How do frame in openings?
Fox Blocks has devel­oped the Fox Buck specif­i­cal­ly to frame open­ings such as win­dows and doors. The Fox Buck pro­vides insu­la­tion around the open­ing plus sup­port for the attach­ment of the win­dow or door.

Does EPS ‘off gas’?
EPS does not off-gas. Fox Blocks forms do not and nev­er have con­tained any CFC or HCFC prod­ucts. The forms are made by a steam process that uti­lizes pen­tene gas’ as a blow­ing agent. The blow­ing agent dis­si­pates from the prod­uct with­in 48 hours of man­u­fac­tur­ing. Fox Blocks forms are odor­less, do not dete­ri­o­rate, and do not off gas.
Does EPS absorb water?
No, EPS is a closed cell foam and does not act like a sponge or absorb water.
Does the EPS provide support for a wood sill plate?
No, the EPS has no struc­tur­al capac­i­ty to sup­port any loads. Wood sill plates must achieve the required bear­ing from the con­crete with­in the ICF. A wood plate that can­tilevers 13 over the EPS and bears 23 on the con­crete is allow­able. This can be done with a min­i­mum 2 x 6 plate. If a 24 plate is required, a taper top form should be used to extend the con­crete under the plate.
When is a Taper Top form required?
Taper Top forms are specif­i­cal­ly designed to pro­vide a larg­er bear­ing sur­face along the top of the wall. Typ­i­cal­ly, the increased bear­ing sur­face may be used to sup­port mason­ry, floor or roof loads. Taper top forms are used in the tran­si­tion from ICF to wood frame con­struc­tion and the taper top form would be the top form on the wall.
