Anybody using Velox ?

The cheapest price I have had on Trespa is c. £85 per m2.  Some quotes were significantly higher (by about 25%).  There is also the cost of the corner profiles to consider.

Continued to shop around and think we have Trespa at under £65 per m2, excluding the metal corner profiles and fixings.  We are firming up on the quote but it looks by far the best quote we have had and is from a reputable supplier.

Regarding the Trespa. I have ordered some samples for my project. It looks like a nice product. Did you consider anything else similar ? Do you know the cost per square meter ?

Hi Tim, apologies I was looking back through posts and don't think I answered one of your questions.  Yes, we have looked at just about everything we could find on the market.  Initially we were going to use larch or cedar but have seen so many badly weathered (or over treated) examples locally and on the mainland that we were put off.  I would have happily used charred timber but with the anthracite Tata cladding the whole house would have been dark grey/black and we did not want that aesthetic.  I did a number of tests charring larch and cedar at home with good success.  I also looked at numerous composite products and the one we liked best, taking look, durability, fixing and corner/reveal profiles and ability to maintain into account was Trespa Pura.  Formica also do a good product but not yet in a flush profile.

Hi Tim,

 

There are a few reasons why we did it this way and I will try and work through them. 

a) there is an optimum point in the thremal profile of the wall for the windows to be placed in order to minimise the risk of condensation.  Unfortunately we did not have a thermal image profile for the walls but Internorm estimated that it was a certain distance in from the outside and this was directly above insulation and not above the concrete core;

b) if the windows (which have a u value of c. 0.75) are above the concrete core of the walls (which have a u value of c. 0.15) and not the insulation they will themselves act as a thermal bridge;

c) visually the window reveals look better at less than the 215mm plus cladding depth which would have been needed in order to have the windows resting on the concrete core and there is less opportunity for seagulls etc to use the reveals as a platform.  On the Continent they tend to have much deeper reveals but they also often have to accommodate external roller blinds.

 

The steel angle supports for the windows will act as a thermal bridge  however we insulated the supports as best we could and their direct physical contact is only with the window frames themselves.  Everything is, after all, a compromise and we hope we got the compromise about right.....

Thank you. I am also having external blinds on south side of house so thinking of making room in Velox and having window on the concrete.

Of those people using Velox has anyone got or applied for 10 year structural warranty?

We just got an application turned down by a well known company as:

 

"Unfortunately, Velox ICF is not a product which is approved by ourselves for warranty purposes. Although, they are accepted by LABC, our requirements are different as we cannot accept this product as they are not a member of IFCA."

 

I'm not sure what IFCA is - presumably nothing to do with inshore fisheries?

Who have you used??

thanks

[Mr Punter]

@Grendel maybe ask Velox who they suggest as their system has been used on a fair few houses and doubtless many / most would have warranties.

We had to go with CRL for our Velox build insurance as Velox had a delay in renewing their kitemarks, apparently due to moving from wire to fibreglass ties.  The CRL insurance was more expensive (primarily due to not getting them on board for the foundations stage) so Velox credited us with the difference between NHBC and CRL costs.

Looks like possible winding up petition for CRL according to posts on trust pilot.

We were about to take out their structural warranty, but then they have stopped answering their phones.

We have just received certification of inspections carried out from our nominated CRL inspector, which is a hopeful sign...

[Grendel]

With Velox window openings there is a Velox board each side and above, but not below. Does it not work to put a board down as an under window sill and then pour the concrete? If there is not a horizontal lower board do you have to stop the concrete pour every time you reach a window sill level?

If there is no lower horizontal board how do you support the window in the insulation layer??

 

Any thoughts?

Hi, one of the issues which has arisen with our Velox build is how to support the weight of the large triple glazed windows. I assume that this is an issue with most ICF builds.  The window frame is approximately 100mm deep.  At first floor level the window frame sits approximately 15mm in from the exterior 35mm Velox panel.  This means that it is resting entirely above the 180mm of exterior EPS insulation.  The attached picture shows the "angle" we are using at ground floor level (where there is only 80mm of EPS to ground FFL) to support the window frames, bolted through into the concrete floor.

I would be interested to hear what solutions other people have used in ICF builds.

I also triple glazed and some of my windows are huge. I went with a half and half approach generally and placed the window partially on the insulated form work and partially on the concrete for smaller windows. However with larger windows I decided to build a Newton block plint directly off the floor then insulated them to the exterior.

I have not submitted any pictures of our finished house so here are a few exteriors, with the landscaping almost finished.  There is a bit of estate railing, steel edging to the drive and a bit more topsiol required.  With the estate railing and the edging for the drive and flower beds we buy in the steel, my builders do the setting out and the heavy lifting and I do all the welding on site.  Thanks again for all the assistance and encouragement.

[Mr Punter]

That is a great looking house.  The cladding looks looks an expensive mix.  Are you pleased with the Trespa?

[D Walter]

Thanks Mr Punter.  We spent lots of time looking at timber cladding all over the place and particularly in coastal enviornments like ours and so much had weatherd badly (uneven with lots of blackening) that we decided on the Trespa.  Speaking to local builders the general impression was that timber cladding did not fare well in the Island.  Yes, very pleased so far and hopefully it will wear well.  The Tata steel cladding is also doing well so far but it is very early days.....

[Mr Punter]

Just now, D Walter said:

The Tata steel cladding

 

From the picture I thought it was pre patinated zinc.

[D Walter]

Well, you got the Trespa right so ?.  I did look at the zinc but very costly and more dependent on the quality of the fitting than with the Tata.

[Russell griffiths]

That looks excellent @D Walter???

Thanks Russell.  About 10 years from starting clearing the site to finishing.

We have used Trespa and Tata steel on our build and very pleased with them

[DillyDilly]

@Humpty Dumpty, am I right in assuming that you had several concrete pours ? how many pours are allowed / sensible ?

 

[zanvan]

I am looking for a solution to having to put timber cladding on the exterior of a single storey build to satisfy Heritage. Mortgage lenders do not like my original plan to go with ICF blocks with EPS on the outside and inside skin. 

 

I am now looking at Isotex, Velox, and Porotherm - I believe all of them would give me a non-combustible exterior skin with good insulation and a potential target SAP rating of 0.13. Please assume that I am choosing floor, glazing and roof options wisely that will contribute to this final rating. 

 

Has anyone any advice or actually built with any of these systems?

Welcome to BuildHub.

 

It's worth using the forum search function on the terms above (or using google and adding the term "site:buildhub.org.uk" - e.g., google "isotex site:buildhub.org.uk")

 

I'm sure there have been discussions of all these systems at one time or another.

You mean, your mortgage lender doesn't like EPS ICFs.  You could always shop around for a mortgage and stick to your original plan.

The alternative could be upping the spec of the cladding to a fire retardant variant.

 

Have also heard that some high street lenders will lend in ICF but not hands on self builds.  A self build with specialist contractors.

 

That being said, at the moment, they can just make up/change the rules on a whim in response to the financial climate so who really knows!
