A choice of glazing options to meet your requirements

hero image

At ROOF maker we manufacture all our rooflights using our own Reflex® Glass product. This is a specialist UV and IR blocking glass with super insulating properties to reduce heat loss from your house, every unit is branded in the corner with the Reflex® glass logo to insure 100% genuine product and all of our glass is manufactured to  to BS EN12150 standards.

 

Thorough quality standards throughout the manufacturing process

 

Because we make the glass units in house (other manufacturers buy their glass units in) we have total control of our product quality and design more features in to our glass, with unit seals 80% deeper than anyone else in the industry. The deeper the seal, the longer the unit life and our units have a life expectancy of 30 years. Our popular flat rooflights products feature a Tri-seal system that seals the glass three times:

  1. Continuous Acrylic Primary Adhesive seal – only one jointed corner
  2. Bostik P5125 Hotmelt Secondary Super Vapour Seal – 80% deeper than the industry standard
  3. Two part Dow Corning structural adhesive glass to aluminium – 90% thicker seals than any competitor

 

Glass has come a long way since double glazed units were first introduced. Choose a ROOF maker product and you can choose from four distinct Reflex® glass options, which may be selected individually or combined for even better performance. All of our glass units have a low-maintenance, self-cleaning coating as standard and filter up to 100% of harmful rays to prevent bleaching of your fabrics and furnishings.

 

Designed to target your key concerns

 

Our glass range has been designed to address four common concerns:

  • Energy saving
  • Temperature control
  • Noise pollution
  • Security

Energy Saving

All our glass offers exceptional thermal insulation, to prevent heat escaping during the colder weather and keep your heating bills down. The effectiveness of a product’s thermal insulation is indicated by its U-value. The lower the U-value, the better the insulation.

 

A lower U-value can be achieved by increasing the number of panes of glass. For example, triple glazing has a lower U-value than double glazing. As a guide, a standard double-glazed window typically has a U-value of 2.8 W/m².

Energy is the name given to our standard glass.

 

Glazing comprises two or three panes of 4mm or 6mm toughened safety glass. Each pane is separated by a argon-filled cavity and a foam spacer. This structure is designed to provide exceptional insulation, reducing heat loss from your property and keeping your heating bills down.

 

The glass offers outstanding U-values, which can be as low as 0.5 W/m²K, depending on your chosen product. Energy is ideal if your property is north or east-facing, as it will give you maximal light and heat during the morning.

Temperature Control

In winter, you need your room to retain heat and stay warm. During summer, direct heat from the sun’s rays can make your room uncomfortably hot. This is known as solar gain. A product’s ability to minimise solar gain is measured by its G-value. The lower the G-value (usually expressed as percentage), the less heat gets through.

Solar Performance has all the great features of our standard glass, plus a solar reflective coating to repel heat from the sun. Like our standard glass, Solar Performance has low U-values to keep heat in. It also has low G-values to minimise solar gain. In short, this means the glass will keep your room warmer in winter and cooler in summer. Dependant on product, we can achieve G-values as low as 23%.

 

Solar Performance is recommended if your property is south or west-facing and catches heat from the sun during the hottest parts of the day. Glare from the sun can be reduced with the addition of a blue or bronze tint, or by installing a blackout blind.

Noise Pollution

If you live in a particularly noisy area — for example, next to a busy road — noise pollution could be an issue. While opting for triple, rather than double, glazing can reduce outside noise, additional measures — such as lamination, thicker panes and wider cavities — can reduce it even further.

Acoustic Performance offers all the benefits of our standard glass, plus more effective insulation against outside noise caused by traffic, neighbours and other factors. The improved noise reduction is achieved by using laminated panes, which are slightly thicker and spaced further apart.

 

Acoustic Performance is most effective when used in triple-glazed products.

Security

Home security is a widespread concern these days. For homeowners, this means making potential entry points, such as bi-fold doors and rooflights, as secure as possible. All our glazing features toughened glass as standard and our bi-fold doors are security tested to PAS 24. This can be made even more secure by using laminated toughened glass.

 

Unlike standard glass, laminated glass does not shatter on impact. This is because its plastic interlayer keeps the sheet in one piece.

Our Security Performance range uses our standard glazing composition with laminated glass. This makes it much more difficult for an intruder to break through. The toughened glass is primed with a plastic interlayer, which stops it from shattering and keeps it in one piece.

Passive House Standard

Passive house is the ultimate energy efficiency status. It was originated in Germany during the late 80s and early 90s. The concept involves maximising the energy efficiency of a property by reducing its ecological footprint. The result is an ultra-low-energy building that requires little energy for space heating or cooling.

Our Ultimate Performance range is designed with Passive House standards in mind.

 

If you choose one of our triple glazed products, we can offer you a glass choice that meets Passive house standards, with U-values as low as 0.2 W/m²K

U-values and G-values will change dependant on the rooflight you choose, and the size that you specify. However, the following table of values should serve as a general guide to how each of our glass types impacts on performance.
