Hi

  

 I am getting closer to finishing my avionics which  means windows are on the horizon. After reading the many posts regarding crazing  and other weld-on challenges, I am wondering what the the current consensus is  on window installs.

  

 I am leaning to Silpruf for the side / door windows but  that still leaves a big hunk of plexi upfront.

  

 Does anyone have a guide to window install that  eliminate / reduces the risks associated with Weld-on. Given that I live in  Canada, Weld-on may be difficult to get Weld-on so I may have to consider  alternatives.

  

 Inquiring minds need to know.

I used sika flex on 2 RV-10's with great success, and weld-on on 1 RV-10 with poor success.  So poor we had to replace 1 side window and the windshield.  

Of course, your results may vary.  Many people have had success with weld-on, but the margin for error is much less.

I used the same method that we used on the Cozy MKIV to install the windows in my -10,  epoxy mixed with flox.  Then followed up with 2 layers of 2.5" wide BID glass tape on the outside.  I have never heard of a window coming off a Rutan canard aircraft using this method.  Last year I replaced the glass in my Cessna and used Weld-ON to glue the compass mount to the new windshield.  Within a month crazing was apparent.  No way I was going to use that crap again!

Les, am currently replacing my windshield that I installed about three years ago.  During a very hot summer here in S. E. Texas, one day I opened my hangar door to discover crazing over the entire windshield.  What the ...

All I can think of is that the weld on 10 wouldn't allow expansion causing stress fractures.  Will be using silka-flex this time.

Just curious why few folks seem to have any interest in the Lord 7545A/E urethane adhesive Geoff located and tested to be as strong as Weld On without the negative aspects.

We were very happy with Silka flex too. The Glasair guys generally use Silka flex as their default choice.

If I am not correct please let me know on this but I believe all Sikaflex

material is a polyurethane base material 

And it only comes as a single component material. The Lord 7545A/E material

is a  2 part urethane material which has higher Heat deflection temperature

and is a harder material than the Silkaflex adhesives. I am not sure which

one people

Have used for installing the windows but the Lord is a very good solution.

It is very easy to clean up. Just use

A urethane reducers like PPG DT870. This will not hurt your windows but

works great on cleanup. I would always 

Chose a 2 part material over a single part any time when a strong bond or

durable surface is required. Using a 

Air cured type system is not as good in my opinion and experience.

I might add that Silka flex was our solution long before Geoff made his recommendation. I would generally give great weight to Geoff's suggestions regardless of the topic.

How much do you use on a -10, and where do you get it in smaller quantities?

I spent quite a bit of time looking for the Lord product in the smaller quantities but was unable to find it.  If anyone wants to split a larger order, please let me know.  I'm just about ready to pull the trigger with Van's recommendation.

    

   Thanks.

How many 50ml kits would be needed to do all?  Windscreen, doors and 

side windows?
