across the corrugation during handling and installation.

Do not drag the Vermax^® High-Impact Acrylic Transparent Roofing Sheets on the ground or scrape them against structural elements or other rough objects.

Processing

Cutting

Use fine-toothed tenon saw.

Power saws with abrasive cutting-off wheel or circular saw blade suitable for cutting Vermax^® High-Impact Acrylic Transparent Roofing Sheets with dark or

Jig saw with suitable blade may be used as well.

Drilling

a) Pre-drill the required fixing holes to at least 4-5 mm larger than the diameter of the screw used. (e.g. Diameter of screw 4mm, hole drilled required minimum 8mm or larger)

b) Power drill may be use at LOW SPEED and the drill bit must be ground to suit the Vermax^® High-Impact Acrylic Transparent Roofing Sheets with dark or

Avoid drilling hole punching.

Drilling vertically at 90 °

INSTALLATION GUIDE

Roof Details

Pitch

The minimum recommended roof pitch for Vermax^® High-Impact Acrylic Transparent Roofing Sheets application is 6° (10% slope).

For roof pitch less than 10° (1:5.6) apply full sealing system (one sided foam tape) on all lapping and drilled holes.

Purlins

Roof purlins must have a level face parallel to the Vermax^® High-Impact Acrylic Transparent Roofing Sheets.

The allowed maximum roof span (purlins distance - center to center) is 1.2 meter.

Positioning

Lay the Vermax^® High-Impact Acrylic Transparent Roofing Sheets to overlap the metal roof panels on both sides. If not feasible - Vermax^® High-Impact Acrylic Transparent Roofing Sheets must underlap the metal roof panels side against the primary direction of wind/rain.

Vermax^® High-Impact Acrylic Transparent Roofing Sheets must be located and installed without any stresses. Do not pull, stretch or force the sheets when the profiles are not perfectly matched.

Overlaps

Recommended longtitude overlap of minimum 300mm above purlin.

Each Vermax^® High-Impact Acrylic Transparent Roofing Sheetsto extend 150mm or over the fixings along the purlin.

Recommended one sided foam tape on both sides of fasteners line.

Side-laps

Recommended one sided foam tape along the centreline of the corrugation ribs.

Fastening

Pre-drill 12mm or more holes at the screw points.

Fasten screws on every purlin from the lower end towards the upper end sequentially, starting always from the same side.

Always fasten through the ribs of the Vermax^® High-Impact Acrylic Transparent Roofing Sheets. Do not fasten screw on the valley.

The screws should be tightened moderately, without deforming the washer and distorting the Vermax^® Polycarbonate Transparent Roofing Sheets. Careful attention should be given to assure perpendicular insertion of the fasteners.

Excess tightening and oblique insertion will distort the Vermax® High-Impact Acrylic Transparent Roofing Sheets induceundue internal stresses, leading to fracture and cracks, eventually ending in failure.

Screws fasten positioning vertically at 90°. Screws fasten position at the center of the pre-drill hole and not the side or corner of the pre-drill hole.

Do not fasten screw at the side or corner of the ribs.

Never use an impact wrench or driver for fastening Vermax^® High-Impact Acrylic Transparent Roofing Sheets. Tighten by handor by an adjustable torque power screwdriver.

Do not use Drive Screw' Nails or Pop Rivets.
