All our windows have 28mm seal units, which consist of two 4mm panes of glass with a 20mm air gap incorporating a warm edge spacer bar. Units as such are more thermally efficient than aluminum bars, because aluminium is an efficient conductor of hot and cold temperatures which can contribute to a sealed unit breakdown. With 28mm sealed units there is also the added soundproofing benefit, which is convenient for anyone that lives on a main road or busy street.

In order to comply with part ‘L’ of building regulations, the glass we use in our sealed units features Soft Coat Low Emissivity Glass. This glass has a thin metal coating, designed to reflect the heat back into the room whilst still allowing the sun’s heat to pass through.

The glazing we supply complies to BS EN1279-2. This means our sealed units have been independently tested for moisture absorption which can lead to sealed unit breakdowns such as steam or condensation build up inside the sealed unit.

All our uPVC windows use 100% new plastic, which hasn’t been used, consumed or processed or subjected to processing other than for the purpose of being used as a window profile. Using new formed plastic material, can absorb more of the sun's UV rays, preventing the uPVC from discolouring and holding its pure white finish for a longer period of time.

Within the canopy of our box windows, we use glass reinforced plastic (GRP), which is a highly versatile material that is flexible, lightweight and super durable. GRP is highly resistant to corrosion, ultraviolet light, excessive temperatures, salt air and acidic chemicals, as well as any wear and tear, pressure or damage.
