Daylight Systems

What system will meet your needs?

Your Solatube® Daylighting System is tailored to suit your home, so to determine the exact cost of your system you will need to know:

1. The Solatube® size (diameter) you require
2. The length of tubing required
3. The roof flashing type required

BBelow is advice on how to determine these three requirements; once you have done this you can check our Solatube® price list for the exact cost of your system.

What size Solatube® Daylighting System do you require?

This will depend mainly on the size of the area you wish to illuminate – below is a guide. For larger areas or long narrow corridors or hallways, Solatube® Daylighting Systems can be used in multiples.

Do also take into account the ceiling height — if it is much higher than average you may need to consider a larger diameter system.

How much tubing is required?

To determine how much tubing is required you will need to measure your install distance – the distance between the underside of the roof and the ceiling.

For install distances up to 400mm

No additional extension tubes are required; each Solatube® Daylighting System is supplied with a top tube and ceiling tube assembly that together give an install distance of up to 400mm. This is sufficient for a flat roof or vaulted ceiling installation.

For install distances over 400mm
For install distances greater than 400mm, you will need to purchase additional extension tubes; extension tubes are 610mm long and are joined together to make up the install distance required.
To calculate how many 610mm long extension tubes you require, determine your install distance, then use the chart below to calculate the number of tubes required.

What roof flashing do you require?

Our roof flashing range covers virtually all UK pitched and flat roof types and they are designed to ensure a weather-proof and maintenance-free installation. No environmentally-unfriendly lead is required to fit Solatube® flashings. We recommend the use of Solatube® flashing insulators to re-seal the cut felt membrane on the roof – please see our Accessories page for further details of flashings insulators.

Please contact us if you need any advice regarding a suitable flashing for your roof type. Above are some examples of our most widely-used flashings; we are also able to supply flashings for more unusual roof types such as thatch, standing seam, metal roof tile, wall-mounted and land homes, and can advise on flashings for listed buildings and homes in conservation areas.
