How To Cut Insulation

  • Make a straightedge from a 1-by-6 or 1-by-8 board, cutting it 12 to 18 inches longer than the width of the insulation.
  • Lay the insulation onto a scrap piece of plywood to protect the surface on which youre working. Be sure the faced sidethe side with the kraft paper or foil moisture barrieris facing down.
  • Measure the piece and add an extra inch for a tight fit, and then mark the insulation with a felt-tip marker.
  • Set the straightedge across the insulation, aligning it with the cut mark.
  • Kneel on one end of the straightedge and press down on the opposite end with your hand. Guide the utility knife along the straightedge to slice through the insulation. You may need to make two or three passes to cut all the way through.
  • Utility Knife with Snap-Off Blade
  • PRO TIP: To cut through thick batts, use a utility knife that has a snap-off blade . Extend the blade out about 3 inches, then tighten the locking knob. The extra-long blade makes it much easier to slice through thick insulation. Just be careful with this super-sharp, long blade!

    Fiberglass roofing panels are specially produced to thrive in harsh conditions that come with the territory of industrial, wastewater treatment, and commercial plants. But what sets them apart from traditional metal roofing and how could FRP better serve your work environment? Cost, weight, durability, and ease of installation are generally the most important factors when choosing a roofing material.

    Corrugated fiberglass is resistant to insect damage, rot, elevated temperatures, harsh chemicals, and more all while having high tensile strength. Additionally, fiberglass is extremely easy to work with as it may be cut, drilled, sawed, etc. without suffering damage and is easy to install.

    These are all major reasons why owners, maintenance, and plant personnel prefer corrugated FRP for their industrial applications.

    What Underlayment Should Be Used Under Metal Roofing

    Non-perforated, asphalt-impregnated felt has traditionally been used to provide roof underlayment on steep-slope metal roofs. The amount of felt underlayment used varies depending on the type of felt, ranging from organic reinforced to inorganic reinforced.

    Metal Roofing: The Pros And Cons

    A metal roof can be installed on your home to create a more modern appearance while lowering your utility bill. It is, however, critical to understand that roofing cannot be done with all types of metal. Before using metal roofing over plywood, you should thoroughly examine the plywood to ensure that it meets safety standards. Tyvek also has numerous advantages when compared to other types of metal roofing, such as its high durability and ease of installation.

    Rigid Foam Insulation Under Metal Roof

    Rigid foam insulation is a great option for metal roofs because it provides a high R-value, meaning it will keep your home or building cooler in the summer and warmer in the winter. It is also impervious to moisture, so it wont rot or grow mold and mildew.

    Is applying rigid foam under metal roof ok? This is done in preparation for the installation of Solar panels and rainwater harvesting. Roofs are generally outfitted with ventilation to avoid overheating of roofing materials. Will that be a concern with metal roofing?

    How To Insulate Walls

    Part 1 How to Install a Fibreglass Roof – GRP timber decking

    Walls are typically insulated with faced batt insulation because it comes precut into strips that fit standard 8-foot-tall walls. However, faced roll insulation is also perfectly acceptable. Youll just have to cut the strips to length to fit between each stud.

    Caution: Installing fiberglass insulation exposes you to fine glass fibers, which are irritating to the skin, eyes, and lungs. Whenever you handle the insulation, wear long pants, a long-sleeved shirt, tight-fitting eye goggles, gloves, and a dust mask, or better yet, a dual-cartridge respirator. To keep the itchy glass fibers from sticking to your neck, sprinkle baby powder onto the exposed skin around your shirt collar.

    There are a few different ways to slice through insulation, but the simplest method for do-it-yourselfers is to use a straightedge and utility knife as shown in the photo below.

    Laying The Chopped Strand Mat

    Before the chopped strand mat is laid out, the deck must be clean and dry and all the trims fixed in place. The mat has a cut edge and a feathered edge. Always overlap the feathered edge on top of the cut edge.

    The mat is usually best laid parallel to the drip trim. Start by rolling the mat out. Overlapping the trim by at least 50mm, but not over the edge of the trim. Leave the ends long at this stage.

    Roll out each 1m wide strip overlapping each time by at least 50mm right across the roof. The ends can be cut off with a Stanley knife into the corner of the trim to leave a straight and neat edge. Decide on the best place to finish laminating the roof from. Roll the mat up to the furthest point from the ladder.

    Leave the rolls on the roof where they have been laid out to avoid any mix up if there is a deviation in size or angle from one length of mat to another. Cut 200mm squares of mat for each corner and 200mm strips of bandage for each trim joint.

    How To Install High To Low Transition Trim For Metal Roofing

    Transition trim is used when you have a roof that has two different pitches. It’s located where the two different roof pitches meet so the metal roof does not leak.

    Transition flashing is also referred to as pitch break trim and comes high to low or low to high.

    When you have metal roofing sheets that are running up into a wall, you will need to install endwall flashing to help control the water runoff. It will prevent roof leaks at this vulnerable location.

    Endwall flashing must be installed after installation of the sidewall trim.

    Install Shingles Around Vents

    Roof around the vent. Cut the upper shingles so they fit snugly but do not ride up on the flashing’s raised portion the shingles should lie flat at all points. Where shingles overlap the flashing, attach them with roofing cement rather than nails. Cover any exposed nailheads with dabs of roofing cement.

    Editor’s tip: To roof around a dormer or other obstruction, install shingles all the way up and run at least one course past the obstruction. The bottom of these courses must be nailed higher than usual so you can slip shingles under them later. Now you can snap a new bond line to align the shingles on the other side.

