How our tensioned external roof blinds work

An external roof blind has a similar construction to outdoor roller blinds featuring a cassette headbox to the top and guides to each side but uses a tensioning system to work on all angles for both horizontal and sloping glass.

A rollertube with integrated tubular motor and to which the fabric is rolled around is contained inside the headbox and features a spindle to each end. These spindles have hi-tensile Dyneema cables wound around them which subsequently run down each side guide, over a series of pulleys and into the leadrail, which the fabric is attached to. The cables put under tension a double coiled spring in the leadrail which keeps the blind fabric taut at every position even allowing it to work from bottom up. The leadrail is located and runs within the side guides ensuring the blind runs square and smoothly every operation.

The guides to each side are attached through face fix or side fix brackets to the structure the blind is covering, whether a rooflight frame, conservatory roof glazing bar or pergola beam and the headbox is self-supported through a lug mechanism on the side guides, requiring no physical attachment. The cassette headbox is in two parts with the top section (lid) easily removed to allow for any maintenance or remedial of the blind in situ.

The motor is radio controlled from either a remote control or wire-free wall switched and can be connected to sensors that allows the blind to think for itself, automatically positioning itself based on the suns intensity and wind.

External Blind Reviews

The service was excellent

We are really happy with the blind and the service was excellent from quote to fitting. I would definitely recommend you.

Holmes - Twickenham

Very impressive

Initial reaction is that the process and product have both been excellent. The fitters were very good, as were you… so far very impressive, and I would be happy to recommend you.

Wilkinson - East Molesey

An absolute pleasure

I just wanted to say that your service men were an absolute pleasure to deal with today! They are excellent ambassadors for Caribbean Blinds.

Reilly - Twickenham

The blind is incredible

I thought I would wait a little while to see how the blind was functioning before I contacted you again but I would just like to say the external roof blind has transformed the way we use our room. The space would have been virtually unusable over this summer but the heat reduction on using the blind is incredible. I am now thinking of other areas in the house that would benefit from external shading.

Robinson - Walton On Thames

The two fitters were fantastic

We are extremely pleased with both the blinds and the service. The two fitters were fantastic and we cannot wait for our awning now!

Taylor - Teddington

Really happy with the blind

Really happy with the blind, functions perfectly and the installers were great.

Rayner - St. Neots

Fantastic job

The team were very professional, did a great job and the product is lovely, really good quality. The best thing is that it looks like it has always been there, which helps fussy self-builders like us!

Fantastic job, thank you.

Cope - Staines

How pleased we are

Just to say how pleased we are with the blinds, although we have not had a chance to use them properly yet (and I suspect it will too cold for the next few days!).

Johnson - Egham

Great, professional and polite

I would like to say that from initial enquiry to completion of the job we have been very happy with the communications received and all subsequent questions answered to our satisfaction. Rachel was very prompt getting back to me in the early stages and the installation went well last Monday. The guys were great, professional and polite. We won’t know how effective the blind will be for a few months yet, but we are confident that we will not be experiencing 30-degree temperatures in our lounge again! We are happy to recommend your company to friends and family.
