Q.

What is 'External Manufacturing' Size?

A.

This is your External Kerb Size plus 30mm. This gives leeway to ensure the Rooflight fits the timber upstand perfectly.

Q.

'Thermally Broken' explained.

A.

Thermal breaks are polyamide strips to ensure that the aluminium is thermally efficient, this is done by rolling the two aluminium extrusions together with the polyamide- this will stop condensation and heat loss. A lot of systems out there are just made of a single piece of aluminium, these cannot be classed as ‘systems’ and have no test results as they are not thermally efficient in any way by design.

Q.

What’s the difference between fully tested and a ‘calculation’?

A.

Calculations can estimate the U-value but are not accurate and can be manipulated to your favour. Having this done through a government accredited testing facility gives real accurate U-values with no manipulation just true test results.

Q.

Why is it important for Rooflights to be fully tested?

A.

We ensure all our products are fully tested to meet with strict building regulations and specific design requirements.

Q.

What’s the difference between Silicone Sealed Units & Hot Melt Units?

A.

Overtime UV rays breakdown hot melt sealed units, so we use only silicone sealed units as they do not degrade under UV rays. Silicone sealing is expensive but lasts longer and out performs hot melt. You will find silicone sealed units are mostly used in structural glass applications such as skyscrapers etc.

Q.

What if the Flat Rooflight is too large for one pane of glass?

A.

The glass can be split into smaller sections with the design of a glass beam or a structural beam that the glass is bonded to. This allows you to make much larger rooflights with the ease of transportation and installation without the need for costly lifting equipment. For narrower Rooflights, we can use a structural glass to glass join for a more ‘Frameless’ look.

Q.

What’s the difference between glass to glass joins and the usual bars you find in standard Roof Lanterns?

A.

Replacing bars with structural glass to glass joins means we can achieve better U-values, keep the Lantern more thermally efficient yet still maximise light with much thinner hips and ridge. Overall, accomplishing a more aesthetically pleasing and neater product by design.

Q.

What’s the maximum size glass unit thickness that can be used in our systems?

A.

Flat Rooflight......................... up to a 45mm unit
Roof Lantern......................... 30mm unit only
Opening Rooflight................ up to a 36mm unit
Balustrade...........................17mm Toughned Laminate

Q.

Do we install?

A.

No, we are purely a systems company that design & manufacture for supply only. However, depending on your location we can pass you through to one of our distributors for your installation needs.

Q.

Q.

We already have a glass supplier, can I purchase just the frame?

We already have a glass supplier, can I purchase just the frame?

A.

A.

Yes- our Flat Rooflight, Roof Lantern & Opening Rooflight systems are available to purchase as a ‘manufactured frame only’.

Yes- our Flat Rooflight, Roof Lantern & Opening Rooflight systems are available to purchase as a ‘manufactured frame only’.

Q.

Can I install your Rooflights onto any roofing substrate?

A.

Yes, this is no problem. As long as the rooflight is being fitted onto a timber upstand, and the correct sealant is applied depending on the substrate.

Q.

What’s the minimum and maximum pitch for your Rooflights?

A.

Flat Rooflight........................................ 5 - 45 degrees
Opening Rooflight.............................. 5 – 15 degrees
Roof Lantern........................................ 0 degrees only

Q.

What if the Rooflight needs to be installed against a wall?

A.

This is not a problem, we can manufacture the Rooflight to suit the wall abutment detail.

Q.

Can our Frameless Roof Lantern vary in pitch?

A.

Due to our aluminium extrusions, our Lantern is set at a pitch of 40 degrees as a standard, and cannot be changed.
