Air Tightness

This refers to how much cold/hot air enters into a building, or how much is lost through gaps, cracks and holes.

Our roof lights have been designed to maximise on air tightness, ensuring that the very minimum amount of air escapes or enters your home. With less air leakage, you will reduce your energy consumption and costs.

Argon Gas

Argon gas is a type of noble gas which helps to increase energy efficiency when injected in the cavity of glass panes. Argon provides extra insulation and also improves sound proofing.

Actuator

An actuator, or motor is responsible for lifting a roof light into the open position and can be controlled via a switch. In our units, the actuator is built into the kerb to maintain the contemporary design.

Decibels (db)

Decibel is a measurement of sound pressure level. The decibel measurement indicates how effective the external sound is insulated by. The lower the decibel reading, the more insulation provided and the less sound coming in, or escaping.

CE Marking

CE marking is a certification that a product is in compliance with EU legislation. All of our products are CE marked, giving you the confidence that our roof lights are approved for sale.

DANAK

This is the Danish Accreditation and Metrology Fund, a company that handles the accreditation of certification and inspection in Denmark.

As exclusive stockist of the SkyVision series by Vitral, The DANAK certification is important as it shows that the manufacturer meets the strict guidelines set by this body.

DS Certified

The Danish Standard is Denmark’s national standardization body. Our rooflights have been fully DS certified again emphasising the quality of our products.

Flat Roof

Most commonly found on single storey extensions, flat roofs are generally cheaper to construct than a tiled alternative. Our rooflights are designed for installation on flat or low-pitched roofs.

Gasket

This is the rubber seal that fills the space between two surfaces to avoid leakage. All of our roof lights include this feature as standard.

Insulated

Insulation reduces heat loss by providing a barrier between areas of differing temperatures, i.e. the inside and outside of your home. By choosing an insulated rooflight and kerb you will let more light into your home, whilst still remaining energy efficient.

Laminated Glass

This offers increased protection to ordinary glass, with sound proofing properties too. It has an interlayer which holds the sheets together and greatly reduces the danger of small sharp fragments when obstructed.

Krypton

Like Argon, Krypton is a type of noble gas which is injected into the panes to improve energy efficiency.

It is more effective than Argon, especially when used in triple glazed units with a narrow cavity. We use Krypton in our Eco rooflights to ensure an ultra energy efficient product with an exceptional U Value.

Silk Screen

This is the banding on the glass which protects the upstand and rubbers against UV rays which can otherwise cause damage. All of our products come with silk screen banding as standard.

Sky Lights

Sky lights and roof lights are the same. The term roof window is also occasionally used, but all of these terms are interchangeable.

Thermal Efficiency

This measures how effective your roof light is at maintaining heat. Those that are well insulated will be more thermally efficient. This is recorded as U Value – the lower this value is, the more efficient your frame is.

Toughened Glass

This type of glass breaks into small shards when it is smashed. It has a high resistance to breakage as it is crafted by heating glass above 600°C and then rapidly cooling the surfaces whilst maintaining the heat in the middle.

Transformer

The transformer is an electric device that reduces mains power to low voltage required to operate our electric rooflights. We include a transformer as standard.

Upstand

Roof lights for flat roofs are supported by an upstand or kerb. Current building regulations require a 150mm upstand which we supply with all our products. Our upstands are pre-insulated to ensure they satisfy and exceed regulations and are the perfect fit.

U-Value

Thermal transmittance or efficiency is commonly known as U-Value, and is the measurement of the rate of heat loss. Recorded as W/m2K (watts per square metre, per degree Kelvin), the lower this value is, the better.

Water Tightness

This is a test of how water penetrates materials, and is conducted by applying water spray at a particular measurement per minute to the outside of the roof light whilst steadily increasing the air pressure.

They were extremely efficient and most of all knowledgable about their products - they offered detailed information and were extremely patient with all my questions. They managed to ship the product very quickly and it arrived to us the same week. Very happy with EOS. The product itself is great!

The roof light that I ordered arrived on time and appears to be very well made. The instructions were clear and my builder had no problems installing it, other than in getting it onto the roof as it is very heavy. The roof light looks good and I am glad that I was able to buy one with such a good U value as I wanted the light without the loss of heat.

EoS and their staff were very helpful in design and specification for a large skylight. They gave top quality support in the runnup to installation and were very accommodating in helping to source correct vehicle to crane in said (very heavy) skylight.

I'm delighted with my EOS roof lights. I had to choose roof lights that were slightly smaller than I wanted, due to design constraints, but the amount of light provided is wonderful and unexpected. The whole kitchen is lit up, even when the curtains are closed across our french doors. Many thanks EOS, A happy customers.

Really nice company - fast, efficient and pleasant in all my dealings with them. There was a delivery error and they worked hard to find a solution as quickly as possible and did everything they said they would. Really impressed all round - when you are having an extension on your house, you end up dealing with lots of suppliers. I wish they were all as good as EOS.
