5 Frequently Asked Questions about Glass Block Wall & Bar Installations
• Question 1 – Do I need special support underneath the wall? Usually not. Unless there is a problem with the floor already standard subfloor framing is usually enough to support the block wall.
• Question 2 – Can the walls be prefabricated? –Yes. Straight prefabricated walls make the project easier and less costly to perform. Rounded walls are generally built at the job site.

• Question 3 – Are these walls sturdy? How are the walls attached or anchored? Most block walls are tied into surrounding wall(s) using panel anchors or vinyl stack anchors every 3rd course (or 24"). Panel reinforcing or horizontal vinyl stack pieces provide additional stability.

• Question 4 – How do you make radius or angled walls? How are the ends and tops finished off? – With the development of glass blocks with angles, corners, and finished ends there is usually no need to use dissimilar materials to finish the sides and tops of your project.
• Question 5 – Are there blocks with 60 or 90 minute fire ratings, or ones that offer higher levels of security? – Yes. There are solid and 60 and 90 minute fire rated glass blocks with thicker faces providing increased resistance to bullets, noise reduction, improved protection against vandalism & graffiti, and better fire ratings.

4 Cost Saving Glass Block Wall Ideas
1. Look for a skilled "one stop shop" – Although some masons and general contractors do glass block wall installations, a specialty contractor who can coordinate and perform the project from beginning to end is best. We can start with your ideas and turn them into completed projects – working from initial design and layout, prefabricating wall sections (where possible) and finally installing the walls.

2. Free shipping on pre-made wall sections – Straight walls are easier and less costly to build and install. We supply and install prefabricated wall sections with our Vinyl Stack spacing system to reduce installation times and save money (they are anchored to a wall, siliconed together, and field grouted)
3. Use thinner series blocks – If possible consider using 3 1/8" thick blocks to reduce costs. We carry Wave pattern finished end blocks (which are often needed for glass block shower stall installations) from Mulia in the thinner series.

4. Consider both domestic and foreign block lines – Pittsburgh Corning, the only domestic manufacturer of blocks, has excellent quality and a very broad product line for walls. Mulia 4" series blocks are usually more cost effective and also offer the thin line end block to save cost on projects.
