Triple Glaze v Double Glaze Question

forzacalcio

Hi all

I know there are alot of variables involved on which is better but based on glass.

In theory which is better?

1.0 u value Double Glaze v 1.2 Triple Glaze

Cheers

A U-value of 1.0 is better than a U-value of 1.2 (w/m2k)

Triple is better than double

Solar reflectance etc can be managed and assuming it’s specified correctly triple is better than double.

Is there a salesman out there filling you with BS?

I think there is. Been told their Double glaze is better than triple due to new glass they are using for double glaze. Im sceptical to say the least.

Bs

Triple is down to 0.6

There selling crappy frames that suit double glazing

The frames is where the money is - they just buy in the glass

Lumen

Apart from a small cost factor, the only advantage to double is higher light transmittance. And weight, for a sliding door.

So cost, weight, transmittance.

What has double glazing ever done for us? :pac:

The thing is they are saying their triple is only 1.2 so in theory its best to go with double 1.0. Even if I am being fed rubbish I want to make sure Im getting the right one. This is my issue.

Go to a different company for your windows

Lumen the cost and transmittamce difference in the glass - 5-10% it’s not worth discussing. I’ve a 2x2.7m sliding door triple glazed - the weight can managed by the frame design.

B-D-P--

As above I got triple with 0.75 Uvalue

You need to make sure they give you the certification details..if they say they are certified they should have a registration number ...we made the mistake of not asking for it upfront...you also should get the specifications...I.e.what width is the glass...from what we have learned triple should be at least 44mm to be significantly better than some double glazing

Did you get replacement windows though?

Thinner panes are still acceptable in that situation. Typically 36mm (4-12-4-12-4)

TG for new dwellings should typically be 44mm min, some window sizes may require thicker panes in some instances.
