installing new front oak veneer door into oak frame with a side lite each side. Glass with be double glazed to keep it snug but not sure on best and easiest way to glaze side panels. Have seen many types of glazing tape but not sure which is best as needs to be fully waterproof. Any comments or should i use silicone sealant. Have to admit tape looks easiest option..

Advice would be appreciated.

Have seen this done all different ways.....

The way we would do it, and advise , for warranty reasons, would depend on whether you have a self Draining system ( eg the bottom bead is sat up on plastic shims to allow water out ) .

If you have a self draining system then we would advise just Glazing Tape , to both sides of the sealed unit, doesn't matter if it sits proud of the bead ( into the visible glass area ) as you can cut this excerss off with a sStanley knife.

A non ' self draining ' system , we would advise , again the glazing tape, but also Low Modulus , neutral cure silicone ( usually clear), which would be applied to the gap betwen the edge of the sealed unit , and the edge of the frame. Basically put the sealed unit in using glazing tape , then before applying the second layer of tape ( for the beads ), fill any visible gap within the rebate with the silicone, this prevents any moisture getting to the actual ' seal ' of the unit. I know some will say that surely that is what the tape is for , but wood moves a lot in varying weather conditions....

As goes materials, any decent silicone, ( must be Low Modulus , Neutral cure though ).Brands such as Soudal or Silfix should be fine, but from experience we tend to find the Butyl Flexistrip, that Hodgsons sealants manufacture to be the best ' tape ' for wooden windows, this comes in White , MAhogany and Black ...If you can't find it , I am sure we could sell you some! :D
Ronnie, Thanks for response. This link is to the manufacturers spec sheet for frame.. Not really designed for straight glass but for wooden framed side panels. and fix before glazing. Thanks again JB..

Spoke with rediseals today, and they recommend Butyl tape followed witha thin bead of silfix U9 low mod sealant.. How does that sound .???
