Triple Glazing

We continue to innovate and develop new products. With the predicted changes in Building Regulations which look set to demand lower U- values, our triple glazing solution, is an easy and cost effective way to comply.


We offer two aesthetically pleasing triple glazing beads, one chamfered and one Ovolo. The beads are stocked in standard finishes and they are also available in a different range of colours and woodgrain finishes.

Many variations of glass coatings, spacer bars, edge sealants and gas fills can be used to provide bespoke options to balance cost and performance. For example, triple glazed units, argon filled can deliver 0.8W/(m2K) whole window U-values.

Product features at a glance

Triple glazing can provide higher levels of thermal insulation than double glazing. Reduced energy bills therefore, reduced carbon footprint.

Two cavities for extra insulation

The use of simple additional components will allow an otherwise standard casement window to achieve a whole window U-value of 0.8 W/(m2K}

B66 allows the use of a 44mm IGU in Elite 70 and 40mm IGU in Elite 63

B55 allows the use of a 40mm IGU in Elite 70 and 40mm IGU in Elite 63

The Elite 70 44mm option provides two 16mm cavities for optimum performance using Argon fill (and not expensive Krypton fill). Making the Spectus solution possibly the most cost effective on the market.

or over thirty years, we have been at the forefront of PVC-U window and door design. Our British made systems are some of the most complete and advanced on the market. It’s no surprise therefore, that we offer such a wide range of triple glazing solutions.

the size of the cavity all impact on performance. The type of spacer bars and the edge sealants all make a difference.

Within the outer frame and sash, insulating foam or thermal barrier technologies can be used.

Low emissivity glass, the type of gas fill and how low you go with the U-values depends on what goes into the window. More features mean more savings in energy, but may also increase the cost.

The important thing to remember is that it’s possible to achieve a U-value of 0.8W/(m2K) with both the Elite 63 and Elite 70 systems without changing your outer frames or sashes.

Glazing widths include 36mm and 40mm for the slim line Elite 63 and 40mm and 44mm for Elite70.

Profiles are extruded under a quality management system that conforms to BS EN 9001:2008 and are kite marked to BS EN12608. Rest assured when you choose a Spectus system, your investment is in safe hands. Whatever the colour and finish you choose.