    Laying Out The Fibreglass Mat

    Attic Insulation R50 Vs R60  Attic Ideas

    While the first layer of resin is still wet, its time to start rolling out the cut pieces of fibreglass matting and applying the top layer of catalysed resin. Each roll of matting is laid down, and coated thoroughly with the correct quantity of resin.

    As the laminate begins to turn transparent, a consolidation roller is used to ensure that the laminate sets correctly. In particular, at this point there is a risk of pinholes or resin starvation occurring, which can lead to leaks or water ingress in the roofing system.

    In extreme cases, these might require the entire roof to be started from scratch.

    Comparison Of Fiberglass Shingles

    So whats the difference between asphalt and fiberglass shingles? Fiberglass shingles are actually composed of asphalt as well, and when most people today say asphalt shingles, they are actually referring to fiberglass shingles.

    You will often see the terms used interchangeably. However, asphalt shingles can also refer to organic shingles.

    Traditional asphalt shingles have been waning in popularity in recent years and have, for the most part, fallen out of use.

    Their organic core is highly susceptible to rot and water damage. This paper base understandably also leads to a lower fire protection rating. They are also much heavier than fiberglass shingles, which makes them more difficult to work with.

    Fiberglass shingles are created with a woven fiberglass base as opposed to a wood-based one. This base mat is then covered with waterproof asphalt and granules of ceramic that help shield your roof from UV rays.

    Since the only difference is in the base, fiberglass and traditional asphalt shingling look identical as a finished product.

    Fiberglass asphalt shingles are more expensive than organic asphalt shingles but for a good reason. Their value as a roofing material is greater due to their increased durability and longevity.

    While a traditional asphalt roof may last only 10-15 years, and installation using fiberglass shingles can stretch the life of your roof a great deal ranging anywhere from 25 to 50 years! This makes the increased cost well worth it.

    Cleaning And Insulating The Roof

  • 1Sweep the roof clean of debris. Use a hard-bristled brush or leaf blower to remove as much dirt as possible. Get rid of all rocks, twigs, leaves, and other debris. If you notice stubborn debris, especially in cracks and around flashing, try scraping it off with a metal roof scraper.XResearch source
  • Any leftover debris can prevent the torch down roofing membrane from forming a waterproof seal, so make sure you remove it all before working on the roof.
  • Stay safe while on the roof. Climb up on a secure ladder with stabilizers that hook onto the roofs edge. Have someone else nearby in case you need help.
  • 2Remove the old flashing with a hammer. The old flashing hanging off the side of the roof needs to be removed so the new bitumen membrane seals correctly. The flashing is held in place by nails, so locate the nails then use the claw end of a hammer to pry them out.XResearch sourceAdvertisement
  • 3Flashing is an important part of waterproofing your roof, so take the time to replace it. You may be able to reuse newer, undamaged flashing, but usually replacing all the pieces at the same time is easier.
  • If the flashing is stuck under an old bitumen membrane, you may need to slice through the bitumen with a utility knife.
  • The mesh is available at many home improvement stores. You may wish to measure your roofs size first to ensure you purchase enough.
  • Make sure the nails hold the mesh securely and tightly to the roof so that water cant leak through it.

    Complete GRP / Fibreglass Roof Installation

    Glass Reinforced Polyester, also known as GRP fiberglass roofing, is mixed material and reinforced with first-class glass fibers. It is designed especially for flat roofing system applications and one of the most popular roofing types in the market. You can use it for domestic properties, from housing up to huge industrial buildings.

    Fiberglass roofing can be placed quickly and cover huge areas such as industrial complexes and warehouses. Many of the flat roofs you can see in commercial areas contain fiberglass.

    The simplicity and safe installation of GRP roofing and the finished product are known as having a longer lifespan than the felt roof.

    GRP roofs start with applying a resin catalyzed layer for the coating to have the best quality, then wait until the roof deck is completely dry . Then a sheet of fiberglass matting is placed on the top and followed by a second coating layer of resin catalyzed to complete the system.

    Advantages of Having GRP Roofing

    • Convenience: When we talk about the selection of roofing materials, nothing gets more convenient than fiberglass. The smooth nature of its form means no wastage, more environmentally friendly, less pressure on surroundings, and the best replacement to felt which is not often recycled. From the manufacturing site, the material can be pre-cut. Notably, the transport is fast, and the installation process is straightforward.

    Unit Costs: How Pros Price

    Unlike websites which blend pricing from dissimilar jobs, Homewyse creates custom estimates from Unit Costs. The Unit Cost method is based on job specific detail and current costs. Contracting, trade, design and maintenance businesses rely on the Unit Cost method for transparency, accuracy and fair profits.

    Applying The Grp Edge Trims

    Edge Trims are manufactured from GRP. One side of the trim will have a matt finish for high adhesion and the other side will be glossy.

    Most trims are fixed to the decking board with 13mm galvanised nails or staples. The exception to this is the application of the F300 Flat Flashing and D260 Fillet Trim. These should be fixed with a PU Adhesive.

    Shingle Peaks And Hips

    When you reach a peak or hip, shingle all the way up the first side and cut the 3-tab shingles just below the ridge. Shingle the other side and allow these pieces to overlap the ridge by no more than 4 inches.

    Editor’s tip: When hips meet at a ridge, you may have to improvise to handle awkward areas. Just be sure that water will not seep in between shingles as it runs downward. Where two hips meet a ridge, cut a triangular piece to cover the joint. Cover any exposed nailheads with dabs of roofing cement. Then apply ridgecaps.

    If you have a hip that runs into the main roof, cover the area with WSU when you are installing the sheathing cut the WSU so it lies flat at all points. Then cover the resulting V-shape notch with another piece of WSU. When you install the shingles, leave one shingle unnailed so you can later slip a ridgecap under it.
