HR++ PREMIUM insulated glass, 4 mm - spacer - #4 mm

HR++ glass, 4 mm - spacer (Argon) - #4 mm is double glazing that consists of two glass panes that are hermetically sealed together with a frame. This space between the panes is called the "cavity." For HR++ glass, this spacer is filled with Argon gas for better insulation. The first pane in the product name is placed on the exterior of the building, while the second pane has an HR coating on the interior side of the spacer (indicated by the # symbol) and is installed on the inside of the house/building.

Due to wind load and other external influences, a thicker pane is often chosen for the exterior side of the building than for the interior pane. The spacer is available in several widths. The choice depends on the space in your window frame. The width of the spacer also determines the insulation value and whether the pane falls under the HR, HR+, or HR++ category. A 12 mm spacer has an insulation value of 1.3 (U-value), which falls under "HR+ glass." If you choose 13 mm, it falls into the "HR++ category" (U-value 1.2).

Features of HR+(+) glass, 4 mm - spacer (Argon) - #4 mm:

• Double glazing (insulating glass) consisting of two glass panes with a gas-filled cavity:
  Exterior pane: clear glass 4 mm (exterior side of the building)
  Cavity: filled with Argon gas (type and width of the profile can be selected in the configurator)
  Interior pane: clear glass 4 mm with an HR coating on the interior side of the spacer (interior side of the building)
• The total glass thickness can be calculated after choosing the spacer width. Both glass thicknesses + spacer width = total pane thickness.
  In this case: 4 mm glass + spacer width + 4 mm glass
• The frame/spacer that creates the space between the glass panels is available in different types and widths
• The frame/spacer is bonded to the glass with a butyl sealant. The sealing around the glass is based on polyurethane or polysulfide (approximately 11 mm high)
• The type and color of the frame/spacer can be chosen in the configurator
• Standard available widths: 6 - 8 - 10 - 12 - 13 - 14 - 15 - 16 mm (18 and 20 mm have an additional cost)
• The glass size is determined by measuring the tight frame size and subtracting the perimeter clearance (usually 5 mm clearance on all sides).
  This equates to a total of 10 mm in height and 10 mm in width to subtract to arrive at the net glass size.
  This may vary depending on the frame and situation, so be sure to check this carefully according to the guidelines of NPR 3577
• Minimum deliverable size: 150 x 150 mm (price on request!)
  Minimum size available for order on the website: 195 x 350 mm
• Maximum deliverable size: 1410 x 2400 mm
• Maximum surface area in accordance with NEN2608 (area III up to 3 meters height): 2.29 m²
  --> consult the wind load tables to determine the correct glass composition for your situation
• This glass weighs 20 kg per m²
• The listed price is per m²
• Customizable in the glass configurator

HR+(+) glass, 4 mm - spacer (Argon) - #4 mm is:

• Custom made
• Delivered according to the specified requirements (note: production tolerances apply to glass!)
• Delivered to the delivery address. Pickup is also possible, the options are mentioned on the payment page

Points of attention:

• This composition cannot be made larger than a maximum of 2.29 m² per pane. This is due to the strength of the window, the risk of breakage and the largest possible surface area based on the wind load tables that take NEN2608 into account. For larger surfaces you will have to switch to thicker compositions
• There are wind load tables for the exact determination of the composition of the glass. These take into account the location of the building in the Netherlands, the height of glass installation and the built or unbuilt environment.
• Safety standards apply that determine whether safety glass should be used. You are at all times responsible for applying the safety standards and requirements applicable in your country!
  In the Netherlands, this includes NEN-3569:2011 (“Vlakglas voor gebouwen – Risicobeperking van lichamelijk letsel door brekend en vallend glas – Eisen” voor Nederland).

• Ensure that you use the correct glass deduction when ordering the insulating glass, according to NPR 3577
• Think carefully about the right glass size. Size changes are no longer possible once your order has gone into production
• For the production of custom glass, tolerances have been determined within the glass industry in terms of dimensions, quality and finish. These are industry-wide and are used by all glass companies. Please note that it is possible that glass may have a small size deviation (approx. 1 - 2 mm), and certain miniscule damages cannot always be claimed
• Install the glass according to NPR 3577. If not followed, the warranty on the insulating glass will be void. Use the correct glazing blocks, glazing tape, and glazing sealant
• Insulating glass is quite heavy; according to ARBO regulations, you are not allowed to lift more than 20 kg. The driver may need lifting assistance during delivery. You will need to arrange extra hands at the time of delivery
• NEVER place the glass directly on the floor. Always place something in between like a piece wood, blanket, or rug. The chance of damage is very high if the glass is placed on a hard surface. This also applies to contact with walls and other hard surfaces. Protect the glass, as it remains a fragile product
• Work with care, use the right tools, and the appropriate Personal Protective Equipment
• Guidelines for assessing complaints regarding the quality of insulating glass have been established. These guidelines are applied throughout the glass industry in the same way when assessing complaints. These guidelines can be found in the "downloads" tab on this product page
